Post-shift changes in pulmonary function in a cement factory in eastern Saudi Arabia. (1/360)

This cross-sectional study was conducted in 1992 in the oldest of three Portland cement producing factories in Eastern Saudi Arabia. The respirable dust level was in excess of the recommended ACGIH level in all sections. Spirometry was done for 149 cement workers and 348 controls, using a Vitalograph spirometer. FEV1, FVC, FEV1/FVC% and FEF25-75% were calculated and corrected to BTPS. A significantly higher post-shift reduction FEV1, FEV1/FVC% and FEF25-75% was observed in the exposed subjects. Multiple regression analysis showed a significant relationship between post-shift changes and exposure to cement dust but failed to support any relationship with smoking. These findings may indicate an increase in the bronchial muscle tone leading to some degree of bronchoconstriction as a result of an irritant effect induced by the acute exposure to cement dust.  (+info)

Criteria for the health evaluation of polymeric materials building. (2/360)

Various polymer-based synthetic materials have become increasingly ubiquitous in manufactured materials in the U.S.S.R. These release various chemical compounds to the ambient air. The maximum permissible concentrations that have been established for various hazardous chemicals in ambient air must be adjusted to account for the conditions of apartment life. Studies have been conducted to determine exactly what compounds are released and at what rate. Toxicological studies and studies of various physical and chemical properties are required to determine the health effects of these chemicals at concentrations at which they are expected to occur in apartments. More research has to be carried out in this field to further expand our knowledge, and we must beware of any introduction of new polymeric materials without first studying their contribution to possible detrimental health effects.  (+info)

Microfungal contamination of damp buildings--examples of risk constructions and risk materials. (3/360)

To elucidate problems with microfungal infestation in indoor environments, a multidisciplinary collaborative pilot study, supported by a grant from the Danish Ministry of Housing and Urban Affairs, was performed on 72 mold-infected building materials from 23 buildings. Water leakage through roofs, rising damp, and defective plumbing installations were the main reasons for water damage with subsequent infestation of molds. From a score system assessing the bioavailability of the building materials, products most vulnerable to mold attacks were water damaged, aged organic materials containing cellulose, such as wooden materials, jute, wallpaper, and cardboard. The microfungal genera most frequently encountered were Penicillium (68%), Aspergillus (56%), Chaetomium (22%), Ulocladium, (21%), Stachybotrys (19%) and Cladosporium (15%). Penicillium chrysogenum, Aspergillus versicolor, and Stachybotrys chartarum were the most frequently occurring species. Under field conditions, several trichothecenes were detected in each of three commonly used building materials, heavily contaminated with S. chartarum. Under experimental conditions, four out of five isolates of S. chartarum produced satratoxin H and G when growing on new and old, very humid gypsum boards. A. versicolor produced the carcinogenic mycotoxin sterigmatocystin and 5-methoxysterigmatocystin under the same conditions.  (+info)

DS86 neutron dose: Monte Carlo analysis for depth profile of 152Eu activity in a large stone sample. (4/360)

The depth profile of 152Eu activity induced in a large granite stone pillar by Hiroshima atomic bomb neutrons was calculated by a Monte Carlo N-Particle Transport Code (MCNP). The pillar was on the Motoyasu Bridge, located at a distance of 132 m (WSW) from the hypocenter. It was a square column with a horizontal sectional size of 82.5 cm x 82.5 cm and height of 179 cm. Twenty-one cells from the north to south surface at the central height of the column were specified for the calculation and 152Eu activities for each cell were calculated. The incident neutron spectrum was assumed to be the angular fluence data of the Dosimetry System 1986 (DS86). The angular dependence of the spectrum was taken into account by dividing the whole solid angle into twenty-six directions. The calculated depth profile of specific activity did not agree with the measured profile. A discrepancy was found in the absolute values at each depth with a mean multiplication factor of 0.58 and also in the shape of the relative profile. The results indicated that a reassessment of the neutron energy spectrum in DS86 is required for correct dose estimation.  (+info)

Exposure to MDI during the process of insulating buildings with sprayed polyurethane foam. (5/360)

Buildings are often insulated with sprayed-in-place polyurethane foam in spite of the fact that few studies have been carried out on exposure levels to isocyanates during the spraying process. This paper is meant to provide new data on personal exposure to methylene-bis (4-phenylisocyanate) (MDI) while dwellings and office buildings are being insulated with polyurethane foam. An impinger using a 1-(2-methoxyphenyl)piperazine toluene solution as absorbent was used to take personal samples for the sprayer and helper during indoor and outdoor applications. The analytical results show that the levels of exposure were significant, especially for the sprayer, with values of up to 0.077 mg m-3 and 0.400 mg m-3 during outdoor and indoor applications, respectively. The helper's exposure was always lower.  (+info)

Prediction of toxigenic fungal growth in buildings by using a novel modelling system. (6/360)

There is growing concern about the adverse effects of fungal bioaerosols on the occupants of damp dwellings. Based on an extensive analysis of previously published data and on experiments carried out within this study, critical limits for the growth of the indoor fungi Eurotium herbariorum, Aspergillus versicolor, and Stachybotrys chartarum were mathematically described in terms of growth limit curves (isopleths) which define the minimum combination of temperature (T) and relative humidity (RH) at which growth will occur. Each growth limit curve was generated from a series of data points on a T-RH plot and mathematically fitted by using a third-order polynomial equation of the form RH = a(3)T(3) + a(2)T(2) + a(1)T + a(0). This fungal growth prediction model was incorporated within the ESP-r (Environmental Systems Performance [r stands for "research"]) computer-based program for transient simulation of the energy and environmental performance of buildings. For any specified location, the ESP-r system is able to predict the time series evolution of local surface temperature and relative humidity, taking explicit account of constructional moisture flow, moisture generation sources, and air movement. This allows the predicted local conditions to be superimposed directly onto fungal growth curves. The concentration of plotted points relative to the curves allows an assessment of the risk of fungal growth. The system's predictive capability was tested via laboratory experiments and by comparison with monitored data from a fungus-contaminated house.  (+info)

Measurements of the effectiveness of dust control on cut-off saws used in the construction industry. (7/360)

Materials used in the construction industry frequently contain large quantities of silica. When they are cut or shaped with power tools considerable respirable dust can be produced. Three dust control systems for use with cut-off saws have been evaluated on site: wet dust suppression using mains water, the same system using water from a portable water tank, and local exhaust ventilation. The efficiency of water suppression on cut-off saws has been precisely quantified in controlled laboratory conditions by means of measurements with and without dust control. When dust control was used on-site, the mean concentrations of airborne silica were reduced by a factor of between three and seven, the accuracy being limited by the relatively high limit of detection for silica. All controls systems generally reduced respirable dust levels by at least 90%. Although the effectiveness of dust suppression did not depend on blade type, a diamond blade was more effective than a resin-bonded blade with the pressurised water system; cutting a slab with this type of blade could be completed before the water tank required repressurization. In laboratory tests, the application of water reduced the dust concentration to < 4% of its value without control. The method for monitoring the dust concentration was sufficiently sensitive to measure a difference in concentration produced during cutting in different directions. It is important, however, that the pressure in supply reservoirs is properly maintained, that the water is correctly applied and that it is used at the correct rate. If this is done effective dust control can be achieved.  (+info)

Mortality due to asbestos-related causes among railway carriage construction and repair workers. (8/360)

The objective of this study was to further clarify the cancer risk associated with asbestos exposure in railway carriage construction and repair. The cohort included 734 subjects employed between 1 January 1945 and 31 December 1969. Vital status was ascertained at 31 December 1997. Mortality was investigated in the time span 1970-97. Forty-two subjects (6%) were lost to follow-up and eight causes of death (4%) could not be ascertained. The overall mortality was not above the expected value. Among neoplastic diseases, excesses were observed for lung standardized mortality ratio (SMR) = 124; 90% confidence interval (CI) = 87-172; 26 obs), pleura (SMR = 1,327; CI = 523-2,790; 5 obs), larynx (SMR = 240; CI = 95-505; 5 obs), liver (SMR = 241; CI = 126-420; 9 obs), pancreas (SMR = 224; CI = 98-443; 6 obs) and multiple myeloma (SMR = 429; CI = 117-1,109; 3 obs). The observed excess of lung and pleural neoplasms can be causally related to asbestos exposure in the manufacture of railway carriages. A causal role of asbestos exposure in the raised SMRs from laryngeal and pancreatic neoplasms and multiple myeloma cannot be conclusively proven.  (+info)

Building contributes almost 40% of CO2 emissions and is a major contributor to the green house gas (GHG) emissions. Different types of construction materials possess a wide variation of embodied energy and emit CO2 at different magnitudes during its life cycle. Selection of appropriate construction materials can considerably cut down CO2 emissions and make our buildings more sustainable and energy efficient. The study is an attempt to address the issues of sustainable construction and how its selection of construction materials can reduce CO2 emissions and play an important role in reducing the impact of climate change directly or indirectly.. Growing global population and prosperity increase the demand for energy and materials. The growth in demand is approximately exponential, meaning that consumption grows at a rate that is proportional to its current value; for most materials it is between 3% and 6% per year. Exponential growth has a number of consequences. One is that consumption doubles ...

A growing population in Kenya demands expansion of housing facilities. Traditional burnt bricks, quarry stones, timber, and corrugated iron sheets remain the most commonly used construction materials in Kenya. Expanded Polystyrene (EPS) material derived from the distillation process of crude oil and is 100% recyclable, is an alternative construction material. Use of EPS material reduces the rate at which natural materials such as wood and stones are extracted from the environment, hence promoting sustainable development. EPS buildings are fast to construct, cost saving and have thermal characteristics that are suitable for areas with extreme weather conditions. Structurally, EPS materials have performed well for both low and high-rise buildings of up to ten floors. In Kenya, lack of governing standards and unawareness amongst industry players has hampered adaptability of EPS building materials. This paper discusses the potential of EPS as a construction material in Kenya. It is concluded that Kenya

Ground penetrating radar (GPR) is a technique that may be used to image the inside of a structure by collecting the echoes (or reflections) resulting from electromagnetic signals such as, for example, electromagnetic waves of typically high frequency, being radiated into the structure. Typically, the rebars inside of a reinforced concrete structure are strong radar wave reflectors. Locating deteriorated areas within a reinforced concrete structure may be accomplished by analyzing the reflections, particularly the amplitudes of the reflections, from the rebars in the reinforced concrete structure. Furthermore, the extent of deterioration of these located areas may be determined from such analysis. Significantly, the system and method described herein, when applied to determine the extent of deterioration of one or more areas of a reinforced concrete bridge deck, is effective even if a layer of asphalt is laminated to the surface of the reinforced bridge deck.

Since the late 1800s, asbestos has been available to consumers in numerous commercial goods throughout the United States . Because of its low conductivity, non-combustibility, superior insulation qualities and fairly low cost, asbestos was an ideal substance to be used in the production of construction materials for the building of homes, offices and other structures. One such construction material was asbestos finishing cement. Asbestos finishing cement, a mixture of asbestos fibers and material binders, was used to protect and add insulation to many structures of that time. Its even and pliable consistency made it very easy to apply to almost any surface or plane which rendered the compound a useful tool in the construction trade.. In 1977, the Consumer Product Safety Commission (CPSC) prohibited the manufacturing of most construction materials containing at least one percent of asbestos fibers. However, since this ban pertained only to new production of such materials, the existing stock ...
Press Release issued Jul 28, 2016: Construction Chemicals are chemical formulation used with cement, concrete or other construction material at the time of construction to hold the construction material together. These chemicals are mixed in a particular quantity with the construction materials so as to fulfill its functional, aesthetic, and design requirement of civil structures. Construction chemicals have become one of the important components of chemical industry playing an important role in global infrastructure development of the nation. Construction Chemicals are regarded as specialty chemical used while constructing any structures to increase their life and impart additional protection from environmental hazards. This chemical also minimizes the quantities of cement and water generally required during the construction.

2016 Society for Industrial Microbiology and Biotechnology. Microbial carbonate precipitation has emerged as a promising technology for remediation and restoration of concrete structures. Deterioration of reinforced concrete structures in marine environments is a major concern due to chloride-induced corrosion. In the current study, halophilic bacteria Exiguobacterium mexicanum was isolated from sea water and tested for biomineralization potential under different salt stress conditions. The growth, urease and carbonic anhydrase production significantly increased under salt stress conditions. Maximum calcium carbonate precipitation was recorded at 5 % NaCl concentration. Application of E. mexicanum on concrete specimens significantly increased the compressive strength (23.5 %) and reduced water absorption about five times under 5 % salt stress conditions compared to control specimens. SEM and XRD analysis of bacterial-treated concrete specimens confirmed the precipitation of calcite. The present ...
This paper proposes a simple model for predicting the development of deleterious expansion from alkali-silica reaction (ASR) in long-service concrete structures. This model is based on some composition and reactivity parameters related to ASR, including the long-term alkali contribution by aggregates to concrete structures. This alkali contribution was estimated by means of a laboratory extraction test, appositely developed in this study in order to maximize the alkali extraction within relatively short testing times and with low leaching solution/aggregate ratios. The proposed test is a modification of the Italian Standard test method UNI 11417-2 (Ente Nazionale Italiano di Normazione) and it consists of subjecting an aggregate sample to leaching with saturated calcium hydroxide solution in a laboratory autoclave at 105 °C. Nine natural ASR-susceptible aggregates (seven sands and two coarse aggregates) were tested and the following optimized test conditions were found: leaching solution/aggregate

The regulation of building materials and products for flammability is critical to ensure the safety of occupants in buildings and other structures. The involvement of exposed building materials and products in fires resulting in the loss of human life often spurs an increase in regulation and new test methods to address the problem. Flammability tests range from those in which the sample is ground to a powder prior to testing to the full-scale room comer test. Variations in test methods include the specific measurement of flammability parameters being considered, the intensity and characteristics of the fire exposure, the relative scale of the test specimen, and many other factors. As a result of specific details such as specimen orientation and fire exposure intensity, some existing regulatory test methods have been shown not to classify a type of building material or product in a manner consistent with full-scale tests that simulated actual conditions. Such failures have resulted in the ...

Asbestos is a word used to refer to any of six naturally occurring minerals made of silicon. All of these minerals are composed of long, thin, fibrous crystals, which can be woven into fabrics. Asbestos is highly resistant to fire and other sources of heat, and it strengthens building materials. As such, it was used in insulation, flooring, the creation of concrete, ductwork, and a variety of other materials used in building construction. However, the use of asbestos comes at a heavy price. When in a solid form, asbestos is not dangerous, but, when materials including asbestos are destroyed, they create a highly abrasive dust which can damage the lungs. Diseases that are linked to asbestos dust include mesothelioma (a type of cancer), pleuritis, asbestosis, pleural effusions, pleural placks, COPD, and pleural thickening. Since asbestos was used in a wide variety of construction materials until the 1980s, and continues to be used in some capacity in construction today, asbestos may be found in ...
Asbestos is a mineral fiber that has been used commonly in a variety of building construction materials for insulation and as a fire-retardant. EPA and CPSC have banned several asbestos products. Manufacturers have also voluntarily limited uses of asbestos. Today, asbestos is most commonly found in older buildings, in pipe and furnace insulation materials, asbestos shingles, millboard, textured paints and other coating materials, and floor tiles. Elevated concentrations of airborne asbestos can occur after cutting, sanding or other remodeling activities disturb asbestos-containing materials. Improper attempts to remove these materials can release asbestos fibers into the air in buildings, increasing asbestos levels and endangering people living in those buildings.. One way to effectively deal with known asbestos-containing materials in a commercial building is to implement an Operations and Maintenance (O&M) Plan. An O&M Plan efficiently meets applicable regulations and the desired levels of ...

0002] Interest in roofing of increased solar reflectance has gained momentum in recent years as a way to reduce summer cooling costs and to mitigate smog-producing urban heat island effects. The EPA Energy Star Initiative requires steep-slope residential roofing (e.g. asphalt shingles) to have a minimum solar reflectance of 0.25 initially and a 3-year aged solar reflectance of at least 0.15. Low slope roofing according to Energy Star must have an initial solar reflectance of 0.65 and a 3-year aged solar reflectance of at least 0.50. EPA Energy Star thermal emittance requirement for roofing (regardless of type and age) is 0.75 minimum. Californias Title 24 Initiative requires 3-year aged reflectance minimums of 0.20 for steep slope roofing, 0.70 for low slope roofing, and similarly requires a thermal emittance minimum of 0.75. Conformance to these reflectance and emittance requirements is possible for many types of asphalt shingles. Standard shingles surfaced with light-colored roofing ...
Because of its rapid growth, abundance, and ability to contribute to both environmental protection and economic growth, the use of bamboo as an alternative building material is ideal in most tropical Latin American countries [7]. In the Caribbean, Bambusa vulgaris is the most cultivated exotic species of woody bamboo [7]. Timing is an important first step when considering when to harvest bamboo for use as a sound building material. In order to ensure optimum strength and to avoid pest invasion, it is advised to harvest bamboo during the dry season when starch content in the bamboo sap is low [8]. In addition, bamboo that is 3-5 years old is ideal as a construction material [8], although other sources argue that bamboo must be between 4-7 years before harvesting [9]. Nevertheless, bamboo older than five years (or seven years according to Schröder), becomes harder, drier, less permeable, and begins to deteriorate faster [8][9]. One can identify a mature bamboo stalk by its color and absence of ...

During National Asbestos Awareness Week, April 1-7, I urge Americans to learn about the dangers of asbestos exposure.. Asbestos is a mineral fiber that occurs naturally in our environment; in rock and in soil. Because of its fiber strength and heat resistance, asbestos has traditionally been used in a variety of building construction materials, as insulation and as a fire retardant.. Activity that disturbs asbestos causes small asbestos fibers to float in the air. Inhaling these fibers leads to asbestos-related diseases. Three of the major health effects associated with asbestos exposure are lung cancer; mesothelioma, a rare form of cancer that is found in the thin lining of the lungs, chest, abdomen and heart; and asbestosis, a serious progressive, long-term, non-cancer disease of the lungs.. Anyone who disturbs asbestos is at risk. However, it is of special concern for construction, insulation, and demolition workers, pipefitters, boilermakers and others who might disturb asbestos found in old ...

Australia Court of Appeals upholds $500,000 mesothelioma death verdict.. Sydney, Australia(JusticeNewsFlash.com)-An Australia Court of Appeals upheld a record Dust Diseases Tribunal award against James Hardie a building material producer. The legal action was filed by Margaret Dawson, the 64 year-old wife and daughter of two asbestos materials workers at the building product plant who handled asbestos containing materials at work. The lawsuit alleged the construction material companys asbestos dust was carried home on the clothes of the company workers, and Dawson was exposed to the toxic asbestos fibers and particles while laundering their work clothes.. Dawson was diagnosed with mesothelioma, a fatal cancer caused by direct and secondary exposure to asbestos-containing products, in 2007 and died 8 months later from the fatal disease. According to the Asbestos Diseases Foundation of Australia, the ruling by the Dust Diseases Tribunal of $500,000 was a legal first. Hopefully the compensation ...
Single-wall carbon nanotube (SWCNT)-based materials represent the future aerospace vehicle construction material of choice based primarily on predicted strength-to-weight advantages and inherent multifunctionality. As such, it is prudent to pursue the development of SWCNT-based sensing strategies that can be integrated into structural material systems at any point in the component fabrication process, and in doing so produce multifunctional materials that will create further gains in payload capacity. We are exploiting the multifunctioanlity of SWCNTs to construct sensors capable of measuring several parameters related to vehicle structural health (i.e., strain, pressure, temperature, etc.). The structural health monitor (SHM) is constructed using conventional electron-beam and photolithographic techniques to deposit a series of electrodes separated by a few microns. SWCNTs are then deposited and aligned between the electrodes using various self-assembly techniques. Initial prototypes were constructed

Determination of thermoanalytical and thermophysical properties allows for the comprehensive characterization of building materials. Knowledge about such aspects as composition, mass loss (due, for example, to binder burnout), thermal expansion, sintering, softening point and thermal conductivity is critical in the development of new materials and helps to ensure that final products can meet the demands being placed upon them. Simultaneous Thermal Analysis (STA) is ideal for investigating issues such as the glass transition temperature of modified glass, phase transitions in plasters and mortars, and thermal decomposition behavior - also with instrumentation for Evolved Gas Analysis (EGA) coupled to the thermal analyzer. The expansion and shrinkage behavior of building materials, both during production and once in use, can be determined with Dilatometry. LFA and HFM are versatile methods for the precise determination of thermal diffusivity and thermal conductivity on samples both small and ...

VOC emission profile is an important parameter to describe the building materials and consumer products for their impact on indoor air quality (IAQ). Emission profiles are dependent on the test conditions. It is therefore very important to standardize testing conditions in order to compare emission factors and decay constants reported by various testing laboratories. Standard chamber test conditions (Chamber temperature of 23 C, relative humidity of 50 %, air change rate of 1 ACH, and specimen loading ratio of 0.4 m{sup 2}/m{sup 3}) have been proposed for using small environment chamber (0.05 m{sup 3}) by an international consortium research program led by the Institute for Research in Construction, NRCC. VOC emissions (excluding formaldehyde) from three building materials, a particleboard, a carpet with rubber backing and a vinyl floor tile were measured under above defined test conditions. Samples of the chamber air were collected using multi-sorbent tubes during the chamber tests, and ...

Asbestos is an extremely fibrous silicate substance employed in building function. This helps some construction to be stronger also enables the building to exist for lengthy . The asbestos is still a construction material used in building from early50s. Asbestos is so popular in those periods to use within the building work or refurbished construction all of contain the asbestos stuff. Asbestos is also used in insulation, and also asbestos-containing products are found in many businesses; along with most frequent asbestos services and products include automotive parts, tiles, cement, and fabrics. The poisonous compound used in consumer-goods is more harmful to the well-being of the person. On the previous decades, many deaths happened at the building work with the consequence of asbestos. Asbestos is pulled deeper to our lung tissue with just about every breath we inhale. Asbestos use is prohibited in 1999 of the quite a few deaths within the development business, and many people today suffer ...
Asbestos was a widely used material between the 1950s and 1980s, it is a naturally occurring fibrous material derived from metamorphic rocks; most of the asbestos in the UK would have originally been imported from Canada.. Asbestos is not only strong and flexible, but it also has a natural resistance to heat, fire, chemicals and electricity, these physical characteristics meant that as a construction material it was applied to a variety of products; estimates suggest that at its peak asbestos was used in over 3,000 products ranging from vinyl flooring, roofing tiles, insulation and even domestic appliances.. There are three types of Asbestos: Brown (Amosite), Blue (Crocidolite) and White (Chrysotile). A professional survey should be sought prior to the removal of the asbestos containing material (ACM), this will not only identify which type of asbestos it is, but will also identify the level of risk it posses to the occupants and therefore whether it should be removed as a matter of urgency of ...
Mesothelioma is caused by asbestos exposure. Asbestos, once regarded as a miracle mineral, was popular due its lightweight but tough characteristics as well as for its heat-resistant properties. This naturally occurring mineral was used in many commercial and consumer products, from construction materials such as cement, roofing shingles and insulation, to consumer and industrial applications such as hair dryers, automobile brake pads and pipe insulation ...
At the work site, the most demanding task for the assistant in terms of physical work is the manual transportation of bricks, blocks, and mortar (the manual lifting and carrying of materials and pushing/pulling wheelbarrows for more than four hours every working day). For the bricklayers the most demanding task in terms of physical work is one handed repetitive lifting of bricks (1-6 kg with bended lower back for more than four hours per day) or two handed lifting of blocks (6 to ,48 kg). Jäger and colleagues7 reported that an increase of the brick/block mass leads to an increase in the moment and compression curves of 20 Nm or 1 kN per 5 kg. Latza and colleagues8 found an increased risk of low back pain (PR = 2.6) for workers laying large sandstones (7-10 kg) for at least two hours a shift compared with workers laying no such sandstones, while Sturmer and colleagues9 found that more than 10 years working as bricklayer increased the chance of low back disorders by 2.3 times (95% CI 1.2 to 4.5) ...

The low atmospheric pressure and low oxygen content in high-altitude environment have great impacts on the functions of human body. Especially for the personnel engaged in complicated physical labor such as tunnel construction, high altitude can cause a series of adverse physiological reactions, which may result in multiple high-altitude diseases and even death in severe cases. Artificial oxygen supply is required to ensure health and safety of construction personnel in hypoxic environments. However, there are no provisions for oxygen supply standard for tunnel construction personnel in high-altitude areas in current tunnel construction specifications. As a result, this paper has theoretically studied the impacts of high-altitude environment on human bodies, analyzed the relationship between labor intensity and oxygen consumption in high-altitude areas and determined the critical oxygen-supply altitude values for tunnel construction based on two different standard evaluation systems, i.e., variation of

The construction industry is a complex work environment. The work sites are temporary and rapidly changing. Asbestos has been widely used in construction industry, but the risks were primarily detected in specialized trades, such as insulation workers and plumbers. Today, the majority of cases related to asbestos exposure will occur in other occupational groups in the construction industry. In a large cohort of Swedish construction workers, insulators and plumbers constituted 37% of all cases of pleural mesothelioma between 1975 and 1984 while they constituted 21% of the cases between 1998 and 2002. It is estimated that 25-40% of all male cases of pleural mesothelioma in Sweden are caused by asbestos exposure in the construction trades. There are many other known carcinogens occurring in the construction industry, including PAHs, diesel exhausts, silica, asphalt fumes, solvents, etc., but it is difficult to estimate exposures and thus the size of the risk. The risk of cancer is less easy to ...
Most re-siding projects are on older homes, so its a good bet youve seen your share of asbestos siding if you operate in the business of siding renovations. Asbestos is a silicate mineral that was commonly added to cement board siding for durability and resistance to fire and weather during the 1920s to 1980s.. Asbestos never rots and doesnt decompose, but asbestos is extremely brittle. Because of this, your experience with asbestos-sided houses may be working with those plagued by general weathering, hail damage, broken corners and cracked shingles.. While asbestos siding is considered one of the least harmful among all construction materials containing asbestos, it requires respect and due diligence. Disturbing materials that contain asbestos releases fibers into the air. Even though its outside, fibers can be unknowingly inhaled and trapped in the lungs or swallowed and embedded into the digestive track. Asbestos is a human carcinogen and can cause cancer, and the symptoms can take years ...
The roads constructed using waste plastic, popularly known as Plastic Roads, are found to perform better compared to those constructed with conventional bitumen. The Indian Centre for Plastics in the Environment (ICPE) has been promoting the use of plastic waste to construct asphalt roads. A few trial roads have been paved successfully by combining waste plastic with bitumen. Plastic roads mainly use plastic carry bags, disposable cups, and bottles that are collected from garbage dumps as an essential ingredient of the construction material. When mixed with hot bitumen, plastics melt to form an oily coat over the aggregate and the mixture is laid on the road surface like a normal tar road. ...
