Bus services remain paralysed for the fifth consecutive day on Monday with no resolution in sight with the Madras High Court ordering the transport employees to return to work immediately. But the High Court also issued a directive to the TN government not to terminate workers without its consent.. The transport unions disregarded the order of the Madras High Court and said the strike will continue until the government gave in to the workers demands in toto. Opposition DMK, Congress and IUML demanded an immediate solution for the problem by talks with the striking workers representatives.. If it is not resolved before Pongal, it will leave thousands of people disappointed as they cannot travel to their homes and participate in the annual harvest festival.. The government did its best to bring the situation to normal by hiring temporary drivers, but the problems only multiplied with couple of such drivers causing accidents. One driver was arrested in Chennai on Monday for causing death on ...

Second and third shift considerations are important for production planning and scheduling in most manufacturing facilities. A careful literature survey revealed that multiple workshift considerations have not been previously discussed for general aggregate production planning models. In this paper, we propose a mixed integer logic for permitting the opening or closing of second and third shifts of production within a generic model having linear and quadratic cost components. We illustrate the results of the model on a hypothetical data set. The model permits different costs for opening and closing the extra shifts and provides for a minimum required work force size for the extra shifts.

The Dutch Expert Committee on Occupational Safety has released its draft recommendations on occupational exposure limits for bisphenol A and for cadmium and its inorganic compounds. Regarding bisphenol A, DECOS considered there to be very limited evidence to support a non-monotonic dose-response relationship and therefore recommended a health‑based recommended occupational exposure limit (HBROEL) of 3.3 mg/m3 (inhalable fraction), based on a 13‑week inhalation study in rats, the critical effect being local toxicity in the nasal cavity. For cadmium and its inorganic compounds, DECOS reviewed the 2017 recommendation of the Scientific Committee for Occupational Exposure Limits (SCOEL), and considered the scientific basis of its OEL (of 1 µg/m3, inhalable fraction) to be insufficient. DECOS instead supported a previously‑defined biological limit value in the urine of 2 µg cadmium/g creatinine for the protection against kidney effects, and an OEL of 4 µg/m3 to prevent adverse effects on the ...

MENGISTU, H et al. Diffusive gradient in thin-films (DGT) as risk assessment and management tools in the Central Witwatersrand Goldfield, South Africa. Water SA [online]. 2012, vol.38, n.1, pp.15-22. ISSN 1816-7950.. Diffusive gradient in thin-films (DGT) technology was used to monitor bio-available metals and the tool was developed for risk-based pollution assessment and liability apportionment in the Witwatersrand Goldfields, South Africa, where there is widespread mine-related pollution. DGT technology is a passive sampling technique whereby metal species are selectively diffused from polluted water through a diffusion layer and trapped by an inner chelating resin, giving rise to time-weighted average concentrations. The results show that the concentrations of most hazardous metals recorded from grab samples are higher than values recorded from DGT samplers, resulting in inaccurate input information to risk assessors, the public and decision makers. DGT samplers deployed along upper, middle ...

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump. The impinger-filter sampler was made out of an impinger flask, containing a derivatization solution, coupled in series with a filter holder and a pump. Di-n-butylamine was used as derivatization reagent in both samplers to stabilize the reactive isocyanates and to enable mass spectrometric detection. The solvent free sampler is highly advantageous because of its user friendliness during field measurements, as ...

Results: The sampling and analytic methodology used in the study presents the potential to characterize nanoparticle exposure for a variety of operational processes. We found the highest mass exposure occurred at bagging job whereas the highest number and surface area concentration was found at modification. Modification is suspected to be the primary emission source. It is discovered nanoparticles in the size range of 20-300nm dominate in this workplace, which consists of 90-98% of particle counts in the respirable fraction. Based on the sampling results from 2012, there was a strong relationship between number concentration in 5-25um range and the respirable mass concentration (r= 0.908); however, no such correlation was found between number concentration in nanoscale and respirable mass (r= 0.018). The deposited surface area in TB (r=0.66) and alveolar region (r=0.46) was modestly correlated with number concentration of particles in the nanoscale ...

The review of the Oil and Gas plant studies has allowed us to identify an opportunity to enhance the initial exposure information by recommending the next steps for industrial hygiene and occupational exposure information by recommending the next steps for industrial hygiene and occupational exposure assessment. A cumulative assessment should be performed that groups the chemical substances identified at Oil and Gas plant into two groups. Group 1 would be chemicals that exhibit classic dose response curves and are non-carcinogenic. The other group, group 2, would be identified carcinogens. Chemicals in Group 1 should be further assessed and subdivided into chemicals published TLVs and those without, and then grouped by systemic toxicology class to allow for the calculation of a cumulative exposure. Control banding methods can then be applied to estimate and assign an exposure hazard category.. Group 2 chemicals, the carcinogens, could be analysed and evaluated using method applied in Chen et ...

Introduction: To date, occupational exposure assessment of electromagnetic fields (EMF) has relied on occupation-based measurements and exposure estimates. However, misclassification due to between-worker variability remains an unsolved challenge. A source-based approach, supported by detailed subject data on determinants of exposure, may allow for a more individualized exposure assessment. Detailed information on the use of occupational sources of exposure to EMF was collected as part of the INTERPHONE-INTEROCC study. To support a source-based exposure assessment effort within this study, this work aimed to construct a measurement database for the occupational sources of EMF exposure identified, assembling available measurements from the scientific literature. Methods: First, a comprehensive literature search was performed for published and unpublished documents containing exposure measurements for the EMF sources identified, a priori as well as from answers of study subjects. Then, the ...

Engineering Controls: Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source.. Administrative Controls: Respiratory Protection: Seek professional advice prior to respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear a MSHA/NIOSH-approved respirator. Select respirator based on its suitability to provide adequate worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or nonroutine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. If respirators are used, OSHA requires a written respiratory protection program that includes at least: medical ...

A solution to avoid unsafe storage of ethylene cylinders Ethylene is the simplest unsaturated hydrocarbon and one of the chemical most used worldwide. Like all hydrocarbons, it is asphyxiating and flammable. Whatever the final employment, ethylene is distributed, stored and consumed in airtight systems always at high pressure. The fact that ethylene is asphyxiating, extremely flammable and explosive at 27.000 ppm renders the usage of ethylene quite dangerous. (Sigma-Aldrich MSDS sheet) (R A Strehlow, INT SYMP ON COMB, 14(1):1189-1200, 1973) Ethylene handling requires many precautions: the employees of every manufacturing facility must attend an advanced training program, unnecessary ethylene exposure must be limited and safety equipment have to be present in every facility for this reason. Because of ethylene asphyxiating characteristic, the American Conference of Governmental Industrial Hygienists adopted a Threshold Limit Value of 200 ppm for ethylene as an 8-hour time-weighted average. ...

For researches on toxic chemicals in settled indoor dust, selection of dust fraction is a critical influencing factor to the accuracy of human exposure risk assessment results. However, analysis of the selection of dust fraction in recent studies revealed that there is no consensus. This study classified and presented researches on distribution of toxic chemicals according to dust particle size and on relationship between dust particle size and human exposure possibility. According to the literature, beyond the fact that there were no consistent conclusions on particle size distribution of adherent fraction, dust with particle size less than 100 mu m should be paid more attention and that larger than 250 mu m is neither adherent nor proper for human exposure risk assessment. Calculation results based on literature data show that with different selections of dust fractions, analytical results of toxic chemicals would vary up to 10-fold, which means that selecting dust fractions arbitrarily will ...

Introduction. The common approach in risk assessment of water bodies is to collect a sample of the water, which is then analysed for potential pollutants in the laboratory. This approach, among other advantages, provides manageable control over accuracy and precision of the results. However, information obtained from spot water samples is only about concentration levels at the time of sampling and may fail to account for episodic contamination. This can be addressed by collecting a series of samples over a time period to obtain a more representative picture of water quality, but the cost of analysis is then increased. An alternative and more cost-effective approach is to obtain time-weighted average (TWA) concentrations of pollutants using passive samplers. Passive samplers are now seen as an alternative to conventional spot samples. This is seen by a number of recent reviews on passive samplers (Vrana et al., 2005; Lu et al., 2002; Petty et al., 2000; Stuer-Lauridsen, 2005; Chimuka and ...

Smoke, paint fumes, cleaning agents, and lead paint dust are a few of the many airborne-contaminants that can cause serious occupational-related disease to exposed workers. When airborne contaminants cannot be controlled by engineering means, respirators may used to reduce worker exposure to airborne inhalation hazards. When properly selected, fitted, and used, respirators can be an effective method of controlling worker exposure to air contaminants that pose a hazard.. Unfortunately, respirator use often occurs without the proper preparation. When used incorrectly, respirators will provide a false sense of security for the worker and may put the user at a serious health risk.. This CIRMA training and education program provides a thorough reviews of the OSHA respirator standard and guides municpal employers on the proper use of respirators and the establisment of a respirator prorgam.. ...

The standard provides a comprehensive and complex regulatory scheme for protecting construction workers from exposure to respirable crystalline silica containing dust. The scope of the standard applies to all occupational exposures to respirable crystalline silica and significantly lowers the permissible exposure limit (PEL) from 250 micrograms/m3 to 50 micrograms/m3. In addition to the new PEL, contractors will also have to comply with a host of ancillary provisions such as respiratory protection (when required by the standard), housekeeping, medical surveillance, and recordkeeping ...

Although U.S. OSHA updated its occupational silica standard in 2016 for the first time in 45 years, relatively few countries have followed suit. Aside from a handful of European countries, some Canadian Provinces and Mexico, most other countries do not have as stringent of a standard as the current U.S. Permissible Exposure Limit of 0.05 mg/. In fact, most low and middle-income countries have no regulatory limits for respirable crystalline silica in the workplace. Globally, occupational exposure standards for silica vary considerably and few have . . .

Organic dust consists of particles with a biological origin. Airborne levels of bacteria, fungi, endotoxins, and glucans have been investigated in epidemiological studies of mucous membrane irritation, inflammation, and airway obstruction. Organic dust can be measured by gravimetry of filter samples. Microorganisms can be quantified by culture, microscopic, and DNA-based methods. Culture methods underestimate microbial exposure and have poor precision. However, high sensitivity and identification of species that indicate fungal contamination have advantages in indoor air studies. Microscopic and DNA-based methods quantify microorganisms independent of cultivability. Specific organisms can even be quantified with molecular techniques. Quantification of specific organic dust components is preferred to dust levels. However, no occupational exposure limits exist for specific agents, although criteria for endotoxin and fungal spores have been proposed. In exposure assessments of microbial agents, ...

Background According to the ECHA Guidance on Information Requirements and Chemical Safety Assessment - Chapter R.8 (Version 2.1, Nov 2012), a national occupational exposure limit (OEL) can be used as a surrogate for a DNEL under certain circumstances (R.8.1.1). APPENDIX R. 8-13 is specifying the derivation of DNELs, when a community/national occupational exposure limit (OEL) is available. For 4,4´-MDI and pMDI the German MAK Commission established a purely health based OEL (MAK-Value) of 0.05 mg/m3for inhalable aerosol referring to an 8-hour exposure period, that is the basis for the official national OEL in Germany (listed in TRGS 900). This OEL is used as a surrogate DNEL for long-term exposure. A ceiling limit value of 0.1 mg/m3was settled. This ceiling limit is used as a surrogate DNEL for short-term exposure. Since irritation to the respiratory tract is the most sensitive health effect these DNELs apply for local effect, in absence of any systemic toxicity no additional systemic DNELs need ...

Vikings head coach Mike Zimmer told ESPN that he anticipates Bradford will be ready to go for the Week 5 divisional matchup.. Chicago Bears fans will get their first taste of what Mitchell Trubisky can do when he makes his regular season debut on Monday night, but there will be at least one more reason to tune into the game.. Otherwise, Case Keenum will start.. The Bears cornerback has been targeted frequently through Chicagos first four games, and either Keenum or Bradford could look to go after Fuller on Monday night with either Stefon Diggs or Adam Thielen lined up across from the corner.. The Mike Glennon experiment - despite the $18.5 million guaranteed the Bears gave him to sign in the offseason - appears to be over after just four games, during which he turned the ball over eight times. Mitch Trubisky can escape from pressure and keep plays alive. McKinnon will have 50 yards rushing also. Join the With the First Pick team! Running backs Jordan Howard and Tarik Cohen will have a rough ...
