The effects of strapped spectacles on the fit factors of three manufactured brands of full facepiece negative pressure respirators. (1/186)
A study was conducted to determine the effects of strapped spectacles on the fit factors obtained during quantitative fit testing on three different brands of full facepiece negative pressure respirators. The three brands of respirators were evaluated with and without strapped spectacles worn by the test subjects. A total of 180 quantitative fit testing trials were conducted on ten male test subjects. For each test subject, three quantitative fit testing trials were performed with each brand of respirator with and without the spectacles. The average of the fit testing trials for each subject with each respirator was used for statistical analysis. The results demonstrated that the fit factor values were significantly lower during use of the spectacles (p < 0.05). The estimated percentage of test subjects who failed the American National Standards Institute pass/fail criteria for quantitative fit testing (1000) increased by 15-36% when spectacles were worn. (+info)Respirator leakage in the pharmaceutical industry of northwest England. (2/186)
Field qualitative fit tests were conducted at 10 separate companies in the Northwest of England to determine the proportion of leaking respirators in a cross-section of pharmaceutical manufacturing industries. The 3 M FT-10 Qualitative Fit Test Apparatus was used to test a total of 211 half-face particulate respirator wearers. Participants wore their own respirators and were asked to don them as they would normally. In all cases, no specific intervention had occurred prior to testing. Results indicated a failure rate of 69% (of the 211 subjects tested, 145 respirators were leaking). Successful results were not associated with the frequency of use (p = 0.71) or years of experience wearing respirators (p = 0.59). Similarly, successful results were not associated with respirator training in the current job (p = 0.38) or training in previous jobs (p = 0.49). Leakage was not consistent across the 10 companies, with two companies exhibiting a 100% failure rate while another company had 26 successful tests in 50 wearers (52% pass rate). Only 35 of the 211 participants performed a negative pressure test. Of these, 80% successfully passed the test, which was significantly greater than the 22% pass rate among those who had not performed the pressure test (p < 0.001). (+info)Clinically important FEV1 declines among coal miners: an exploration of previously unrecognised determinants. (3/186)
OBJECTIVES: The relation between occupational exposure to dust and loss of ventilatory lung function is now well established. However, many exposures during work and other activities might also have important roles in determining clinically important losses of lung function. In this study, we attempted to explore additional plausible determinants of exposures and other potential risk factors for clinically important decline in forced expiratory volume in 1 second (FEV1) during work in dusty trades. METHODS: The study was performed in 264 underground coal miners whose lung function had been followed up for an average of 11 years. With an extensive follow up questionnaire, miners were asked about their occupational and non-occupational exposures, smoking, personal and family medical history, and living conditions during childhood. RESULTS: Several variables of the mine environment (as well as previously recognised effects of mining work and region) were found to be associated with excess decline in FEV1, including work in roof bolting, exposure to explosive blasting, and to control dust spraying water that had been stored in holding tanks. Use of respiratory protection seemed to reduce the risk of decline in FEV1. Other factors that were found to be associated with declines in pulmonary function included smoking, body mass, weight gain, childhood pneumonia, and childhood exposure in the home to passive tobacco smoke and possibly smoke due to wood and coal fuels. Miners with excessive decline in FEV1 were less likely to be working in mining jobs at follow up. CONCLUSIONS: These findings suggest the existence of additional risk factors for decline in lung function in dusty trades, and may be useful in developing additional approaches to the prevention of chronic respiratory disease. (+info)Two patients with occupational asthma who returned to work with dust respirators. (4/186)
OBJECTIVES: To assess the efficacy of dust respirators in preventing asthma attacks in patients with occupational asthma (asthma induced by buckwheat flour or wheat flour). METHODS: The effect of the work environment was examined in two patients with occupational asthma with and without the use of a commercially available mask or a dust respirator. Pulmonary function tests were performed immediately before and after work and at 1 hourly intervals for 14 hours after returning to the hospital. RESULTS: In patient 1, environmental exposure resulted in no symptoms during and immediately after work, but coughing, wheezing, and dyspnoea developed after 6 hours. Peak expiratory flow rate (PEFR) decreased by 44% 7 hours after leaving the work environment, showing only a positive late asthmatic reaction (LAR). In patient 2, environmental exposure resulted in coughing and wheezing 10 minutes after initiation during bread making, and PEFR decreased by 39%. After 7 hours, PEFR decreased by 34%. The environmental provocation tests in both patients were repeated after wearing a commercial respiratory. This resulted in a complete suppression of LAR in patient 1 and of immediate asthmatic reaction (IAR) and LAR in patient 2. CONCLUSIONS: Two patients with asthma induced by buckwheat flour or wheat flour in whom asthmatic attacks could be prevented with a dust respirator are reported. Dust respirators are effective in preventing asthma attacks induced by buckwheat flour and wheat flour. (+info)Fit factors for quarter masks and facial size categories. (5/186)
Respirator fit testing is necessary before entering hazardous working environments to ensure that the respirator, when worn, satisfies a minimum fit and that the wearer knows when the respirator fits properly. In the many countries that do not have fit testing or total inward leakage regulations (including Korea), however, many workers wearing respirators may be potentially exposed to hazardous environments. It is necessary to suggest a useful tool to provide an alternative for fit testing in these countries. This study was conducted to evaluate fitting performance for quarter-mask respirators, and fit factors in facial size categories based on face lengths and lip lengths of the wearers. A total of 778 subjects (408 males, 370 females) were fit tested for three quarter masks: Sejin Co. SK-6 (Ulsan, Korea), Yongsung Co. YS-2010 S (Seoul, Korea), and 3 M Co. Series 7500 Medium (MN, USA) masks with a PortaCount 8020 (TSI Co., USA). A facial dimension survey of the subjects was conducted to develop facial size categories, on the basis of face length and lip length. Geometric mean fit factors (GMFFs) of Series 7500 Medium were found to be the highest of the three respirators. All of the respirators were more suitable for males than females in fitting performance. The Series 7500 Medium fitted a large number of the males tested, since the GMFFs for males were above 100 for every box of facial size categories, and high pass proportion rates were shown at an individual fit factor level of 100. The YS-2010 S provides an adequate fit for males in a limited range of facial dimensions. The Series 7500 Medium is more limited in providing adequate fit for females at specific facial dimensions than for males. For adequate fitting performance, the SK-6 is not preferentially recommended for Korean male and female workers due to low GMFFs and pass proportions. The result of this study indicates that after more accurate studies are performed, facial size categories, on the basis of facial dimensions, could be a useful tool to assist in the selection of adequately fitting respirators for workers in the countries having no fit testing requirements. (+info)Performance of respirator filters using quality factor in Korea. (6/186)
A respirator filter of good quality has not only high aerosol collection efficiency but also low air resistance. "Quality factor", which is expressed with aerosol penetration and pressure drop, can be used to rank the performance of respirator filters within the same category. This study focuses on evaluating several respirator filters which are widely used in Korea using quality factor. Two mechanical filters and three filtering facepieces made by different manufacturers were measured aerosol penetrations and pressure drops by an automatic filter tester (CertiTest Model 8110, TSI Inc., St. Paul, USA) at four flow rates of 10, 32, 64 and 85 L/min. NaCl aerosols used were reported to be mean size of 0.1 microm and geometric standard deviation of <1.9. The penetrations and pressure drops of all filters have strong flow rate dependency. The filter quality factors decrease sharply as flow rates are increased. The mechanical filter S and filtering facepiece M are shown better filter quality than others in the same category. Since some certified filters are found to be inappropriate in the workplace exposed to fume, this result suggests that the current certified filter test protocol for respirators should be changed for the new protocol using smaller aerosols. (+info)Cyclohexane as an alternative vapor of carbon tetrachloride for the assessment of gas removing capacities of gas masks. (7/186)
An alternative vapor was explored to replace carbon tetrachloride (CCl4) for testing breakthrough times of cartridges and canisters of gas masks in the National Approval Test of Respirators. Cyclohexane was single out as a candidate for the alternative vapor out of six vapors: trichloroethylene, n-pentane, n-hexane, n-heptane, toluene and cyclohexane from the viewpoints of similarity of vapor pressure and water-solubility to CCl4, lower toxicity than CCl4, and technical feasibility in generating an airflow of 30 L/min containing the vapor ranging from 300 to 5000 ppm. Breakthrough times of cartridges and canisters were examined by generating cyclohexane vapor in a test airflow of 30 L/min in comparison with CCl4 vapor under various test conditions with different vapor concentrations and relative humidities (RH). As the results, the breakthrough times of the cartridges and canisters for cyclohexane were found to almost coincide with those for CCl4 under all examined range of concentrations and RH. By an increase of humidity from 50% RH to 80% RH, the cartridges showed significant shortening of breakthrough times for both of CCl4 and cyclohexane, but the susceptibility of the breakthrough time of cyclohexane to humidity was also similar to that of CCl4. It was, therefore, concluded that cyclohexane can be recommended as the alternative vapor of CCl4 for testing the breakthrough times of gas mask cartridges and canisters in the National Approval Test.

Introduction of personal protective equipment (PPE) in the process of quantitative exposure and risk assessment should be addressed carefully. PPE which have been designed and manufactured according to CE-criteria and have proved to pass relevant test criteria, can be classified as "proper functioning". However, test criteria for PPE are not equal to levels of protection which can be achieved in the workplace, because actual workplace exposure scenarios, fit, maintenance and storage may differ substantially from the test conditions. The proper use of PPE is related to issues which form a part of a PPE-programme. Such a programme should be implemented in a company to ensure selection of proper PPE and information, training and instruction of employees how to wear PPE properly. Assigned protection factors (APFs) for different designs of respiratory protective devices (RPD) have been introduced to quantify effectiveness of RPD in the workplace. Similar APFs are proposed for dermal protection (gloves and clothing). In general biological monitoring studies show lower reduction of internal exposure than estimated by reduction of external exposure. Therefore, conservative estimates of protection by PPE, i.e. the lowest APFs, are proposed for risk assessment purposes if "proper use of proper functioning" PPE as part of a PPE-programme cannot be demonstrated. (+info)Respiratory Protective Devices (RPDs) are personal protective equipment items designed to protect the user from inhalation of hazardous substances or harmful levels of airborne contaminants in the environment. These devices create a physical barrier between the user's respiratory system and the surrounding air, filtering out or purifying the air before it is breathed in.
RPDs can be categorized into two main types:
1. **Air-purifying Respirators (APRs):** These devices use filters, cartridges, or canisters to remove contaminants from the surrounding air. They are further divided into several subcategories, including filtering facepiece respirators, half-mask elastomeric respirators, full-facepiece elastomeric respirators, and powered air-purifying respirators (PAPRs).
2. **Supplied-Air Respirators (SARs):** These devices deliver clean breathing air from an external source, either through a compressor or compressed air cylinder. They are further divided into two subcategories: self-contained breathing apparatuses (SCBAs) and supplied-air respirators with escape provisions.
The choice of RPD depends on the nature and concentration of the airborne contaminants, the user's physiological and psychological capabilities, and the work environment. Proper selection, fitting, use, maintenance, and training are crucial to ensure the effectiveness and safety of Respiratory Protective Devices.
Filtration in the medical context refers to a process used in various medical treatments and procedures, where a substance is passed through a filter with the purpose of removing impurities or unwanted components. The filter can be made up of different materials such as paper, cloth, or synthetic membranes, and it works by trapping particles or molecules based on their size, shape, or charge.
For example, filtration is commonly used in kidney dialysis to remove waste products and excess fluids from the blood. In this case, the patient's blood is pumped through a special filter called a dialyzer, which separates waste products and excess fluids from the blood based on size differences between these substances and the blood cells. The clean blood is then returned to the patient's body.
Filtration is also used in other medical applications such as water purification, air filtration, and tissue engineering. In each case, the goal is to remove unwanted components or impurities from a substance, making it safer or more effective for use in medical treatments and procedures.
Protective devices, in the context of medical care, refer to equipment or products designed to prevent injury, harm, or infection to patients, healthcare workers, or others. They can include a wide range of items such as:
1. Personal Protective Equipment (PPE): Items worn by healthcare professionals to protect themselves from infectious materials or harmful substances, such as gloves, masks, face shields, gowns, and goggles.
2. Medical Devices: Equipment designed to prevent injury during medical procedures, such as tourniquets, safety needles, and bite blocks.
3. Patient Safety Devices: Items used to protect patients from harm, such as bed rails, pressure ulcer prevention devices, and fall prevention equipment.
4. Environmental Protection Devices: Equipment used to prevent the spread of infectious agents in healthcare settings, such as air purifiers, isolation rooms, and waste management systems.
5. Dental Protective Devices: Devices used in dental care to protect patients and dental professionals from injury or infection, such as dental dams, mouth mirrors, and high-speed evacuators.
The specific definition of protective devices may vary depending on the context and field of medicine.
Ear protective devices are types of personal protective equipment designed to protect the ears from potential damage or injury caused by excessive noise or pressure changes. These devices typically come in two main forms: earplugs and earmuffs.
Earplugs are small disposable or reusable plugs that are inserted into the ear canal to block out or reduce loud noises. They can be made of foam, rubber, plastic, or other materials and are available in different sizes to fit various ear shapes and sizes.
Earmuffs, on the other hand, are headbands with cups that cover the entire outer ear. The cups are typically made of sound-absorbing materials such as foam or fluid-filled cushions that help to block out noise. Earmuffs can be used in combination with earplugs for added protection.
Both earplugs and earmuffs are commonly used in industrial settings, construction sites, concerts, shooting ranges, and other noisy environments to prevent hearing loss or damage. It is important to choose the right type of ear protective device based on the level and type of noise exposure, as well as individual comfort and fit.
Occupational air pollutants refer to harmful substances present in the air in workplaces or occupational settings. These pollutants can include dusts, gases, fumes, vapors, or mists that are produced by industrial processes, chemical reactions, or other sources. Examples of occupational air pollutants include:
1. Respirable crystalline silica: A common mineral found in sand, stone, and concrete that can cause lung disease and cancer when inhaled in high concentrations.
2. Asbestos: A naturally occurring mineral fiber that was widely used in construction materials and industrial applications until the 1970s. Exposure to asbestos fibers can cause lung diseases such as asbestosis, lung cancer, and mesothelioma.
3. Welding fumes: Fumes generated during welding processes can contain harmful metals such as manganese, chromium, and nickel that can cause neurological damage and respiratory problems.
4. Isocyanates: Chemicals used in the production of foam insulation, spray-on coatings, and other industrial applications that can cause asthma and other respiratory symptoms.
5. Coal dust: Fine particles generated during coal mining, transportation, and handling that can cause lung disease and other health problems.
6. Diesel exhaust: Emissions from diesel engines that contain harmful particulates and gases that can cause respiratory and cardiovascular problems.
Occupational air pollutants are regulated by various government agencies, including the Occupational Safety and Health Administration (OSHA) in the United States, to protect workers from exposure and minimize health risks.
Occupational exposure refers to the contact of an individual with potentially harmful chemical, physical, or biological agents as a result of their job or occupation. This can include exposure to hazardous substances such as chemicals, heavy metals, or dusts; physical agents such as noise, radiation, or ergonomic stressors; and biological agents such as viruses, bacteria, or fungi.
Occupational exposure can occur through various routes, including inhalation, skin contact, ingestion, or injection. Prolonged or repeated exposure to these hazards can increase the risk of developing acute or chronic health conditions, such as respiratory diseases, skin disorders, neurological damage, or cancer.
Employers have a legal and ethical responsibility to minimize occupational exposures through the implementation of appropriate control measures, including engineering controls, administrative controls, personal protective equipment, and training programs. Regular monitoring and surveillance of workers' health can also help identify and prevent potential health hazards in the workplace.
Eye protective devices are specialized equipment designed to protect the eyes from various hazards and injuries. They include items such as safety glasses, goggles, face shields, welding helmets, and full-face respirators. These devices are engineered to provide a barrier between the eyes and potential dangers like chemical splashes, impact particles, radiation, and other environmental hazards.
Safety glasses are designed to protect against flying debris, dust, and other airborne particles. They typically have side shields to prevent objects from entering the eye from the sides. Goggles offer a higher level of protection than safety glasses as they form a protective seal around the eyes, preventing liquids and fine particles from reaching the eyes.
Face shields and welding helmets are used in industrial settings to protect against radiation, sparks, and molten metal during welding or cutting operations. Full-face respirators are used in environments with harmful airborne particles or gases, providing protection for both the eyes and the respiratory system.
It is essential to choose the appropriate eye protective device based on the specific hazard present to ensure adequate protection.
Noise-induced hearing loss (NIHL) is a type of sensorineural hearing loss that occurs due to exposure to harmful levels of noise. The damage can be caused by a one-time exposure to an extremely loud sound or by continuous exposure to lower level sounds over time. NIHL can affect people of all ages and can cause permanent damage to the hair cells in the cochlea, leading to hearing loss, tinnitus (ringing in the ears), and difficulty understanding speech in noisy environments. Prevention measures include avoiding excessive noise exposure, wearing hearing protection, and taking regular breaks from noisy activities.
