benzene exposure limits

info@ionscience.com, Portable Gas & Leak Detectors Data used in developing the occupational estimates for benzene were collected from several sources: CAREX defines exposure to benzene as inhalation exposure at work to levels above those encountered in the general environment. If you or any other person breathes in large amounts of benzene, get the exposed person to fresh air at once. Website: www.cdc.gov/niosh For short-term exposure to high levels of benzene, the Centers for Disease Control and Prevention (CDC) recommends getting away from the source of benzene, removing any clothing that may have benzene on it, washing exposed areas with soap and water, and getting medical care as soon as possible. From basic information about cancer and its causes to in-depth information on specific cancer types – including risk factors, early detection, diagnosis, and treatment options – you’ll find it here. When inhaled or swallowed, benzene has been found to cause different types of tumors in lab animals such as rats and mice. By swallowing. Such background concentrations are incorporated in the BEI value. Benzene is commonly found in air in both urban and rural areas, but the levels are usually very low. A series of steps were taken to assign exposure proportions to occupations and industries at risk of exposure to benzene. 1987;52:34460−34578. It’s also important to follow recommended screening guidelines, which can help detect certain cancers early. Limit or avoid exposure to fumes from solvents, paints, and art supplies, especially in unventilated spaces. STEL = Short-term Exposure Limit. Fire extinguishers, where provided, must be readily available. Accessed at http://monographs.iarc.fr/ENG/Monographs/vol100F/mono100F-24.pdf on October 15, 2015. Percentages were determined by consultation with existing evidence in the data sources, previously established methods from the Europe CAREX estimates and the expert judgement of CAREX occupational hygienists. These tests shall be provided without cost to you. Home » Understanding occupational exposure limits for benzene. 1987;316:1044−1050. ToxFAQs for benzene: www.atsdr.cdc.gov/toxfaqs/tf.asp?id=38&tid=14, Environmental Protection Agency (EPA) Tax ID Number: 13-1788491. The U.S. Occupational Safety and Health Administration (OSHA) sets strict limits on benzene in the workplace. Call for medical assistance or a doctor immediately. 1–3 Public health actions are needed to reduce the exposure of both workers and the general population to benzene. Find more information on this substance at. 2013. If you are exposed to benzene at a concentration at or above 0.5 ppm as an 8-hour time-weighted average, or have been exposed at or above 10 ppm in the past while employed by your current employer, your employer is required to provide a medical examination and history and laboratory tests within 60 days of the effective date of this standard and annually thereafter. Regulated area means any area where airborne concentrations of benzene exceed or can reasonably be expected to exceed, the permissible exposure limits, either the 8-hour time weighted average exposure of 1 ppm or the short-term exposure limit of 5 ppm for 15 minutes. IARC also notes that benzene exposure has been linked with acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), multiple myeloma, and non-Hodgkin lymphoma. Respirators are required for those operations in which engineering controls or work practice controls are not feasible to reduce exposure to the permissible level. Website: www.osha.gov The employer shall assure that no employee is exposed to an airborne concentration of benzene in excess of 5 ppm as averaged over any 15 min period. By skin contact. Dermal: Eye contact shall be prevented and skin contact with liquid benzene shall be limited. The total number of workers in each identified occupation and industry intersection was obtained from Statistics Canada 2006 census data. There is much less evidence linking benzene to any other type of cancer. IARC classifies benzene as “carcinogenic to humans,” based on sufficient evidence that benzene causes acute myeloid leukemia (AML). Biological Exposure Index (BEI): Determinant: S-phenylmercapturic acid in urine; Sampling Time: end of shift; BEI: 25 ug/g creatinine. However, where employers can document that benzene is present in the workplace less than 30 days a year, respirators may be used in lieu of engineering controls. It evaporates quickly when exposed to air. Benzene in drinking water: http://water.epa.gov/drink/contaminants/basicinformation/benzene.cfm, National Institute for Occupational Safety and Health (NIOSH), Toll-free number: 1-800-232-4636 (1-800-CDC-INFO) Stay away from cigarette smoke. CAREX uses available workplace exposure measurements in the CWED to create exposure level categories by industry and occupation. Benzene is also used to make some types of lubricants, dyes, detergents, drugs, and pesticides. B. Together, we’re making a difference – and you can, too.
