(4 RC) - The Health Hazard Evaluation Program received a confidential employee request for the National Institute for Occupational Safety and Health to conduct a health hazard evaluation at a hospital. The request cited concerns about exposure of hospital employees to a sporicidal product that contains hydrogen peroxide, peracetic acid, and acetic acid, and described symptoms experienced by employees. Employee symptoms noted in the health hazard evaluation request included burning eyes, nose, and throat; runny nose; cough; headache; dizziness; nausea; nose bleeds; asthma exacerbation; skin burns; and rashes… (CDC HHE, Sep 2018)
(4 RC) - The former Delfasco Forge facility is in Grand Prairie, Dallas County, Texas. The facility operated as a munitions manufacturing and forging facility from 1980 to 1998. Former facility operations used chlorinated solvents containing trichloroethylene (TCE) and other chemicals to degrease metal. These operations contaminated on-site soil and groundwater. The groundwater contamination has spread to the adjacent residential area where an estimated 157 occupied homes… (CDC ATSDR, Apr 2024)
(1 RC) - Illicit drug operations present multiple exposure pathways. Responders may encounter packaged powder, loose powder, pill mills, aqueous liquids and hardened (described as concrete-like) fentanyl analogs. Bulk fentanyl is mixed with other narcotics because it is a cheap filler material. Makeshift laboratories are found in apartments, houses, garages and storage facilities… (EPA, May 2018)
(1 RC) - Increased engineered nanomaterial production, combined with widespread formulation and incorporation into nanomaterial enabled products, has increased the likelihood of occupational exposure. A key component in managing the occupational risk is exposure assessment… (NIOSH, July 2022)
(2 RC) - Diacetyl and 2,3-pentanedione have a long history as components of food, suggesting that exposures can occur in diverse work-places. They occur as natural products in many foods. Diacetyl imparts the flavor and aroma of butter to many common foods and drinks including butter, cheese, yogurt, beer, and wine… (NIOSH Standard, Oct 2016)
(3 RC) - The goal of this chapter is first to present a numerical estimate of the risk of developing respiratory disease due to occupational exposure to diacetyl using standard epidemiological methods. This estimate is based on statistical models that describe the relationship between exposure to diacetyl and the development of impaired lung function in a known population of exposed employees… (NIOSH Standard, Oct 2016)
(4 RC) - Work practices are procedures followed by employers and employees to control hazards in the workplace. The use of good work practices, incorporated into the facility’s standard operating procedures, can help reduce exposures to diacetyl, 2,3-pentanedione, and other flavoring compounds while at the same time maximizing efficiency and product quality… (NIOSH Standard, Oct 2016)
(.50 RC) - Employers should develop and implement comprehensive occupational safety and health programs to prevent occupational injuries, illnesses, and deaths. To be successful, safety and health programs should be developed and implemented as part of an employers management system, with strong management commitment, employee involvement, and occupational safety and health expertise. A safety and health program designed to protect employees from the adverse effects of exposure to diacetyl, 2,3-pentanedione, and other flavoring compounds… (NIOSH Standard, Oct 2016)
(2 RC) - NIOSH received a request for help in assessing worker exposure to isocyanates during spray painting of automobiles. An autobody repair shop whose other concerns for worker exposure included solvents, total dusts, noise, carbon monoxide, and metals. An initial survey was conducted in September 1995 and an interim report was issued in January 1996. To assess effects of seasonal variation… (NIOSH, June 1995)
(4 RC) - This report deals with safe water supply extending from source to consumer, including plumbed-in devices, domestic and building environments, and water supplied in bottles or packages. The different ways in which drinking-water may be used in the home are considered, and specific concerns in higher-risk settings and populations at increased risk are addressed. … (WHO, 2003)
