The National Institute for Occupational Safety and Health has the remit that is clear from its name. It makes sure that people are safe in their work environment and draws up regulations to keep it that way.
Both OSHA and NIOSH were created by the Occupational Safety and Health Act of 1970.
The purpose of NIOSH (National Institute for Occupational Safety and Health) is to conduct research and provide recommendations to prevent work-related injuries, illnesses, and fatalities. NIOSH also offers training and educational resources to help improve occupational safety and health practices.

OSHA, NIOSH and the Occupational Safety and Health Review Commission (OSHRC) were all established by the Occupational Safety and Health Act of 1970. OSHA issues the regulations and inspects to enforce them. NIOSH researches safety and health and recommends safety and health standards. The OSHRC reviews contested OSHA citations.

The M50 gas mask is not specifically OSHA certified; rather, it is certified by the National Institute for Occupational Safety and Health (NIOSH) for respiratory protection. OSHA standards require that respirators meet NIOSH certification for workplace safety. While the M50 is widely used by military and certain civilian agencies for protection against chemical and biological agents, its certification pertains to NIOSH rather than direct OSHA endorsement.
It is a measure of the opacity of smoke. Ringlemann grid cards run from 0 - all white smoke to 5- all black smoke. See Bureau of Mines Circular ic8333, a link to it is available on the NIOSH site at: www.cdc.gov/Niosh/mining/pubs/pubreference/outputid330.htm
A NIOSH-approved respirator with organic vapor cartridges is recommended for working with polyurethane.
The National Institute for Occupational Safety and Health (NIOSH) approve respiratory equipment.
The best place to find official information about Personal Protective Equipment (PPE) required when working with ammo that contains chemical fillers is the National Institute for Occupational Safety and Health (NIOSH) website. Specifically the NIOSH website provides the Safety and Health Topics page which contains detailed information about specific safety topics and the corresponding safety standards. This page can be accessed at https://www.cdc.gov/niosh/topics/ammunition/. The PPE topic page on the NIOSH website provides a detailed list of all the protective equipment required when working with ammo that contains chemical fillers. It is important to note that the type of PPE required depends on the type of chemical filler present in the ammo. The PPE requirements are as follows: Respiratory protection Eye/face protection Hearing protection Protective clothing GlovesIn addition to providing information about the required protective equipment the NIOSH website also provides safety tips and additional resources to help ensure the safe handling of ammo containing chemical fillers. Therefore for comprehensive and up-to-date information about PPE required when working with ammo that contains chemical fillers the NIOSH website is the best source.
NIOSH, the National Institute of Occupational Safety and Health
The National Institute for Occupational Safety and Health is participating in an international effort of research groups, government agencies and industries seeking to understand the health impact of nanotechnology and how to control potential risks. NIOSH is pursuing a number of initiatives, including: • Studying the mechanisms leading to nanoparticle toxicity. • Developing and testing methods to characterize and monitor the healthrelated properties of nanomaterials. • Investigating nanoparticle exposure and ways of controlling exposure in the workplace Through strategic planning, working in partnership with others and making information widely available, NIOSH is working in parallel with the development and implementation of nanotechnology to fulfill its mission of providing national and world leadership to prevent work-related illness and injuries.
