HMIS retired the yellow reactivity bar due to changes in how NFPA's equivalent, renamed 'Instability', that resulted in it no longer being suitable for HMIS. HMIS III also adopted the OSHA flammability criteria, as defined by Standard 1910.106. [15] The orange 'Physical hazard' bar is defined through OSHA's physical hazard [2]
UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. [1] The standard determines the material's tendency to either extinguish or spread the flame once the specimen has been ignited.
The Bureau of Labor Standards of the Department of Labor has worked on some work safety issues since its creation in 1934. [4] Economic boom and associated labor turnover during World War II worsened work safety in nearly all areas of the United States economy, but after 1945 accidents again declined as long-term forces reasserted themselves.

Division 4.1: Flammable Solid . Flammable solids are any of the following four types of materials: Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 Table or ...
Extremely flammable gas H221: Flammable gas H222: Extremely flammable material H223: Flammable material H224: Extremely flammable liquid and vapour H225: Highly flammable liquid and vapour H226: Flammable liquid and vapour H227: Combustible liquid H228: Flammable solid H229: Pressurized container: may burst if heated H230
In addition to GHS, flammability classifications are incorporated into various systems designed for communicating physical and health hazards in workplaces; such as American Coatings Association's Hazardous Materials Identification System (HMIS) and Lab Safety Supply's Hazardous Material Identification Guide (HMIG).

Process Safety Management of Highly Hazardous Chemicals is a regulation promulgated by the U.S. Occupational Safety and Health Administration (OSHA). [1] It defines and regulates a process safety management (PSM) program for plants using, storing, manufacturing, handling or carrying out on-site movement of hazardous materials above defined amount thresholds.
The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.
