Since OSHA released the revised Hazard Communication Standard (HCS) last year, there have been questions about container labeling — both on shipped containers and those used for workplace labeling.
Many employers use in-plant labeling such as the Hazardous Materials Information System (HMIS®) and the National Fire Protection Association (NFPA®) 704 Hazard Rating systems. HazCom 1994 allowed employers flexibility regarding the use of in-house labeling systems, and OSHA retained that flexibility in the revised HCS.
