Which marking system complies with the OSHA Hazard Communication Standard?

The Hazardous Materials Information System (HMIS) is the correct choice as it is specifically designed to comply with the OSHA Hazard Communication Standard. This standard mandates that employers communicate information about hazardous chemicals to their employees. HMIS utilizes a color-coded system along with numerical ratings to indicate the health, flammability, and physical hazards of chemicals, making it an effective way to convey essential safety information in the workplace.

The intention of the HMIS is to provide a quick visual reference for the hazards associated with chemicals, thus ensuring that workers can easily identify the risks and take appropriate safety precautions. By complying with OSHA standards, it aids in promoting a safer working environment through consistent labeling and hazard communication.

Other marking systems, while useful in their own contexts, serve different purposes. For example, the National Fire Protection Association (NFPA) system focuses primarily on fire hazards, and while it is informative, it does not fully encompass the broader requirements of OSHA. The Uniform Fire Code is related to fire safety regulations rather than chemical hazard communication, and the Toxic Substances Control Act pertains to the regulation of chemical substances but is not a labeling or marking system relevant to OSHA’s specific communication standards.
