What governs the labeling of hazardous materials according to OSHA?

The labeling of hazardous materials according to OSHA (Occupational Safety and Health Administration) is governed by Material Safety Data Sheets (MSDS), which are now commonly referred to as Safety Data Sheets (SDS). These sheets provide detailed information about the properties of each chemical, including hazards, handling instructions, storage recommendations, and emergency measures in case of exposure or incidents.

The guidance for labeling comes from the need for comprehensive communication about the hazards of chemicals in the workplace. OSHA's Hazard Communication Standard requires that employers make SDS available to their employees and that hazardous materials be labeled clearly, which is essential for ensuring safety and compliance in environments where such materials are handled.

The other options do relate to safety in various contexts, but they do not specifically govern the labeling of hazardous materials as defined by OSHA standards. Fire codes generally deal with fire safety regulations, health and safety regulations encompass a broader scope of worker safety, and environmental protection laws prioritize ecological impacts rather than specifically addressing material labeling within workplace settings. Hence, Safety Data Sheets are the critical documents that ensure proper labeling of hazardous materials.
