What is the role of OSH regulatory standards (OSHA) in industrial hygiene practice?

• A. OSHA standards provide general, non-enforceable recommendations for workplaces.
• B. They regulate only exposure limits.
• C. They establish enforceable requirements for worker safety and health programs, exposure limits, training, recordkeeping, and hazard communication.
• D. They focus exclusively on hazard communication.

Answer: (C)

OSHA standards establish enforceable requirements that define what employers must do to protect workers’ safety and health. They go beyond mere guidance and set concrete obligations across multiple areas: exposure limits for hazardous substances, programs and procedures to control risks, training and education for employees, recordkeeping of exposure and illness data, and hazard communication so workers understand hazards and protective measures. In industrial hygiene practice, these standards guide how exposures are assessed, how controls are selected and implemented (preferring engineering controls first, then administrative controls and PPE), and how compliance is documented through required records and training. They are a comprehensive framework that shapes everyday workplace protections, not just a single narrow focus.
