Which component is established by OSHA standards as enforceable in IH practice?

• A. Employee lunch break length.
• B. Exposure limits.
• C. Personal salary guidelines.
• D. Office temperature.

Answer: (B)

Exposure limits are the enforceable safety standards OSHA establishes to protect workers from hazardous substances in the air. These limits, such as permissible exposure limits (PEL) and short-term exposure limits (STEL), are legally binding and require employers to keep worker exposures below specified concentrations over defined time periods. The whole purpose is to ensure a measurable, enforceable standard that can be monitored, recorded, and enforced through inspections and penalties if violated.

Other options aren’t enforceable health‑and‑safety limits set by OSHA. Meal breaks, salary guidelines, and typical office temperature are governed by different policies or considerations and do not constitute workplace exposure standards that OSHA can enforce for protecting workers’ health.
