OSHA's substance-specific standards specify which elements?

OSHA's substance-specific standards specify which elements?

• A. Emergency evacuation routes
• B. Applicable permissible exposure limits
• C. Noise measurement procedures
• D. Employee payroll procedures

Answer: (B)

OSHA’s substance-specific standards center on setting the levels of exposure workers may safely experience for particular hazards. The key element these standards specify is the permissible exposure limits (PELs), which define the maximum airborne concentration allowed for a worker over a defined period (such as an 8-hour time-weighted average or a shorter exposure limit for brief peaks). These limits guide how exposures are measured, when controls must be put in place, and when medical surveillance or monitoring is required. Other listed items don’t fit the substance-specific standard focus: emergency evacuation routes belong to general safety planning, noise measurement procedures are governed by separate noise standards, and payroll procedures have no relation to hazard exposure or control.
