Is the statement true or false: Personal protective equipment must be used if the CAS number exceeds the PEL for an eight-hour period?

Is the statement true or false: Personal protective equipment must be used if the CAS number exceeds the PEL for an eight-hour period?

• A. True
• B. False
• C. Depends on the industry
• D. Only if specified

Answer: (B)

The statement is false. Personal protective equipment (PPE) should be used not merely based on whether the chemical's CAS number exceeds the permissible exposure limit (PEL) for an eight-hour period, but rather, the use of PPE is dictated by various factors including the nature of the hazard, the level of exposure, and specific workplace protocols. While PELs are important benchmarks for exposure limits over time, situational assessments must also consider other factors such as the type of chemical, its volatility, and the work environment to determine the appropriate safety measures. In cases where PELs might exceed, it would be necessary to employ PPE, but this is not solely contingent on the numerical threshold. Adequate training and risk assessments should be part of a comprehensive safety plan to ensure protection from occupational hazards.
