Which term describes the maximum laser exposure limit used to protect personnel?

• A. MPE
• B. PEL
• C. TLV
• D. ALARA

Answer: (A)

The maximum laser exposure limit used to protect personnel is the maximum permissible exposure (MPE). In laser safety, the MPE represents the highest level of radiant energy to which a person can be exposed without expected adverse effects, and it is defined for different wavelengths and exposure durations. This limit is used to set safe operating procedures, determine required protective measures, and design controls around laser use. Other terms differ in scope: a permissible exposure limit (PEL) is an OSHA term for general workplace exposures (not specific to lasers), a threshold limit value (TLV) is an ACGIH guideline for various hazards, and ALARA is a safety philosophy to minimize exposure as much as reasonably achievable.
