Question

Maximum value which cannot be exceeded (even once) during a normal workday

A. STEL (Short-Term Exposure Limit)
B. PEL (Permissible Exposure Limit)
C. TLV (Threshold Limit Value)
D. CEL (Ceiling Limit)

Answer 1

The CEL (Ceiling Limit) is the maximum value that cannot be exceeded during a workday, even once.

Step-by-step explanation:

The maximum value which cannot be exceeded (even once) during a normal workday is the CEL (Ceiling Limit). The CEL is the highest concentration of a substance that should not be exceeded at any time.

For example, if the CEL for a particular chemical is 5 parts per million (ppm), then no worker should be exposed to more than 5 ppm of that chemical at any point during the workday, even for a short period of time.

It is important for employers and workers to understand and follow CELs to ensure a safe working environment and to minimize the risk of health effects from workplace exposures.
