21 workers were randomly selected (from a SEG of 200 workers)
and their exposure was monitored for exposure to Toluene. The
results were reported as (exposure level/PEL) in the data sheet on
the next slide.
a. What is the PEL in the Singapore WSH General Provisions
Regulations?
b. What is the CV based on the NIOSH Manual of Analytical
Method?
c. What is the number of workers whose exposure levels were
clearly acceptable and those clearly unacceptable?
