SafetyCâu 679 / 700
On a lead-in-construction job, the airborne action level is about 30 micrograms per cubic meter and the permissible exposure limit is about 50 micrograms per cubic meter (8-hour average). What is the PRIMARY significance of exposure reaching the action level?
a.Work must stop entirely until lead is removed
b.It triggers ongoing duties such as periodic exposure monitoring and starting a medical surveillance program for exposed workers
c.Respirators alone become sufficient with no other measures
d.It only requires posting a warning sign at the property line
Giải thích
Correct: reaching the lead action level (about 30 micrograms per cubic meter) triggers continuing obligations, notably periodic exposure monitoring and enrolling exposed workers in medical surveillance (including blood-lead testing). Work does not automatically stop. Respirators are only one part of a required program that also includes controls and hygiene facilities. A property-line sign is not the defining requirement of the action level.
