SafetyCâu 576 / 700
Before demolishing interior finishes in a commercial building from the 1970s, what is the BEST first step regarding possible asbestos?
a.Start demolition and stop if fibers are seen
b.Have suspect materials surveyed and tested by a qualified person before disturbing them
c.Wet the materials and remove them like any debris
d.Assume no asbestos because the building looks clean
Giải thích
Older buildings may contain asbestos in flooring, mastic, plaster, insulation, and other finishes, so a survey and sampling by a qualified person must occur before disturbance, with proper abatement if asbestos is present. Option a exposes workers before testing. Option c treats regulated material as ordinary debris. Option d relies on appearance, which cannot reveal asbestos. Testing first protects workers and ensures lawful, licensed handling.
