QUESTIONS AND ANSWERS SET A+
✔✔Describe when abated surfaces should be painted or otherwise sealed - ✔✔After
final cleanup but before clearance
✔✔Describe the proper order for final cleanup - ✔✔-HEPA Vac
-Wash
-Rinse
-Start with the rooms furthest away from the front door and from the top down

-Detergent
-HEPA vac
✔✔The correct location of lead warning signs - ✔✔at entrances
(# of signs depends on if you are doing a whole building)

-Power washing within containment
-Machine sanding/grinding without HEPA
-Abrasive blasting
, -Certain paint stripping
-Removing a painted component
✔✔Why are torch guns or heat guns above 1100F prohibited? - ✔✔-Lead has a low
melting point

✔✔Describe recommended chemical paint removal methods - ✔✔-Use paint stripper
that does not contain methylene chloride
-Neutralize surface after using the paint stripper
✔✔When is personal protective clothing and equipment are required? - ✔✔-Required
when air lead levels are above PEL
-Recommended when below PEL
