Which SSPC guide covers containment classes for removing lead-containing paint?

Answer: SSPC-Guide 6

SSPC-Guide 6 sets containment system classes for paint removal operations.

Why are lead abatement containments often kept under negative pressure?

Answer: To keep dust from escaping the enclosure

Negative pressure pulls air inward so leaks do not release lead dust outside.

Answer: Washing hands and face before eating, drinking, or smoking

Blowing dust off clothing puts lead back into the breathing zone.
