What must a restorer do when Category 1 water damage is discovered to also have pre-existing mold present?
Answer: Treat the mold area under mold remediation protocols regardless of the water category
Pre-existing mold discovered during a Category 1 job must be addressed under appropriate mold remediation protocols, which operate independently of the water damage category.
What is the recommended PPE for entering a Category 2 affected area during active mitigation?
Answer: Gloves, safety glasses or goggles, and waterproof boots at minimum
Category 2 work requires at minimum non-porous gloves, eye protection, and waterproof boots to prevent skin and eye exposure to biologically contaminated water.
How does storm surge floodwater differ from rainwater that enters a building in terms of IICRC category?
Answer: Storm surge is Category 3 due to seawater and contaminants; rainwater is Category 1 initially
Storm surge from coastal flooding carries seawater, sewage, chemicals, and debris making it Category 3, while rainwater entering through a roof is initially considered Category 1.
What action is required when a technician discovers asbestos-containing materials (ACM) while performing a flood cut?
Answer: Stop work immediately, secure the area, and notify the project manager and insurance company
Discovery of suspected ACM requires immediate work stoppage, area containment, and notification of the relevant parties, as ACM removal requires licensed abatement contractors under EPA law.
