Answer

Full Containment with airlocks is required for large Condition 3 areas (over 100 sq ft) or when vulnerable populations are present.

Question 2

Which type of air sample is collected by drawing a measured volume of air through a filter or impactor to quantify airborne spore concentrations?

Accepted Answer

Volumetric air sample

Answer

Volumetric air sampling draws a specific volume of air to quantify spore concentrations per cubic meter.

Question 3

Under IICRC S520, a 'Health and Safety Plan' for a mold remediation project should include which of the following?

Accepted Answer

Site-specific hazard identification, PPE requirements, and emergency procedures

Answer

A Health and Safety Plan must address site hazards, required PPE, decontamination procedures, and emergency response.

Question 4

IICRC S520 recommends that HEPA vacuuming during mold remediation should be performed:

Accepted Answer

Before and after disturbing contaminated materials

Answer

HEPA vacuuming before disturbance reduces spore release, and after disturbance removes residual contamination.

Question 5

Which genus of mold, commonly found after water damage, is associated with potential mycotoxin production and black powdery growth on cellulose materials?
