CPR Water Loss Classification & Category Standards 3

Question 1

If Category 2 water contacts porous materials and is not promptly extracted, after approximately 24–48 hours the loss should be treated as:

Accepted Answer

Category 3 due to microbial amplification

Answer

Prolonged exposure allows microbial growth in Category 2 affected materials, requiring reclassification and treatment as Category 3 per IICRC S500.

Question 2

An aquarium that overflows and saturates the carpet and subfloor of an entire room would be classified as:

Accepted Answer

Category 1, Class 2

Answer

Aquarium water is clean (Category 1) and an entire room affected with absorption into subfloor materials represents a Class 2 loss.

Question 3

When a restorer arrives on site and identifies Category 3 water, the immediate priority should be:

Accepted Answer

Document the category, restrict access, and use appropriate PPE before beginning remediation

Answer

Category 3 is a health hazard; the restorer must document conditions, restrict occupant access, and don appropriate PPE before remediation work begins.

Question 4

Under the IICRC S500, which combination correctly describes a sewage backup that has saturated hardwood floors throughout the affected area?

Accepted Answer

Category 3, Class 4

Answer

Sewage is Category 3, and hardwood flooring with dense substrate saturation requiring specialty drying is Class 4.

Question 5

A toilet overflow caused by a blocked drain (containing urine but no feces) that affects only the vinyl tile floor of a bathroom would most likely be classified as:

Accepted Answer

Category 2, Class 1

Answer

Toilet overflows with urine are Category 2 (grey water), and a small area of low-porosity vinyl tile with minimal absorption is a Class 1 loss.
