Title X of the Housing and Community Development Act requires sellers and landlords to disclose known lead paint hazards in pre-1978 housing.

Question 3

When measuring steady-state combustion efficiency, a flue gas analyzer measures CO in the flue at 200 ppm air-free. Per BPI standards, what does this indicate?

Accepted Answer

The appliance is approaching the 400 ppm red-tag limit; flag for service

Answer

200 ppm air-free is below the 400 ppm BPI red-tag threshold but indicates imperfect combustion; the appliance should be flagged for service.

Question 4

Which insulation material, commonly used in older attics, is a known health hazard that requires special handling and EPA regulations?

Accepted Answer

Urea-formaldehyde foam insulation (UFFI)

Answer

Urea-formaldehyde foam insulation was banned for residential use in 1982 by the CPSC due to formaldehyde off-gassing health concerns.

Question 5

What is the purpose of a 'draft test' performed using a smoke pencil at a draft hood?

Accepted Answer

To verify the direction of air movement — into or out of the draft hood opening
