CCS Fire Prevention & Creosote Management 4

Question 1

Which component of wood smoke is primarily responsible for forming creosote deposits?

Accepted Answer

Unburned hydrocarbons, tar vapors, and moisture

Answer

Creosote forms when unburned hydrocarbons, volatile tar vapors, and water vapor cool and condense on the inner flue surfaces.

Question 2

What is the correct immediate action if a homeowner calls to report an active chimney fire?

Accepted Answer

Advise them to call 911 immediately and evacuate the home

Answer

An active chimney fire is a life-safety emergency; residents should evacuate and call 911, as the fire can spread to the structure.

Question 3

Which chimney liner material provides the best protection against high-temperature chimney fires?

Accepted Answer

UL-listed stainless steel liner rated for solid-fuel use

Answer

UL-listed stainless steel liners are tested and rated to contain chimney fires and withstand the extreme temperatures they generate.

Question 4

A sweep discovers a 1/8-inch continuous crack running the length of a clay tile liner after a chimney fire. What is the appropriate recommendation?

Accepted Answer

Reline the entire flue before resuming use of the appliance

Answer

A continuous crack in a clay tile liner compromises containment; combustion gases and future chimney fire heat can breach the liner and enter the structure.

Question 5

Why is a metal chimney cap considered a fire prevention device, not just a weather exclusion device?

Accepted Answer

The cap prevents burning embers from exiting the flue and igniting roof or nearby combustibles

Answer

A properly fitted chimney cap with spark-arrestor mesh prevents live embers from escaping the flue and landing on the roof, dry vegetation, or adjacent structures.
