Impairment Control and Fire Watch Procedures Flashcards

Under NFPA 25, if a system will be out of service more than 10 hours in a 24-hour period, what action is typically required?

Answer: Evacuate the building or provide an approved fire watch

Extended impairments over 10 hours require evacuation or a fire watch unless otherwise approved.

Which activity should be prohibited in an area where sprinkler protection is impaired?

Answer: Hot work such as welding or cutting

Hot work greatly increases ignition risk and should be stopped when protection is impaired.

During a fire watch patrol, a guard discovers a fire. What is the first priority?

Answer: Notify the fire department and alert occupants

Immediate notification of the fire department and occupants saves lives and limits loss.

Why should an impairment be limited to the smallest possible area of the system?

Answer: To keep as much of the building protected as possible

Isolating only the needed section keeps protection active elsewhere.

What equipment should a fire watch person typically carry or have immediate access to?

Answer: A means to call the fire department and a portable fire extinguisher

Fire watch personnel need communication and basic extinguishing capability.

Which document records each fire watch patrol, including times and areas checked?

Answer: Fire watch log

A fire watch log documents patrols and is subject to fire department review.

When an impairment is identified, why should the alarm monitoring company be notified?

Answer: So signals from the impaired system are handled correctly and not misinterpreted

The central station must know about impairments to properly process trouble or supervisory signals.
