Certified Hyperbaric Technologist Test CHT Fire Safety and Oxygen Hazards in Hyperbaric Environments 2

Question 1

Which type of fire suppression system is most commonly installed in multiplace hyperbaric chambers?

Accepted Answer

Water deluge system

Answer

Water deluge systems are preferred in multiplace chambers because they rapidly cool and suppress fires without creating toxic atmospheres harmful to patients and staff inside.

Question 2

What rating must electrical equipment used inside a hyperbaric chamber carry?

Accepted Answer

Intrinsically safe or explosion-proof rated

Answer

Equipment used inside hyperbaric chambers must be intrinsically safe or explosion-proof to prevent sparks or arcing that could ignite the oxygen-enriched atmosphere.

Question 3

Which of the following personal care products is specifically prohibited before hyperbaric treatment?

Accepted Answer

Hair spray and petroleum-based lotions

Answer

Hair spray and petroleum-based lotions are flammable and prohibited because they increase fire risk in the oxygen-enriched chamber environment.

Question 4

Which factor presents the GREATEST increase in fire risk within a hyperbaric chamber?

Accepted Answer

Elevated oxygen partial pressure

Answer

Elevated oxygen partial pressure is the primary fire risk factor because it dramatically lowers the ignition threshold and accelerates combustion of ordinary materials.

Question 5

The 'hot work permit' protocol in hyperbaric facilities is required before:

Accepted Answer

Welding, cutting, or grinding near oxygen systems

Answer

Hot work permits are required before welding, cutting, or grinding near hyperbaric oxygen systems because these activities generate sparks near flammable oxygen-rich environments.
