5-3: GFE Evolutions Flashcards
How can atmospheric hazards be introduced into confined spaces?
chemicals, sludge, sewage
Each SDS includes sections for what information?
known or suspected hazards in a space, how to a combat a fire involving it, first aid
When should you perform a drop test?
Prior to entering a space
What are the three components of the fire triangle?
Fuel, O2, Ignition
Where should exhaust fans or blowers be located so exhaust ducts will be under negative pressure?
In duct outlet on weather deck
What is the purpose of the three required drop tests?
To check for false/consistent readings
What is the predominant gas present in affected spaces for all classes of fire?
CO
What is the goal of post-fire ventilation?
Replace 95% of the smoke-laden air with fresh air
What is the purpose of explosion-proof blowers?
Exhaust air from a space containing greater than 10% LEL
When is extensive post-fire atmospheric testing required?
When a large fire damages the ventilation system or extensive partially burned material remains
When should the closed compartment and void/tank opening request form be completed?
At least 24 hrs or sufficient time to properly plan and conduct GFE services
What topics does the safety brief cover?
- contents that can introduce flammable, toxic, O2 depleting, O2 enriching 2. configuration that can inhibit ventilation and escape 3. Type of operations to be conducted which could produce toxicants/flammables 4. Fixed equipment within space (pipes/pressurized lines) 5. presence of slippery surfaces, poor lighting, HAZMAT, 6. Contents in adjacent spaces 7. Hazards can be created by work being done in the space like welding and painting
What information is contained in the closed compartment and void/tank opening request form?
Reason for entry, personnel entering the space, tag-outs requires
What does training of personnel participating in confined space rescue include?
Responsibilities of each person, proper use of equipment, training/drills semi-annually
What does personnel protective clothing for emergency rescue operations consist of?
SAR/SCBA, safety harnesses, comms, hoisting equipment, gloves/boots/helmets/coveralls
