TB Confined Space Flashcards
2 Main categories of confined spaces are Atmospheric Hazards & Physical Hazards. Atmospheric account for 65% of all confined space deaths. Name the 3 types of Atmospheric
“ATE” Asphyxiate, Toxic, Explosive
How can you detect a lack of oxygen in the atmosphere
Oxygen meter carried by Rescue & Haz Mat companies
What is harder to evaluate Asphyxiate or Toxic atmospheres
Toxic atmospheres. There are NO accurate ways to test for presence of all possible toxic materials in a field setting. Treat all confined spaces as deadly atmospheres until proven otherwise
As a bare minimum, the rescuer who is entering a confined space must know “CHEEF”
Communicate w/attendant outside, Hazards within the space, Escape route in an emergency, Equipment- how to use, & First aid/CPR
Prior to entry into a confined space 1 member should be designated SCBA control timer. When does the time get written down?
Write down time each member dons their facepiece
Each member entering a confined space must be secured to LSR using _
Can a TL be used as a high anchor point
Bowline on a bight & slippery hitch to LSR
Yes- preferred over AL. Supports at least 800 lbs compared to 250 lbs of AL. Never use either as a crane. Remove personnel from TT & shut engine off
Can CPR be performed in Confined Space
Introducing O2 into a flammable atmosphere could cause an explosion & dangerous atmosphere can be pumped into the victim. Generally, best to remove victim to a safe atmosphere ASAP
If a victim is found unconscious for an unknown reason in a confined space, how should we treat the patient
Treat as having a spinal injury
Safe Atmospheric Conditions A. O2 between _ & _% B. Flammable range NOT over _% LEL C. Toxicity of CO NOT over _ PPM D. Hydrogen sulfide NOT over _ PPM
A 19.5-23.5%
B. Not over 10% LEL
C. 35 PPM
D. 10 PPM
