Confined Space Flashcards
The percentage of casualties at confined space ops. for rescuers
60%
Name 3 ways federal regulations define a confined space
- Not designed for continuous human occupancy 2. Large enough that a person can enter and perform work 3. Has limited means for entry and escape
If a confined space poses a danger to anyone that enters it, what shall it be designated as
Permit required confined space
The percentage of confined space deaths associated with atmospheric hazards
65%
Name 3 types of atmospheric hazards at a confined space op.
- Asphyxiant 2. Toxic 3. Explosive
Atmosphere’s that are asphyxiant’s account for what percentage of all confined space deaths
50%
A permit space is designated by who
Owner of the space
Note: OSHA requires a working sign be posted
What is a safe way to detect a lack of oxygen in a confined space
Oxygen Meter
Note: This is the only safe way to detect a lack of oxygen
True or False. There is no way to accurately test for the presence of all possibly toxic materials in a field setting
True
Note: These atmospheres are more difficult to operate in then asphyxiant ones
Except in extreme circumstances, name 2 occasions when trained members can enter a confined space when conditions permit
- Members of Rescue and Squad are trained in complex confined space entry 2. Members of SSL are trained in “Line of Sight” confined space rescue
Name 6 information tasks the 1st arriving unit must perform
- Determine nature of response 2. Contact on-site personnel 3. Interview attendant/witness 4. Examine the permit 5. Review hazard info 6. Determine hazards
Name six operational tasks the 1st arriving unit must perform
- Establish a control perimeter 2. Ensure response of necessary resources 3. Contact victim without entering the space 4. Monitor atmosphere 5. Perform risk vs benefit analysis 6. Position App. for high point anchor if possible
Name an occasion when members not trained in confined space rescue should attempt rescue of a victim
Extreme circumstances
Name an occasion when members Do Not need to use an SCBA in a confined space
Atmosphere is proven non-hazardous via a continuous meter reading
Oxygen concentration between (blank) and (blank) is considered a safe atmospheric condition in a confined space
19.5% and 23.5%
Flammable Range not over (blank) % of LEL is considered a safe atmospheric condition in a confined space
10% of LEL
Carbon Monoxide not over (blank) PPM are considered a safe atmospheric condition in a confined space
35 PPM
Hydrogen Sulfide not over (blank) PPM is considered a safe atmospheric condition in a confined space
10 PPM
Each member who enters a confined space shall be secured using what
Safety line
What is the preferred apparatus to use as a high point at a confined space op.
TL
Note: Aerial May be used if no better alternative
What is the weight supporting capacity for a TL
1000 lbs (old # was 800 lbs)
What is the weight supporting capacity of an Aerial
250 lbs
What 2 safety precautions must be implemented once a TL boom or an aerial ladder is in position at a confined space
All personnel removed from the turntable AND The engine is shut off
Which EMS personnel are allowed to make entry into a confined space
Rescue Paramedics
Note: They are not trained to make “initial” entry.
