Question 0

1.2 what is a permit required confined space and who is it designated by?

Answer 0

If a confined space poses a danger to anyone that enters it, it is designated a
Permit Required Confined Space (permit space). A Permit Space is any
confined space that has one or more of the following potential problems:
• Contains or has the potential to contain a hazardous atmosphere.
• Contains material that could potentially engulf a person.
• Is shaped in a way that a person could be caught or asphyxiated by inwardly
tapering walls, or floors that slope downward, tapering into a smaller cross
section.
• Contains any recognized serious health or safety hazard.

A permit space is designated by the owner of the space, who issues the permit.

Question 2

2.1 Atmospheric hazards can be of three types, what are they?

Answer 2

ATE

A Asphyxiant
T Toxic
E Explosive

Question 3

2.1 Atmospheric Hazard

Due to the potential for life threatening atmosphere, all members entering any
confined space must be breathing air from their SCBA at all times, until the
atmosphere is verified safe !
How is this determined?

Answer 3

2.1.1
The only safe way to detect a lack of oxygen is through
the use of an oxygen meter carried by Rescue Companies and Haz Mat.

Question 4

2.1.2 which atmosphere is the hardest to evaluate?

Answer 4

2.1.2 Toxic atmospheres are more difficult to evaluate and operate in than are asphyiant
atmospheres.

Question 5

3.1 Before a member is permitted to enter a confined space to perform a rescue, that member
must, by law, be provided with sufficient information, training and protection to allow
him to conduct the rescue in as safe a manner as possible.
3.1.1 As a bare minimum, the rescuer who is entering a confined space must know:

Answer 5

CHEAP- C-Communication H-Hazard E-Escape A-Aid/CFR-D/First aid P-Protective equipment

Question 6

Once a tower ladder or aerial ladder have been positioned

To use as a high point what should be done in regards to safety?

Answer 6

4.4

Question 7

5.6 note

Personnel from EMS to all confined space rescue incidents.

Question 8

What must be set up prior to members entering a confined space?

Answer 8

Confined Space Check List
Means of hauling members out of space (retrieval system) must be set up before
member enters space.

Question 9

Confined Space Check list
There are acceptable levels of atmospheric hazards in a confined
that members can enter, choose the incorrect statement.

A. Oxygen Concentration between 19.5% and 23.5%.
B. Flammable Range - Not over 10% of LEL.
C. Toxicity - over 35 PPM of Carbon Monoxide
D. Not over 10 PPM of Hydrogen Sulfide

Answer 9

C. Is incorrect it should read

CO not over 35ppm
