A+ GRADE VERIFIED ANSWERS
MODULE #1 (Introduction to Confined Space Rescue)
What is the percentage of fatalities of confined space
rescue that would be the rescuers? Correct Answer more
than 60% of confined space fatalities are rescuers.
Confined space Correct Answer - It is large enough and
configured so that an employee can bodily enter and
perform assigned work
- It has limited or restricted means of entry or exit. (Ex:
tanks, vessels, storage bins, hoppers and pits.)
- It is not designed for continuous employee occupancy
Permit Required Confined Space Correct Answer (also
called a permit space)
- Contains a hazardous atmosphere
- Contains a material that has the potential to engulf an
entrapment
- Contains internal configurations with the ability to trap or
asphyxiate an entrant by inwardly converging walls or
downward sloping floors that taper into smaller cross
section
,- Contains any other recognized serious safety or health
hazard
- Hazardous Atmosphere, Internal Configuration, Serious
or safety health hazard and Engulfment.
Hazardous Atmosphere Correct Answer May expose
employees to risk of death, incapacitation, impairment,
injury or acute illness.
Oxygen Content Correct Answer Atmospheric oxygen
concentration should be between 19.5% and 23.5%
Oxygen Deficient Correct Answer Oxygen levels below
19.5%
Oxygen Enriched Correct Answer Oxygen levels above
23.5%
Flammable Gases, Vapors and /or Mists Correct Answer
The concentration of any flammable gas vapor or mist
must be below 10% of its Lower flammability Limit (LFL)
- The LFL is the lowest concentration that a flammable
mixture can be ignited when it comes into contact with an
ignition source at a sufficient temperature
What is the percentage of injuries and deaths in confined
space that are the result of a hazardous atmosphere?
Correct Answer 90%
Engulfment Correct Answer When a liquid or finely divided
flowable solid substance traps or surrounds a person.
,- The substance can fill or plug the respiratory system
- The substance can exert enough force on the body to
strangulate, constrict or crush the person.
Bridging Correct Answer An example of engulfment
- Material that is loaded into a vessel that can adhere to
the sides of the vessel or clump together because of the
temperature or environment. When the material is
unloaded from the bottom it can create avoid space that
can not be seen and can collapse at any point. Anyone
who steps on top of the material can fall below the bridged
material and become trapped.
Immediately Dangerous to Life and Health (IDLH) Correct
Answer Any condition that would pose an immediate or
delayed threat to life, cause irreversible adverse health
effects, or interfere with an individuals ability to escape
unaided from a hazardous environment.
Individual Roles in Confined Space Entry Correct Answer
Attendant, Authorized Entrant and Entry Supervisor
Attendant Correct Answer An individual stationed outside
one or more permit required spaces who monitors
authorized entrants and performs all duties assigned
Authorized Entrant Correct Answer An employee who is
authorized by the employer to enter a permit required
space.
, Entry Supervisor Correct Answer The person responsible
for determining if acceptable entry conditions are present
at a permit space where entry is planned, for authorizing
entry and overseeing entry operations and for terminating
entry as required.
Requirements for Rescue and Emergency Services in
Permit Spaces Correct Answer - A rescue team can be
formed internally (on-site rescue team)
- Externally (Private contract or public emergency service)
Internal Rescue Teams Correct Answer Federal
regulations require employees to:
- Provide appropriate PPE
- Train employees to perform rescue duties, Basic First aid
and CPR
- AT LEAST ONE MEMBER MUST BE CERIFIED IN CPR
- Practice permit required space rescues once a year
Safety Data Sheet (SDS) Correct Answer - Sheet that
provides information on the safe use of and hazards of
chemicals, as well as emergency steps to take in the
event chemicals are splashed, sprayed, or ingested
- If an injury occurs an SDS must be available
Approaches to Operational Readiness Correct Answer
There are 3 jurisdictional approaches to emergency
response
- Self Sufficient Method
- Community Dependent Method
- Regional Method
