MODULE #1 (Introduction to Confined Space Rescue) - (ANSWER)
What is the percentage of fatalities of confined space rescue that would be the
rescuers? - (ANSWER)more than 60% of confined space fatalities are rescuers.
Confined space - (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 - (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
, 2
- Hazardous Atmosphere, Internal Configuration, Serious or safety health hazard
and Engulfment.
Hazardous Atmosphere - (ANSWER)May expose employees to risk of death,
incapacitation, impairment, injury or acute illness.
Oxygen Content - (ANSWER)Atmospheric oxygen concentration should be
between 19.5% and 23.5%
Oxygen Deficient - (ANSWER)Oxygen levels below 19.5%
Oxygen Enriched - (ANSWER)Oxygen levels above 23.5%
Flammable Gases, Vapors and /or Mists - (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? - (ANSWER)90%
Engulfment - (ANSWER)When a liquid or finely divided flowable solid substance
traps or surrounds a person.
, 3
- 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 - (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) - (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 - (ANSWER)Attendant, Authorized
Entrant and Entry Supervisor
Attendant - (ANSWER)An individual stationed outside one or more permit
required spaces who monitors authorized entrants and performs all duties
assigned
Authorized Entrant - (ANSWER)An employee who is authorized by the employer
to enter a permit required space.
, 4
Entry Supervisor - (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 - (ANSWER)-
A rescue team can be formed internally (on-site rescue team)
- Externally (Private contract or public emergency service)
Internal Rescue Teams - (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) - (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 - (ANSWER)There are 3 jurisdictional
approaches to emergency response
- Self Sufficient Method
- Community Dependent Method
