TEEX Confined Space Rescue Levels 1&2
(NFPA 1006) Questions And Answers 100%
Correct
MODULE #1 (Introduction to Confined Space Rescue)
What is the percentage of fatalities of confined space rescue that would be the rescuers?
more than 60% of confined space fatalities are rescuers.
Confined space - 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 (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
, TEEX Confined Space Rescue Levels 1&2
(NFPA 1006) Questions And Answers 100%
Correct
- Contains any other recognized serious safety or health hazard
- Hazardous Atmosphere, Internal Configuration, Serious or safety health hazard and
Engulfment.
Hazardous Atmosphere May expose employees to risk of death, incapacitation,
impairment, injury or acute illness.
Oxygen Content Atmospheric oxygen concentration should be between 19.5% and 23.5%
Oxygen Deficient Oxygen levels below 19.5%
Oxygen Enriched Oxygen levels above 23.5%
Flammable Gases, Vapors and /or Mists 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

(NFPA 1006) Questions And Answers 100%
Correct
What is the percentage of injuries and deaths in confined space that are the result of a hazardous
atmosphere? 90%
Engulfment 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 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) 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 Attendant, Authorized Entrant and Entry
Supervisor
Attendant An individual stationed outside one or more permit required spaces who
monitors authorized entrants and performs all duties assigned
Authorized Entrant An employee who is authorized by the employer to enter a permit
required space.
Entry Supervisor 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 - A rescue team can
be formed internally (on-site rescue team)
- Externally (Private contract or public emergency service)
