TEEX Confined Space Rescue Levels 1&2
(NFPA 1006) UPDATED Exam Questions
and CORRECT Answers
MODULE #1 (Introduction to Confined Space Rescue) - CORRECT ANSWER -
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
, Self Sufficient Method - CORRECT ANSWER - -The responding agency is responsible
for everything when a confined space incident occurs in their jurisdiction.
- Most expensive approach
- Onsite rescue team
Community Dependent Method - CORRECT ANSWER - - Seek out community agency
who have rescue training and experience
- Create a resource contact list is an emergency arises
- Fire department, Police and Emergency rescue teams
Regional Method - CORRECT ANSWER - - Most Cost effective
- Spread across several jurisdictions
- More detailed system of accountability
- Disaster readiness, Massive response and Least Expensive
Operational Readiness Trifecta - CORRECT ANSWER - - Personnel: Rescuers that should
be medically and psychologically evaluated for confined space rescue
- Training: Establishes and maintains knowledge with skill proficiency
- Equipment: Right equipment for safe and effective rescue operations
NFPA 1006 - CORRECT ANSWER - Standard for Technical Rescuer Professional
Qualifications: Minimum JPR's for personnel that perform technical rescue operations.
NFPA 1500 - CORRECT ANSWER - Standard on Fire Department Occupational Safety,
Health, and Wellness Program
NFPA 1561 - CORRECT ANSWER - Standard on Emergency Services Incident
Management System and Command Safety
