TEEX Confined Space Rescue Levels 1&2 (NFPA 1006)
Exam Questions and Answers
MODULE #1 (Introduction to Confined Space Rescue) - Answer
What is the percentage of fatalities of confined space rescue that would be the
rescuers? - Answermore 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
- Hazardous Atmosphere, Internal Configuration, Serious or safety health hazard and
Engulfment.
Hazardous Atmosphere - AnswerMay expose employees to risk of death,
incapacitation, impairment, injury or acute illness.
Oxygen Content - AnswerAtmospheric oxygen concentration should be between 19.5%
and 23.5%
Oxygen Deficient - AnswerOxygen levels below 19.5%
Oxygen Enriched - AnswerOxygen levels above 23.5%
Flammable Gases, Vapors and /or Mists - AnswerThe 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? - Answer90%
Engulfment - AnswerWhen 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 - AnswerAn 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) - AnswerAny 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 - AnswerAttendant, Authorized Entrant and
Entry Supervisor
Attendant - AnswerAn individual stationed outside one or more permit required spaces
who monitors authorized entrants and performs all duties assigned
Authorized Entrant - AnswerAn employee who is authorized by the employer to enter a
permit required space.
Entry Supervisor - AnswerThe 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 - AnswerFederal 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 - AnswerThere are 3 jurisdictional approaches to
emergency response
- Self Sufficient Method
- Community Dependent Method
, - Regional Method
Self Sufficient Method - 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 - 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 - Answer- Most Cost effective
- Spread across several jurisdictions
- More detailed system of accountability
- Disaster readiness, Massive response and Least Expensive
Operational Readiness Trifecta - 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 - AnswerStandard for Technical Rescuer Professional Qualifications:
Minimum JPR's for personnel that perform technical rescue operations.
NFPA 1500 - AnswerStandard on Fire Department Occupational Safety, Health, and
Wellness Program
NFPA 1561 - AnswerStandard on Emergency Services Incident Management System
and Command Safety
NFPA 1584 - AnswerStandard on the Rehabilitation Process for Members During
Emergency Operations and Training Exercises
NFPA 1670 - AnswerStandard on Operations and Training for Technical Search and
Rescue Incidents
NFPA 1951 - AnswerStandard on Protective Ensembles for Technical Rescue
Incidents: Helmets and Boots
NFPA 1983 - AnswerStandard on Life Safety Rope and Equipment for Emergency
Services: Identifies requirements for life safety rope and equipment used in rescue
emergency operations
