Disposition categories for respirator medical qualifications
medically qualified without restrictions
medically qualified with restrictions
not medically qualified (MDR must sign request)
Respiratory Protection Program Terminology: Aerosols
any material dispense from a pressurized container using a gas propellant
Respiratory Protection Program Terminology: contaminant
a material that is not normally present in the atmosphere, which can be harmful to anyone who breathes it
Respiratory Protection Program Terminology: Dust
small solid particle created by breaking up the larger particles by processes such as crushing, grinding, or expulsion
Respiratory Protection Program Terminology: Fumes
small particle (<1 micrometer) formed by condensation of a volatilized solids, usually metals
Respiratory Protection Program Terminology: Gas
a material that under normal conditions of temperatures and pressure tend to occupy the entire space uniformly
Respiratory Protection Program Terminology: Mist
Finely divided liquid droplets suspended in air and generated by condensation or atomization
Respiratory Protection Program Terminology: Oxygen Deficient Atmosphere
an atmosphere with insufficient 02 to support life. Usually caused by oxidation, dilution, or displacement
must be 19.5% by volume to use an air purifying respirator
Respiratory Protection Program Terminology: Smoke
a carbon or soot particle less than .1 micrometer in size and resulting form the incomplete combustion of carbonaceous materials such as coal or oil.
Respiratory Protection Program Terminology: Vapor
gaseous stat of a substance which is normally a liquid or a solid at room temperature.
Respiratory Protection Program Terminology: Atmosphere Immediately Dangerous to Life or Death (IDLH)
the concentration of a contaminant which can produce an immediate irreversible debilitating effect on health, or which can cause death.
Common Engineering controls used for air contaminants:
Ventilation systems
exhaust
ventilation systems can be used where:
NBC/CBR shipboard environments
examples of exhaust engineering controls:
Forced Air systems (laboratory hoods in medical/dental spaces)
Damage Control Gear (Red Devil Blowers)
Gas Free Medical Surveillance and Gas Free Physical Exam Responsibilities: Commanding Officer
establish a gas free engineering program adequately staffed with personnel trained, qualified and certified to perform gas free engineering services.
Gas Free Medical Surveillance and Gas Free Physical Exam Responsibilities: Safety Officer
Ensure that the gas free engineer program is evaluated at least annually.
Gas Free Medical Surveillance and Gas Free Physical Exam Responsibilities: Medical Department Representative
Advise the Gas Free Engineer regarding medical aid in the event there is a victim in the space and continues aid once the victim is removed.
Monitor the victims use of other emergency breathing equipment and advise the GFE when replacement required
Utilize the medical matrix to perform physical exams depending on exposure
What are the three types of respirators?
air purifying, atmosphere supplied air, and SCBA
Air purifying respirators
adequate oxygen (19.5 percent by volume) must be present
may be powered or non powered.
available in half or full face pieces
What must never be used as an air purifying respirator?
surgical masks (medical/dental use only)
Military gas masks (they are used for CBRNE)
Air purifying respirators are subdivided into what?
the contaminate they protect against.
1-Particulate
2. Gas and Vapor
what are combination cartridges and canisters
combine the removal capabilities of two or more type cartridges.
what are pre filters
used to protect against an aerosol containing a volatile organic solvent.
what is an atmosphere supplying respirator
protects the user by supplying oxygen to ensure maintenance of life
specific incidences of use of atmosphere supplying respirators
used when the contaminant has no warning property
used when the contaminants concentration is too high to us an air purifying respirator.
used when an environment is Immediately Danger to Life and Health (IDLH)
two types of Atmosphere-Supplying Respirators
hose mask respirators ( face piece, tube, harness, non kinking air supply hose) being removed from the fleet
Air Line respirators and SCBAs
air line respirators can be subdivided into how many types
- Demand
- Pressure Demand
- Continuous flow.
what is a demand air line respirator
face piece, supplied air to the user which creates a negative pressure
what is a pressure demand air line respirator
face piece. maintains a continuous positive pressure within the face piece, thus preventing contaminant leakage into the face piece
what is a continuous flow air line respirators:
available with a face piece, hood, helmet, suit. continuous flow of air which maintains positive pressure within the respirator.
what is the maximum length of hose allowed from a compressor or air fitting to the respirator?
300 ft
What are the two categories of SCBA?
closed circuit rebreathing
open circuit SCBA
two types of Closed circuit SCBAs
the difference is between the two is the source of oxygen
1st type, oxygen is provided by either HP o2 or o2 converted from liquid 02.
2nd type, “OBA” us where the water vapor in the exhaled breath reacts with a chemical to release oxygen.
available types of open circuit SCBAs
demand (negative face piece pressure)
pressure demand (positive face piece pressure)
Emergency Escape Devices
Emergency Escape Breathing Devices
What must you never use a Emergency Escape Breathing Device (EEBD) for? **
entry into a hazardous space
When cleaning the respirators, what must be avoided?
strong cleaning agents
temperatures above 43 degrees C (110 degrees F)
face piece sanitizing procedures:
immerse for 2 min in 50 ppm solution of iodine (15 ml iodine to 1.5 l of water)
rinse in clean warm water at temperature of 100 degrees F.
air dry in such a way as to avoid contamination or face piece distortion.
Storage of respirators
zip lock bag is preferred.
ensure it’s dry to prevent mildew
don’t allow for facepiece distortion
Maintenance and repair should not be performed unless:
personnel have the training.
reducing valves, regulators or alarms of atmosphere supplying respirators shall be returned to the manufacturer.
Requirements for fit testing procedures
qualitatively and quantitatively tested. annually thereafter.
must be performed wearing applicable safety gear.
authorized “fit tester”
what is qualitative fit testing
performed using isoamyl acetate (banana oil), saccharin mist, and irritant smoke (preferred method)
quantitative testing can only be performed by who:
shore activities
how often is qualitative fit testing done
initial and then annually
