1SFFMA Training Objectives: 27-01.01 – 27-01.06 CVFD Training – SCBASFFMA Training Objectives:–
2Objectives (1 of 2)List two conditions requiring respiratory protection.List and explain the effects of oxygen deficiency and toxic gases on the human body.List one legal requirement for use of SCBA.List two types of SCBA.List four components of the SCBA used by the authority having jurisdiction.
3Objectives (2 of 2) Demonstrate two different SCBA donning procedures. Demonstrate routine inspection of SCBA.Demonstrate after-use maintenance and servicing.Demonstrate the servicing of an SCBA cylinder with the air-filling system.
4Introduction (1 of 3) SCBA an important item of PPE. SCBA allows firefighters to work in oxygen deficient atmospheres.Human body very vulnerable to oxygen deficient atmosphere.Respiratory protection policy must exist.SCBA required in an IDLH area.Click Here to View Video: SCBA Functions
5Introduction (2 of 3) Many changes in SCBAs since the 1970s Decrease in weightMust be positive pressureImproved designSCBA maintenance programsPASS devicesBetter training programsIncreased regulations
6Introduction (3 of 3) Improvements TechnologyRegulationsMandatesSCBA improvements are only as effective as the training and proficiency firefighters develop in using SCBA.
8Oxygen-Deficient Environments Humans and fire both require oxygen to survive.Oxygen deficiency is detrimental to the human body.Click Here to View Video: Proper Use of SCBA/ Effects of Smoke and FireClick Here to View Video: SCBA Standards, Types and Limitations
9Elevated Temperatures and Smoke Inhalation of heated gases can cause fluid to build up in the lungs and create long-term, irreversible damage.Combustion by-products are very irritating to the body.High temperatures can also cause severe burns to the respiratory system.
11Effects of Toxic Gases and Environments (1 of 2) Toxic gases are produced by combustion.These gases affect various body systems.Hazardous materials can increase the risk to firefighters.CO is one of the most lethal gases produced by fire.CO attaches to blood 218 times easier than O2.
12Effects of Toxic Gases and Environments (2 of 2) CO prevents distribution of O2 in the body, causing hypoxia.Without SCBA, a firefighter will not survive.Repeated exposure to toxins has long-term effects.
13Legal Requirements for SCBA OSHA - Respiratory Protection Standard Title 29 CFR29 CFR standard for all entries into IDLH atmospheresNFPA standards (1500, 1404, 1981)NIOSH 42 CFR Part 84
14Organizations Concerned with SCBA Design and Use STANDARDAPPLICATIONNational Institute for Occupational Safety & Health (NIOSH)42 CFR Part 84Requirements for design, testing, certifying SCBAOccupational Safety & Health Administration (OSHA)29 CFRRespiratory protection programs for SCBA useOccupational Safety & Health Administration29 CFRFire Brigade Standard, referencesNational Fire Protection AssociationNFPA 1404Standard for Fire Department SCBA ProgramNFPA 1500Standard on Fire Department Occupational Safety & Health ProgramNFPA 1981Standard on Open-Circuit SCBA for the Fire Service
15Limitations of SCBA (1 of 2) SCBA design and sizeIncreases weight and girthDecreases mobilityRequires good physical conditioningMust be aware of how long air will lastLimits visibilityVoice muffled and hard to understand
16Limitations of SCBA (2 of 2) Limitations of SCBA userFactors such as facial hair or weight loss can alter mask effectiveness.Lack of confidence can lead to anxiety.Training/experience will improve confidence and ability.Increased physical stress causes anxiety.Emotional state may affect respiratory rate and air consumption.
17Constant Training Is Essential Click Here to View Video: SCBA in Emergency Situations
23Open-Circuit SCBA — Cylinders (1 of 2) SCBA cylinders vary in material and type.USDOT regulates compressed gas cylinders.Quality of the compressed breathing gas has a direct effect on the performance of the SCBA.
24Open-Circuit SCBA — Cylinders (2 of 2) SCBA Air Cylinder CapacitiesRATED DURATION (MINUTES)MATERIALCYLINDER PRESSURE (PSI)CAPACITY COMPRESSED AIR (FT3)30Aluminum or Composite2,216444,50045Carbon Fiber3,000656088
25SCBA Regulator (1 of 2)Regulator is attached to the face piece or waist strap.Regulator has a pressure gauge.Regulator is activated by user’s breathing action.
26SCBA Regulator (2 of 2)The regulator maintains constant positive pressure airflow to the face piece.Units have low air supply warning alarm.NFPA 1981 requires two types of alarms.
27SCBA Face Pieces Annual face piece fit test is required. Exhalation valve keeps toxic gases out.
28Closed-Circuit SCBA Not used for regular firefighting operations Commonly used for hazmat operations and below-grade rescuesContains cylinder, filter system, regulator, and valves
29Open-Circuit Supplied Air Respirator (SAR) Air supply cylinder is remote from user.It provides user with long- duration air supply.It is used for hazmat operations and confined space rescues.
30Donning and Doffing SCBA (1 of 2) Perform safety check first.Use one of two methods.Over the head methodCoat methodSCBA is also mounted in seats.Never stand to don while apparatus is moving.After securing SCBA, don face piece.Click Here to View Video: SCBA Testing and Service/ Donning SCBA
31Donning and Doffing SCBA (2 of 2) The proper donning of a face piece is essential.After exiting hazardous area, remove SCBA. Remove face piece while waiting for assignment.Local protocol may require rehab after assignment.
35SCBA Operation and Emergency Procedures Firefighters must be proficient in:Safe use of SCBADonning and doffing proceduresIndividual limitationsLimitations of SCBA
36Safe Use of SCBA (1 of 2)Firefighters must be physically fit for respirator use.Accountability system should be in place.Must work in teams of two at a minimum.OSHA “two in/two out” regulation.PASS device must be activated.
37Safe Use of SCBA (2 of 2) SCBA operations should include rehab time. Stay hydrated during rehab.Air consumption will vary for all.Never remove the face piece in a contaminated environment.Low air alarm on one team member means the whole team exits.
39Operating in a Hostile Environment (1 of 2) Always check in/out with accountability officer.Always remain low.Check the environment.Never remove a face piece.Be aware of your location at all times.
40Operating in a Hostile Environment (2 of 2) Ventilate as you advance.Check outside openings.Maintain contact with team members.Never enter a hostile environment alone.
41Restricted Openings Never remove face piece! Loosen straps and rotate SCBA under arm.Remove harness and hold SCBA as a last resort.Do not lose contact with SCBA.Maintain control of unit.Practice procedures regularly.
43Emergency Procedures with SCBA Remain calm.Immediately exit hazardous area.Activate PASS device.Announce your emergency over the radio.If regulator or face piece fails, use bypass valve.Buddy breathing is only a last resort.
44Inspection and Maintenance of SCBA Have SCBA ready to go at all times.Routinely inspect SCBA.Remove unit and check it after each use.Monthly operational check should be done.Service less than full cylinder.
45Servicing SCBA Cylinders Test and certify air source.Cylinders must have current hydrostatic test date.Fill stations must have fragmentation containment devices.Always follow manufacturer’s recommendations.Remember, fill rates will vary.
47Summary SCBA is one of the most important PPE items. Both SCBA and the user have limitations.Firefighters must be familiar and comfortable with use of SCBA.Firefighters need to be proficient in the proper and rapid donning of SCBARoutine inspections and maintenance are important.
