SCBAOrientation and Annual Refresher Training
IntroductionSCBA are one of the most effective and potentially hazardous pieces of equipment used in the fire service. They allow us to go into extremely hazardous situations and may give a false sense of security.It is extremely important to:
Know their limitations and usesUnderstand how they operateKnow how to maintain and check themBe familiar with the packs safety featuresBe able to use the pack in zero visibility environments
IntroductionValues and Expectations
Use good judgment and promote safety at all timesObey the law; follow appropriate directives and rulesProtect your co-workers welfareWork competently Be pro-active
Course ObjectivesDescribe how to recognize medical signs and symptoms that may limit or prevent the effective use of the respiratorsDescribe why the respirator is necessary and how improper fit, usage, or maintenance can compromise the protective effect of the respirator.Describe what the limitations and capabilities of the respirator are.
Course Objectives Cont.Demonstrate how to inspect, put on and remove, use and check the seals of the respirator.Demonstrate how to use the respirator effectively in emergency situations, including situations in which the respirator malfunctions.Demonstrate the procedures for maintenance and storage of the respirator.

Respiratory SafetyLimitations and Capabilities of Respirator
Provides approximately 45 minutes of supplies airNo protection from liquids, vapors or gases that are toxic by absorptionMalfunction, misuse, or running out of air may result in severe injury or deathMalfunctions can be reduced by proper maintenanceMisuse can be avoided by insuring proper fit and by using correct donning proceduresRunning out of air can be avoided by constant situational awareness
Respiratory SafetyPhysical Stresses
Heart attack is still the NUMBER 1 killer of firefightersUsing SCBA increases cardiovascular work and heat stressSign and symptomsShortness of breathExtreme fatigueChest painLight headednessConfusionPreventionKeep hydratedKeep physically fitRehab frequentlyKnow your limitations (work rate consumption)Quit before there is a problem
Pack FamiliarizationManual on share drivePacks on each table
Pack FamiliarizationCylinder valvePurge valveStrapsLow air alarms - Vibra-Alert @ 1000 psi
Pack FamiliarizationHUD display
FULL cylinder - two green lights glowing near the center of the display.THREE-QUARTERS cylinder - single green light glowing.ONE-HALF cylinder - yellow light flashing slowly at one second.ONE-QUARTER - red light at the far left flashing rapidly. LOW BATTERY indicator at the far right of the display will light for twenty seconds and then begin to flash slowly at once a second. LOW BATTERY indicator is circular.

InspectionsSCBA Resource Manual
Contains all the information about our respiratory protection programOne is located at each station
InspectionsDaily, Weekly, Monthly & After Use
Instructions located in resource manual & apparatus bindersDaily and weekly inspections are documented on the apparatus inspection formsMonthly and after use/in service inspections are documented on a separate form located in the apparatus inspection bindersIt is imperative to perform and document monthly, after use/in service inspections. Failure to do so may lead to injury, death and/or heavy fines.
DEMONSTRATIONDailyWeeklyMonthly, After Use/In Service
CleaningUse a mild liquid soap to clean both SCBAs and masksUse multi-wash for disinfecting purposesThese items are conveniently located in a caddy beneath the sink in the SCBA room, along with 3 buckets for mask washing
Maintenance is covered in scheduled checks and by having each pack bench tested every two yearsMasks
Each member is responsible for inspecting and maintaining his or her own maskRegularly inspect the face seal and lens for cracks or holes and inspect the retainer screws for tightness. Assure that all pieces are present and functioning properly.
RepairsOperator repairs should be limited to the following:
Replacing the nipple seal gasketReplacing regulator gasketRegulator tear down for disinfection purposesAll others should be tagged O.O.S. for a field level maintenance technician
Out of Service (O.O.S.) EquipmentOOS Tags Should contain the following:
NameDateDescription of the problemUtilize available diagrams located in the SCBA room to properly identify O.O.S. parts whenever possibleAttach an O.O.S. tag to the appropriate part whenever possibleAlways store O.O.S. equipment separate from in-service equipment
DEMONSTRATION(Document on Practical Evaluation Sheet)Nipple Seal GasketRegulator GasketRegulator Tear Down
Bottle FillingMACO Air CompressorCheck and fill oil to the appropriate levels when necessary prior to each usePerform the following on the weekly checks:Allow the compressor to run approx. 25 minutes by opening the main drain slightlyAfter closing the drain, allow the compressor to fill and document the oil pressure and each stage pressure at completionDocument all of the above in the compressor log
