  4. OBJECTIVES • Identify and describe the different components of the MSA breathing apparatus.

  5. OBJECTIVES 2. Demonstrate knowledge and proper use

  6. OBJECTIVES 3. Properly Don and Doff the SCBA

  7. OBJECTIVES 4. Identify careand maintenance

  8. OBJECTIVES 5. Demonstrate proper Transfill technique

  9. OBJECTIVES 6. Demonstrate the proper use of the ICM TX* and identify the alarm indications *ICM TX is the current PASS device used in the department.

  10. OBJECTIVES 7. Demonstrate use of emergencybypass valve

  11. OBJECTIVES 8. Replace an exhausted cylinder

  12. OBJECTIVES 9. Demonstrate a positive and negative pressure fit.

  13. OBJECTIVES 10. Cold Weather Operation

  14. In-Service Training: • Orientation • Mask selection and fitting • Documented mask fit testing • Assign masks to firefighters • Performance objectives • Add air packs to apparatus

  15. Terminology: • ANSI - American National Standards Institute • APR - air purifying respirator • Audi-Alarm - MSA bell alarm at base of pack, activates at 25% cylinder volume • HUD - Heads Up Display • ICM or ICMTX* - Integrated Computer Module with pressure gauge and Redundant Alarm. *No pressure gauge on TX units.

  16. Terminology, cont’d • IDLH - atmosphere Immediately Dangerous to Life and Health • MMR - Mask Mounted Regulator (also referred to as 2nd stage regulator) • NFPA - National Fire Protection Association • NIOSH - National Institute for Occupational Safety & Health

  17. Terminology, cont’d • Redundant Alarm - ICM 2000 w/gauge or ICMTX w/out gauge. • Transfill - the process of sharing air via the URC from a donor scba (2,000psi+) to a receiving scba • URC - Universal Rescue Connection

  18. CHEMICAL CONTAMINATION • CO • CO2 • HYDROGEN SULFIDE • HYDROGEN CYANIDE • NITROGEN OXIDES • VINYL CHLORIDE • HYDROCHLORIC ACID

  19. CHEMICAL CONTAMINATION • SULFURIC ACID • NITRIC ACID • FORMIC ACID • ACETIC ACID • CARBON TETRACHLORIDE • VINYL CHLORIDE • BENZENE

  20. CHEMICAL CONTAMINATION • POLYAROMATIC HYDROCARBONS • (METALS) CADMIUM, CHROMIUM • HYDROGEN CHLORIDE • PHOSGENE • PCB’S • ASBESTOS • CREOSOTE

  21. CHEMICAL CONTAMINATION PLASTIC DECOMPOSITION PRODUCTS • POLYCARBONATES • POLYSTERENE • POLYURETHANE • PVC

  22. CHEMICAL CONTAMINATION • ARSENIC • CHLOROPHENOLS • ETHYLENE • FORMALDEHYDE • ORTHOTOLUIDINE

  23. SECTION 2 MSA FIREHAWK MMR INTRODUCTION

  24. COMPONENTS Seven Major Sub-Assemblies • First Stage Regulator • Second Stage Regulator • Air Cylinder • Audi-larm • Carrier and Harness • Facepiece • Redundant Alarm

  25. FIRST STAGE REGULATOR Two versions exist: Standard and PR14, both perform the same function Standard PR14

  26. Second Stage Regulator MMR second stage regulator shown in belt holster position. Regulator is Pressure Demand.

  27. AIR CYLINDER Green band on cylinders indicates High Pressure (4500psi) Yellow bank on cylinders indicates Low Pressure (2216 or 3000psi)

  28. Audi-larm

  29. Carrier and Harness Vulcan Style Airframe Style

  30. Facepiece

  31. Redundant Alarm or PASS device ICM 2000 Series ICM TX

  32. DONNING The Air-Pack

  33. Warning! • The model used for this piece is extremely good looking and intelligent.

  34. DONNING • Remove Facepiece from pouch • Check cylinder pressure. Min 4000 • Reach inside right shoulder straps, grasp the redundant • alarm and pressure gauge, slide left arm through the Left shoulder straps

  35. 4. Bend over slightly, attach chest strap

  36. 5. Fasten the waist strap, and pull tight for a snugfit. The weight is designed to be carried on the waist, not the shoulders.

  37. 6. As you straighten, pull the strap tabs out and adjust for a comfortable fit. 7. The shoulder and waist strap ends must be tucked in and lay flat across the body.

  38. DONNING the FACEPIECE 1. Loosen the neck straps so the end-tabs are at the buckles.

  39. DONNING the FACEPIECE 2. Insert your chin into the facepiece. Note: harness may take a “memory” if stored over mask. 3. Pull the harness “net” over the crown of your head.

  40. 4. Tighten the neck straps; if necessary tighten the temple strap adjustments. Tuck in the straps so they lay flat across the head.

  41. Facepiece fit check First, check the inhalation valve. Inhale. If you do not receive sufficient flow of air, do not use the facepiece. The facepiece must be repaired or replaced.

  42. Facepiece fit check To check for facepiece fit, hold your hand over the inlet and inhale. Hold your breath at least 10 seconds. The facepiece should collapse and stay collapsed against your face. If it does not, readjust the facepiece and test again. If this does not correct the leak, do not use the facepiece.

  43. Test the exhalation valve, take a deep breath and hold it. Block the inlet with the palm of your hand and exhale. If the exhalation valve is stuck, you may feel a heavy rush of air around the facepiece. You may need to exhale sharply to open the valve if this does not release the valve, do not use the facepiece

  44. Don Hood and Helmet

  45. Open the Cylinder Valve fully If air is flowing, push in the slide button on the MMR to stop air flow Listen for any sound of hissing or popping from the Audi-larm Alarm or quick fill valves. If heard, place out of service.

  46. As the pressure rises from 50 to 200 psig, both visible and audible alarms activate automatically, indicating that the alarms are functional. When the system is fully pressurized, the alarms enter the Monitor(normal) mode.

  47. Warning If the Audi-larm fails to ring, ICM, or HUD system fails to light and tone, place the SCBA out of service. All gauges should be within 225 psig of each other at 4500 psig. If not, place the SCBA out of service. Failure to follow these precautions may result in serious personal injury or death.

  48. Push the release buttons to remove the MMR from the standby belt mount

  49. Installing slide Mask Mounted Regulator • Grasp regulator and orient regulator so that the red bypass knob is pointing to the right and slide connector is on top.

  50. Installing slide Mask Mounted Regulator • Slide regulator onto rail (fast track) of facepiece cover. Slide regulator down the rail until regulator stops.
