Description 2 Description The MSA G1 - referred to hereafter as SCBA - is a pressure-demand self-contained breathing apparatus (SCBA) operating independent of the ambient air for use in atmospheres immediately dangerous to life or health. Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a regulator and a facepiece. The exhalation air is released directly into the ambient atmosphere.
Description 2.1 G1 Facepiece The facepiece provides breathable air from the regulator past an inhalation valve to the inside of the lens (to minimize lens fogging) and then through the check valves into the nosecup. Exhaled air is directed out of the exhalation valve by the nosecup directly to ambient air. The face seal provides a snug, comfortable fit, and tight seal. The facepiece is available in 3 sizes (small, medium, large) and the nosecup is available in 3 sizes (small, medium, large).
Description 2.2 G1 Regulator (also known as Demand Valve) The mask mounted G1 Regulator is a pressure-demand regulator, which maintains a positive pressure in the facepiece while the SCBA is in use. The positive pressure regulator reduces the pressure coming from the pressure reducer further to provide breathable air to the user. The regulator is connected to the facepiece with a fixed position Push-To-Connect (PTC) connection. The regulator has two cover options available, purge and solid cover.
Description 2.4 Cylinder and Valve Assembly The cylinder and valve assembly store high pressure air which will be reduced to provide the user breathable air. Cylinders are available in multiple pressures and rated service times. The valve assembly provides the user the ability to open the pressure to the rest of the system.
Description Primary Low Pressure Warning Device (Bell) The primary low pressure warning device alarms when there is approximately 35 % of the SCBA’s rated service time remaining and when the cylinder valve is first opened, providing an audible indication that the alarm is working properly. NIOSH regulation states that the primary low pressure warning device must alert the user at 35% 2%. MSA sets all low pressure warning signals to the mean of the requirement, hence 35 %. Remaining Service Time (Approx.
Description When the control module is being read by the user, no buddy lights on the control module will flash and a white gauge light will illuminate, to enable the user to read the gauge and display. If the SCBA is equipped with the optional telemetry module, the radio link status and evacuation alarms are displayed. The integrated PASS motion sensor is housed within the control module. The ALARM button of the control module activates the full PASS alarm with or without air pressure.
Description 2.7 G1 Harness and Carrier Assembly The harness and carrier assembly consists of: - Backplate (houses the power module, battery module, and pressure reducer) Cylinder band with latch to hold the cylinder Shoulder pads Adjustable pull straps Lumbar pad Waist belt Regulator Keeper Chest strap (optional) Shoulder Straps The shoulder pads are available in two options; standard and serviceable.
Description 2.8 G1 Speaker Module (Optional) The speaker module amplifies and clarifies the speech from the facepiece during use. When inhaling, the breathing sound will not be amplified (optional). The speaker module is turned OFF when the complete SCBA is turned OFF and can also be activated/deactivated with its button. Pressing of the button is acknowledged by a beep. 2.
Size Selection 3 Size Selection Regardless of facial dimensions and respirator sizing charts, an actual respirator fit test, either qualitative or quantitative must be performed to ensure the correct respirator size selection. (1) Fit test the respirator size relative to your facial features and dimensions. The safety administrator or program manager might assist in selecting the initial size to try. (2) Carefully don the mask and conduct a negative pressure seal test.
Size Selection 3.1 Respirator Fit Test WARNING The user must perform a respirator fit test (Quantitative Test or Qualitative Test) and follow all warnings and limitations specified. Failure to do so can result in serious personal injury or death. A qualitative or quantitative respirator fit test must be carried out routinely for each wearer of this respirator to determine or confirm the amount of protection that the respirator provides.
Visual Inspections 4 Visual Inspections Conduct the visual inspections: Upon receipt, daily, and after use. Inspect the entire SCBA after it is cleaned and disinfected. WARNING DO NOT inspect the SCBA before cleaning if there is danger of contacting hazardous contaminants. Clean and disinfect first, then inspect. Failure to follow this warning can cause inhalation or skin absorption of the contaminant and result in serious personal injury or death. NFPA-1500, as well as ANSI standards Z88.2 and Z88.
Visual Inspections 4.1 4.2 Facepiece (1) Inspect the lens for cracks, scratches, deformation, and color change. (2) Check the facepiece rubber for a tight seal and secure fit to the lens ring. (3) Ensure the exhalation valve is clean and operates easily. The valve must move off the seat and return when released (from inside the facepiece). (4) Inspect the facepiece inlet for damage. Ensure the inhalation valve is in place.
Visual Inspections (3) Inspect the high pressure relief valve for damage. Ensure the relief valve label is not damaged and that the relief valve ports are not showing. If damaged, remove the SCBA from service and replace the relief valve. (4) Reattach handwheel to the cylinder valve. Threaded connect: (5) Quick connect: Push the quick connect coupling onto the cylinder valve adapter until an audible snap is heard. The handgrip will rapidly rotate approx.
