3 GENERAL SAFETY INFORMATION Intended Use The 3 BE-12 Series Tychem QC Head Cover is a loose fitting, positive pressure respiratory inlet covering. These loose fitting facepieces, when combined with an appropriate powered air purifying blower unit (PAPR), are designed to provide respiratory protection against certain particulates, organic vapors, acid gases and other inorganic gases. (Fig. 1) The head cover features a wide-view faceshield and a Tychem QC faceseal. It is held in place on the head by a sewn-in, elastic headband. Breathing air is supplied from a breathing tube connected to a snap-in hose connector, which is sewn into the back of the head cover. Breathing air travels through the open space at the top of the head cover, down over the user s face and down through the holes in faceseal. The BE-12 Series head cover is available in polycoated Tychem QC material. Tychem QC offers splash protection against many inorganic acids, bases and other liquid chemicals such as pesticides. This fabric is made from Tychem that has been coated with 1.25 mil polyethylene. Note: This product contains no components made from natural rubber latex. Do not use the BE-12 Series head covers with facial hair that interferes with the faceseal. Users should be clean-shaven where the respirator s faceseal comes into contact with the user s face. Failure to do so may reduce the effectiveness of the respirator and result in sickness or death. Note: Inspect emergency use respirators on a monthly basis. Fig. 1 3

10 Connecting Breathing Tubes to the PAPR Unit Refer to the NIOSH Approved System Configurations table for a list of approved powered air purifying respirator (PAPR) belt-mounted units and breathing tubes needed to form a complete positive pressure respirator system. The user must read and follow all User Instructions supplied with the PAPR blower unit. Incorrect operation of the PAPR motor blower could result in reduced airflow, interruption of airflow to the headpiece or contamination of breathing air and may result in sickness or death. Check that the rubber o-ring gasket is in place at the end of the breathing tube connector. Position the breathing tube connector so that its two locking studs are aligned with the openings of the two L-shaped slots on the PAPR or SAR valve outlet fitting. Press in straight and twist so that the locking studs are engaged at the end of the L-shaped slots. Inspect the Respirator Condition Thoroughly Each time the respirator is used, you must complete the inspection procedures recommended in the Inspection, Cleaning and Storage section. Inspect PAPR components according to the instructions in the User Instructions provided with the applicable components. Donning the Respirator Always don the respirator in an area where the air is clean. Failure to properly don this respirator before entering a hazardous atmosphere may result in sickness or death. The 3M BE-12 Series head cover system is made from polycoated Tychem QC material in regular (for head sizes 6 1/2 to 7 3/8) and large (for head sizes 7 to 8). Since the sizing guidelines are general, the best fitting size of head cover for you may depend on your facial size and shape. Select the size that fits most comfortably and matches your head size. Remove the protective covering from the faceshield. To achieve the best fit, the head cover should be worn with the headband around your forehead and the straps in the top of the head cover in contact with the top of your head. The elasticized edge of the faceseal should come in contact with your face under the chin and along the cheeks. It is important to ensure the breathing tube is not twisted after the complete system has been donned. Turn on the battery pack to draw ambient air through the filter/cartridge. With the respirator in operation, enter the contaminated area, breathing normally. Keep the air supply hose or PAPR assembly away from equipment, vehicles and other physical and chemical hazards. User Performance Check 1. Prior to connecting the breathing tube to the head cover, complete the performance check and verify that the airflow is adequate according to the User Instructions provided with the 3M beltmounted powered air purifying respirator. 2. Observe the condition of the breathing tube in the air inlet at the back of the head cover. Verify that the air inlet is not twisted or obstructed in any way. 3. Place your hand inside the head cover, in the area above the faceshield. You should feel the air entering the head cover. 10

11 Enter the Contaminated Area Before you enter a hazardous atmosphere wearing this respirator, you must inspect the respirator, complete a user performance check, and don the respirator according to the instructions in these User Instructions and the User Instructions provided with the components of the system you are using.
