5 TORNADO T8/SM and T8/ML Respiratory Protective Systems WARNING TORNADO powered respirators are designed for use by personnel who are familiar with workplace hazards. This leaflet must be read together with the user leaflets for T/POWER and T/FILTER. DO NOT use in oxygen deficient atmospheres (<19.5%), confined spaces, stills, tanks, or areas immediately dangerous to life or health. DO NOT use equipment that is damaged. Check that the type of filter(s) used with T/POWER are suitable for the workplace hazard. DO NOT use if there is no airflow from the T/POWER or if the airflow output is low (see the Flow test detailed in T/POWER). DO NOT confuse the markings on a filter relating to any European Standard other than EN12942 with the classification of this device when used with this filter. DO NOT use T8 with T/POWER switched off. In the unlikely event that T/POWER fails to supply air while in a hazardous area, continue to breath from the half mask and go immediately to a safe area. The halfmask will continue to provide a degree of respiratory protection. T8 is not suitable for use with T/A/LINE. T8 must not be used where contaminant concentration exceeds 20 times its Occupational Exposure Limit, or 1000 ppm by volume. T8 must only be used with the T8 breathing hose. DO NOT use other TORNADO breathing hoses. It is unlikely that the requirements for leakage will be achieved if hair, spectacle side arms or clothing intrude into the faceseal.

6 INTRODUCTION To aid component identification in the following procedures, bracketed numbers after a component show component's location in the T8 diagram inside the front cover. DONNING Note: Initial donning procedures should be supervised by a competent person. Select the appropriate size of mask: S/M or M/L. 1. Check that all parts of T8 are clean and in good condition. 2. Check that the breathing hose seal (8b) is in place and in good condition and screw the breathing hose (8a) firmly, hand-tight, onto the halfmask (Fig 1). Do not over-tighten. 3. Adjust the harness (1) so that the buckle is away from the mask and the head pad rests on top of the mask. Place the strap around the neck (Fig 2). Note: Once a comfortable fit has been achieved for a given wearer, there should be no need to alter the head-strap length when donning in the future. 4. Place the halfmask on the face and adjust until the faceseal (2) fits smoothly against the face. 5. Pull the head pad onto the crown of the head (Fig 3) and adjust the harness, feeding the harness through the anchors to equalise the pull on the anchors. 6. The mask should feel firm against the face with no undue movement. If it does not fit, or is uncomfortable, adjust the harness (1) length using the nape buckle (It may be easier to do this prior to donning the mask). Excessive tightening causes discomfort and may distort the face seal. 7. Test the faceseal by blocking the breathing hose inlet with the palm of the hand and inhaling. Check that the mask pulls onto the face until the wearer exhales. If there is a leak, check the faceseal, breathing hose seal (8b) and the exhalation valves (4a). It may be necessary to try the alternative size of mask. Do not use the mask if a good fit cannot be achieved. 8. Arrange the breathing hose so that it trails freely down the back and is not kinked, likely to snag, or be crushed. 9. Follow the instructions in the T/POWER leaflet to: Attach the breathing hose to T/POWER, Perform the airflow test, and Check the filters. AFTER USE WARNING: DO NOT remove the halfmask until well clear of the hazard area. 1. Take off the halfmask and undo the breathing hose. 2. Clean the mask and the outside of the breathing hose with a synthetic sponge moistened in a mild solution of soap and warm water, or TriGene solution. Note: Water MUST NOT enter the breathing hose. 3. Rinse the mask thoroughly under clean running water and hang it by the harness until thoroughly dry. DO NOT use radiant heat or sunlight to speed drying. 4. Use TriGene wipes to sanitise the faceseal. 5. After cleaning, check that all components are in good condition. Worn or damaged items must renewed prior to further use. MAINTENANCE Important: Check the valve flaps (4a) and (4b) visually every 3 months to ensure that they are clean and undamaged. Check that the faceseal (2) and valve flaps are flexible. Valve flaps must be replaced annually. Important: The breathing hose elbow is glued to the halfmask shell (3) and must not be removed. If an elbow is removed or damaged, the shell assembly must be renewed. 2

7 Important: Exhalation valve flaps should be as new with no damage. They are marked with a code indicating the year of manufacture. The letter Y' corresponds to 1994 and a dot is added each year thereafter, so Y...' is Discard valve flaps that are more than 6-years old. Storage Note: Plastic and rubber components must be stored in clean dry conditions, away from direct sunlight and heat, within a temperature range 10 o C to 30 o C and in humidity not exceeding 65%. Replacing the Harness - Push the harness anchors from the shell (3) to free the harness. Push the replacement harness anchors into the slots in the shell assembly. Check that they click into place and are securely attached. Replacing the Exhalation Valve Flap and Valve Cover - There are two exhalation valves. To replace an exhale valve flap, or valve cover: grasp the lower edge of the green valve cover (5) and pull off the covers. Grasp the valve flap (4a) and pull from the faceseal (2). Check that the replacement flaps are in good condition, and carefully pull the stem of each flap through the centre of the valve frame, until the flap lies flat against the frame. Replacing an Inhale Valve Flap - Pull the valve flap (4b) from the locking ring (6). Check that the replacement flap is in good condition and carefully attach the flap over the tab on the locking ring. Check that the flap is flat against the frame. Replacing the Shell Assembly, Locking Ring and Thrust Washer - Unclip and remove both exhale valve covers (5). Turn the inhale valve locking ring (6) anti-clockwise and remove it. Align the notches on the thrust washer with the tabs on the elbow, and remove the thrust washer (7). Remove the shell. Fit the replacement shell (3) over the faceseal and ensure that the exhale valve apertures engage in the groove in the rim of the valve frames. Fit the replacement thrust washer (7) and locking ring (6), taking care to align the notches on both with the tabs on the elbow. Clip both exhale valve covers (5) into place. Push the harness anchors into the notches on the shell. Breathing Hose and Seal - Unscrew the breathing hose and discard the seal if it is 6-years old, if it is damaged or cannot form a good seal.
