A set of long tube respirators consists of three parts: gas mask, long tube and blower. Therefore, maintenance is also started from these three aspects, mainly divided into three steps of cleaning, inspection and storage;
1. Cleaning 1. Remove the gas mask. 2. Remove all parts from the mask, such as the headband. 3. Use a neutral detergent solution to clean the mask and breathing tube. 4. Rinse with water, the water temperature does not exceed 49 °C. 5. After cleaning, place the gas mask in a ventilated place to dry, remember not to use a hair dryer to dry. 6. When disinfecting, soak the gas mask for 10 minutes in a 10% aqueous solution of household bleach, then rinse with water and air dry. Long-tube respirator mask maintenance is very important. Remember to use organic solvents to clean any part of the long-tube respirator. Although the organic solvent is air-dried after cleaning, it can easily lead to component aging.
2. Inspection After the cleaning is completed, the respiratory protection products should be inspected to ensure that the equipment is in good working condition and can be used at any time: 1. Check the mask and breathing tube for cracks, abrasion and dirt. Make sure the mask, especially the gasket, is not deformed. The mask material should be soft and should not be stiff. 2. Check if the headband is elastic. 3. Check all plastic parts for cracks or aging. 5. If any parts are damaged, try to use the same brand specifications for repair or replacement.
3. Storage The anti-virus mask is sealed with a clean sealed bag, and then stored in a clean cabinet together with the long tube and the blower. The environment is as dry as possible, free of pollution, and no direct sunlight.
