Respiratory protective equipment inspection and maintenance

(1) Respiratory protective equipment The respiratory apparatus is inspected before and after each wearing to check whether the protective equipment components are complete, whether there is old damage, timely replacement of expired breathing, inhalation valves, headbands, sealing gaskets, etc.; masks should be damaged Timely replacement; self-loading of activated carbon filter cartridges and canisters is not permitted; self-assembly of respiratory protective equipment is not permitted.
(B) After the use of respiratory protection products Respirator management is an extremely important task, regardless of the time sooner or later or fatigue, should be the first to return the respirator to work ready state, and pay attention to the following requirements:
1. Used purification tanks must be replaced with absorbents. The cleaning tank can not be cleaned so as not to accelerate the corrosion.
2. The oxygen cylinder is refilled with oxygen.
3. Masks, breathing hoses, etc. should be cleaned and disinfected.
4. Clean the housing, but it must be waterproofed into the regulator.
5. Questions that exist or are found in use are to be repaired or scrutinized.
6. When installing each part, carefully inspect each joint gasket for presence or damage.
7. When cleaning parts, prevent collisions and avoid damage, resulting in poor air tightness.
(3) Precautions for the daily custody of respiratory protective equipment The maintenance of respiratory protective equipment must be regularly checked and maintained according to the requirements in the instruction manual, and cleaned and disinfected, and placed in a sealed bag for storage. Filters are not allowed to be cleaned, and they should not be stored in open positions. After the filters fail, they must be replaced promptly to ensure the effectiveness of the filtration.
1. Respirator and spare parts should avoid direct sunlight, so as to avoid aging rubber parts.
2. From the perspective of hygiene and prolonging the life of protective articles, rubber masks should be cleaned frequently, mild detergents should be used, and masks should not be cleaned with organic solvents; any filter material should not be washed.
3. The respirator is in direct relation with the human body's respiratory organs. Therefore, the respirator is required to be kept clean. The respirator should prevent the contamination of dust or other toxic and harmful substances.
4. The breathing apparatus must not be contaminated with grease.
5. Respiratory storage temperature should be between 5 - 30 °C, relative humidity in the range of 40% to 800%, the distance from the respirator heating equipment should be greater than 1. 5m, the storage room air must not have corrosive gas . Non-use filter cartridges should be kept in a sealed container to prevent moisture.
6. The storage and operation personnel of oxygen cylinders must strictly abide by the relevant rules and regulations and must not contaminate grease. Don't put it in the sun in summer. The distance from the open fire is generally not less than 10m. Oxygen within the cylinder can not be used up, leaving 0. 05MPa of residual pressure.
