      It is believed that friends who are concerned about fire safety are not unfamiliar with the positive pressure air respirator. It can enable firefighters or rescue personnel to safely extinguish fires, rescue and rescue in harsh environments filled with smoke, gas, Steam, or hypoxia. Work. The relief valve device is equipped with a residual gas alarm. Within the specified cylinder pressure range, it can also send a sound signal to the wearer to remind the user to evacuate the site in a timely manner. It is one of the indispensable devices for modern fire rescue work.


      So how long is the life of a positive pressure respirator? How do you judge it to be scrapped?
      In general, the service life of a positive pressure respirator is about 10 years. Due to the continuous aging and wear of the components during the use of the positive pressure air respirator, the time is long, and various technical properties will naturally be reduced. To a certain extent, end-of-life treatment is required.
      To determine whether the positive pressure air respirator should be scrapped, it is necessary to pass the comprehensive technical identification and testing of the technical department.
      If it is found that the positive pressure air respirator used is frequently malfunctioning, and after many repairs, it still can not meet the relevant technical targets, or has been tested and confirmed by the integrated technology department to replace the product, it can be eliminated and scrapped.
      In addition, for some ventilators, the environment used is relatively poor. In order to ensure the safety of the use of ventilators, the use unit can appropriately shorten the service life of positive pressure ventilators according to actual conditions.
      Some high-quality air respirator materials are more particular, and the service life is longer than that of ordinary air respirators. The maximum service life can reach about 15 years.



      Disposal of end-of-life positive pressure ventilators
      For the pressure air respirator that has been scrapped, the user must take the scrap treatment in time, and can not be used so as not to bring safety hazards to the staff.
      The scrap of the positive pressure breathing apparatus shall be identified and stored separately from other breathing apparatus. The property right party shall dispose of the damage of the scrapped positive pressure breathing apparatus or the manufacturer of the air pressure breathing apparatus. They shall abide by the provisions of the Environmental Protection Law and refrain from arbitrarily disposing of or damaging the environment. Care should be taken not to reuse scrap parts due to improper disposal, which may pose potential risks to other protective measures.

       

      Maintenance of positive pressure ventilators
      So in order to reduce the air respirator wear and tear, premature scrapping, how should we use the correct maintenance?
      First, the mask: pay attention to friction and impact to rough, hard material, prevent the face mirror from grinding and affect the light permeability and clarity or even damage.
      Second, shoulder straps, belts: usually wear when wear as required to loosen, can not be too large, and at the same time prevent damage to some corrosive substances, found damage to repair in a timely manner.
      Third, the air supply valve: after use, buckle the dust protection cover to avoid entering the debris to cause congestion.
      Fourth, the back frame: when used, take lightly to prevent damage caused by collisions and friction with sharp materials. After each use, if you are soaked in water, you need to get dry and ventilated, avoid exposure. Keep each tightening band in its maximum position when saving.
      Pressure gauge: It is also an inspection when the pressure of the cylinder is checked. After the inspection, the memory balance is released to ensure that the pressure gauge and hose are not damaged under constant pressure; At the same time, it can not be used to measure excess pressure and avoid overload.
      Cylinders: Cylinders are mainly used to store compressed air. There are currently two types of steel and carbon fiber. Note that when rushing, the air must not exceed the rated safety pressure, and the air humidity must not be too large, which will cause the cylinder inner wall to oxidize; Can not be used in fierce collision and friction with sharp objects, light gas cylinders damage, heavy lead to blasting; If necessary, make a protective cover for the cylinder to prevent friction and damage. Steel cylinders shall also be coated with rust resistant paint to avoid oxidation of the outside of the cylinders; Gas filled cylinders can not be stored in the sun and at high temperatures to avoid damage or explosion.
      In addition to tell everyone a good news, before the sale of the positive pressure type of air respirator, tentatively this week for inspection. Friends in need are welcome to contact us for reservations!
