HYZ2 oxygen breathing apparatus

l also return

Fire accidents indicate that more than 85 % of the victims were killed due to hypoxia due to radon gas poisoning. HYZ2 self contained breathing apparatus known as chemical oxygen fire self contained breathing apparatus (see FIG. 1) with full isolation, self-circulation, no autogenous oxygen meter, to overcome the current of purifying respirators commonly used in fire oxygen concentration to less than l7% It will lead to the shortcomings of using anoxic asphyxia, and at the same time solves the problem that filter respirator can only filter certain types and concentration range of toxic gas.

Figure 1 HYZ2 self-rescue breathing apparatus

HYZ2 self-rescue breathing apparatus can effectively solve the toxic gas generated in the fires of China's high-rise buildings, underground sites, subway tunnels, etc., and solve the problem of self-rescue and escape in an oxygen-deficient environment. Persons in distress can wear the respirator, completely isolated from the external poisonous environment, and can breathe oxygen when they use self-contained oxygen for escape. This will greatly increase the survival probability of the escapee.

2 product features

(1) Wide range of protection and high safety performance - When personnel are in a hazardous gas environment, they can be effectively protected.

(2) Long time of protection —The running protection time of running is 30 minutes , and the time of sitting and waiting for protection is more than 70 minutes .

(3) comfortable and easy to use, safe and reliable - - products according to GA 411 - 2003 "Chemical oxygen self contained breathing apparatus Fire" standard production, part of the performance is higher than the national standard, adequate oxygen supply, suction temperature around 40 ℃ (≤ 55 national standards °C ) to ensure breathing safety.

(4) Rapid oxygen production and comfortable breathing - Ensure that the rapid oxygen concentration exceeds 17 % during the initial period of wear , oxygen concentration is greater than 21 % during the rest of the protection period , and breathing is comfortable, the resistance is low, and oxygen is sufficient.

3 Scope of application

HYZ2 self-rescue breathing apparatus is suitable for producing toxic and harmful gases and oxygen-deficient atmospheres in fires of high-rise buildings, underground places, subway tunnels, etc. It can also be used for short-time anti-chemical, anti-atomic and biological warfare agents in the event of terrorist attacks; it can also be used In the event of leakage of toxic and hazardous substances from chemical industry and other industrial sites, operators wear them so that the accidents can be dealt with quickly and they can escape from the danger scene in time.

4 working principle

When using the apparatus, and isolated from the external environment, without any outside fire smoke and toxic gases, hypoxia harmful influence by moisture exhaled by the wearer (HO) and carbon dioxide (CO:) and "An oxygen Laid" specific raw oxygen The chemical reaction of the agent generates oxygen (O) for the wearer to breathe and use for rescue. The working principle is shown in Figure 2 .
