Common models of a self-contained gas mask
Insulating gas masks of the IP series began to be produced for the first time in the USSR for military personnel. They entered mass production in the mid 80s of the ⅩⅩ century.
IP model - 4M
A small-sized device weighing up to 3.5 kg, with a continuous use time of up to 3 hours, a pendulum breathing system. You can use the IP - 4M, observing the temperature regime from - 40 to + 40 ℃. The device is designed for military personnel. It is used to protect against health threats on land. The IP - 4M model uses chemically bound oxygen.
The IP - 4m is started by pulling the safety pin out of the cartridge and rotating the screw until the screw fails or turning the trigger of the starting device. It is forbidden to start work in a gas mask if the starting device does not work. After one-time operation of the SP - 4m, the regenerative cartridge is replaced with a new one, the used one is disassembled and disposed of.
With correct and timely replacement of cartridges, IP - 4m can be used continuously for eight hours.
IP - 5
It differs from IP - 4 in a longer time of use. The device, weighing up to 5.2 kg., Has an additional attachment, consisting of a strap and buckles attached to the mask to prevent it from falling off under water. The rubberized bib included in the IP - 5 kit allows you to attach all the components of the device to it under water. The protective device allows you to submerge under water to a depth of 7 meters.
The device can be used at an air temperature from - 40 to + 50 ℃; water from + 1 to + 30 ℃. Serves for rescuing people, performing work under water, protection from radioactive substances and poisons when used on land.
IP - 6
In terms of technical characteristics and purpose, it is similar to IP - 4m. The temperature threshold for effective operation of the device is from - 20 to + 50 ℃. IP weight - 6 fully loaded - 3.6 kg. The time of continuous use of the gas mask is from 40 to 150 minutes. The IP - 6 model is often used when performing heavy construction, emergency, gas works.
Conclusion
An insulating gas mask is an invention important for many spheres of human activity, which makes it possible to protect the body from the harmful effects of toxic substances. The documents establish that persons who have undergone a medical examination, training courses, familiarized with the instructions for using and storing the device are allowed to work in an insulating gas mask

Appointment of civilian gas masks
The main purpose of these gas masks is to protect the population who lives in a hotbed of air pollution with various harmful elements.
Such equipment attracts attention with its ease of use, ease of dressing and low weight, the ability to breathe clean air without harmful impurities for several hours. The GP-7 gas mask is good because it can be used simultaneously in combination with special means that protect the head
In addition, modifications of this gas mask have a special drinking device, so you can stay in it for a long time. The convenient panoramic glass provides good visibility. A civilian gas mask consists of several elements:
- filtering and absorbing metal boxes;
- the front of the IHL;
- anti-fog film - one box;
- two insulation cuffs MNU-3;
- gas mask bags;
- a pressure cord made of rubber;
- operating instructions and product form.
The gas mask can be supplemented with the DPG-3 cartridge, which complements civilian and children's gas masks and thereby expands the scope of their application. The cartridge is able to protect the user from exposure to elements such as ammonia, chlorine, sulfur hydride, sulfur dioxide, hydrogen cyanogen, phosgene, amines.
