The difference between gas masks and fire escape masks

Many people are not very clear about the difference between gas masks and fire escape masks. They always mistakenly believe that gas masks are worn when fire dangers occur. This is not the case. The difference between the two is very different. Once they are used interchangeably, light people will cause people to suffocate and the death of a serious person will be harmed.

First, the concept of understanding

1. Gas masks are actually a broad term. They can be understood literally as masks or masks that can prevent the intrusion of toxic substances into human respiratory organs, and belong to the class of respiratory protection products. It includes filter gas masks and insulative gas masks. The filter gas masks include self-priming gas masks (such as the popular pig nose mask) and long tube gas masks (one long tube ends Attached to the mask and filter box respectively, the filter cartridge is worn at the waist). The isolated gas mask is, as its name implies, the space where the human's breathing gas and toxic substances exist. They are two non-interfering places. Common long tube breathing. Equipment, air respirator, etc. Gas masks are used in a wide range of situations and are used in chemical fields, mining coal mine development, metal smelting, military defense, fire rescue, and health and epidemic prevention.

2. The fire escape mask is a narrow sense word and is suitable for the escape equipment for people in hotels, guesthouses and office buildings in the event of a sudden fire, and cannot be used in chemical firefighting and other workplaces. Fire escape masks cannot protect against all types of toxic substances. They can only protect against smoke, carbon monoxide, and toxic substances that are generated in the event of fire. Escape masks currently have few brands on the market. Foreign brands include Honeywell, Messin, and Zion Fire and Youan Fire. The specifications are generally defined in terms of the escape time used, from 5 minutes to 15 minutes. , 30 minutes, 40 minutes and 60 minutes.

Second, the difference between the two

1 different material

Filter-type gas mask, the body material of the mask is generally rubber, silicone, sealing performance is good, comfortable to wear. The mask body is a reusable type and can be used multiple times after cleaning. The filter cotton or filter box that filters toxic substances can be replaced on a regular basis. The escape mask and the mask body are made of aluminum foil flame-retardant and heat-insulating material. The eye-window has a wider view of the arc-forming structure, and the surface of the oropal mask is closely matched with the face and face, and the leakage coefficient is small. The use of special reflective materials on the hood enhances the firefield's recognition capabilities. Masks cannot be reused and are disposable protective equipment.

2. Anti-toxic substances are different

Gas masks have a wide range of protective properties, such as organic gases (benzene, gasoline, carbon disulfide, etc.), acid gases (sulfur dioxide, hydrogen sulfide, etc.), ammonia, chlorine, methylamine, mercury vapor, etc. Mask body only needs to replace different filters. The poison box can be realized; the escape mask can only prevent poisonous smoke (carbon monoxide, hydrogen cyanide acid and smoke chlorine, etc.).

3. Actually different

The use of gas masks, the commonly used filter rate is a gas mask, the site needs to have sufficient oxygen content, if the oxygen content meets the requirements, can be used for a long time; and the escape mask, the maximum use time is 60 minutes in the fire field, once used more than once In time, life will be in danger.

According to the above description, gas masks and fire escape masks are two different respiratory protection products. If it is a high-floor user's home, hotel, or office space to be backed up, fire escape masks can be selected. In chemical and other industries, professional gas masks must be used. .
