The most effective respiratory protection is a gas mask (or full face respirator). But it's not all that simple: most gas masks do not protect against carbon monoxide, which is formed in case of fire. Activated carbon does not have such property. Carbon monoxide, like other combustion products, is dangerous and even fatal. But there is a way out – hopcalite, a unique substance based on manganese dioxide obtained by electrolysis. Zelinsky Group is the only hopcalite producer in Russia and in the CIS countries since 1937.
Carbon monoxide burns on the hopcalite surface to form safer carbon dioxide (CO + O2 = CO2). Based on this simple reaction, an entire self-rescuer industry has grown. In case of fire, you just need to put on a self-rescuer (or escape hood) with a hopcalite filter and get out of the smoke. In case of fire, the ambient temperature is several times higher. That is why a fire-resistant hood that withstands open flames and hides a beard, long hair and glasses was added to the filter.
The self-rescuer is designed and manufactured specifically for evacuation in case of fire. We produce one universal size for everyone. The design of the hood excludes the intake of harmful substances.
It is clear that everyone should have a self-rescuer. But what may happen if you choose a cheaper option, for example, from AliExpress?
· the filter may break off (unreliable fixation of parts);
· the hood may tear when put on (poor quality material);
· the heat flow burns the head and respiratory organs (the material is not designed for high temperatures);
· the filter does not protect against carbon monoxide and combustion products or the breakthrough time is too short for evacuation (the manufacturer used low-quality raw materials).
All this time we are talking about the filtering self-rescuer. The external air (gas mixture) passes through the filter of the self-rescuer, and we breathe safely.
We make hopcalite ourselves, test it in the laboratory, roll up filters, assemble self-rescuers, seal it in a fire-resistant package, put it in a non-combustible compact bag, and test the whole batch again. We are confident in the quality of our products.
