1.Air breathing apparatus introduction:
Self-contained Air Breathing Apparatus(SCBA)
The SCBA is designed for protecting:
l. Toxic particles and aerial fog
2. Toxic gases
3. The oxygen concentration is less than 17%
4. The smog caused by fire disaster
Remark: The SCBA has the function of respiratory protection and face protection.
When used in bad working environment, be sure to use auxiliary protective equipment at the same time, such as: Protective Gloves,Safety Boots, Airtight Protective Clothing, Safety Helmets.
The SCBA provides user sufficient air by equipped with one or two gas cylinder. The air is compressed to store in the gas cylinder (the pressure of the gas cylinder is 30MPa).But the air in the gas cylinder can't be breathed by user immediately. It must be decompressed twice through the related parts. First, the pressure regulator decompresses the high pressure air to 0.7MPa, and then transporting it into the medium-pressure pipelines, at last, through the air supply valve, the air is decompressed again to the positive air which can be breathed by the user.
Because the air provided by air supply valve is positive air, the pressure inside the face mask is always higher than outside working environment. So the toxic gas and aerosol and smog can't enter into the face mask, which fully protect the safety of users.
