The purpose of a chemical protective suit is to shield individuals from the physical, chemical, and biological hazards they may encounter during work. Some chemicals offer no warnings and can pose invisible threats. The Occupational Safety and Health Administration (OSHA) created a chemical protective clothing manual on helping to determine four levels of chemical risk workers might be subject to, same as virus protective suit in virus situation like Covid-19.
Level A – This type of chemical protective suit provides the greatest level of skin protection available. This type of clothing must be vapor-tight, gas-tight, and splash-resistant. These garments need to be worn only when there is a potential threat to life and health. A self-contained breathing apparatus (SCBA) is required at this level, same as anti virus protective suit in virus situation, there are different levels for virus protective suit.
Level B/C – These chemical protective suit will protect from chemical splash, but not exposure from vapors or gases. The protective suit may or may not be completely encapsulated since a lower level of skin protection is required. Some chemicals may be known. An SCBA is also required at this level, the same as a disposable anti virus protective suit in virus situation, there are different levels for virus protective suit.
Level D – These varieties of chemical protective suits offer the lowest level of protection and are worn when no potential chemical hazard exists. These are normal work uniforms, offering minimal protection to minuscule exposure and can be disposable, same as virus protective suit in virus situation, there are different levels for virus protective suit.
Choosing the right material and style for your chemical protective suit is also important to your safety the same as a virus protective suit. When deciding which material, consider the following qualities:
Breakthrough Time- The time it takes a chemical to pass through a protective suit once exposure occurs, the same as a virus protective suit.
Permeation Rate- The speed at which a chemical passes through a protective suit once breakthrough has occurred, the same as a protective suit.
Suit Design – This refers to how the suit is stitched together. Coverall material can be joined together by a stitch or weld. Stitches can create pinholes that could allow chemicals to penetrate. Welded seams involve welding tape over the stitched seam and offer a greater level of protection, the same force corona protective suit.
