What is a Level A Hazmat Suit?
Total encapsulation, highest levels or protection for skin, eyes, and respiratory system dealing with hazardous levels of mists, vapors, gases, and particles.
Used when work operations and/or function deal with high risk and potential for exposure, immersion, or chemical splash.
Consists of a full-face piece self-contained breathing apparatus or a supplied air respirator with an escape cylinder.
A worker must wear correct footwear such a steel toe boots with shanks on the outside of the suit.
Communication is also used to qualify as a Level A encapsulated suit. Two way radios are worn on the inside with microphones and ear speakers for a clear communications channel.

What is a Level B Hazmat Suit?
Offers a lesser level of protection that that of the Level A Suits.
Used when less skin protection is needed but a high respiratory protection is still needed dependent upon the substance type and atmospheric concentration thereof.
The suits are not vapor tight but do require a self-contained breathing apparatus (SCBA).
Dependent upon what suit is used, the self-contained breathing apparatus can be worn outside or inside the suits to help prevent the apparatus from becoming contaminated.
The suits are secured at face, hood, ankles, waist, and wrist to prevent the penetration of splash liquids.
Gloves and boots are also required to be worn with the Level B hazmat suits dependent upon the hazardous substance at hand that may be attached or non-attachable.
Two-way radio communication when using the garments is also required.
Also known as OSHA Level B Industry Standards.
What is a Level C Hazmat Suit?
Basically the same type of suits worn as a Level B.
The difference from the Level B protection is that different respiratory protection can be used other than only a self-contained breathing apparatus with the Level C suit.
A different variety of air-purifying respirator types can be included.
Should not be used unless the specific work function hazard can be measured and the actual substance is confirmed.
Can include coveralls or splash protection suits worn with a gas or respirator only.
Used when direct contact or liquid splashes will not adversely affect or be absorbed through any exposed skin.

The projected shelf life if the fabric materials is more than five years if it is not subjected to excessive heat or sunlight (>40C)
Dupont™ states that their garments contain materials which also include gloves for which no data is available for specific shelf life.
The garments may be used after passing a full visual inspection, and in the case of a vapor protective Level A suit must pass the ASTM F1052 Standard Test Method for Pressure Testing Vapor Protective Ensembles
