The Hazmat suit ensures your protection from hazardous wastes and materials, and other harmful substances from head to toe. With a breathing apparatus combined, it is very useful in areas contaminated by chemical spills, fumigation processes and other specialists needing to clean up facilities in environments exposed to radiation and toxic substances. Often confused with a military suit, the Hazmat suit can also applied in areas where temperatures and other elements in the environment are unbalanced.

One interesting note of the Hazmat suit is that it is frequently confused with the NBC or nuclear, biological and chemical suit of the military, usually used in combat.

The Hazmat suit can be classified according to four levels, with Level A providing the highest possible protection from harmful substances and wastes, ensuring that the suit does not have any leaks and is equipped with the appropriate breathing apparatus. To complete the suit, appropriate boots and chemical resistant gloves provide additional protection, with a two-way radio integrated inside the suit for monitoring operations and clear communication. The Level B category breathing apparatus is worn on the outside and may not be vapour-protective. Wrists, ankles and hoods are protected to prevent liquids from splashing. Gloves and radio are also required. In the Level C suit, the same type of garment in Level B is used, but the protection in an oxygen-deficient atmosphere is not the same as of Level B. Level D protection does not ensure from chemical exposure. This scale is widely used in the United States.

The suit must undergo a decontamination process before the user exits the suit and it is put away.

Over the years, the Hazmat suit has been redesigned to test its durability in certain environments. Some manufacturers have shifted to using plastic in the suits; however, some users still opt to use the ones made from rubber.

Hazmat in fiction is widely used, especially in science fiction to dramatize the situation of how environments are affected and the possible dangerous results it will have among humans and their neighborhoods. Some scenes and plots include having to face the challenge of neutralizing the area and cleaning up in big volumes.

The MSA rubber suit was usually in all black rubber, with flaps falling just below the shoulders, and a APR respirator attached in the front on the chest, which was a standard at the time. In the 1960s, Hazmat suits were not yet gas tight, paired with a full-faced mask with two gas-mask eyes, making it look quite scary. It has somehow made a regular appearance in some horror and suspense films over the years.

Lately, scientists and its developers have observed more ways to have protective and durable Hazmat suits. It is worth the investment and effort to be able to protect the human body from any toxic substances and other harmful materials out there.
