Hazmat Suit Guide

Evolution of the Hazmat Suit

Be assured of your safety and security when a Hazmat suit is in place. Hazmat is an abbreviation for “hazardous materials”, otherwise known as dangerous goods.

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.

Make Your Own Hazmat Suit

If you plan to build your self a personal hazmat suit there are several considerations before you get started. First of these considerations is cost. You can purchase an actual Hazmat suit, the kind used by the US Government, for non vapor emergencies. The cost is well under $75. When you buy the items listed later in this article you may end up spending more than that.

The protective clothing items you will need for an effective Hazmat suit are as follow. This is the type of suit that does not have the enclosed hood. That piece of equipment is not something you can make on your own. With this suit if you encounter or expect to encounter hazardous airborne contaminants a gas mask or ventilator is needed.

Hazmat Approved Coverall

One specially laminated multi-layer coverall with hood that is not separate from the coveralls is required.
All the seams must sealed with sealed seams and storm flap. The storm flap is a front cover that is over the zipper to the coveralls. For a duty in hazardous conditions the zipper must be made of PVC plastic. That is because metal corrodes and disintegrates when exposed to some airborne chemical particles.

Hazardous Duty Gloves

For this hazardous duty protective clothing you must also provide complete protection for your hands and feet. For your hands that means having both inner and outer gloves. The joint between your coveralls and outer gloves is sealed with heavy duty anodized covering duct type tape. The seal is made by making two firm, but not tight, wraps with the tape in opposite directions around the joint. First you seal the inner gloves to the coveralls with the coveralls over he inner glove. Then you seal the outer gloves over the coveralls. This provides a double seal for protection when working in unknown or hazardous conditions.

Hazardous Duty Over Boots and Boot Liners

Your boot liners and over boots are sealed in the same manner as you sealed the inner and outer glove to the coveralls.

Goggles

You need a clear plastic wrap around type of heavy duty, impact resistant Goggles. Sometimes you can find these, new at Army or Government Surplus store sales. Some are available in tinted plastic to help shield the eyes in case of flash explosion events.

Protective Mouth Mask

A face mask that covers your nose and mouth, and is approved for hospital operating room use is required for all hazardous duty protective clothing suits. This protective mask can be easily pulled off if you need to apply a respirator or gas mask. These masks are available at any hospital supply outlet.

Gas Mask or Respirator

An approved gas mask or harnessed respirator system that would pass approval for use in hazardous conditions is rare to find in used condition. Once used more than a few times they are trashed because of possible seal leakage. If your suit is just for show, buy one at the nearest Army surplus store anytime.

Types of Protective Clothing

For those working in a number of vocations, protective clothing is a necessity in order for them to retain their safety. A hazmat suit has a long history of safeguarding hard working people. It not just protects your hands and face, which are the more sensitive parts of you, but conceals your entire body as well. There are various versions and levels of protection that these coveralls provide. They are meant to protect the wearer from both potential and very real danger ranging from toxic agents to high fire temperatures. The Hazmat suits used for Fire and high temperatures are typically the highest level suits and have the highest density, while the suits created for chemical danger are the lightest (though still provide great security.) They are classified by the degree of protection they provide, ranging from level A to level D.

Coveralls were used during WWII in order to protect from toxins and fire. The first Hazmat suit was created around 1940. It was entered from the front, had a waterproof zipper and was complete with a APR type respirator. Of course the functionality of this form of protective clothing was soon outdated. Up around the 1960′s they started being used for digging up hazardous material among other things and weren’t as safety regulated as they should have been. Problems surrounding the origin of hazmat suits were faulty material, sealing problems (cheap rubber gloves attached to the protective clothing using an elastic band was the best manufacturers could do at the time.) Hazmat suits have also been used for medical and scientific research where hazardous materials and chemicals were involved.

With all of the volatile resources and creations humanity has in it’s grasp, it’s no surprise that along with the advance of science and technology these coveralls have also evolved. Today’s protective clothing is much more efficient and useful in the way of keeping it’s wearing safe and sound. Not only has it increased it’s benefits, but coverall gear is used more today than at any other time in history. We have natural disasters, fires, oil spills, and laboratory accidents every year. Any one of these events can cause scenarios in which the use of a hazmat suit is key. Just last year, there was the immensely destructive tsunami in Japan, resulting in a catastrophic nuclear meltdown. Despite this tragedy workers were able to save lives and invaluable material, because of their protective hazmat suits. If you are considering acquiring any sort of coverall, it is important to look around and learn the facts of such an important piece of clothing/equipment. With this information you can be well on your way to purchasing the protective clothing you need to help you in your endeavors.
