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.
Also known as OSHA Level A Industry Standards.

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.
Not used or offer protection in an atmosphere that is deficient of oxygen.
Also known as OSHA Level C Industry Standards.

What is a Level D Hazmat Suit?

Protection from work clothing protection splash hazards from eyes.
An example would be a work uniform without any respiratory protection. 

What is the shelf life or storage life of the hazmat suits?

Shelf life for the Dupont™ Tychem® Garments

Dupont™ advises that garments that are no contaminated and are of more than five years old to be used as training purposes only.
There is not enough evidence to show the fabric of the Tychem® material loses physical properties or protective characteristics in a period of five years.
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

See this link more information on storage life of limited-use Garments 

Optimum Storage Conditions

The hazmat suits should be stored in an cool and dry dark environment that does not have exposure to insects and is free of dirt and dust particles.
The location should not have exposure to sunlight, high temperatures >120 degrees Fahrenheit , and exhaust fumes from motorized vehicles, under heavy weight of objects and objects that contain sharp edges or any projections that could be known to degrade the materials inside of the ensembles.
Other conditions and situations never to do include:
-Never step or walk on the garments
-Do not store or place objects that are heavy on top of the suits

Choosing a Hazmat Suit Guide

Search by Hazard

Hazard Select Tool IconOne of the several ways to search is to know the CAS (Chemical Abstract Service) number of the chemical compound you are dealing with. A CAS number can be up to 10 digits long, split into three parts, and divided by hyphens. One example of this is Ammonia which has a CAS number of 7664-41-7.

For a full list of CAS numbers see https://en.wikipedia.org/wiki/List_of_CAS_numbers_by_chemical_compound
Now let’s look up Ammonia using lookup by CAS number using the SafeSPEC™ tool by using the steps below:

1. At the selector home click on hazard.
2. Read the terms of use policy and hit agree if you agree to the terms provided.
3. Under “CAS Number” field enter the CAS number that corresponds with the chemical compound.
4. Click the “Add to List >” box.
5. Two options appear in a pop up box that says multiple hazards found, Ammonia (gas) and Ammonia (liquid, < -35°C).
6. Select liquid in this example to move on to the next box.
7. You will see it will give new information regarding that the hazard was tested as a liquid phase and to caution on what the working environment temperature is. For now click the x to exit out of the box in order to continue with the liquid only example.
8. Click next under the Hazard and CAS box where Ammonia (liquid, < -35°C) and 7664-41-7 was added.
9. The next screen will ask you a series of question regarding what type of hazard exposure you will be dealing with. For our Ammonia example check the following: No, Moderate, Spray, 15 minutes, and Direction of exposure from below. Read the “Note” and “Caution” data then click view matching products to continue.
10. At this point you can see which hazmat suits can be used for this chemical based on the information provided. For this example the Tychem® models CPF 3 Coveralls, TK, and ThermoPro hazmat suits are shown.
11. Next click the tab above that says “chemical resistance”, enter the CAS number once again in the blank fields, and then click on see all fabrics tested. This will show the hazmat suits materials breakthrough times for that given chemical element.

The second way of searching by hazard for a hazmat suit is in the box called “Chemical or Other Hazard Name.

1. Type in the chemical name, in the example for Ammonia type in the letters “Ammo”, a drop down box will appear where you can select from a selection of auto filled named for chemicals.
2. Select Ammonia (liquid, < -35°C) as an example, then select the “Add to List >”
3. As in the above example the dialogue box appears warning about the ambient temperature. For now close that box by click on the white x and hit the “Next >” button to continue on.
4. Repeat steps 9 through 11 as shown above and there you have it, another way to lookup the data for your hazmat suit research.

Search by Industry/Task

Another way to do a search lookup for hazmat suits is to use the SafeSPEC™ 2.0 tool and do a search by task/industry.

1. At the SafeSPEC™ 2.0 selector home screen select the industry tab.
2. As shown in the hazard example before read the terms and agreements and click agree if you accept the terms provided and wish to continue on.
3. A list of industries will appear on the page select on that best fits your description, for an example I will chose Waste Management (Remediation & Refuse)
4. The next screen shows types of tasks and refuse, for now I will chose Biohazard Handling to continue on.
5. Here is explains what will be evaluated as the hazard I picked or I have the option click to go back to the “Identify Your Hazards” page to enter more hazards by a chemical or hazard name or with a CAS number. It also includes a PDF about Bloodborne Pathogens if I want more information regarding that subject. Not all pages will be the same at this screen. For now we will click next to continue on with the example.
6. The next step is to enter in data for hazard exposure which is at the moment is Bodily fluids with potentially infectious diseases, CAS number unknown, and a physical state that is liquid. Enter random data here to continue on for example purposes only, select No, Moderate, Spray, and All Directions for Direction of exposure. Read the Note and Caution sections then click view matching products. Here you can see all the matching products based off the scenario provided. Hazmat suits such as Tyvek®, Tychem® QC, CPF3, BR, LV, TK, and ThermoPro appear as a result.
7. Also be sure to check out the Chemical Resistance Tab to find permeation data breakthrough time for particular chemicals challenges for a given Tychem® fabric.

Look up by Guide

The third and final way to find the right garment for your situation is to use the Guide feature. Basically it is like the tools described above but more questions can be asked and it offers more flexibility in the hazmat suit selection process. It is also used if the particular hazard cannot be found in the database.

1. Introduction – This section describes what the Guides functionality is.
2. Define your hazard – Evaluates one hazard at a time, asks a few questions about the hazards physical state, concentration, and time of exposure.
3. Define your exposure level – More questions are asked about the exposure risk regarding flame, contact quantity, duration, and direction.
4. Select Your Fabric – This is where a fabric can be selected for further review, and provides permeation data for all ASTM F1001 chemical challenges for the Tychem® fabrics based on the information provided earlier.
5. Seam Selection – Shows the seam options based on answer given from the hazard scenario questionnaire answered earlier. Allows the selection of seam or different seam options for further evaluation.
6. Design – Different design options can be chosen for the scenario provided for further consideration.
7. Matching products results page – Shows the actual products and their corresponding Tychem® product model numbers based on all criteria given from the previous steps.

My Scenarios

Scenario Select Tool Icon

The Scenarios tab is where you can find saved data from previous research and not have to go through each scenario with the selector tool again. It also has important reads about multiple scenarios or searching multiple hazards at one time, updates, and cache storage.
