Ranking for protective suits
There is ranking given to these suits on the basis of protection they provide. These suits are classified by some specific methods. Like in Europe, these suits are ranked as one to six. Type one provides the highest level of protection and type six provides the least protection. However, in the United States, they are graded as A to D. Level A provides maximum amount of protection and level D provides the minimum. The suits of each level are proper for the different work which involves hazardous material.
Different kind of Hazmat gear or suitsare now available in the market which gives varying stage of protection and that depends upon the material that is being used. There are two types of protection, type one and type two. Suits of type one are extremely suppression suits and gives high level of protection from all types of chemicals like solids, liquids, and vapors or gas. Type two suits are not made airtight. Thus, they provide strong protection against liquids and solids. No protection is provided by them against gases or vapors. These suits gives extreme protection to well trained firefighters so that they could deal with toxic and caustic substances. Normal turnout suits don’t provide so much protection. Hazmat clothing’s are not made against explosion or fire. Well in that case, “flash” protection is used.
When type one protection is worn, the condition inside the suit is 11-17 degrees Celsius and contains 100% humidity. Because of such reasons, medical monitoring is necessarily required before and after using these suits.
