Protective clothing functions

Ensure that protective clothing functions properly for its intended use.

Hepatic Effects. Liver function tests (serum bilirubin, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase) completed in 11 hexachloroethane workers who wore protective clothing were within the normal range (Selden et al. 1994). Mild skin and mucous membrane irritation were reported in the exposed group, suggesting that exposure may have been through either the inhalation or dermal routes of exposure.

Fully Encapsulating Suit (FES) Sometimes referred to as a Moon Suit, personal protective clothing diat provides complete skin, eye, and respiratory proteetion, and includes positive-pressure SCBA. The reader should refer to Chapter 2 for detailed discussions. Refer to Protective Materials. Fumes Solid particles formed by the condensation of vaporized solids, usually molten metals. Particles are much smaller than dusts with typical size ranges between 0.01 and 1.0 microns. Functional Group An atom or group of atoms, bound together chemically, that has an unpaired electron, which when it attaches itself to the hydrocarbon backbone, imparts special properties to the new compound thus formed. 

A third interesting aspect of this story is that Du Pont s aramide fiber was not specifically the result of market-driven research. When this fiber was patented in 1971 there was no commercial application in view. However, within ten years, three varieties of Kevlar fiber were commercialized by Du Pont for dozens of reinforced plastic applications in radial passenger tires, belts, in protective clothing, such as gloves or ballistic and flak vests, in ropes and cables in racing kayaks and canoes, and in commercial aircraft. Thus the Kevlar fiber by no means resulted from the functional, bottom-up, approach which is sometimes considered as a major characteristic of materials science. The aramide fiber resulted from the traditional style of industrial research which was successful in the plastic era and confirms the leadership of chemistry in materials technologies. 

Through these studies we have acquired considerable data on human exposure as well as experience in designing and conducting research to monitor real-life exposure of pesticide applicators. Exposure is relevant to human health only in relation to the dose taken into the body, its toxicity, and the rate of excretion. In our studies we have monitored no group nor individual whose dose approaches a level which could affect human health. Our studies have shown that exposure and dose are influenced materially by human attire and habits, type and function of equipment, and safety precautions such as protective clothing or washing soon after exposure to a concentrate. 

Modern coal mines work clothes is protective clothing with special function, can adapt to the coal mine complex work environment, to better protect miners life safety and health. Based on the important role of mining protective clothing in coal mine production, both at home and abroad in the mining design of protective clothing are of different levels of study. 

Coal mine working environment cause the hidden trouble of the combustion is more, and mean to operate near the melted metal (Gao et al. 2011). In addition, there are many flammable and explosive substances, in a flash fire accident in which has the function of flame retardant protective clothing, can protect the body from damage within a certain amount of time.
