Proper protective clothing is needed during every day in industrial, agricultural, medical work, during military operation and response to terrorism incident. Choices must be made as to which items of protective clothing to select for a given situation or environment. A number of variable to be consider ed include weight, comfort, level of protection and during of protection required. The protective clothing used in the World War I against chemical warfare agents (CWA) consisted of rubber clothing, which, together with gloves and boots, to cover the entire body apart from that protected by the mask. Clothing of this kind is usually characterized as impermeable. This means that CW agents cannot pass through the material and also the fact that perspiration released from the skin is also prevented from passing out. onsequently, to wear clothing of this kind for longer periods is extremely uncomfortable and in hot climates the period during which protective clothing of this kind can be worn will be very short. This review brings out a sequence related to the NBC protective clothing, their type, various materials available for the development of NBC clothing. An ideal protective cloth is the one that resists encountering with dangerous gases and steams. Another word, an ideal protective cloth is the one that has pregnability facing with water-steam and low impregnability encountering with different gases. In other to produce the above protective clothing, it is suitable to use polymeric membrane. The customary NBC clothing is based on foam thus is saturated with active carbon. A substantial portion of active carbon is contact to the foam which is not participated in absorption process. Carbon fiber demonstrates good physical stability and it can be used in NBC clothing instead of foam. All surface of carbon fiber participates in absorption of chemical agents. Simultaneous application of polymeric membranes and carbon fiber conforms and produce a clothing with high safety and high durability in contamination area.
