Protection from Multiple Hazards

While some items of protective clothing are designed to protect from only one hazard, many others must solve multiple problems. A list of the modern battle-ready soldier's requirements for protection illustrates the complexity of multiple physical threats. Military documents point to a daunting list of hazards from which clothing must provide protection: climate (heat, cold, rain, solar radiation, wind, sand, snow); weapons (ballistics, chemical, biological, flame, blast, nuclear flash, directed energy such as microwaves); detection (visual, infrared); mechanical (cuts, abrasions, crushing); sensory (damage to hearing, sight); and biting insects and animals.

The great dilemma in designing for protection from multiple hazards is that there rarely is a clear-cut hierarchy of threats. Designing always involves trade-offs. For example, to protect soldiers from chemical weapons, they must be fully isolated from the environment. This necessitates the provision of breathing air and a method of preventing heat build-up within protective clothing. However, the motors used to circulate air leave a signal that can be picked up by infrared detection devices, providing the enemy with a target. Since both heat exhaustion and exposure to chemical agents could be fatal, neither of these requirements can simply be ignored to satisfy the need for full camouflage. Multifunction protective clothing for outer space, deep-sea diving, chemical-spill cleanup, Arctic exploration, asbestos removal, bomb disposal, race-car driving, mountain-climbing expeditions, and many other activities and environments all involve protection from multiple hazards. Even clothing that has only one primary protective function involves challenging trade-offs between protection, mobility, thermal comfort, and use of the senses.
