Thedeleterious effects of these chemicals can range from acute trauma, such as dermatitis or burns, tochronic degenerative disease, such

Since engineering controls maynot eliminate all possible exposures, attention is often given to reducing the potential for direct skincontact through the use of protective clothing that resists degradation, penetration, and permeation.Chemical-protective ensembles ra

Few standards, if any, apply to the design andmanufacture of chemical-protective ensembles.Additionally, protective clothing designs vary depend-ing on different end use applications in industrial settin

As a consequence, users are faced with a variety of commercial products andgenerally depend on manufacturer sales information to decide which protective clothing is appropriatefor their own application.

Generally, as the risks forexposure to chemical, biological, thermal, physical, and other hazards increase, it becomesincreasingly important that the ensemble provide consistent and overall perform

Summary of Practices4.1 In Option A, the durability of the chemical-protective ensembles and ensemble components are evaluated by subjecting theprotective ensemble to a manned exercise scenario. The suit

45、is inspected prior to and after the series of exercises to assess anychanges in the garments integrity.4.1 In Option B, the function of the chemical-protective ensemble and ensemble components are evaluated by observing theability of a test subject to perform routine work tasks while wearing the pro

46、tective ensemble. As in Procedure A, the suit isinspected prior to and after the series of tasks to assess changes in the garments integrity. Two options are provided for evaluatingF1154 183the comfort, fit, function, and durability of protective ensembles and ensemble elements using a test subject.
