Chemical protection suits

Chemical PPE In a fire or thermal energy hazard, PPE worn by responders should meet, at a minimum, the criteria in 29 CER 1910.156 (e), Eire Brigade Standard, requiring turnout gear. In conditions where skin absorption of a hazardous substance may result in substantial possibility of immediate death, serious illness, or injury or impaired ability to escape, totally encapsulated chemical protective suits should be used. It is vital to keep heat resistance of the totally encapsulated suits and the heat resistance of any PPE used underneath or in conjunction with the totally encapsulated suits in mind any time there is a thermal hazard.

Chemical Protective Suit A single or multi-piece garment constructed of chemical protective clothing materials designed and configured to protect the wearer s torso, head, arms, legs, hands, and feet. 

Fully Encapsulating Suits Chemical protective suits that are designed to offer full body protection, including SCBA, are gas tight, and meet the design criteria as outlined in NFPA Standard 1991. 

Evacuate danger area immediately Consult an expert Ventilation. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. NEVER direct water jet on liquid. Prevent from entering confined spaces. Do NOT let this chemical enter the environment (extra personal protection gas-tight chemical protection suit including self-contained breathing apparatus).

In case of personal protective fabrics, the bulk of ACF-based garments often results in thermal discomfort and physiological burden to the wearer. Therefore, it is necessary to create less bulky ACFs for enhanced physical comfort in chemical protective suits (Wilusz 2007). In order to achieve maximum protection and reasonable comfort, novel fabric ensembles with or without ACFs are necessary (Wilusz 2007 Gurudatt et al. 1997). An alternative approach to the use of ACFs for chemical protection is the use of functionalized selectively permeable membranes (Wilusz 2007). 

Dioxins and furans have been linked to cancer and other long-term health problems. To address these concerns, the Army (1) decided not to bum chemical protective suits, which could produce these types of emissions and (2) will measure possible dioxin, furan, and other emissions from incineration of mustard agent during upcoming operational verification tests. According to Army officials, this monitoring is not required by EPA.

In cases where respiratory devices are used to avoid exceeding occupational exposure limits, chemical protective suits are necessary. These are available for use against many different chemicals, and are made from various types of elastomer materials or coated fabrics. Most chemical protective suits enclose the whole body. In order to reduce any leaks, the protective boots are integrated. Normally one can choose from protective suits having fiiU face masks with a connector for a cartridge or an external compressed air breathing apparatus (Fig. 6.25 b), or with an...

All of the equipment listed in this section must be maintained properly, and a definite maintenance schedule must be established. For example, the integrity of the chemical protective suits must be verified on a 6-month schedule. A maintenance log must be kept in order to confirm that the maintenance program has been done on schedule. 

Protection from chemical agents has been accomplished on a regular basis by a variety of means, such as chemical protective suits that include face masks. However, biological enzymes can also be used as a counter-measure to chemical toxins.
