Personal Protective Equipment Respiratory protection is required (positive pressure, full face piece, NIOSH-approved SCBA will be worn). When response personnel respond to handle rescue or reconnaissance, they will wear Level A protection that should be worn when the highest level of respiratory, skin, eye, and mucous membrane protection is needed. This level consists of a fully-encapsulated, vapor-tight, chemical-resistant suit, chemical-resistant boots with steel toe and shank, chemical-resistant inner/outer gloves (butyl rubber glove M3 and M4 Norton, chemical protective glove set), coveralls, hard hat, and self-contained (positive pressure) breathing apparatus (SCBA). 

Personal Protective Equipment Phosgene is a severe respiratory tract and skin irritant, and contact with the liquid will cause frostbite. Respiratory protection requires positive-pressure-demand, self-contained breathing apparatus (SCBA), while skin protection requires chemical-protective clothing since phosgene gas can cause skin irritation and burns. NIOSH recommends protective suits from Responder (Kappler Co.), Tychem 10000 TM (DuPont Co.) or Teflon (DuPont Co.). 

Personal protective equipment is clothing and/or respiratory equipment worn to protect the body against various forms of contamination. Some of the most common forms of personal protective equipment include dust masks, air purifying respirators, protective suits made from particulates or chemically resistant materials such as Tyvek (E.I. Du Pont de Nemours Company, Inc., Wilmington, DE) and/or other fabrics, and lightweight protective rubber gloves or chemical-resistant gloves. 

Personnel protective equipment may be used in certain circumstances where exposure to airborne particulates contaminated with chemical carcinogens could occur. In those situations, personnel should be equipped with a complete clothing change, as well as respiratory protection selected on the basis of work performed, type of chemical used, and containment equipment. The respiratory protection may be a face mask, respirator [selected from those approved by the National Institute for Occupational Safety and Health (NIOSH)] (4, 5), or emergency breathing air system. In the latter case, a head hood or a complete protective suit may be used with a breathing air supply system. Figure 2.

Level B is employed when the maximum level of respiratory protection is needed, but a lower form of skin protection is required. The chemicals have been identified. This lower form of dermal (skin) protection provides protection against liquid splash only. Level B lacks the totally impermeable protective seal that is seen with Level A. Environmental toxic vapors can come into contact with the skin when Level B is worn. Should a potential problem arise if toxic vapor were to come in contact with the skin. Level B should not be worn. This would necessitate an upgrade to Level A. Level B suits provide no skin protection from vapor exposure, nor any protection against continuous contact with liquids. All Level B suits are made of impermeable material. 

Replacement cartridges and filters come in a wide variety and should be matched to protect the worker from a particular contaminant. Reference information for selection and identification of air purifying canisters and cartridges can be found in 29 CFR 1910.134, Respiratory Protection. This color coding and labeling system enables users to select cartridges which are best suited for a particular contaminant. The basic color coding system is shown in Table 4-2. 

PERSONAL PROTECTION wear full protective clothing (suits, gloves, footwear, headgear, etc.) wear chemical safety goggles and faee shield full facepiece respiratory protection is recommended eye wash fountains should be provided in the immediate work area.. 

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... 

Respiratory suits are protective suits which combine the function of a respirator. The breathing air is suppHed either by a compressed air line or a compressed air canister which is carried on the body. FuU-body suits already have been discussed in Section 6.8.3. Figure 6.26 shows the most important types. 

Level B is used when full respiratory protection is required but danger to the skin from vapor is less. It differs from Level A in that it incorporates a nonecapsulating, splash-protective, chemical-resistant suit (splash suit) that provides Level A protection against liquids, but is not airtight. 

B Pressure-demand full facepiece SCBA or pressure-demand supplied-air respirator with escape SCBA Chemically-resistant clothing, such as one-piece disposable suit or overalls and long-sleeved jackets The same level of respiratory protection but less skin protection...
