Respiratory suits

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. 

Depending on scale of operation, use impervious rubber gloves, eye protection (glasses/goggles/face shield), rubber aprons, boots, armlets, protective suits Provide respiratory protection against gases/dusts/fumes Provide shower and eyewash facilities... 

Equipment may get washed with a steam jenny and allowed to air dry on plastic in a more remote area. We need to keep in mind that steam cleaners have the potential to cause substantial physical harm. The combination of high-pressure water and high temperatures can be dangerous. Wlien this is coupled with a worker standing on visquine or plastic, it becomes a slip, trip, and fall situation. Situations compounded with respiratory and whole-body protection, such as saranex or rubber suits and gloves, add in the potential for poor vision, heat stress, and the lack of physical dexterity. Keep these issues in mind prior to steam cleaner activity. 

Level A protection 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, coveralls, hard hat, and self-contained (positive pressure) and 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.). 

Fire Tabun reacts with steam and water to produce toxic and corrosive vapors. Any personnel not fighting a fire of sarin should immediately be evacuated from the area. 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 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. 

Fully Encapsulating Suit (FES) Sometimes referred to as a Moon Suit, personal protective clothing diat provides complete skin, eye, and respiratory proteetion, and includes positive-pressure SCBA. The reader should refer to Chapter 2 for detailed discussions. Refer to Protective Materials. Fumes Solid particles formed by the condensation of vaporized solids, usually molten metals. Particles are much smaller than dusts with typical size ranges between 0.01 and 1.0 microns. Functional Group An atom or group of atoms, bound together chemically, that has an unpaired electron, which when it attaches itself to the hydrocarbon backbone, imparts special properties to the new compound thus formed. 

The essential oil has many beneficial effects and applications in aromatherapy for skin and hair care, as an antirheumatic, antispasmodic and calmative, for complaints of the respiratory, circulatory and digestive systems and for nervous disorders. The camphor type is best suited to the musculoskeletal system, and the 1,8-cineole for pulmonary congestion and efficient functioning of the liver and kidneys, with the verbenone being a safe nonirritant essential oil for skin and hair treatments.
