Asbestos NESHAPInspection and SafetyProcedures Course Chapter 12Protective Clothing 2014
2 Protective Clothing For Building InspectionsPurpose: keep off gross contamination from suspect ACM, debris and ACWM. Required when entering negative pressure enclosures and other containments. May be necessary in crawl spaces, mechanical rooms and where significantly damaged materials are present.
3 Personal Protective Equipment (PPE)Respirator Safety Glasses Disposable Clothing Others Hearing protection, gloves, safety shoes and hard hats as needed. Always be sure to know what is required on the site where you’re working. Commercial/industrial sites may have very specific safety requirements.
4 Examples of Typical Coveralls Tyvek ® Coverall Non-breathable fabric Kleenguard ® Coverall Breathable fabric Notice attached foot and head covers Breathable fabrics reduce heat stress; “Tyvek” better for chemical protection.
5 Protective ClothingNon-breathable fabrics such as Tyvek ® are very useful for splash protection when working with chemicals… but they are extremely hot to wear in the warm weather months, increasing the potential for heat stress . Breathable fabrics such as Kleenguard ® feel more like natural fabric to the skin and feel cooler to the wearer. Because of the heat stress issue it is recommended that breathable fabrics be chosen provided that chemical protection is not necessary.
6 Protective ClothingProtective clothing does not include street clothing!! This means when entering an asbestos containment: No T-shirts, blue jeans, socks or undergarments. It is best to use either disposable undergarments (such as Tyvek, etc.) or nylon bathing suits. Nylon bathing suits can be easily cleaned while decontaminating.
7 Protective ClothingDisposable protective garments do not keep you “asbestos free.” They are to keep gross debris off the body and not allow contamination to be transported out of the work area. Even when you seal closures (neck, wrists) with tape, there is no guarantee that asbestos will not get on the clothing underneath. Any street clothing that is worn into an asbestos work area can become contaminated. For demo sites or other non-contained inspection areas (where no decon is available) 2 protective garments are often worn over street clothing.
8 Other Protective EquipmentDisposable latex or polyethylene gloves are commonly used by inspectors.Inexpensive, disposable cotton gloves are also sufficient unless there are cutting, puncture or abrasion hazards to the hands. Then leather palm-type gloves or Kevlar would be required. If they are brought into containment or otherwise contaminated, they must be properly disposed of.
9 Other Protective Equipment, cont. Boots - Use inexpensive rubber boots over the suit foot coverings. They can be cleaned and reused between inspections. Steel toes as required! Hardhats as required by OSHA for hazards from falling objects. Safety glasses Hearing protection
10 GlovesIf contaminated, they must be disposed of! Simple cotton work gloves work in many situations and are inexpensive. Grip-type cotton gloves may be appropriate as well. Leather palm gloves for puncture & abrasion protection. Kevlar Gloves For Slice/Cut Protection. Latex or polyethylene gloves work well in most situations.
11 Protective Footwear Basic rubber or PVC boots are economical and can be reused after cleaning. “The employer shall ensure that each affected employee uses protective footwear when working in areas where there is a danger of foot injuries due to falling or rolling objects, or objects piercing the sole, and where such employee's feet are exposed to electrical hazards.” 1910.136 Rubber boots with steel toes and shanks are an OSHA and often a facility owner safety requirement.
12 Entering/Exiting Site with Three-Stage Decontamination System Clean Room Shower Equipment Room (Dirty Room) Load Out Room Wash Down Room Air Flow Air Flow Work Area Shower Water Filtration Unit Worker Decon Unit Waste Load Out Unit For waste bags, etc. Orange denotes contaminated area Airlock 3-5 ’ Airlock 3-5 ’ Poly Door Flaps
13 Prior to Entering the Clean RoomAsk the site operator for permission to dispose of any ACWM that might be created during the inspection. Examine your respirator thoroughly. Make sure all materials are assembled to conduct the inspection safely: Protective clothing Respirator Duct tape Extra plastic bags Spray bottle Disposable towels Flashlight Camera
14 Prior to Entering the Clean Room, cont. All Materials carried into the contaminated area should be sealed in plastic bags to minimize contamination. If a non-waterproof camera is used, seal it in an impermeable clear camera box. Protects the camera Facilitates decontamination
15 In the Clean Room Putting Protective Clothing On All street clothes are removed and stored in a clean area (often decon clean room). Be sure to leave all valuables in a locked location (your car!)… this includes wallets, rings, watches or other jewelry. Jewelry items can become contaminated! Nylon swim suit is put on. Disposable coveralls are put on. Ankles are taped as needed to reduce chances of tripping. If sleeve ends are loose, tape these to assist in minimizing body contamination.
16 Taping the Coveralls Tape Ankles to Prevent Tripping Tape on crotch area helps prevent tearing. Tape on sleeves keeps gross debris out of the suit while inspecting.
17 In the Clean Room, cont. Wear disposable, reinforced or steel-shank/steel-toe or washable rubber boots over coveralls. If boots will be worn elsewhere, use rubber (or equivalent) covers. NEVER use disposable coverall booties as the only foot covering!
18 In the Clean Room, cont.Respiratory protection is inspected, put on and +/- fit checked. Hood is put OVER the respirator straps. Don disposable gloves. Use tape to seal them to the coveralls.
19 In the Clean Room, cont. Proceed to the shower area; leave disposable towels (sealed in a plastic bag), an extra plastic bag and soap near the shower. Proceed through the equipment room to the contaminated area and conduct the inspection.
20 Before Leaving the Contaminated AreaWhile standing near the exit, HEPA vacuum (if possible) and wet wipe all: Areas of the protective coveralls Boots Gloves Sample containers Sampling equipment Proceed to the equipment room
21 In the Equipment RoomDecontaminate, as much as possible, all non-disposable equipment including footwear.Rubber footwear can be decontaminated in the shower. If decontamination is not possible, seal all non-disposable materials in a plastic bag to decontaminate later. While still wearing the respirator, carefully remove the outer boots or booties and gloves and remove coveralls. Roll the coveralls inside out while removing.
22 In the Equipment Room, cont.If a PAPR is worn, remove the belt that supports the battery and hold the unit while removing coveralls. Place all disposable protective clothing in a proper waste disposal container. Place non-disposable items in the shower. Wearing only the respirator and bathing suit, proceed to the shower.
23 In the Equipment Room, cont. Used Suits, etc. put In waste bag Enter shower with only respirator & swimsuit
24 In the Shower AreaWhile keeping the respirator as dry as possible, clean non-disposable items and place them in the clean room. Do not step out of the shower! Thoroughly wet the entire body. Remove respirator and soak filters and dispose of as asbestos-containing waste.
25 In the Shower Area, cont. Clean the respirator and place it in the clean room. Remove and thoroughly rinse bathing suit. Put it in a plastic bag and place in the clean room. Finish showering, thoroughly washing the entire body with soap and water. Proceed to the clean room.
26 In the Clean Room Dry off and dress in street clothes. If available and permitted, place all disposables (including used towels) in a labeled asbestos waste bag. Otherwise, place disposables in a labeled plastic bag and remove for proper disposal.
