Protective Clothing For Building Inspections
Purpose: 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.

Examples of Typical Coveralls

Breathable fabrics reduce heat stress; “Tyvek” better for chemical protection.
Slide55
Protective Clothing
Non-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.
Slide66
Protective Clothing
Protective 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.
Slide77
Protective Clothing
Disposable 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.
Slide88
Other Protective Equipment
Disposable 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.
Slide99
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
Slide1010
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.
Slide1111
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.

Prior to Entering the Clean Room
Ask 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 clothingRespiratorDuct tapeExtra plastic bags
Spray bottle
Disposable towels
Flashlight
Camera
Slide1414
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 cameraFacilitates decontamination
Slide1515
In the Clean Room
Putting Protective Clothing OnAll 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.
Slide1616
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.
Slide1717
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!
