Decontamination Solutions to Avoid
Some decontamination solutions should be avoided because of their toxicity, flammability,
or harmful effects to the environment. Halogenated hydrocarbons, such as carbon
tetrachloride, should not be used because of their toxicity, possible incompatibility, and
some because of their flammability.
Organic decontamination solutions should not be used on Personal Protective Equipment
(PPE) because they may degrade the rubber or other materials comprising the PPE.
Mercurials are sometimes used for sterilization. They should be avoided because of their
toxicity.
Chemical leaching, polymerization, and halogen stripping should all be avoided because
of possible complications during decontamination.
Sand-blasting, a method of physical removal, should be avoided because the sand used
on the contaminated object usually needs to be disposed of as hazardous waste, a very
costly proposition. Also, sand-blasting exposes personnel to silica, a carcinogen.
Freon is known to be particularly effective for the cleansing of PCB's but its effect on the
ozone layer is extremely harmful. Its use is discouraged.
Strong acids or bases should not be used when cleaning metals and gaskets or tools or
other equipment because of the possibility of corrosion.
Disposal of Decontamination Solutions and Waste Water
All solutions and water used for decontamination must be collected. If lab analysis
indicates that the water and/or solutions exceed allowable contamination levels, they must
be treated as hazardous waste. Alternatively, the solutions and water may be treated on-
site to lower the contamination levels and render them non hazardous.
Containers such as 55 gallon (208 liter) drums should be available for storage of wastes.
Spent decontamination solutions can be collected by using heavy-duty plastic sheets,
visqueen sheets, kiddie pools, or if needed, a larger containment basin. The
decontamination of equipment must be performed on the sheets or in the basins. They
could be placed on a slight angle so that the spent decontamination solutions drain into a
collection basin or drum.
Recommended Supplies for Decontamination of Personnel, Clothing and
Equipment
The list below contains recommendations for supplies which would be on hand for the
decontamination of personnel, clothing and equipment. Depending on the site activities,
not all of these items may be needed. Alternatively, some additional items not listed here
may be required.

Drop cloths of plastic or other suitable material, such as visqueen, for heavily
contaminated equipment.
