Waste Policies and Procedures Manual - 2003 Edition
This manual was prepared
for use within ISU. It is intended for use by, and applies to, ISU
employees, staff, visitors, and students. If this manual or any portion
of it is used elsewhere, neither its authors nor the University accept
responsibility for its contents.
8.0 EXCEPTIONS TO
NORMAL STORAGE AND REMOVAL OF HAZARDOUS WASTES
8.1 Peroxides and
Peroxide Forming Material
These two classes of materials are found extensively on the ISU campus,
and represent a risk to those who either use them or work in the vicinity
of someone who does. Peroxide forming materials present a danger
of explosion and fire caused by shock-sensitivity of the peroxide compounds
which can form inside a container. These compounds generally have
expiration dates beyond which they must not be used, but rather are to
be declared hazardous waste and replaced if necessary. The expiration
date may be assigned and printed on the container by the manufacturer,
or may be related to when the container was first opened. If two
dates are possible, the more conservative date should be used for safety
reasons. Appendix G contains a listing of some of these hazardous
materials found at ISU.
Some materials are either shock-sensitive when bought, or more likely,
become more shock-sensitive as they become older. A partial list
of these important materials is given in Appendix H. Be sure to read
and follow the label instructions for storage of these materials.
If you discover a shock-sensitive material, do not attempt to move it yourself.
Instead, notify the TSO immediately, and attempt to keep others from handling
8.3 Water Reactive
materials react with water to produce a variety of hazards, such as heat,
gases, fire, or corrosion. A partial list of these materials is given in
Appendix I. Be aware of what these materials are and notify TSO personnel
when they are declared waste. Special precautions are required to
safely store these materials.
Some compounds react spontaneously with air, moisture, or other compounds
in the air to cause danger to those who either use them or are in the vicinity
of those who do. A partial list of such compounds can be found in
Appendix J. Be aware of what these materials are and notify TSO personnel
when they are declared waste.
8.5 Cylindered Gases
Pressurized gas cylinders present potential hazards of several types.
First, some gases are under tremendous pressure and their accidental release
can cause a gas bottle to become a deadly projectile that can penetrate
a wall or kill a human being on impact. Second, the contents of bottles
themselves may be toxic and should not be released unless in use under
a fume hood or other exhausting device. Finally, valves can become
corroded with age and leak or disintegrate unexpectedly, causing the potential
for serious damage to people and property. If you are unsure about
a gas cylinder, no matter what its contents or pressure, contact TSO personnel
8.6 Suspected Carcinogen,
Mutagen, and Teratogen
There are some materials on the ISU campus that have no immediate (acute)
effects on human health, but present long term (chronic) risk. Material
Safety Data Sheets should indicate if a material is a suspected carcinogen,
mutagen, or teratogen. Special care should be used when handling
these materials. You can contact the TSO personnel for assistance.
