General Storage and Use
Materials that are extremely hazardous to property, health or the environment
(highly toxic gas, explosive, highly water reactive, and pyrophoric materials for example)
must not be procured until the necessary permits, administrative, engineering, and
environmental controls are in place.
Hazardous materials must be stored and used in accordance with numerous regulations
including, but not limited to, the International Fire Code and local amendments.
For laboratories, refer to your Chemical Hygiene Plan for standard operating procedures.
If you are interested
in the disposal of hazardous materials please see our information concerning waste. If you're looking for some general information about
frequently used hazardous chemicals please see our information concerning chemicals.
A Fire Department permit is required to store and use hazardous materials in
University buildings. Permits may be obtained directly from the Seattle Fire
Department (leaves EH&S Web site), or other appropriate local authority, through application to the Fire Marshal's Office Permit Section, or call 206.386.1450, or other appropriate local authority. (see here for more information). Departments are responsible for permit fees.
Permits are required for any quantity of highly hazardous material, and for
small to moderate quantities of other materials. (For example, a permit is
required for any quantity of highly toxic or unstable material, and for flammable liquids in quantities in
excess of five gallons in a building). Contact the Fire Department directly or EH&S Building and Fire Safety at (206) 543-0465
Rooms where hazardous materials are stored or used in quantities that exceed certain thresholds, and rooms
dedicated to storing hazardous materials are required to have a National Fire Protection Association (NFPA) diamond
sign on all doors. Most laboratories on the Seattle campus can print their own signs directly from their MyChem inventory. For information regarding lab signs visit www.ehs.washington.edu/fsohazmat/labsign. Call EH&S Building and Fire Safety at (206) 543-0465 for further information.
Inventories are necessary to verify that aggregate materials quantities within
buildings are in compliance with the International Fire Code (IFC). They are also necessary for Fire Department hazardous material
permits and for EH&S to produce required University Community Right-to Know reports. Departments
maintain hazardous material inventories and after-hours emergency phone numbers in MyChem. Primary investigators and other faculty and staff using hazardous materials must be
prepared to provide assistance to emergency services in the event of a hazardous spill, fire
or other emergency.
Brief Fire Code and Hazardous Material Overview
Flammable Liquids: The quantity of flammable liquids in a single laboratory stored outside of an approved flammable liquids cabinet must not exceed 10 gallons. All 10 gallons, unless in use, must be stored in approved containers
Peroxide Forming Chemicals: Peroxides
may form in some organic compounds by autoxidation. Peroxides can cause serious
accidents and, in some circumstances, become low power explosives that can be
set off by shock, sparks or other forms of ignition. Some organic compounds
form peroxides in a matter of months under the right circumstance. Be aware
of organic compounds in your lab and remember to mark the expiration date on
each container and review them periodically for disposal. Ether is an example
of a peroxide forming chemical. Click here obtain a Peroxide
Forming Compounds Assessment Guideline (PDF). For technical support, contact Chemical Waste at (206) 616-5835.
Pyrophoric Material: Pyrophoric material is a material that will spontaneously ignite when it comes into contact with air. This material is only permitted
in fire sprinkler protected laboratories in very small quantities (4 pounds aggregate per zone). Potassium metal is an example of a pyrophoric material. Extreme precaution is required when working with this type of material.
[Zones are defined by the buildings design and the building codes. In some cases an entire floor or multiple floors are considered one zone.]
Highly Toxic Material: Materials classified as highly toxic are only permitted in small quantities in University buildings
(Up to 10 pounds per zone). Highly toxic gas, like Arsine, is not allowed in any quantity without engineering controls and a special permit from the Seattle Fire Department.
Incompatible Materials: Incompatible materials are materials which, when in contact with each other, have the potential to react in a manner that generate heat, fumes, gases, or byproducts which are hazardous. For quantities of greater than 5 pounds or 1/2 gallon, separation by not less than 20 feet, approved cabinets, or a noncombustible partition is required. Smaller quantities should also be isolated
whenever practical. A common violation is flammable liquids stored with oxidizers.
