Chemical Safety
Procedures for handling chemical spills(泄露) and leaks.
Chemical spills and leaks can be broken down into two basic types: simple spills, which you can clean up yourself and complicated spills, which require outside assistance.
If your spill meets any of the following conditions, it is a complicated spill.
★ A person is injured; or
★ The identity of the chemical is unknown; or
★Multiple chemicals are involved; or
★The chemical is highly poisonous, flammable (可燃的) or reactive ; or
★The spill/leak occurs in a “public space” such as a corridor; or
★The spill/leak has the potential to spread to other parts of the building such as through the ventilation (通风) system; or
★The clean up procedures are not known or appropriate materials are not readily available; or
★The clean up requires a respirator (呼吸器) (including cartridge respirators) to be worn and no personnel have been trained and fit-tested in accordance(一致) with the campus Respiratory Protection Program; or
★The spill/leak may endanger the environment by reaching waterways or outside ground, or by going down a drain
If none of the above conditions are met, the spill is defined as a simple spill. You may clean up simple spills in accordance with Chapter 6 of the Chemical Safety Guide. For consultative assistance, call Division of Research Safety (DSR) at 333-2755.
How to report a complicated spill Evacuate(撤退) to a safe location, and alert others to evacuate. Dial 9-911 from a campus phone. Tell the operator you are calling to report a chemical spill at the University of Illinois. Have the following information ready. Name of chemical Quantity spilled Location of spill (Full building name and room number) Number of people injured or slashed If applicable, the occurrence of a fire or explosion Your name and phone number 5.
