名校课堂系列答案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.
