Abstract

A rescue device for treating leakage of dangerous chemical includes a first container having a closed negative pressure chamber and an intake which allows outside dangerous chemicals to enter the first container and a second container installed and fixed in the first container. The second container contains a substantially harmless liquefied gas and has an opening which controllably communicates with the external environment. When the dangerous chemicals are leaking, the rescue device can be used to reduce the loss of dangerous chemical, alleviate the harm to the environment and human, and avoid the possible disastrous consequences.
