Safety showers are used to prevent accidents in the laboratory.
Any time a lab operator is doing some experiment, there might be some reaction from chemicals or ingredients which can be spilt across the laboratory and operator.
Whenever this situation arises, the operator quickly rushes to the safety showers and pulls the shower trigger, and water comes out from the head, spraying all over the operator.
Safety showers come in different materials, like M.S. and S.S. 304.
