Whether an emergency shower is needed in addition to an eyewash is dependent upon several factors, including what the Safety Data Sheet (SDS) says about eye vs. bodily injury. The need for one or the other is sometimes specified. Also, what is the possibility that the chemical could splash or spill onto the employee’s body vs. just the eyes? How much chemical are employees being exposed to, etc.? These are all questions employers need to ask during a hazard assessment. Based on the answers, an employer then must decide what the level of exposure and risk is, and provide the necessary protection accordingly.
