In laboratories, accidental chemical exposures can still happen even when good engineering controls and safety protocols are taken into consideration. Emergency showers and eyewash stations provide on-the-spot decontamination to flush away hazardous substances that can cause injury. Walk around your lab and identify the locations of emergency eyewash and showers. Always keep these emergency safety equipment free from obstruction. Ask your PI or lab manager who is assigned to test your eyewash and safety shower regularly. The safety showers should be tested monthly and the eyewash stations weekly. A record log indicating who and when the showers and eyewash stations are tested should be placed in the vicinity of the stations.
Have a bucket available that is large enough for water catchment from these stations and check the clarity of the water. Clear water indicates a clean station. If the water is not clear, continue running water until it turns clear. A regularly tested station should have clear water come out of it
