Emergency shower and eyewash stations are used as a form of emergency first aid and are directed at limiting the effects of accidental exposure to harmful materials. These pieces of equipment can be found in the majority of laboratories throughout campus. It is paramount for all laboratory staff to be familiar with the location(s) and proper use of this equipment.
There are five different types of safety equipment as depicted below
- Safety shower – Primarily located in hallways and near the entrances of laboratories.
- Eyewash stations – Typically located below the safety shower or near sinks.
- Drench hoses – Also located adjacent to laboratory sinks, they are similar to eyewashes but are connected to a hose instead of being stationary.
- Bullets – Connected to the faucets of sinks, these use the water supplied from the faucet for flushing power (Note: Bullets require the faucet to be turned ON in order for water to come out).
- Spray bottles – Located on the walls near the entrance of a laboratory. They are a one-time use bottle to spray the affected area if there is no other safety equipment nearby.
A safety shower should be used when any amount of corrosive materials comes in contact with the skin no matter how small the amount. The eyewash station should be used when dust, irritants, or chemicals enter the eye. Each type of safety equipment is operated differently but all follow a similar process. The switch, lever, handle, or paddle must be pushed or pulled to start the flow of water, and the reverse action must be performed to stop the flow. Following accidental exposure it is important to note that the safety shower or eyewash should be used for at least 15 minutes to ensure the adequate removal of harmful chemicals.
