Workplaces that use hazardous substances should provide adequate water stations to rinse contaminants in the event of an emergency. This is particularly important where you have teams that regularly handle these harmful substances as part of their day to day job.
This range of stations are specially made for rinsing the eyes, face or body in emergencies involving harmful substances. Therefore you should consider them as a form of first aid equipment. With this said, they are by no means a substitute for personal protective equipment or safety procedures. They are specifically for use as a result of an accident or emergency involving chemicals.
