Regular servicing and testing of Emergency Safety Showers and Eye/Facewash units is critical to ensuring proper functionality in the event of an emergency. Depending on the location and company procedures you may test daily or weekly and carry out servicing every 3, 6 or 12 months. Each time the equipment is tested or serviced in accordance with the agreed schedule, the person responsible dates and signs the tag. These attach to the safety equipment or an adjacent wall / object using pre-molded holes for zip ties or fasteners. Sold separately.
