Creating a Portable Eyewash Station

Abstract

Eyes are vital organs for human function. Activities involving chemicals or educational procedures, such as the use of paint strippers, may cause accidents or eye emergencies. Therefore, immediate eye irrigation is essential. Typically, facilities install fixed eyewash stations. This research aimed to create and evaluate the efficiency of a portable eyewash station unit. The design process began with creating an eyewash basin measuring 65 × 65 × 87 centimeters, manufactured from 304 stainless steel. Water pressure was provided by a DELTON DWP-12 submersible water pump, 12-volt model, powered by a 12-volt, 14-ampere dry battery. The water storage system consisted of two tanks with a total capacity of 20 liters: a white tank for clean water and a black tank for used water. The eyewash basin was manufactured from stainless steel, model CSZ-W1014, with a diameter of 270 millimeters, equipped with two eyewash heads. Water flow was controlled by a lever located on the right side. For mobility, the eyewash station was equipped with four 2-inch wheels and a wheel-locking system for stability during operation. Test results showed that the battery could operate for an average of 6.48 hours at 100% battery status. When battery status decreased to 25%, operational efficiency declined. The average battery charging time was 2.29 hours. Based on these results, it can be concluded that the portable eyewash station is suitable for practical use.
