The Importance of Tepid Water - 1

The Importance of Tepid Water What is tepid water? Tepid water is controlled within a fixed temperature range. For EN standards this is stipulated as 15 to 37C (59 to 98F). The ANSI standard specifies 16 to 38C (60 to 100F). Why is tepid water important? Safety showers provide immediate relief for employees splashed with hazardous chemicals. The water, delivered at a minimum of 76 litres per minute for 15 minutes, washes the chemical from the skin and out of the eyes. A safety shower that operates outside of the tepid water range can cause more harm to a victim. A shower that is hotter than 38C can scald the injured person adding temperature burns to their injuries and increasing the chance of absorption of the chemical into the skin. Tepid water shower options Emergency Tank Showers with tepid water Emergency tank showers are ideal for areas where water supply pressure and flow are unreliable or where there is no constant water supply. The integrated tanks contain enough water to meet the 15-minute minimum specified by EN and ANSI standards. For hot climates, tank showers can be fitted with a cooling system to counteract solar radiation to ensure the water in the tank is kept to a tepid temperature. There are three different cooling options available: • Fitted with air-filter to prevent ingress of dust/sand Adversely, a person is likely to leave a cold shower that is below 16C before the recommended 15 minutes of decontamination is complete. This exposes them to ongoing chemical burns. A safety shower that is too cold may even induce hypothermia in a casualty.

The Importance of Tepid Water - 2

A specialized solution for frigid or Arctic climates is the Polar Tank Shower. Fiberglass panels and doors insulate the shower area. A room heater keeps the interior temperature at a comfortable level, ensuring a victim is not left out in the cold. Temperature Controlled Safety Showers A Temperature controlled emergency safety shower has its own water tank with heater. This hot water is then mixed with the a cold plumbed in supply via a thermostatic mixing valve to deliver tepid water on activation regardless of the ambient conditions. These units are designed to remain on standby to...
