The European standards, BS EN15154 and the international standard for safety showers and eye/face wash equipment, ANSI Z358.1-2014 specify that water delvered by an emergency safety shower must be tepid and is vital to ensuring worker safety.
What is tepid water?
Tepid water is controlled within a fixed temperature range. For EN standards this is stipulated as 15 to 37°C (59 to 98°F). The ANSI standard specifies 16 to 38°C (60 to 100°F).
Why is tepid water important?
Safety showers provide immediate relief for employees splashed with hazardous chemicals. The water 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 hot shower can scald the injured person adding temperature burns to their injuries and increasing the chance of chemical absorption. On the other hand, a person is likely to leave a cold shower before the recommended 15 minutes of decontamination is complete. This exposes them to ongoing chemical burns and may even induce hypothermia.
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 in the ANSI and EN standards.
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.
Indoor and Outdoor showers
Self-draining Showers and chiller units
In extremely hot climates, Self-Draining Showers and chiller units keep the water temperature in the tepid range.
Temperature Controlled Safety Showers
Ideal for outdoor use, a Temperature Controlled Emergency Safety Shower has its own water tank with heater. It delivers tepid water on activation regardless of the ambient conditions.
These units are designed to remain on standby to deliver warm water for over 15 minutes, conforming to European and ANSI standards. The showers in this range have an integral heated water tank which can also be used as a warm water source to feed other emergency shower units in the local vicinity.
