Provide tepid water over the thermostatic mixing connected upstream of the safety shower and eye wash units. In this case, both a warm and cold water supply is required.
- Adjustment range: 20 - 40° C (pre adjustment at 22° C)
- Scald protection: 43° C
- Warm water supply: 1“ male
- Cold water supply: 1“ male
- Flow rate: 60 litre/minute at 200 kPa dynamic water pressureThe supply of safety showers and eye wash stations with warm water is crucial. In accordance with DIN EN 15154-1: 2006 and DIN EN 15154-2:2006 a shower or flush period of at least 15 minutes is required to remove the contaminants to the largest extent possible. In fact, a shower or flush period of up to 60 minutes may become necessary in respect of extremely aggressive chemicals that penetrate deeply into the skin.
The extended exposure of the skin to cold water (below 15° C) can result in hypothermia. Please note that any water temperature below 32° C will result in a constant drop of body temperature. A particularly critical issue is the fact that water withdraws heat from the body 25 times faster than air. A human body can suffer from hypothermia within a matter of only a few minutes – the situation becomes critical if the body temperature drops below 32° C! Temperatures of more than 37°C have proven to be harmful to eyes and can intensify chemical reactions in the eye or on the skin. Medical recommendations state a tepid temperature – between 15º C and 37° C – as ideal for the treatment of tissues affected by chemical agents. Both DIN EN 15154-1:2006 and DIN EN 15154-2:2006 therefore recommend the supply of safety showers and eye wash stations with temperate water between 15º C and 37° C.
