The Arboles UK range of emergency devices are designed to meet and exceed the current standards for EN (European), APPLUS (American) DIN, DVGW (German) and the much coveted ANSI. 

The ANSI standard that governs our realm of safety showers and eyewashes is the ANSI/ISEA Z358.1-2014 and we’ve created a brief guide that will help you when looking for your shower / eyewash solution. This is by no means an exhaustive guide, it is more of a bite size chunk to get you started. You can refer to the complete standard here for a full list of requirements.
