A requirement by OSHA First Alert Response guidelines states that, in the event of an incident the plant operator should be alerted of a running shower within 5 to 10 seconds of its activation. The shower indication can also serve to alert plant operations to bigger, potentially more significant problems in the remote areas of the plant. Many of remote safety showers in the plant were located in explosion-proof areas with no existing wiring. Which means, wireless technology would be one of the best available solution for safety shower monitoring. Emerson Smart Wireless Solution provides a quick fix solution by using the proximity switch and a wireless discrete transmitter. It alerts the control room immediately once it senses a pull at the safety shower.
Below link is one of our great reference we had done for safety shower monitoring.

In accordance with this OSHA guideline, I have customers who want to retrofit switches onto their existing safety shower and eye wash system, but do not know where to start. TopWorx has a ready solution with GO Switch and a universal mounting kit, which is applicable for most major brands of safety shower and eye wash. If there is no existing wiring, just add in a Rosemount 702 Wireless Discrete Transmitter, and the signal can be sent back to the control room wirelessly via. a gateway.

Safety and Eye Shower monitoring has indeed becoming a much discussed topic. I attended this workshop given by two users from Eqaute Petrochemical: Subramanian and Bala entitled "Wireless Instrumentation for Safety Showers and Cooling Tower Fans." They shared about how they have implemented monitoring of all their 114 eye and safety showers throughout their 04 process units with Wireless gateways. Operators in the control room will now be notified within 1 min should any safety or eye shower be used...All that without laying any signal cable...well almost there is the gateway to DCS modbu
