About this serviceEast Texas
An emergency shower is a fixture that has to work perfectly on the one day it is used, having sat untouched for years. Almost every one we are called to inspect fails on the same two points, and neither of them is the shower head.

The requirement is a fifteen minute flush at a temperature a person can stand still under. Both halves of that catch people out.
Cold water fails the requirement. A blast of cold water in January drives people out from under the shower in thirty seconds, which means the injury is not being flushed. Shock and hypothermia are real risks on a fifteen minute flush.
Hot water is worse. It accelerates chemical absorption and it can scald. The temperature band is narrow and it is specified for good reason.
Tepid means a mixing arrangement built for the job. A thermostatic valve rated for emergency fixtures, which fails to cold rather than to hot if it loses one supply. An ordinary domestic mixing valve is not the same device.
Fifteen minutes of continuous flow is a lot of water. A shower and an eyewash running together need real supply capacity, and the pipe feeding them has to carry that without starving. This is where undersized installations show up.
Somewhere for the water to go. Fifteen minutes on a shop floor with no drainage produces a flood and a hazard of its own. Not every installation needs a drain, but every installation needs somebody to have thought about it.
The second common failure is nothing to do with plumbing performance and everything to do with where the unit is and whether anyone has touched it.
It has to be reachable in seconds, on the same level, without a door. A person who cannot see is not going to navigate a corridor or a stair. Around a corner or behind a pallet stack is the same as not having one.
Things get stacked in front of them. This is the single most common finding in a working building, and it happens within weeks of any reorganisation of the floor.
Weekly activation is not optional. Running each unit briefly every week clears stagnant water from the branch and proves it works. It also keeps the valve free rather than seized.
Stagnant water in a dead leg is its own hazard. A branch that only flows in an emergency holds warm, still water. Weekly flushing is what keeps that from being a second problem on top of the first.
Keep the records. Weekly activation, annual inspection, temperature checks. In an incident, that log is what shows the fixture was maintained.
Tell us how many units you have, whether they are fed with tempered water, and when they were last tested properly. Those three answers tell us most of what an inspection will find.
Corrigan, Livingston, Diboll and the surrounding parts of Polk County are on our round. We fit thermostatic protection built for emergency fixtures rather than domestic valves, we check flow and temperature together, and we leave you a test log that means something.
FAQ
Because the flush lasts fifteen minutes. Cold water drives people out from under it in seconds, so the injury never gets properly flushed, and hot water accelerates absorption and can scald.
No. Emergency fixtures need a thermostatic valve built for the duty, which fails to cold rather than to hot if it loses a supply. A domestic valve does not behave that way.
More than most people plan for. A shower and eyewash running together for fifteen minutes is a serious continuous draw, and the branch feeding them has to carry it without starving other fixtures.
Not always, but somebody has to have thought about where fifteen minutes of water will go. On a shop floor with no drainage it creates a flood and a slip hazard during an emergency.
Activated briefly every week, with an annual inspection. Weekly running proves the valve is free and clears the stagnant water sitting in a branch that never otherwise flows.
Something stacked in front of the unit. It happens within weeks of any change to the floor layout, and a station that cannot be reached blind in seconds is not doing its job.
