Hughes STD-40K/45G Mobile 114 L Safety Shower with Eye Wash

The Hughes STD-40K/45G is a mobile, self-contained emergency shower with an eye wash, holding 114 litres of water on a wheeled steel frame for locations where a fixed shower is not available.

Emergency cover that can be wheeled to the job

The datasheet presents it as an addition for sites where a stationary shower and eye wash is unsuitable, for stand-by where no water supply exists, or when permanent showers are being maintained. The unheated unit has a polypropylene lined cylinder, a heavy duty powder coated mild steel frame and large pneumatic tyres, so it can be moved as the hazard moves during a project.

The shower starts with a hand lever and the eye wash when the lid is lifted. The 114 litre capacity gives a flow of 50 litres per minute for a little over 1 1/2 minutes, as printed, so it is a short-duration response while the casualty is moved to a fixed station, not a replacement for a 15 minute supply. Insulated and heated jacket versions, STD-J-40K/45G and STD-H-40K/45G, are listed for cold weather.

Technical specifications

How to deploy it on a shutdown or construction site

Treat it as supplementary cover. Hughes’ summaries of EN15154 and ANSI Z358.1-2014 describe fixed showers delivering 76 litres per minute for 15 minutes, which a 114 litre vessel cannot do, so the standards position for a mobile unit has to be agreed with the site safety officer. Its value is speed: it arrives at the work face with water already onboard, and a 1/2 inch quick release hose connector lets it be refilled from a hose at 3 to 5.5 bar g.

Station it where the route to the casualty is level and clear, mark it with a safety sign, keep the cylinder topped up, and add the weekly activation to the permit-to-work routine. Because the unit is unheated, water in the cylinder follows the weather; use the jacket versions where nights are cold, or empty and store the unit.

Options and what to confirm before ordering

The datasheet lists the insulated jacket, the heated jacket and a handheld eye, face and body shower as options. Confirm the refill hose source and its pressure, the ground the wheels will cross, whether hire is wanted in place of purchase (the manufacturer also lists the unit for hire), and the duration of cover the site safety plan requires.

How the Hughes STD-40K/45G works

The cylinder holds 114 litres of water on a wheeled frame. Pushing down the lever opens the stainless steel ball valve and the water flows from the shower nozzle. Pulling the lid down opens the eye wash. The water is fed by the tank, so no supply connection is needed to start the flow.

Where the STD-40K/45G is used

• Temporary work fronts
• Stand-by cover where no water supply exists

Installation, commissioning and maintenance notes for the STD-40K/45G

Place the unit where the crew can reach it quickly and keep the path clear. Fill the cylinder and check for leaks. Test the shower and the eye wash on a regular schedule and refill after every use. Keep the nozzle covers and the eye wash lid clean.
