RY-DT-02 Modular Inflatable Decontamination Shower Tunnel with Roll-Up Flap Panels and Clear Windows

Product Overview

The RY-DT-02 is an inflatable decontamination shower bay built as a walk-through tunnel rather than a single-entry booth. A grey inflatable tube frame forms rectangular bays clad in orange PVC-coated liner, with an opening at each end, roll-up flap panels held on a retaining bar, clear PVC inspection windows in the side and flap panels, and a dark floor sheet running through the bays. The bays are designed to be linked end to end, so a single unit can be used as a shower bay or several can be joined into a sequence — undress, shower, redress — without a gap between them.

Why Walk-Through Beats a Single Booth — and What It Demands

Decontamination is a sequence, not an event. A person arrives contaminated, removes clothing, is showered, is checked, and is dressed again in something clean. A single-entry booth forces that sequence through one opening: the same door used going in is used coming out, and the clean side is whatever is outside. A walk-through tunnel lets the flow run in one direction, which is the whole point of the design, and the ability to link bays means the undress, shower and redress stages can be physically separated without moving people across open ground.

That advantage only exists if the flow is actually run in one direction. A through-tunnel has no second door to control contamination: if people enter from both ends, or if someone walks back against the flow to fetch a colleague, contaminated water and clothing travel into the clean end and the separation is gone. So the tunnel needs a marshal at the entry, a marked dirty end and clean end, and a briefing that nobody moves backwards. A tunnel without traffic control is just a longer tent.

The clear windows solve the visibility problem that closed liners create — the person inside can be watched without opening a flap — but they cut both ways. Windows on the dirty side will be splashed and will need wiping to stay useful, and a window facing a public walkway takes away the privacy the tent was put up to provide. Position matters: windows should face the marshal, not the crowd.

The modular joints are the next weak point. Two bays joined end to end have a seam at the floor, and water travels along the floor rather than over the seam. The floor sheet has to run continuously, the dirty end needs a sump or a collection point, and the joint needs to be checked after every deployment rather than assumed.

And the constant: this is an enclosure. It supplies no water, no heat and no disposal, and it is not an eyewash or a safety shower. Those remain separate requirements.

Key Features

• Walk-through tunnel configuration with an opening at each end, so decontamination can run one way.

• Bays interconnect end to end to form undress, shower and redress stages as one chain.

• Orange PVC-coated liner for high visibility at night and against smoke or dust.

• Roll-up flap panels on a retaining bar, so the openings stay clear during use and close for privacy or weather.

• Clear PVC inspection windows in side and flap panels, allowing the occupant to be watched without opening the tent.

• Grey inflatable tube frame with rectangular bays, erected with a pump and no tools.

• Dark floor sheet running continuously through the bays to contain run-off.

• Valves at the base with pressure relief, so the frame can be topped up in service.

• Packs down folded; the frame is the structure and the packaging at once, with no poles to lose.

Technical Specifications

Deployment and Commissioning

1. Lay out the chain on level ground and decide the flow direction before inflating: dirty end upwind and downstream of the clean end wherever the site allows.

2. Join the bays, checking that the floor sheet runs continuously across each joint with no gap or step.

3. Inflate the frame in stages, confirm the bays rise evenly, then anchor the corners or ballast them; an inflatable tunnel is light and will move once wet.

4. Set the run-off arrangement at the dirty end — sump, tank or lined pit and pump — before any water is used.

5. Run the water supply and heater or mixing unit and confirm tepid temperature at the shower head inside the bay.

6. Position the roll-up panels and windows, brief the marshal on one-way flow, and confirm that the occupant can be seen from the marshal's position without opening a flap.

Operation and Maintenance

After every deployment: decontaminate and hose down the liner, wipe the windows, dry fully before folding, and inspect the floor sheet and bay joints for tears.

Monthly while in service: inflate and leave standing for several hours to check for pressure loss; check valves, relief and the retaining bars on the roll-up panels.

Before each deployment: confirm the pump, repair kit, pegs, ballast and window cleaning cloth are in the pack.

Annually: inspect the liner for UV degradation and seam separation, check the clear windows for clouding, and replace the tent when the coating has hardened or the seams lift.

Standards and Compliance

The tent is an enclosure and is not a certified emergency shower or eyewash; it does not meet ANSI Z358.1-2014 and cannot be substituted for a flushing unit. Tepid water at 20–37 °C, fifteen minutes of flushing and a location within ten seconds of the hazard remain requirements of the shower, not of the tent. Run-off from decontamination is hazardous waste and must be collected and disposed of under the site's environmental permit. Where the contaminant is a gas or vapour, entry requires breathing protection and ventilation, and the tent must not be treated as a safe refuge. Fabric compatibility must be checked against the substances handled on site, and the one-way flow arrangement must be written into the site's decontamination procedure rather than left to the marshal's judgement on the day.

Applications

Chemical spill and leak response, tanker and rail incidents, fire and rescue decontamination corridors, industrial sites running a multi-stage decon procedure, and event medical cover where casualties may need undress, shower and redress in sequence.

Ordering

State the model RY-DT-02, the number of bays required and whether they are to be supplied as a linked chain, the footprint of each bay, the number and position of windows, and the pump type. Confirm how run-off will be collected at the dirty end and whether a sump or tank is to be supplied with the tent. State the chemicals the liner will meet so compatibility can be checked, and specify the flushing unit separately — the tunnel does not replace one.
