Product Overview

This station pairs a full-body drench shower with a large-diameter stainless steel eyewash basin, and controls the eyewash with a linkage flip cover: the lid that keeps dust out of the bowl is connected to the valve, so lifting it uncovers the spray heads and starts the flush in one movement. That means the user does not have to find a separate push plate with wet or contaminated hands — the cover they are already reaching for is the actuator.

The column, shower arm, basin, lid and linkage are stainless steel, and the unit fixes to the floor through a bolted flange, so no platform or pit is needed.

How the Linkage Flip Cover Works

1. In standby the cover sits down over the basin. It keeps dust, swarf, paint overspray and splashes off the nozzles, which is the main cause of blocked eyewash heads on plant.

2. The user lifts the front edge of the cover. The cover is linked to the valve spindle, so as it swings up the valve opens and water begins to flow.

3. The cover stays open while flushing, giving an unobstructed bowl; the linkage can be set so that closing the cover shuts the water off again.

4. Because the movement is a single upward lift, the eyewash can be started with a forearm or the back of the hand if the palms are contaminated.

Key Features

• Large-diameter basin – a wide stainless bowl catches the flush from both heads and gives room for the face, so the user is not aiming at a small target while in pain.

• Flip cover as actuator – dust protection and valve operation combined in one part, reducing the number of things that can fail or be forgotten.

• Twin spray heads – two aerated nozzles angled upward flush both eyes together at low pressure, set under the cover so they stay clean.

• Pull-wire shower control – the overhead deluge head is opened by a stainless wire with a triangular handle; the stay-open valve keeps water running while clothing is removed.

• Bolted floor flange – a single stainless column on a floor flange, with pipework inside the column feeding both functions from one inlet.

• Assembled and flow tested – the linkage is set and the unit flow tested before packing, so commissioning is anchoring, connection and verification.

Technical Specifications

Operation

1. Reach the station within 10 seconds of the hazard and stand in front of the basin.

2. Lift the flip cover with a hand, or with the back of the hand or forearm if the palms are contaminated; the eyewash starts as the cover opens.

3. Put the eyes into the flow, hold the eyelids open with thumbs and forefingers and roll the eyes so water reaches every surface.

4. For body contamination, pull the triangular handle to start the deluge shower; the valve remains open until it is pushed back.

5. Flush for at least 15 minutes, removing contaminated clothing under the running water, then seek medical attention. Close the cover and the shower valve afterwards.

Installation and Commissioning

• Set the column on a level, load-bearing floor on the same level as the hazard, leaving clear approach space and no obstruction within the 10-second travel distance.

• Anchor through the floor flange with fixings suited to the floor, checking the column is plumb before final tightening.

• Flush the supply line, connect the 1-1/4 inch inlet and pressure test at 0.2 – 0.4 MPa; check the internal split to shower and eyewash.

• Lift and close the flip cover several times: the valve must open smoothly on lifting and shut off cleanly on closing, with no binding of the linkage.

• Verify shower and eyewash flow rates and, where the site requires tepid water, fit a thermostatic mixing valve upstream.

• Fix the identification sign at eye level and record the commissioning date and the linkage setting on the inspection tag.

Maintenance

• Weekly: lift the cover to confirm the eyewash starts, pull the shower wire, and check that both close fully.

• Monthly: clean the spray heads and the inside of the bowl; check the hinge, the linkage and the cover seal for wear or debris.

• Quarterly: inspect the valve spindle and linkage adjustment, and confirm the cover still sits flat when closed.

• Annually: measure flow rates, replace worn seals or nozzles, and re-tag the station.

Standards and Compliance

The station is designed to the performance requirements of ANSI Z358.1-2014 and EN 15154 for combination emergency shower and eyewash equipment, including hands-free activation of the eyewash, a stay-open shower valve, twin eyewash heads delivering a controlled low-pressure flush, and shower coverage of the whole body. The flip cover is an operating and dust-protection feature; the requirements for location, access, water temperature and 15-minute flushing still apply and should be verified at commissioning.

Applications

Chemical and pharmaceutical plants, university and industrial laboratories, paint and coating lines, machine shops where dust and swarf are present, food and beverage production, battery and semiconductor plants — anywhere an open eyewash bowl would collect debris between uses.

Ordering
