General Considerations
When planning the installation of emergency safety showers and eye/face wash equipment, the advice of a qualified first aid representative or medical advisor should be sought to establish the most suitable location and procedures for first aid and decontamination.
Installation should be in accordance with local legislation and industry standards such as EN15154 and/or ANSI Z358.1-2014 recommendations. Visit www.hughes-safety.com/standards for more information.
Location & Accessibility
•
•
•
•
•
Emergency safety showers and eye/face wash equipment must be installed within 20 metres, or 10 seconds reach of, and on the same level as, a potential hazard. Where strong acids or caustics are used, equipment must be immediately adjacent to the hazard and outside of any spray paths.
Equipment must be in a prominent position, free from any obstructions and clearly visible.
Adequate drainage should be available in the area around and underneath the safety shower or eye/face wash. Consideration should be given to the placement of equipment in the vicinity of the safety shower that are sensitive to water or diluted chemicals, notably electrical items.
For equipment located indoors, wastewater must be contained for subsequent safe disposal or there must be adequate drainage. Procedures must be in place for cleaning residue water after safety shower use.
Loose objects or gravel should not obstruct the operation of the shower where walk-on foot panels or foot treadles are fitted.
Visibility
•
•
An ISO 3864.1 compliant safety sign should be displayed on or near the safety shower or eye wash. The sign should be well positioned so it is visible to all within the hazardous area.
The area must always be well lit with the operating mechanism remaining clearly visible.
Installation and Commissioning
Assembly and mounting
The safety shower may be supplied partially assembled to reduce transport costs (unless specified otherwise at point of ordering).
Equipment must be mounted to a suitable level surface using bolts of a length and type to suit the base material. Please refer to the general arrangement drawings for position of fixing bolt holes.
Once mounted, the stability should be tested to ensure it is safe and poses no danger to the user.
Please note that space should be made available above the shower to enable removal of the tank lid for maintenance purposes.
Installation of safety showers
Once assembled, the shower rose or nozzle, and eye wash diffusers should be removed during initial flushing.
All pipework should be flushed prior to connection to clear the line of all installation debris.
The shower should be activated to ensure proper operation.
Care must be taken not to over-tighten the shower rose, nozzle or eye wash diffusers when replacing after flushing.
The commissioning procedure for the syphon dump valve optional fitting (if purchased) can be found at www.hughes-safety.com using the search function.
CAUTION: For units with electrical heating, it is essential that a water supply is established, and the equipment is checked before connection to an electrical supply.

Installation of eye and eye/face washes
Prior to initial operation it is advisable to remove the “Y” strainer filter basket, where fitted, along with the diffusers to ensure they are free of any debris. Once refitted, test to verify proper operation. (see fig. 1 and fig. 2)
Once the Y strainer head is removed, using a 22mm box spanner or socket, the gauze filter can also be removed and cleaned. (see fig. 1)
If necessary, the flow rate of the eye/facewash diffusers be adjusted via the three-pronged regulator or using the grub screws on each side of the tee-piece in the centre of the eye/facewash bowl. A 4mm allen key will be required for this adjustment. (See fig. 3)

Fig. 1
Water supply and supply pipe materials
Emergency safety showers and eye/face wash equipment must be fed from a potable water supply – drinking water or water of a similar quality.
Minimum Supply Pressure: 0.5 Bar (7 PSI) Maximum Supply Pressure: 7 Bar (101 PSI)
Where a high unregulated pressure is experienced, this must be monitored to ensure it does not exceed the recommended maximum. If the water pressure exceeds the recommendations, please contact Hughes Safety Showers for advice.
The water supply pipe must be of a material compatible with the safety shower and/or eye/face wash equipment to avoid corrosion.
The supply pipe should have at least the same diameter as the inlet pipe on the equipment.
If required, the supply pipe should be fitted with a non-return check valve.
Minimum flow rates must be in accordance with International and European standards, namely EN15154 or ANSI Z358.1-2014.
Water inlet size: Please refer to your general arrangement drawing for details.
Good practice: Fit isolation valves to the supply pipes in an accessible position for use during maintenance. These valves should have locking mechanisms to prevent unauthorised shutoff and be labelled accordingly with fixed permanent tags.
Electrical supply
Where an emergency safety shower, eye or eye/face wash unit requires an electrical supply, either for heating, cooling, alarms or lighting, then the supply should conform to the requirements as detailed in the job specific electrical drawings.
Electrical equipment fitted to these units should be supplied through a safety protection device (MCB, RCD, RCCB for example) to provide additional protection against electric shock while also ensuring satisfactory protective bonding arrangements are in place. Please consult a qualified electrician when installing & commissioning electrical equipment.
CAUTION: Safety showers with non-certified electrical equipment cannot be used in hazardous areas, as per IEC- 60079-10 and API RP 505.
To comply with ATEX Directive 2014/34/EU please note: “The enclosure is non-conducting and may generate an ignition- capable level of electrostatic charges under certain extreme conditions. The user should ensure that the equipment is not installed in a location where it may be subjected to external conditions (such as high-pressure steam) which might cause a build-up of electrostatic charges on non-conducting surfaces. Additionally, cleaning of the equipment should be done only with a damp cloth.”

Servicing and cleaning (continued)
Safety showers:
• Remove the shower head/nozzle periodically to clean, disinfect and ensure any build-up of debris or bacteria is
removed.
• Remove the shower rose and replace after flushing.
Tank Showers (we strongly recommend organising a service via Hughes): Tank showers should be internally disinfected to combat legionella and other bacteria growth.
•
•
•
The water supply is isolated, the shower rose and filter is removed and placed in a container of 50 PPM dissolved Free Chlorine for 1 hour. The lid is removed and the tank is cleaned then refilled with clean water. Chlorine release agent is added to the water to gain 50 PPM of Free Chlorine for 1 hour. The eye bath is operated to hold chlorinated water in the feed line. After being left for one hour, the system is emptied and flushed with clean water before being refilled. The rose and filter are replaced.
Eye and eye/face washes:
•
The fine mesh strainers should be cleaned regularly, particularly in the first 6 months of service as there may be contamination of the water from dirt, jointing compounds, etc. which may have remained in the pipework following installation, despite the recommended flushing procedure.
• Nozzles should be cleaned regularly; the frequency will depend on the ambient conditions of the installation. • Diffusers can be unscrewed for cleaning. •
To clean the ‘Y’ strainer filter basket remove the strainer housing using a 22mm socket. The filter basket can be found inside the housing and can easily be removed for cleaning. To ensure hygienic operation, the diffusers and filter baskets should be replaced if they become excessively dirty or damaged. After any cleaning or maintenance work has been carried out on the equipment it is imperative that the eye and eye/face washes are given a full operational test and any flow regulator or volume control screws are re-adjusted to ensure optimum performance. It is recommended that eye wash diffusers are replaced every six months.
•
Electrical equipment:
•
Thorough visual inspections should be carried out to check for external damage to the electrical units, their cables or the junction boxes. Should any part be found to be damaged, this must be reported and repaired or replaced as soon as possible. A further test should be carried out to establish that it functions as intended. Any additional electrical tests should be carried out at the discretion of a qualified electrician.
Out of Service Procedure
In the event of an emergency safety shower, eye bath or eye/face wash unit being temporarily out of service, a standard procedure should be followed.
Place a sign on the unit indicating it is ‘Out of Service’.
• • Notify the relevant manager/supervisor of the area that the unit is out of service • •
Prohibit or suspend any work where there is a significant hazard requiring use of the unit If work cannot be prohibited or suspended, a portable unit must be provided to supply the initial wash only, after which it will be necessary to move the person to a plumbed emergency safety shower, eyebath or eye/face wash unit to complete the procedure.
Note: Portable units are not acceptable as a long-term substitute for permanent locations.
