General Considerations
When planning the installation of emergency safety showers and eye/face wash equipment, the advice of a qualied rst
aid representative or medical advisor should be sought to establish the most suitable location and procedures for rst 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.
• 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 tted.
• 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.
Location & Accessibility
Visibility
Installation and Commissioning
The safety shower may be supplied partially assembled to reduce transport costs (unless specied 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 xing bolt holes.
Once mounted, the stability should be tested to ensure it is safe and poses no danger to the user.
Assembly and mounting
Once assembled, the shower rose or nozzle and eye wash di󰀨users should be removed during initial ushing.
All pipework should be ushed 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 di󰀨users when replacing after ushing.
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.

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: 29 PSI (2 bar G)
Maximum Supply Pressure: 87 PSI (6 bar G)
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 tted with a non-return check valve.
Minimum ow rates must be in accordance with International standards, namely 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 shuto󰀨 and be labelled accordingly with xed permanent tags.
Installation of eye and eye/face washes
Water supply and supply pipe materials
Prior to initial operation it is advisable to remove the “Y” strainer lter basket, where tted, along with the di󰀨users to ensure
they are free of any debris. Once retted, test to verify proper operation. (see gs. 1, 2, 3 and 4)
If tted, the Y strainer head is removed, using a 22mm box spanner or socket, the gauze lter can also be removed and
cleaned. (see g. 1)
If necessary, the ow rate of the eye/facewash di󰀨users 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 g. 5) or via the ow regulator knob on the side of the eyewash. (See g. 3)

Operation
Employees working within hazardous areas must be trained in the use and location of emergency safety showers
or eye/face wash equipment. Instructions for all emergency equipment should be readily available and accessible
to personnel.
Safety shower activation methods (where tted):
• Pull handle
• Push down lever
• Foot treadle
• Walk on foot panel
• Push activated panic bar (emergency tank showers only)
For optimum safety, the valves remain open when activated and must be shut o󰀨 manually.
Eye and eye/face wash activation methods (where tted):
• Lift lid
• Pull lid down
• Push plate
• Push down lever
• Foot treadle
Maintenance
Regular servicing and maintenance of emergency safety shower and eye/face wash equipment is essential to ensure
correct functionality. All services and weekly activations must be recorded to ensure a full history is maintained as per
European and International standard requirements.
Weekly activation
All equipment should be visually inspected and activated at least once a week to ensure it is operating properly, to clear
the line of any sediment build up and check that the water runs clear.
Where tted, the external test handle can be used for ease.
Please visit www.hughes-safety.com/weekly-activation to download the checklist and video detailing what to look out for to
remain compliant.
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 specic electrical drawings.
Electrical equipment tted 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. Installation, commissioning and maintenance of any electrical equipment should be completed
by a qualied electrician in compliance with all national and local codes.
Before working on the units power must be turn o󰀨. A disconnect switch is recommended to safely interrupt power supply to
the unit. Disconnect switches are in the customer scope of supply or available as an option from Hughes.
CAUTION: Safety showers for general purpose electrical areas cannot be used in hazardous areas, as per NFPA 70
and CSA 22.2. When making electrical connections be sure to follow all lockout-tag out safety procedures.
Electrical supply

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 signicant 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.
A selection of our emergency safety showers are available to hire. Ensure your workforce are protected around
the clock, visit www.hughes-safety.com/us/rentals for more information.

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 qualied electrician. In compliance with all national and
local codes.
Servicing and cleaning
Hughes recommend equipment be serviced and cleaned regularly, and at least every 6 months. To purchase spare parts call
us on (1) 866-312-1652 or email [e-mail]
Periodic analysis of the water quality is recommended to ensure there is no build-up of harmful bacteria.
Regular cleaning of the outside of the emergency equipment is recommended. Abrasives or solvents must not be used to
clean the unit as this can damage the surface or a󰀨ect the instruction stickers.
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 ushing.
Eye and eye/face washes:
• The ne mesh strainers should be cleaned regularly, particularly in the rst 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 ushing procedure.
• Nozzles should be cleaned regularly; the frequency will depend on the ambient conditions of the installation.
• Di󰀨users can be unscrewed for cleaning.
• To clean the ‘Y’ strainer lter basket remove the strainer housing using a 22mm socket. The lter basket can be
found inside the housing and can easily be removed for cleaning. To ensure hygienic operation, the di󰀨users and
lter 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 ow regulator or volume control screws are re-adjusted
to ensure optimum performance. It is recommended that eye wash di󰀨users are replaced every six months.
