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.

Assembly and mounting
1. Squeeze the lever to release the pressure in the unit.
2. Remove the head assembly and clean all parts thoroughly.
3. Ensure the overll tube is in place.
4. Fill the unit with 11 litres (2.9 US Gallons) of potable water.
5. Replace the head assembly and the safety pin.

of a similar quality.

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.
To operate:
• Pull out the pin
• Remove the dust cover
• Squeeze lever
• Wash the contaminated area until the unit is empty
• Seek medical advice

Hughes recommend equipment be serviced and cleaned regularly, and at least every 6 months. To discuss Hughes service
contract options or to purchase spare parts call us on [phone] 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.
Aerated di󰀨user:
• To clean the aerated di󰀨user, unscrew the removable eyebath cup and dust cover to
expose the aerator
• Unscrew the aerator, taking care not to misplace the internal rubber washer and the green
nylon seating washer.
• Remove the aerator from its housing, and along with the eyebath cup, dust cover and
washers, clean thoroughly.
• No sealants are required when retting (M24 Aerator 01 03 075 0061 – see g. 1)
The water contained within the unit should be replaced at monthly intervals, depending upon the
quality of the local potable water supply, and the unit re-charged. If deterioration of the water is
noticeable, shorten the replacement intervals.
If eyesaline solution is used in the unit, contents should be replaced every six months.
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.
Servicing and cleaning
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.
