FOREWORD
Businesses use products with hazardous properties (hazardous substances) on a daily basis. Goods that are ammable, corrosive,
explosive, toxic, oxidising or ecotoxic are useful because of their hazardous properties i.e. petrol that didn’t ignite wouldn’t be a
very useful fuel for vehicles.
However, because of their properties, hazardous substances can cause serious harm to people and the environment and
additional care must be taken when storing, handling and disposing of these substances.
Dalton International is dedicated to preventing harm from hazardous substances to people and the environment. We do this every
day by working towards our Vision of being New Zealand’s leading provider of safety solutions for businesses working with
hazardous substances.

INTRODUCTION
INTRODUCTION
The selection of emergency eyewash and shower equipment is often a complicated process. In addition to addressing design and
engineering issues, speciers must be aware of regulatory requirements and compliance standards. In Australia and New Zealand
the relevant standard is AS4775:2007 “Emergency Eyewash and Shower Equipment” which sets out requirements for the proper
selection, installation, operation and maintenance of emergency equipment. AS4775:2007 is based on the American standard
ANSI/ISEA Z358.1 and is essentially replicated with change to the units of measure and some other minor changes. E.g. the shower
minimum owrate requirement of 20 GPM (Gallons per minute) in the ANSI standard is changed to 75.7 LPM in the AS/NZS
standard.
To assist speciers and end users in understanding the provisions of the AS4775:2007 standard, Dalton International Ltd has
prepared this Compliance Checklist. In this Checklist, we have summarised and graphically presented the provisions of the standard.
This Checklist can serve as a starting point for designing and planning emergency eyewash and shower systems and also highlights
the maintenance requirements to ensure your chosen equipment continues to function properly.
LEGAL REQUIREMENTS
The Health and Safety at Work Act 2015 (HSWA) is New Zealand’s workplace health and safety law. It introduced new responsibilities
for managing the work-related risks that could cause serious injury, illness or even death.
In workplaces where there is a risk of chemical spills, splashes or accidents the PCBU (Person In Charge of Business or Undertaking)
is required to take all practicable steps to ensure that risks are identied, and either eliminated, isolated or as a last resort mitigated.
Providing emergency showers and eyewashes that comply with AS4775:2007 is part of the solution to mitigate the risk of chemical
splashes.
AS4775:2007 & ANSI Z358.1
AS4775:2007 is based on the American standard ANSI Z358.1 but is not identical. Some minor changes have been made to address
the specic needs of Australian applications, and integrate with other Australian Standards. The main dierences are as follows:
Inclusion of guidance on dimensional constraints for disabled access.
Inclusion of guidance on local materials for plumbing components.
Inclusion of guidance on good design and manufacture.
AS4775:2007 covers the following types of equipment:
Emergency shower equipment.
Eyewash equipment.
Eye/face wash equipment.
Combination shower and eyewash or eye/face wash equipment.
Facilities for disabled persons.
Supplemental equipment including drench hoses and self-contained equipment
The objective of this Standard is to provide uniform minimum requirements for equipment performance, installation, use,
maintenance and training of users, along with relevant test procedures.
This Compliance Checklist summarises the key parts of the standards. It is not intended as a replacement for reading the standards
and we strongly recommend that a copy of the standard be purchased and understood before purchasing any emergency shower
or eyewash equipment.

GENERAL CONSIDERATIONS
01
FIRST AID DEVICES
Emergency eyewash and shower units are designed to deliver water to rinse contaminants from a user’s
eyes, face or body. As such, they are a form of rst aid equipment to be used in the event of an accident.
However, they are not a substitute for primary protective devices (including eye and face protection and
protective clothing) or for safe procedures for handling hazardous materials.
02
LOCATION OF EMERGENCY EQUIPMENT
In general, the standard provides that emergency equipment be installed within 10 seconds walking time
from the location of a hazard (approximately 16m). The equipment must be installed on the same level as the
hazard (i.e. accessing the equipment should not require going up or down stairs or ramps). The path of travel
from the hazard to the equipment should be free of obstructions and as straight as possible.
However, there are certain circumstances where these guidelines may not be adequate. Where workers are
handling particularly strong acids, caustics or other materials where the consequences of a spill would be
very serious, emergency equipment should be installed immediately adjacent to the hazard.
Laboratory environments may also require special consideration. It has been common in many laboratory
buildings to install emergency equipment in a corridor or hallway outside of the lab room. Since a door is
considered an obstruction, this violates the provisions of the standard. For laboratory environments, we
recommend installing (i) recessed laboratory eyewash/shower cabinets inside the lab room and (ii) dual
purpose eyewash/drench hose units at lab sinks. The recessed cabinet units are a space saving design
that satisfy the standard’s requirements for both a shower and an eye/face wash, and are wheelchair
accessible, while the eyewash/drench hoses provide immediate protection for the eyes, face or body when
a spill involves a relatively small amount of hazardous material.

GENERAL CONSIDERATIONS
05
CORROSION RESISTANCE
Once connected to a water supply line, water will enter the emergency equipment and stand in the unit
up to the valve(s). When activated, water will ow through the entire unit. Therefore, the unit must be
constructed of materials that will not corrode when exposed to water for extended periods of time. In addition
to this general provision, the standard specically requires that valves be resistant to corrosion. Emergency
equipment should therefore be constructed of materials that will resist rusting and corrosion. Materials that
are considered acceptable for this purpose include brass, galvanized steel and many types of plastics (ABS,
nylon, etc.). However, these materials may not provide durable service when exposed to harsh industrial
conditions, may deteriorate in direct sunlight or be subject to other limitations.
Therefore, for maximum durability, the following materials should also be considered:
Epoxy coated galvanized steel
Epoxy coated brass
Stainless steel
PVC
06
FREEZING
There are many applications where emergency equipment must be installed in areas that are subject to
freezing conditions. Such areas may include any type of outdoor area (bulk material handling facility, tank
farm, etc.), as well as some interior areas (loading docks, low temperature facilities, etc.). In these cases, the
emergency equipment must be protected against freezing.
Equipment that is designed and manufactured to be freeze-resistant should be installed. There are a
number of dierent types of freeze-resistant equipment, including:
Units that have a temperature actuated bleed valve that permits water to ow through the unit when
the temperature drops below freezing. These units are generally used only where the possibility of
freezing is very infrequent.
Units on which the valve is mounted behind a wall or buried below the frost line and is
remote-activated.
Combination units that are electrically heated (heat-traced) and insulated.
Units that have a heated enclosure to fully contain and protect both the equipment and the user.
03
WATER TEMPERATURE
The standard states that the water temperature delivered by emergency equipment should be ‘tepid.’
Tepid is dened to be between 16°C and 38°C. However, in circumstances where a chemical reaction is
accelerated by ushing uid temperature, a facilities safety/health advisor should be consulted to determine
the optimum water temperature for each application.
The delivery of tepid water to emergency equipment may raise complicated engineering issues. At a
minimum, it generally involves providing both hot and cold water to the unit, and then installing a mixing
valve to blend the water to the desired temperature. Guardian oers a variety of mixing valves and turnkey,
recirculating tempering systems to provide tempered water. Please contact Dalton International’s oce for
further information.
04
SHUT OFF VALVES
Plumbed emergency equipment must be connected to a potable water supply line. It may be advisable to
install a shut o valve on the water line, upstream of the unit, to facilitate maintenance of the equipment. If a
shut o valve is installed, provision must be made to prevent unauthorized closure of the shut o valve. Such
provision can include removing the handle of the shut o valve or locking the valve in the open position. Only
maintenance personnel should be authorised to place a handle on or unlock the valve.

GENERAL CONSIDERATIONS
07
DISPOSAL OF WATER
The standard does not include any specic provisions regarding the disposal of waste water. However,
designers must give consideration to where waste water will go. In particular, care must be taken that waste
water not create a hazard (i.e. by creating a pool in which someone might slip) or freeze.
Generally, Guardian eyewash, eye/face wash and safety station units are designed with waste connections
for connection to drain piping. WE RECOMMEND THAT EMERGENCY EYEWASH AND SHOWER UNITS
BE CONNECTED TO DRAIN PIPING. FOR EMERGENCY SHOWERS AND FOR OTHER UNITS WITHOUT
WASTE CONNECTIONS, FLOOR DRAINS SHOULD BE PROVIDED.
After an emergency eyewash or shower unit has been used, the waste water may contain hazardous
materials that cannot or should not be introduced into a sanitary sewer. It may be necessary to connect the
drain piping from the emergency equipment or oor drain to the building’s acid waste disposal system or to
a neutralising tank.
08
EMERGENCY RESPONSE
Simply installing emergency equipment is not sucient to assure worker safety. Employees must be trained
in the location of emergency equipment and in its proper use. Emergency equipment must be regularly
maintained (including weekly activation of the equipment) to assure that it is in working order and inspected
at least annually for compliance with the standard. Most importantly, employers should develop a response
plan to be used in the event that an accident does occur. The focus of the response plan should be to provide
assistance to the injured worker as quickly as possible.
Guardian oers a variety of alarm systems that may be installed in conjunction with our emergency
equipment. They serve to alert personnel and summon assistance if an eyewash or shower is activated.
WE RECOMMEND INSTALLING AN ALARM UNIT WITH ANY EMERGENCY EYEWASH OR SHOWER UNIT.
09
O&M INFORMATION
Under the standard, the manufacturer of the emergency equipment must provide detailed instructions on
the proper operation, inspection and maintenance of the emergency equipment. This information should
be accessible to maintenance personnel. Guardian oers detailed installation, operation and maintenance
guides for its equipment. These guides are available on the Dalton International’s website (dilnz.co.nz) and
from our sales representatives.

GUARDIAN TECHNOLOGY
GUARDIAN EMERGENCY EYEWASH AND SHOWER TECHNOLOGY:
ENGINEERED FOR TODAY’S INDUSTRIAL ENVIRONMENTS.
Safe workplaces demand advanced emergency eyewash and shower equipment. Guardian is proud to oer the most complete
selection of emergency equipment designed for today’s industrial applications. Characterised by enhanced performance and
superior durability, all Guardian products feature the latest innovations in spray head technology. The unique GS-Plus™ and
FS-Plus™ spray heads deliver water in a soft, wide spray rather than a solid, narrow stream. The user receives more water over a
wider area than with any other type of outlet head. In an emergency, contaminants are ushed away quickly, gently, and completely.
These heads incorporate a variety of unique and important features:
CONSISTENT, BALANCED FLOW
An engineered ow control located inside each spray head is
calibrated to deliver 6.9 (GS-Plus™) or 12.1 (FS-Plus™) litres per
minute, at pressures from 20 to 100 PSI. The ow is consistent,
and evenly balanced between the spray heads
regardless of line pressure.
“FLIP TOP” DUST COVER
Each spray head is protected against dust and dirt by a “ip
top” cover which nests into the top of the outlet head when
equipment is not in use. Upon unit activation, water ow
swings the cover o the head. The cover is permanently
attached to the spray head by a stainless steel pin to pre-
vent removal or loss. Optional stainless steel covers are also
available.
FILTERED WATER
Each spray head contains an internal lter to
remove particles and debris from the water ow. During
ushing, the user’s eyes and face are protected against
any potential foreign matter which may exist in the water
or plumbing lines.
DURABILITY
The spray head bodies are molded from
tough, impact-resistant and corrosion
resistant polypropylene, while the “ip top”
dust covers are molded nylon. Both the
GS-Plus™ and FS-Plus™ spray heads stand up
to the harshest laboratory environments.
EASY MAINTENANCE
Water often contains dissolved minerals and
foreign matter which, over time can build up
and clog any spray head. The GS-Plus™ and
FS-Plus™ spray heads are designed such
that all working components are contained
within the head itself, making cleaning and
maintenance easy. Guardian’s emergency
equipment should never need disassembly in
the event of a clogged spray head.

CORROSIVE RESISTANCE GUIDE
Standard emergency eye wash and shower equipment is constructed from a variety of materials, including stainless steel (shower
pull rods and actuating arms), chrome plated brass (valves and eye wash components) and galvanized steel (pipe and ttings). In
addition, standard units may include plastic components (shower heads, eye wash bowls, spray heads, etc.) that are molded from
ABS, polypropylene and/or nylon.
When installed in industrial environments, emergency eye wash and shower equipment is exposed to all of the conditions present
in the environment, including temperature, humidity, sunlight and chemicals that may be present. In particular, the equipment
can be exposed to acids, caustics and other chemicals that will cause the materials in the equipment to corrode. Such corrosion
is a serious matter, since it can cause the equipment to deteriorate to the point of becoming nonfunctional. In an emergency,
the equipment may not be available to an injured person. While Guardian carefully selects the materials used in its products, the
possibility of corrosion cannot be eliminated.
Guardian oers several alternatives for improving the corrosion resistance of emergency equipment:
Powder Coated Finish. All of our units can be furnished with a powder coated nish applied over the galvanized steel and brass
components. The surfaces to be coated are cleaned and etched with phosphoric acid solution. Epoxy/polyester hybrid pow-
der is electrostatically applied to the metal surfaces and then baked to cure. The result is a smooth, hard surface that provides
excellent resistance to corrosion. Guardian powder coating is available in a variety of colors, including high visibility orange,
green, yellow and red. These colors provide the equipment with increased visibility in the industrial environment.
Polyvinyl Chloride (PVC) Construction. Guardian oers a wide array of units that are constructed of PVC and PVC-coated ma-
terials. All pipe and ttings are PVC. Valves, actuators and other components are brass with a PVC coating. These units can
provide better durability than standard emergency equipment in certain environments.
Stainless Steel. Guardian also oers a wide selection of units that are constructed entirely of stainless steel. These units are
highly resistant to corrosion, and are ideal for use in areas such as laboratories and clean rooms.
In order to assist in selecting the equipment that is best suited for a particular application, Guardian has compiled a “Corrosion
Resistance Guide”. This corrosion information is oered as a guideline only, to assist in selecting the equipment that will be best
suited for the user’s application.
Due to the innite number of combinations of chemicals found in any environment, as well as the eects of chemical
concentration, temperature, humidity, etc., Guardian cannot predict and cannot be held responsible for the eects of any
particular environment on any specic installation of emergency eye wash and shower equipment.

CORROSIVE RESISTANCE GUIDE
Notes:
The above table presents the relative corrosion resistant abilities of certain materials in the specic corrosive environments
described. This information should be considered as a general guide only. The table does not provide information on possible
combinations of concentrations of corrosive media or temperature levels that may be found in the eld. Even small changes
in the concentration of the corrosive media or in the temperature at which interaction takes place may generate dierent
results from those described above. Results dierent from those shown above may also result from impurities in the metals
or plastics, the actual condition of the environment in which the materials are used, or other factors.
NO GUARANTEE OF THE PERFORMANCE OF ANY METAL OR PLASTIC DESCRIBED IN THE TABLE IS EXPRESSED OR SHOULD BE IN-
FERRED. GUARDIAN RECOMMENDS THAT MATERIAL SAMPLES BE SUBJECTED TO ACTUAL OPERATING CONDITIONS BEFORE FINAL
SPECIFICATION.
The corrosion resistance data for powder coating is based upon laboratory testing consisting of subjecting coated samples
to drops of the listed chemicals for ten minutes. Dierent results may be obtained when coated materials are subjected to
chemicals for longer periods of time.
