For over 103 years, Haws has been committed to bringing the highest quality water delivery and emergency equipment products to a wide variety of markets.

General Installation and Maintenance Information

General Rules
Emergency equipment manufactured by Haws Corporation is warranted to function if installed per provided installation and maintenance instructions. The units also must be used for the purpose for which they were intended. This product is intended to supplement first aid treatment.
Due to widely varying conditions, Haws cannot guarantee that the use of this emergency equipment will prevent serious injury or the aggravation of existing or prior injuries.

OSHA
Haws Emergency Equipment enables you to meet the requirements in the OSHA Rules and Regulations covering this type of equipment.

ANSI
Haws Emergency Equipment is manufactured to meet ANSI Z358.1 - 2009 for Emergency Eyewash and Shower Equipment.

WARNING ALARM SYSTEMS
In remote areas, or in hazardous locations where there are very few people, a Haws Model 9001 alarm system should be installed. This alarm activates when the shower or the eyewash unit is used in order to summon help to the injured party.

WARNING
Eyewash and eye-face wash fountains should not be used if it is known that eye contamination is metal or some other rigid solid fragment. In such an event, both of the victim's eyes should be gently immobilized in accordance with the current Red Cross Standard First Aid Manual and medical attention immediately sought.

IDENTIFICATION & SIGNAGE
Units should be installed in close proximity to hazardous areas, clearly identified as eyewash stations or emergency showers or both, free from obstructions and accessible from three directions.

PROPER DRAINAGE
Appropriate drainage should be considered for emergency showers and other equipment to prevent excess accumulation of water on floors.
 
REGULAR TESTING
All emergency showers and eyewashes should be tested weekly. A testing tag is attached to each unit and is used to record the date of the test and the initials of the tester. If there is no floor drain available for proper testing of the shower, a Haws Shower Test Kit, Model 9010, and container should be used.

INSTALLATION & WATER SUPPLY
Showers and eyewashes should be connected to the main potable water supply, and a loose-key lock-shield type stop or shut-off valve is recommended to allow proper maintenance of the unit. Valve must be labeled to prevent unauthorized shut-off.

FREEZE RESISTANCE
When installations are outside and temperatures drop below 32°F, freeze-proof units are recommended. Precautions should also be taken to protect the user under frigid conditions. It shall be the responsibility of each specifying authority to determine the delivered water temperature that will be required in an area, not only to provide the flow of water as required, but also maintain it at a temperature that will be safe for the user. Delivered water temperature should not be at extremes that might be expected to discourage the unit's effective use under emergency conditions. A comfortable range is 15°C - 35°C (60°F - 95°F). In circumstances where chemical reaction is accelerated by water temperature, a medical advisor should be consulted for the optimum temperature for each application.
 
PROTECTION FROM DEBRIS
Wherever possible, a Haws Model 9070 filter should be provided upstream of the eyewash to remove particles from the water and prevent additional eye damage. Model SP-502, 1/2" Y-strainer is also available. Line size Y-strainer installed in supply line to unit should be considered to reduce chance of debris reaching eyewash and/or shower. When protection of a Haws eyewash from dust or airborne contaminates is necessary, Haws offers Model 9101 Dust Cover, which encloses the bowl and is available for selected eyewash models.

SPECIFIC REQUIREMENTS
These units should be located as close to the hazard as possible without physically causing a hazard themselves, such as protruding fittings. Emergency showers and eyewashes shall be accessible locations that require no more than 10 seconds to reach and should be within a travel distance no greater than 15.24 meters (50 feet) from the hazard. However, the maximum time required to reach the shower or eyewash should be determined by the potential effect of the chemical. For example, exposure to a highly corrosive chemical might require showers to be installed within 3 to 6 meters (10 to 20 feet) from the hazard or eyewashes within 3 meters (10 feet) from the hazard. It is recommended that the consulting physician be contacted for advice on the proper distances.

Precautions should also be taken to protect the user under frigid conditions, including provisions for the proper disposal of the water. Installation procedures should be in accordance with proper plumbing practices, with supply piping sized adequately to meet flow requirements.
Supply lines should be properly flushed prior to installation of emergency units.

EYE & EYE/FACE WASHES
To insure adequate operation of the units, all persons should be instructed in the proper use of both the shower and the eyewash. Affected areas should be rinsed at the scene of the accident for at least 15 minutes, and a doctor or industrial nurse should be contacted immediately.

EMERGENCY SHOWERS
Single head emergency showers should be used in all areas where chemicals are being used or where clothing fires could occur. A companion eyewash should be considered. If hazardous area is large and there are many persons in the area, multiple installations are recommended.
Minimum pipe size to shower should be smaller than 1-1/4" IPS. Dynamic water pressure should be no less than 30 PSI or more than 90 PSI. On showers located more than 50 feet from the main water supply, piping should be sized to provide friction losses no greater than 50 feet of 1-1/2" pipe.
A drain should be provided for the shower.
In case of chemical burns, the victim should shower immediately and a doctor or nurse should be notified.

COMBINATION SHOWERS & EYEWASHES
Combination single head emergency shower and eyewash models are available as a complete emergency station. The emergency shower is available for use against chemical burns and clothing fires and, since an emergency shower should not be used as an eyewash, an individually operated eyewash is also available. These units provide both an eyewash and shower with only one water connection.
A drain should be provided for the shower and the eyewash should be connected to the drainage system.
Minimum pipe size to the combination unit should be no smaller than 1-1/4" IPS. Dynamic water pressure should be no less than 30 PSI during operation of both units. On units more than 50 feet from the main water supply, piping should be sized to provide friction losses no greater than 50 feet of 1-1/2" pipe.
 
EMPLOYEE INSTRUCTION
To insure adequate operation of the units, all persons should be instructed in the proper use of both the shower and the eyewash. Affected areas should be rinsed at the scene of the accident for at least 15 minutes, and a doctor or industrial nurse should be contacted immediately.
