ISEA Z In addition to addressing design and engineering issues, specifiers must be aware of regulatory requirements and compliance standards. ANSI Z In order to provide additional guidance to employers, the American National Standards Institute ANSI has established a standard covering emergency eyewash and shower equipment. In this Checklist, we have summarized and graphically presented the provisions of the standard.
This Checklist can serve as a starting point for designing emergency eyewash and shower systems. The standard is part of the building code in locations which have adopted the International Plumbing Code. It was revised in , , , , and again in This Compliance Checklist summarizes and graphically presents the provisions of the version of the standard.
OSHA has adopted several regulations that refer to the use of emergency eyewash and shower equipment. The primary regulation is contained in 29 CFR In addition to these provisions, there are some general provisions that apply to all emergency equipment. In addition to these general provisions of the standard, there are also considerations that are not addressed by the standard.
We believe that these considerations should also be addressed when considering emergency equipment. These include the following: 1. As such, they are a form of first 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. The equipment must be installed on the same level as the hazard i.
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. For example, 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. However, where it is possible that a chemical reaction might be accelerated by warm water, a medical professional should be consulted to determine what the optimum water temperature would be.
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 blending valve to mix the water to the desired temperature. STG offers a variety of mixing www. Please contact our office for further information. It may be advisable to install a shut off valve on the water line, upstream of the unit, to facilitate maintenance of the equipment.
If a shut off valve is installed, provision must be made to prevent unauthorized closure of the shut off valve. Sections 4. Only maintenance personnel should be authorized to place a handle on or unlock the valve. 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 specifically requires that valves be resistant to corrosion.
Materials that are considered acceptable for this purpose include galvanized steel and many types of plastic 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:? Such areas may include any type of outdoor area bulk material handling facility, tank farm, etc. In these cases, the emergency equipment must be protected against freezing. There are a number of different types of freeze-resistant equipment, including:?
Units that have a temperature actuated bleed valve that permits water to flow 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 remoteactivated.
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. 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. After an emergency eyewash or shower has been used, the waste water may contain hazardous materials that cannot or should not be introduced into a sanitary sewer.
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. We offer a variety of alarm systems which may be installed in conjunction with our emergency equipment. They serve to alert personnel and summon assistance if an eyewash or shower is activated. STG offers detailed installation, operation and maintenance guides for its equipment.
These guides are available on the STG website Note: This ANSI Compliance Checklist is intended to assist design personnel, facility owners and others in selecting, specifying, installing and maintaining emergency equipment. We have tried to assure that it is comprehensive and accurate. STG Equipment cannot be responsible for any errors or omissions from this Checklist, and cannot assure that any particular product will perform satisfactorily in any particular application.
Please refer to the standard for a complete listing of these provisions. Section 4. Area around the shower shall be well-lit. Please refer to the standard for a complete listing of these provisions Controlled, low velocity flow completely rinses eyes and face and is not injurious to user.
Section 6. Water flow is sufficiently high to allow user to hold eyes open while operating. Covers shall be removed by water flow. Water flow covers area indicated on STG test gauge. Section 5. Where strong acids or caustics are being handled, the eyewash shall be located immediately adjacent to the hazard. Area around eyewash shall be well-lit. These dual purpose units can be used to combine an eyewash and a drench hose into a single versatile, economic unit.
To use the unit as a fixed eyewash, simply leave the unit in the holder. The dual spray heads will deliver water to both eyes simultaneously. To function as a drench hose, remove the unit from the holder and rinse any part of the eyes, face or body. These units are particularly useful in areas such as laboratories where workers are handling relatively small quantities of injurious materials.
Controlled, low velocity flow rinses both eyes and is not injurious to user. Sections 5. Area around unit shall be well-lit. In other words, drench hoses are intended solely as supplemental units providing additional protection to personnel. Drench hoses are useful in cases where the user is in a prone position or where it is necessary to reach areas of the face and body inaccessible to the fixed stream of a shower or eyewash unit.
They are also advantageous in areas such as laboratories where they can be installed close to where accidents might occur. Controlled, low velocity flow is not injurious to user. Section 8. Area around drench hose shall be well-lit. Connect unit to water supply capable of delivering required flow when all components are operated simultaneously.
Section 7. Area around safety station shall be well-lit.
