Eye/face wash unit location:
Install eye/face wash unit within 10 seconds (approximately 55 feet) of hazard, on the same level as hazard and with unobstructed travel path. Where strong acids or caustics are being handled, the eye/face wash shall be located immediately adjacent to the hazard. (Section 6.4.2; B5)
identification:
Identify eye/face wash with highly visible sign. Area around eye/face wash shall be well lighted. (Section 6.4.3)
water temperature:
Water delivered by eye/face wash shall be tepid (60-100ºF). (Section 6.4.6)
training:
Instruct all employees in the location and proper use of eye/face washes. (Section 6.5.4)
maintenance/inspection:
Activate eye/face wash at least weekly. (Section 6.5.2) Inspect annually for compliance with standard. (Section 6.5.5)
The selection of emergency eyewash and shower equipment is often a complicated process. In addition to addressing design and engineering issues, specifiers must be aware of regulatory requirements and compliance
standards. A common reference point when specifying emergency equipment is ANSI/ISEA Z358.1, “Emergency Eyewash and Shower Equipment.” This standard is a widely accepted guideline for the proper selection, installation and maintenance of emergency equipment.To assist specifiers in understanding the provisions of this standard, Guardian Equipment has prepared this ANSI Compliance Checklist. 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.
legal requirements:
The Occupational Safety and Health Act of 1970 was enacted to assure that workers are provided with “safe and healthful working conditions.” Under this law, the Occupational Safety and Heath Administration (OSHA) was created and authorized to adopt safety standards and regulations to fulfill the mandate of improving worker safety. OSHA has adopted several regulations that refer to the use of emergency eyewash and shower equipment. The primary regulation is contained in 29 CFR 1910.151, which requires that...“...where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be
provided within the work area for immediate emergency use.
general considerations:
ANSI Z358.1- 2009 contains provisions regarding the design, certification, performance, installation, use and maintenance of various types of emergency equipment (showers, eyewashes, drench hoses, etc.). 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. 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 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.
2. LOCATION OF EMERGENCY EQUIPMENT:
In general, the ANSI standard provides that emergency equipment be installed within 10 seconds walking time from the location of a hazard (approximately 55 feet). 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. 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 now considered an obstruction, this no longer satisfies 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 (see page 8). 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 handicapped 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.
3. WATER TEMPERATURE:
The 2009 version of the standard states that the water temperature delivered by emergency equipment should be “tepid” (60- 100ºF). 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. Guardian offers a variety of mixing valves and turn-key, recirculating
tempering systems to temper water. Please contact our office for further information.
4. SHUT OFF VALVES:
Plumbed emergency equipment must be connected to a potable water supply line. 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 4.1.2, 4.5.5, 5.1.6, 5.4.5, 6.1.6, 6.4.5, 8.2.3.3) Such provision can include removing the handle of the shut off valve or locking the valve in the open position. Only maintenance personnel should be authorized to place a handle on or unlock the valve.
5. CORROSION RESISTANCE:
Once connected to a water supply line, water will enter the emergency equipment up to the valve(s). Therefore, the unit must be constructed of materials that will not corrode when exposed to water for extended periods of
time. (Sections 4.1.5, 5.1.5, 6.1.5). In addition to this general provision, the standard specifically requires that valves be resistant to corrosion. (Sections 4.2, 5.2, 6.2, 8.2.2) Emergency equipment should therefore be constructed of
materials that will resist rusting and 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:
• Epoxy coated galvanized steel
• Chrome plated brass
• Stainless steel
• PVC
6. 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. (Sections 4.5.5, 5.4.5, 6.4.5, 7.4.4, 8.2.3.3) Alternatively, equipment
that is designed and manufactured to be freeze-resistant should be installed. 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
7. DISPOSAL OF WATER:
The standard does not include any 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 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 floor drain to the building’s acid waste disposal system or to a neutralizing tank.
8. EMERGENCY RESPONSE:
Simply installing emergency equipment is not a sufficient means of assuring 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. 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. WE RECOMMEND INSTALLING AN ALARM UNIT WITH ANY EMERGENCY EYEWASH OR SHOWER UNIT.
