MSDS Information

Current MSDS must be readily available for review by all employees.  A master copy of all MSDS, along with a floor plan, should be all located in a strategically accessible location in the event of a fire or similar emergency situation.  This information can be released to the appropriate authorities as required.  In addition, copies of the MSDS information should be available to the Health and Safety Officers and your Medical Department, if applicable. 

In the event of an emergency, the MSDS for that particular hazardous substance should be identified and brought with the patient when further medical help is sought.  This information will aid medical personnel in the proper treatment of the injury.

When addressing Eye Wash requirements, there may initially be some confusion as to the correct type of device required for any and all chemicals within your workplace.  Once you have consulted the secondary and primary eye wash definitions, legislations, and the relevant MSDS First Aid Measures Section for each chemical stored, and/or used in your facility, then there will be no question as to the correct emergency equipment that you must implement.

Please do not mistake a secondary eye wash device for a primary eye wash device.

Quick .pdf Guide to Determine Eye Wash Requirements


Definition of Secondary/Personal Eye Wash Device

Secondary/Personal Eye Wash Devices do not meet the standard for primary devices and are, therefore, intended for support use, not as a replacement for self-contained or plumbed units. These devices are located in the immediate vicinity of employees working in a potentially hazardous area and are used to deliver initial first aid while getting the person to a primary unit, or as extended aid when transporting a person from the primary eye wash unit to a medical facility. Secondary/Personal Eye Wash devices provide less than 15 minutes of flushing.

Important:  All eye care solution dispensed from bottles, should be used directly from the manufacturer's original sealed, sterile bottle.  For your protection, these bottles have an expiry date and include a tamper-proof seal to ensure the solution's integrity is intact.  Once the bottle's tamper-proof seal has been broken, or the solution has been partially used, the bottle and remaining solution must be discarded and replaced with a new sealed bottle. 

Do not transfer solutions into other so-called eye wash dispensing type bottles.  Use directly from the original manufacturer's bottle.

Definition of Primary Eye Wash Device

A Primary Eye Wash Device may be a self-contained, portable or plumbed unit that:

  1. flushes both eyes simultaneously,
  2. delivers not less than 0.4 GPM (1.5 LPM) for a minium of 15 minutes,
  3. activates within 1 second or less,
  4. provides hands free operation,
  5. deliveres flushing fluid at a temperature that is tepid (moderately warm, lukewarm),
  6. has a controlled low velocity flow that is not injurious to the user.

Note:  Eye wash devices attached to faucets, known as faucet mounted eye wash devices, do not comply with ANSI regulations as a primary eye wash device.  They are classified as secondary units and are intended to support, NOT REPLACE the required Primary ANSI approved Emergency 15 minute eyewash devices.

ANSI Z358.1-2004 requires primary eye wash units to deliver adequate/copious amounts of water (minimum of 15 minutes) for rinsing, however, the water flow has to be softened so the force does not drive the contaminants into the optic system. This is one of many reasons why the garden hose idea is not acceptable.

Emergency Eye Wash Regulation

The Occupational Health and Safety Act, passed in 1970, made it mandatory that Emergency Eye Wash and Deluge Shower Equipment be located wherever there is a potential danger from exposure to hazardous materials. The Act states in Section 128 "Where a worker is exposed to a potential hazard of injury to the eye due to contact with a biological or chemical substance, an eye wash fountain shall be provided."

The American National Standard for Emergency Eye Wash and Deluge Shower Equipment ANSI Z358.1-2004 states the following:

E5.5.2 Medical and industrial experiences have shown that the initial first aid treatment for chemical splash should be to wash the eyes for the minimum 15 minutes prior to medical treatment. It is important to hold the eyelids open and roll the eyeballs so the flushing solution used will flow on all surfaces and in the folds surrounding the eyeballs.

The First 10 Seconds Are Critical - Toxic substances, when coming in contact with the eye, immediately begin to damage sensitive eye tissues. The longer they remain in contact, the greater the damage to the eye. Besides tissue damage, acids and alkali can change the pH in the eye itself. When the pH of the eye begins to get out of the narrow tolerable range, severe eye damage, including blindness, may result. Therefore, it is imperative to begin flushing as quickly as possible after the eye comes in contact with a harmful substance . . . the first 10 seconds are critical.

Other Considerations when selecting Emergency Plumbed Equipment

Some of the important elements to consider before selecting and installing emergency equipment:

Location:  Emergency equipment should be free from obstructions and accessible from three sides.

Identification:  All emergency equipment should be identified with highly visible signs.

Water Temperature: 15C to 35C (60F to 95F)

The awareness of the need for warm water Emergency Plumbed Devices has dramatically increased.  The idea has gone from being overlooked and rarely considered to its current status as a major concern within the industry.  Tempered water can be defined as water that has been stabilized; specifically, water that has been warmed or cooled to a desired temperature.  ANSI notes that "delivered water temperature should not be at extremes that might discourage use under emergency conditions.  A comfortable temperature range is between 15C - 35C (60F - 95F).  Water of 27C (80F) is considered optimum for chemical splashes.  While it may be thought of as cool, it can be quite comfortable for any burn related splashes.  Tempered water within the 15C - 35C (60F - 95F) range is desired not only to help cool burns and to help prevent chemical absorption, but it is also desired because it helps prevent hypothermia, encourages the full 15 minute drench time and helps to encourage the removal of contaminated clothing.  This system can be added to your existing plumbed in emergency eye wash, drench shower or combination shower units.

Unlike other mixing valves, the Thermostatic Mixing Valves Talott distributes are designed specifically for Emergency Plumbed Devices.  These units precisely blend hot and cold water to deliver warm (tepid) water as required by ANSI Z358.1-2004.

Water Supply:  A large and continuous supply of potable water with at least 30 PSI flow pressure.  Piping should be at least as large as the inlet size of the unit to be installed.

Freeze Protection: Mechanical or electrical.

Corrosion Protection: Emergency Plumbed Devices are often installed in areas where it is exposed to corrosive materials. In these instances, it is advisable to use equipment which is corrosion resistant. Guardian offers a protective epoxy coating as an optional feature on all its units. Guardian also offers units which are constructed entirely of stainless steel or PVC. Selection of the appropriate corrosion-resistant unit depends upon the materials to which the equipment may be exposed.

Drainage: Since Emergency Plumbed Devices deliver a very high volume of water, we highly recommend that drains be provided, due to the significant water damage that can be caused.  Secondly, the absence of drainage may be a deterrent to routine testing of the Emergency Plumbed Devices, if this is the case, use the Shower Tester Kit.

Alarm Systems: Visual and audible alarm systems might be advisable for Emergency Plumbed Devices, particularly in remote locations or ones where only one employee might be working. This will insure that assistance can be rendered in an emergency situation as quickly as possible.

Accessibility: Guardian responds with an array of "Barrier-Free" products which will assist in complying with government regulations (28 CFR Part 36) and compliance of ANSI Z358.1-2004 Standards for handicapped accessibility.  The Americans with Disabilities Act (ADA) mandates that workplaces be accessible to, and usable by, physically handicapped persons.


Inspection & Maintenance

Remove all impediments that restrict immediate access to Emergency Plumbed Equipment.  ANSI Z358.1-2004 Standards state that each Emergency Plumbed Device should be activated at least weekly to test the equipment and flush plumbed lines of any bacterial or sediment build-up.  In extremely busy environments, or very corrosive atmospheres, the unit should be tested once each shift.  It is important to implement a Safety Test Program and indicate on Talott's Inspection Record Tag (082IMT) that the routine inspection has been performed.

Why Choose Guardian Equipment?


Guardian Equipment has been a leader in the emergency eye wash and shower industry for over 25 years.  Their products are designed for use in demanding applications where reliable performance is of paramount importance.  They design systems for every application and environment, including a host of ADA-compliant (Americans with Disabilities Act) "Barrier-Free" devices.  Guardian also offers a variety of options to aid in the customization of their equipment to your specific needs.  Guardian products are guaranteed for two years, the longest in the industry.

All Guardian products are made in the USA in their own dedicated modern, state-of-the-art facilities.  Assembly by trained technicians takes place on their own premises, and no product is shipped before it has been thoroughly inspected and water tested.  These extra steps taken up front help ensure trouble-free installation and years of dependable performance on your site.  Guardian products are third-party certified to comply with ANSI Z358.1-2004 Emergency Eye Wash and Deluge Shower Equipment.  The certifying agency, ETL Testing Laboratories, Inc., is accredited by OSHA as a Nationally Recognized Testing Laboratory (NRTL).  The ETL mark is accepted world-wide as denoting compliance with recognized standards such as ANSI, IEC, CSA and UL.

Guardian's GS-Plus (1" diameter spray coverage) and FS-Plus (2" diameter spray coverage) outlet heads deliver water in a soft, wide spray rather than a solid, narrow stream.  With this design, the user receives more water over a wider range of coverage in a more gentle flow than with any other type of outlet head.  In an emergency, contaminants are rinsed away quickly, gently and completely.  The GS-Plus spray head is now standard on all Guardian eye wash and the FS-Plus spray head is now standard on all Guardian eye/face wash units.

The GS-Plus and FS-Plus heads represent a truly great innovation in eye wash technology.  Engineered for superior performance, the head incorporates a variety of unique and important features:

  • "Flip Top" Dust Cover - Each outlet head is protected against dust and dirt by a "flip top" cover.  Water flow swings the cover off the head.  The cover is permanently attached to the spray head by a stainless steel pin; the cover cannot be removed or lost.  The cover nests into the top of the outlet head, assuring that the cover always stays on the head when the unit is not in use.
  • Consistent Balanced Flow - An improved flow control located inside the spray head is calibrated to deliver 1.8 GPM  at pressures from 20 to 100 PSI.  The flow is consistent, regardless of line pressure.  Since each head contains an individual flow control, the flow is evenly balanced between the heads.
  • Filtered Water - Each spray head contains an internal filter to remove particles and debris from the water flow.  During rinsing, the user's eyes and face are protected against any foreign matter which may be in the water or the plumbing lines.
  • Durability - The body, spray cover and dust cover are moulded from tough impact- and corrosion-resistant ABS.  They will stand up to even the harshest industrial environments.
  • Ease of Maintenance - Water often contains dissolved minerals and foreign matter which over time can clog up any outlet head.  The Guardian GS-Plus and FS-Plus spray heads are designed so that all working components are contained in the head itself.  All components are readily accessible for cleaning and maintenance.  The unit itself should never need disassembly.
