ANSI standard Z358.1 is detailed in terms of defining what is appropriate for safety showers and eyewash stations.

By Vince McLeod  

As lab managers and employees, we know that many inorganic chemicals (such as the mineral acids and alkalis) are corrosive to the skin and eyes. Likewise we are aware that many organic chemicals (such as acid halides, phenols, and so on) are corrosive and often toxic. Yet we Safety Guys are continually shocked by laissez-faire attitudes toward the use and maintenance of basic safety equipment by lab personnel, and the resultant unnecessary injuries.

One extreme example we constantly recall is the tragic UCLA accident just a few years ago, which resulted in a fatality from chemical burns.1 And we recently noticed a post on the American Industrial Hygiene Association pages for Lab Safety Chemical Exposure Incidents, where improper use of an eyewash resulted in a trip to the emergency room.2

The worker was using a fluorescent stain in the cytogenetics lab and felt something splash into his eyes. He was not wearing safety goggles or glasses. (D’oh!) Long story shortened, he flushed his eyes at the nearest eyewash, but they remained irritated and began to swell shut, necessitating a visit to the emergency room. Back at work a few days later, he noticed a coworker using the same eyewash to clean glassware and stainless steel trays, which were left resting in the sink in a cleaning solution. (What?!)

What does OSHA say?

In 29 CFR 1910.151 Medical Services and First Aid, it states 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.”3 OSHA doesn’t provide more specifics regarding what constitutes “suitable” or how “immediate” is defined. So how do we know if we are meeting the intent of the law?

Fortunately, we have the American National Standards Institute (ANSI), and their consensus standard Z358.1, last updated in 2014. This ANSI standard is very detailed in terms of defining what is appropriate for safety showers and eyewash stations. In fact, OSHA uses this reference as a guide when inspecting facilities. So let’s review what is “recommended” for acceptable safety equipment.

Safety shower specs

Begin by checking your facilities for the proper hardware, as recommended by Z358.1. Rest assured that OSHA will, should one or more agents show up for an inspection. For safety showers, the shower head must be capable of flowing 20 gallons per minute (gpm) at 30 psi and producing a 20-inch diameter spray pattern at 60 inches above the surface where the user stands. The center of the sprayhead pattern should be at least 16 inches from any wall, door, or obstruction. It is recommended that the shower head be mounted between 82 and 96 inches off the floor, with the valve no higher than 69 inches.

Eyewash specs

Eyewash stations target just the eyes and therefore have a lower flow requirement. ANSI Z358.1 recommends a flow of 0.4 gpm also at 30 psi. The nozzles should be at least six inches from any obstruction and mounted between 33 and 45 inches above the floor. An eyewash gauge should be used to verify and test the flow pattern.

Requirements for both

Both safety showers and eyewash stations must be able to provide the recommended flow for at least 15 minutes. This usually translates into having the equipment plumbed in with hard connections to the water supply. For example, a quick calculation for the safety shower at 20 gpm yields 300 gallons needed. Self-contained or personal wash devices are allowed, but they are considered supplemental units that can provide immediate flushing while transiting to the permanent fixture.

If the local climate presents potential for freezing conditions, the equipment must be designed to avoid freezing or protected against that situation. Activation valves must open within one second and remain open until intentionally closed or turned off. It goes without saying that these safety devices should be constructed of corrosion-resistant materials.

The 2014 update to Z358.1 added two important criteria. The first is that the requirement for tepid water is now defined as having a temperature of between 60 and 100 degrees Fahrenheit (15 to 37 degrees Celsius). The second change addresses simultaneous operation for combination units. This means that if you have a drench shower combined with an eyewash station, both devices must provide adequate flows and be fully operable at the same time.

Finally and most importantly, consider the location of equipment. We know you have the 10-second rule etched into your brain, as that is the most critical element when it comes to safety showers and eyewashes. This means that travel to the unit should be under 10 seconds for all hazardous areas that need this equipment. This equals about 55 feet. In addition, the drench shower or eyewash must be on the same level as the hazard and have a clear path for travel. We recommend painting or marking the floor area underneath the shower to help keep it clear. Z358.1 also recommends equipment be installed in a brightly lit area and marked with a highly visible safety sign.

Maintenance and training

The last thing you want is to rush to the eyewash or shower, only to be drenched with nasty, sediment-laden water. ANSI recommends flushing all equipment weekly to verify proper flow, and clearing the plumbing of any deposits. If your facility does not have floor drains installed, remember to bring a large, plastic trash can to catch the water. The weekly flushing can also provide a great training opportunity to refresh the operation and travel paths for your employees.

ANSI Z358.1 FAQ: What is the Weekly Test vs. the Annual Test?

Are you unsure of when you should test the emergency showers and eyewashes in your facility? Do you know the difference between the weekly and annual testing requirements? In certain cases, a full 15-minute drench period is not required, however it is important to know what is required on a weekly basis versus annually.

ACTIVATE WEEKLY

Per the ANSI Z358.1 standard, you are required to activate the emergency equipment weekly to verify operation and to ensure there is a flushing fluid supply and clear the supply line of any sediment build-up that could prevent the flushing fluid from being delivered due to stagnant water.

How long do you activate for? ANSI states the duration of the weekly activation depends on the amount of water contained in the unit itself and all sections of pipework that are not a part of a constant circulation system, also known as the “dead leg” portions. The goal of the weekly activation is to flush out the stagnant water in the dead leg completely.

TEST ANNUALLY

All emergency eyewashes, eye/face washes, showers and combination units are required to be fully inspected annually to ensure conformance with the installation section of the Z358.1 standard for that type of equipment. The following some of the requirements that need to be met for the annual test:

  1. The equipment must be assembled and installed in accordance with the manufacturer’s instructions, including flushing fluid delivery requirement.
  2. Equipment must be accessible within 10 seconds, located on the same level as the potential hazard, and must be free of obstructions that may inhibit immediate use.
  3. Must be identified with well-lit, highly visible signage.
  4. Equipment must be connected to a supply of flushing fluid that can produce the required flush time of a full 15 minutes.
  5. Where the possibility of freezing conditions exists, equipment must be protected from freezing or freeze-protected equipment must be installed.
  6. Must deliver tepid flushing fluid for the full 15-minute drench period.
  7. Equipment must go from “off” to “one” in one second or less.
  8. Must provide a controlled flow of flushing fluid at a velocity low enough to be non-injurious to the user.

How long do you activate for? As stated above, you need to ensure the equipment is is delivering tepid flushing fluid for a full 15 minutes.

ANSI Z358.1 DEBATE: “1-Touch” vs. “1-Second” Activation

The  ANSI Z358.1 Standard (American National Standard) mandates that proper eyewash activation – which describes a unit going from “off” to “on”- shall take one second or less.  This requirement has held true since the inception of the ANSI Standard in 1981 and throughout all revisions including 1990, 1998, 2004, 2009 and 2014. Despite this, the myth that the eyewash must go from “off” to “on” in one motion continues to be inaccurately shared.

To quote the 2014 Standard: “The valve shall be simple to operate and shall go from “off” to “on” in 1 second or less.”

This disconnect in awareness of the activation requirement has come up especially pertaining to faucet-mounted eyewashes where it is required for the user to turn on the water supply and then activate the unit, hence a two motion activation.

Specifically, the Haws® AXION® eyePOD® faucet-mounted eyewash has proven through testing that it meets the “off to on in one second or less” activation requirement.

Mounting easily to standard faucets, the AXION eyePOD provides healthcare offices, laboratories, schools, and even households with medically consistent inverted eyewash flushing technology.

As seen below, a simple rotation of the unit transforms normal faucet capabilities into a fully-functioning, ANSI compliant eyewash station.

OSHA regulations vary for eyewash flushing & shower drenching

Written by: Wesley J. Maertz

The question often comes up as to where OSHA calls out eyewash requirements. Emergency shower and eyewash station equipment needs are referenced in two different types of OSHA regulations. The first is applicable to all general industry or construction facilities that require the installation of emergency shower or eyewash station equipment. The second type is specific to certain industries.

Both regulation types specify where and when emergency eyewash and shower equipment must be available. Neither, however, specifies minimum selection, installation, operation or maintenance requirements. For the answers to these questions, organizations must turn to the American National Standards Institute (ANSI)/ International Safety Equipment Association (ISEA) American National Standard for Emergency Eyewash and Shower Equipment standard, (ANSI/ISEA Z358.1-2014).

General applicable regulations

When working with corrosives, drenching facilities must be readily available according to 29 Code of Federal Regulations (CFR) 1910.151(c) for general industry and 29 CFR 1926.50(g) for construction industry. Both state, “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.” These drenching facilities could include an eyewash, eye/face wash, shower or combination eye/face wash shower depending on the amount of possible exposure. Because OSHA does not clarify the minimum requirements for “suitable facilities,” employers often look to the ANSI/ISEA Z358.1 Standard for Emergency Eyewashes and Shower Equipment for guidance.

Specific industry applicable regulations

There are also industry specific regulations that address emergency drenching requirements. You must be familiar with these specific requirements if they apply to your workplace:

♦ Open Surface Tanks 29 CFR 1910.124(g)(2) and(3):

“An emergency shower and eye-wash station close to the dipping or coating operation. In place of this equipment, you may use a water hose that is at least 4 feet (1.22 m) long and at least 3/4 of an inch (18 mm) thick with a quick-opening valve and carrying a pressure of 25 pounds per square inch (1.62 k/cm2) or less; and at least one basin with a hot-water faucet for every 10 employees who work with such liquids.

♦ Anhydrous Ammonia 29 CFR 1910.111(b)(10)(iii)

“Stationary storage installations shall have an easily accessible shower or a 50-gallon drum of water.”

♦ Powered Industrial Trucks 29 CFR 1910.178(g)(2)

“Facilities shall be provided for flushing and neutralizing spilled electrolyte, for fire protection, for protecting charging apparatus from damage by trucks, and for adequate ventilation for dispersal of fumes from gassing batteries.”

♦ Pulp, Paper, and Paperboard Mills 29 CFR 1910.261(g)(5)

“…A deluge shower and eye fountain shall be provided to flush the skin and eyes to counteract lime or acid burns.”

♦ Telecommunications 29 CFR 1910.268(b)(2)(i)

“…Facilities for quick drenching or flushing of the eyes and body shall be provided unless the storage batteries are of the enclosed type and equipped with explosion proof vents, in which case sealed water rinse or neutralizing packs may be substituted for the quick drenching or flushing facilities. Employees assigned to work with storage batteries shall be instructed in emergency procedures such as dealing with accidental acid spills.”

♦ Formaldehyde 29 CFR 1910.1048(i)(3)

“If there is any possibility that an employee’s eyes may be splashed with solutions containing 0.1 percent or greater formaldehyde, the employer shall provide acceptable eyewash facilities within the immediate work area for emergency use.”

Consensus applicable regulation

ANSI/ISEA Z358.1-2014 is a voluntary national consensus standard that OSHA refers employers to as a recognized source for guidance. It helps users select, install, operate and maintain emergency eye wash and shower equipment. The standard is divided into five sections and each section addresses minimum performance and use requirements, as well as installation, testing procedures, maintenance and training requirements. OSHA often uses ANSI/ISEA Z358.1-2014 as a guide during inspections and may elect to issue penalties based on non-compliance.

To ensure that eyewash stations and showers are always ready when needed, it is important that the requirements for test procedures and maintenance set forth in ANSI/ISEA Z358.1-2014 be followed. The requirements for testing and maintaining eye, eye/face washes and showers are based on the manufacturer’s instructions and ANSI protocols. Generally, the manufacturer’s instructions state that the devices should be inspected tested and the results recorded weekly. Individual owners’ manuals should be looked at for the specific manufacturer’s guidelines.

Determination of a corrosive material

Within the general guidelines, occasionally the question comes up as to whether OSHA requires eyewashes for anything other than injurious corrosive chemicals. In a May 5, 2004 letter of interpretation, OSHA states: “As the standard states, an eyewash and/or safety shower would be required where an employee’s eyes or body could be exposed to injurious corrosive materials. If none of the materials used in this work area is an injurious corrosive (as indicated by the Material Safety Data Sheet (MSDS) for each product), then an emergency eyewash or shower would not be required pursuant to 1910.151(c) and 1926(g)”

Corrosive material is present in many workplaces either by themselves or contained in other materials. It is a good idea to refer to several sources to determine if a chemical is considered a corrosive to OSHA’s definition as it applies to eyewashes.

One of the easiest ways to identify if a chemical has corrosive properties is to use OSHA’s Hazard Communication Standard (29 CFR 1910.1200) and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) as a guide.  The universal symbols/pictograms used on labels and containers provide clear indications if a chemical is a corrosive.

Another source to identify if a chemical is corrosive is the Safety Data Sheet (SDS). Section 2 of the SDS will quickly provide the same information found on the shipped container label including the pictogram and precautionary statements. Section 9 of the SDS provides more details about the physical properties of the chemical including pH, which is the measure of how basic or acidic the chemical is on a scale of 0-14. A rating below seven is more acidic and above seven is more basic.

One other source to reference is the NIOSH pocket guide. The pocket guide presents key information such as pH in abbreviated or tabular form for chemicals or substance groupings that are found in the work environment.
