Portable Eyewash Station – OSHA Term

A portable eyewash station is a safety device required by OSHA in any workplace where corrosive chemicals are used. Its job is simple but critical: flush a person’s eyes if a foreign material like a chemical gets in them. Unlike fixed eyewash stations that connect to building plumbing, it has its own water tank. This makes it ideal for job sites without permanent water lines or for areas that move around.

OSHA treats portable eyewash stations as a serious requirement. If your workers handle bulk chemical plants materials, you need one nearby. The same goes for oil and gas facilities, petroleum refineries, and pharmaceutical manufacturing lines. For a full workplace safety setup, fall protection systems work alongside portable eyewash stations to protect your people from multiple hazards.

How a Portable Eyewash Station Works

Its comes in two main types. Each works a little differently.

Gravity-fed portable eyewash stations

• Water sits in a built-in tank above the eyewash nozzles
• Gravity pulls the water down when you activate the unit
• No pumps or electricity needed
• Water flows for about 15 minutes, which meets OSHA requirements

Pressurized portable eyewash stations

• Water is stored in a sealed tank with air pressure
• When you open the valve, pressure pushes the water out
• Water flows faster than gravity units
• Must be re-pressurized after each use

Some connect to a faucet. Others have a hand pump. But all of them do the same thing: deliver clean water to flush chemicals out of a person’s eyes. For facilities with fixed plumbing, drench showers are often installed right next to portable eyewash stations for full body decontamination.

What to Do When a Chemical Splashes in Your Eyes

Time is critical when chemicals get in your eyes. Every second counts. Here is the step-by-step procedure that every worker should memorize:

• Go immediately to the eyewash station: Do not hesitate. Do not wait for pain to start. Move fast.
• Begin to flush your eyes with water: Activate the portable eyewash station right away.
• Hold your eyes open with your fingers: Your natural reaction is to squeeze them shut. Fight that urge.
• Roll your eyes frequently: Look up, down, left, and right so water reaches every part of the eye.
• Flush your eyes for 15 minutes: This is not a suggestion. It is the minimum time required by ANSI standards.
• Remove contact lenses if you have them: Contacts can trap chemicals against your eye. Take them out during flushing.
• Seek immediate medical help: Even if your eyes feel better, see a doctor. Some chemicals cause delayed damage.

For proper chemical safety, spill containment systems and portable eyewash stations should both be present wherever hazardous chemicals are handled.

Where to Place Portable Eyewash Stations

OSHA has clear rules about where its belong. Here are the key requirements:

• Within 10 seconds of travel time from the chemical hazard
• On the same level as the work area (no stairs or ladders in between)
• In a well lit area that is easy to find
• Not blocked by equipment, pallets, or other obstructions
• Near areas where bulk chemical plants workers handle corrosives
• Close to truck loading systems where chemical transfers happen
• Accessible from loading platforms and elevated work areas

It can be moved around as needed. That is the whole point of portable. If your crew moves to a different part of the facility, take the eyewash station with them. For facilities that handle food and beverage ingredients, eyewash stations are still required even if the materials are not highly corrosive. Sanitizers and cleaning chemicals count too.

Safety Manager Checklist for Portable Eyewash Stations

Every safety manager should inspect portable eyewash stations on a regular schedule. Here is a quick checklist to use:

• Are the water jets working properly? Turn the unit on and check for strong, even spray.
• Is the water clear? Cloudy or dirty water means it is time to change it.
• Is the area obstructed? Nothing should block the path to the portable eyewash station.
• Are there any leaks? Check the tank, hoses, and nozzles for drips or cracks.
• Is the water still good? Stored water can grow bacteria. Check the label for change dates.
• Is the pressure still up? For pressurized units, make sure the gauge reads in the green zone.

Grounding and monitoring systems are another important safety check. Static electricity can ignite chemical vapors near your portable eyewash station.

Maintenance Requirements

It is no good if the water is dirty or the unit does not work. Maintenance is not optional. It is an OSHA expectation.

Weekly maintenance

• Turn on the portable eyewash station at least once a week
• Let water run through to flush out pipeline sediment
• Check for proper flow and spray pattern
• Inspect for leaks or damage

Monthly maintenance

• Check the water quality in stored water units
• Look for cloudiness, odor, or floating particles
• Test the activation mechanism
• Check pressure gauges on pressurized units

Quarterly maintenance

• Change the water in portable eyewash stations that use stored water
• Clean the tank and nozzles
• Replace any worn parts
• Update inspection records

For railcar loading areas, railcar loading systems should have portable eyewash stations within reach. Marine gangways should also have eyewash access for dock workers.

OSHA Requirements You Need to Know

OSHA does not mess around when it comes to portable eyewash stations. Here are the key rules from standard 29 CFR 1910.151(c):

• Eyewash stations are required wherever corrosive chemicals are used
• They must be readily accessible to workers
• They must provide a continuous flow of water for at least 15 minutes
• The water must be clean and flushing fluid must be potable
• Workers must know where the stations are located
