Protective Eyewear for Chemical Work

Chemical splashes, dust and vapors can harm the eyes quickly. This guide explains how to think about eye protection for chemical work and where to find the specific requirements for your products.

Why do the eyes need extra protection?

Eyes absorb and react to chemicals very quickly, and an injury can be lasting. Splashes during mixing, pouring and spraying are a common cause, and so are dust and wind-blown droplets.

Prevention is far better than treatment, because once a chemical reaches the eye, the damage may already be underway.

Eye protection should be treated as a normal part of the job and not as something to put on only for the worst products.

What types of eyewear are there?

Eyewear ranges from safety glasses to sealed goggles to face shields worn with other protection. They guard against different hazards, and one type does not do the work of another.

Which type suits a task depends on the product and the way it is used. This site does not provide ratings or standards, because the label and safety data sheet say what the product requires, and manufacturers can explain how their equipment is rated.

Ask the maker how a given product is intended to be used, and try it on with the other protection you will wear, such as a respirator or hat.

• Safety glasses guard against flying particles.
• Sealed goggles guard against splashes, vapors and dust.
• Face shields add coverage for the face and are worn with other eye protection.

How do I find out what I need?

Read the protective equipment section of the label and the safety data sheet. For pesticides, the label is the legal document, and it names the protection that must be worn.

Ask your supplier, your extension educator or OSHA if anything is unclear. Do not choose eye protection on price or looks alone, and do not assume ordinary sunglasses or prescription glasses are enough.

Keep the label's wording handy when you shop, so you can ask a supplier exactly what the product requires.

How can I get a good fit and stay comfortable?

Protection only works if it fits and if people wear it. Goggles that fog, slip or pinch will be pushed up or taken off at the worst time, so try different options and ask workers what they will actually wear.

If you wear prescription glasses, ask about options that go with or over them. An eye care professional can help with the fit, and employers may need to provide suitable protection for workers who need corrective lenses.

How do I care for eyewear?

Clean eyewear as the maker directs and store it where it will not be scratched, crushed or covered in dust. Scratched, cracked, cloudy or deformed lenses and straps should be replaced.

Do not share eyewear between people with an infection, and do not use equipment that has been soaked in a chemical it was not meant for. When in doubt, replace it.

• Replace scratched or cloudy lenses.
• Clean as the maker directs.
• Store where it will not be crushed.

What should be nearby when working?

Protection prevents most splashes, but it does not eliminate them. Know where eye flushing equipment is and make sure the safety data sheet is easy to find. See the article on eye wash stations for general planning guidance.

Never work alone with hazardous chemicals if you can avoid it, and make sure a phone is within reach. If a chemical gets into an eye, the situation is an emergency: call 911 or follow the safety data sheet, and get medical care.

Keep a clean pair within reach of the mixing and loading area so that eyewear is never an excuse to skip the job.

Who is responsible for providing eye protection?

Employers have duties around protective equipment, and those duties depend on the type of work and on the rules that apply. Check with OSHA and your state agency about what applies to your operation.

Even where rules do not apply, a family farm can set its own standard. Keep spare eyewear in the shop and the pesticide area so that no one is tempted to skip it because theirs is missing. Make a habit of checking eyewear at the start of every job, just as you would check a hose or a hitch. It takes seconds, and it is much easier to notice a crack or a missing strap at the shop than out in the field.
