In the event of a chemical exposure burn, it’s crucial that the eyes are irrigated as quickly as possible to minimise tissue damage. Staff who can flush their eyes with water within 10 minutes of the injury occurring will suffer less severe injuries with shorter periods of hospitalisation required. In this post, we explain how to use an eyewash station to treat chemical burns in the workplace.
Chemical burns can occur in a multitude of work settings including laboratories, decanting areas, construction sites, commercial vessels, oil and gas refineries and food manufacturing plants. While hazardous liquids splashing over the face are the most common type of injury, chemical burns also happen when toxic and corrosives dusts/powders are blown into the eyes.
Examples of chemical burns may include:
To protect your team from the eye damage from chemical exposure, we recommend always carrying out a risk assessment at your site. This risk assessment will help you determine the ways in which workers could suffer eyes injuries — and the likelihood of it happening. A risk assessment will also guide you as to whether your workplace actually requires an eyewash station.
Once your risk assessment is complete, you can then make sure your eye wash stations are installed key locations that could best serve injured workers. Refer to the eyewash station requirements under WHS laws and the Australian Standards to assist with your installation of the emergency decontamination equipment.
IMPORTANT: The eyes are soft tissue organs and very vulnerable to trauma, so never use emergency showers and drench hoses to flush the eyes. Dedicated eyewash units, that are manufactured to Australian Standards, regulate water pressure, so the decontamination process is safe for the eyes.
The chemical emergency eyewash procedure involves the prompt irrigation of the eyes after chemical exposure. Activate the eyewash station and hold the eyelids open while the water washes the eyeballs. To ensure that all chemicals are removed from the eye, gently roll your eyeballs in all directions and allow the water to irrigate beneath the eyelids. Emergency eyewash stations provide a steady stream of water for both eyes, so make sure that both eyes are decontaminated, regardless of whether you believe it’s one or two eyes that have been affected. If you wear contact lenses, don’t try to remove them prior to flushing. Activate the eye wash station as soon as possible then remove contact lenses as you continue to irrigate the eyes.
To reduce the risk of permanent eye injuries, make sure that you rinse the eyes for at least 15 minutes before seeking emergency medical attention.
Sufficient irrigation of the eye through the use of an eye wash station is required to reduce the risk of permanent eye damage.
IMPORTANT: When there’s chemical exposure in the workplace, other hazards can also be present. When making your way to the emergency eyewash facility, beware of peripheral hazards like slippery floors, dropped PPE, or chemical residues that might contact other body parts (or first aiders).
Training and emergency drills are essential in helping staff understand how to effectively use eyewash equipment. Create standard operating procedures for the emergency eyewash station and drill staff on the procedure for tending to a chemical burn.
The following are some basic steps that may be required for emergency decontamination of the eyes:
The usage instructions above are generic, so only use them as the basis for your own work procedures. Emergency eyewash procedures should always be developed to meet the specific chemical hazards located at your own job site.
Imagine installing an eyewash facility, only to have the equipment not working correctly (or being complexly inoperatable) when you’re faced with a chemical emergency.
Here’s our 3 workplace essentials for making sure that never happens:
It’s an essential requirement under AS 4775-2007 - Emergency eyewash and shower equipment to ensure your eyewash station is properly maintained.
Plumbed eyewash stations must be activated at least once a week to verify they are operational, plus clear the water supply line of any buildup of sediment. This also minimises the likelihood of stagnant water and an accumulation of microbial contaminants.
Both plumbed and self-contained eyewash stations must be inspected and tested each year by a technician who is qualified to certify and tag the units.
Self-contained eyewash equipment (which have their own limited supply of flushing fluid) require regular monitoring to ensure the flushing fluid remains intact.

If you’ve had a chemical emergency and had to use your eyewash equipment, it’s essential that the unit is cleaned as soon as possible. Make sure that all chemical residues are removed, this includes the paddle levers, both water nozzles, and covers.
At the same time, activate the unit to make sure that it’s still fully operational.
For self-contained emergency eyewash units, you’ll need to determine their suitability for reuse and then refill the tank.
Eyewash stations are exclusively for use during an emergency — they must never be used for another purpose. Using the facility as a common hand-wash area (or for other non-emergency tasks) could expose the unit to unnecessary wear or cause damage/contamination to the unit.
Create standard operating procedures so that you can train staff and contractors to use the equipment correctly. Make sure supervisors or team leaders are enforcing this requirement.
Training and induction programs should have specific content stipulating that eyewash stations are NOT:
Remind your staff that chemical emergencies can happen on any shift at any time. No one wants to be responsible for a staff member suffering a permanent injury simply because the emergency eyewash unit wasn’t maintained and used as it should be.

How to select and use compliant emergency showers and eyewash equipment is an excellent resource that will help you determine the eyewash unit that will best suit your safety and compliance requirements.
