First Aid: Chemical Exposure
Some chemicals cause burns. Others may be absorbed through skin or lungs, causing hidden damage. If possible, always refer to the particular chemical's Material Safety Data Sheet or contact the Poison Control Center (1-800-222-1222) for expert advice, In general, follow the steps below.
Step 1. Stop the source
Remove the victim from contact with the chemical spill, airborne particles, or fumes. (Wear gloves or use other safety equipment as needed to protect yourself from exposure to the chemical.)
Take off any clothes or jewelry that have been in contact with the chemical. Chemical injuries, just like heat burns, continue to worsen as long as the source is in contact with the body.
Step 2. Clear the lungs
Take the victim to fresh air. This may mean going into another room or leaving the building.
Perform rescue breathing or CPR, if needed.
Step 3. Flush the eyes
Flush the affected eye with water for at least 15 minutes. Make sure the water is cool, especially if its source is an outside hose or eyewash station.
Don't accidentally flush chemicals into an unaffected eye. Hold the head so that the injured eye is on the bottom. Flush from the nose downward.
Step 4. Clean the skin
Brush water-activated chemicals, such as lime, from the skin, instead of using water. Be careful not to brush particles into the eyes.
If the chemical does not react with water, flush the affected skin with cool water for at least 15 minutes. Make sure the water flow is not forceful enough to cause pain or break blisters.
Don't brush away chemicals with your bare hands.
When to call your healthcare provider

The Material Safety Data Sheet calls the chemical hazardous or likely to cause damage.
The container label warns of corrosive contents, which can wear away skin.
The chemical causes a large burn.
There is difficulty breathing after exposure.
Call 911 right away if the victim has:
