7.9 Corrosives<br />
OSHA defines a corrosive as “a chemical that causes visible destruction of, or irreversible<br />
alterations in living tissue by chemical action at the site of contact.” Under the DOT Hazard<br />
Class system, corrosives are listed as Class 8.<br />
Corrosive chemicals can be further subdivided as acids and bases. Corrosives can be in a liquid,<br />
solid, or gaseous state. Corrosive chemicals can have a severe effect on eyes, skin, respiratory<br />
tract, and gastrointestinal tract if an exposure occurs. Corrosive solids and their dusts can react<br />
with moisture on the skin or in the respiratory tract and result in exposure.<br />
Whenever working with concentrated corrosive solutions, splash goggles should be worn instead<br />
of safety glasses. Splash goggles used in conjunction with a face shield provides better<br />
protection. Please note that a face shield alone does not provide adequate protection. Use of<br />
rubber gloves such as butyl rubber and a rubber apron may also be required.<br />
Corrosive chemicals should be handled in a fume hood to avoid breathing corrosive vapors and<br />
gases.<br />
When mixing concentrated acids with water, always add acid slowly to the water (specifically,<br />
add the more concentrated acid to the dilute acid). Never add water to acid, this can result in a<br />
boiling effect and cause acid to splatter. Do not pour the acid directly into the water; it should be<br />
poured in a manner that allows it to run down the sides of the container. Never store corrosive<br />
chemicals above eye level and always use a protective bottle carrier when transporting corrosive<br />
chemicals.<br />
Some chemicals can react with acids and liberate toxic and/or flammable vapors. When working<br />
with corrosive materials, ensure that the proper amount of spill cleanup material is available for<br />
neutralization, such as Calcium carbonate for acids and Citric acid for bases. Contact your EHS<br />
Office for assistance.<br />
Wherever acids and bases are used, an eyewash and emergency shower must be available. If any<br />
corrosive chemical gets splashed in the eyes, immediately go to an eyewash station and flush<br />
your eyes for at least 15 minutes. The importance of flushing for at least 15 minutes cannot be<br />
overstated! Once the eyewash has been activated, use your fingers to hold your eyelids open and<br />
roll your eyeballs in the stream of water so the entire eye can be flushed. After flushing for at<br />
least 15 minutes, seek medical attention immediately and complete an Injury/Illness Report.<br />
For small splashes of corrosives to the skin, remove any contaminated gloves, lab coats, or other<br />
clothing, and wash the affected area with soap and water for at least 15 minutes. Seek medical<br />
attention afterward, especially if symptoms persist.<br />
For large splashes of corrosives to the body, it is important to get to an emergency shower and<br />
start flushing for at least 15 minutes. Once under the shower, and after the shower has been<br />
activated, it is important to remove any contaminated clothing. Failure to remove contaminated<br />
clothing can result in the chemical being held against the skin and causing further chemical<br />
