What should you do if a chemical splatters into your eyes?
Correct answer: D. Flush eyes with water at the eyewash fountain for at least 15 minutes, and then report the accident for further help.
- A. The rule is to add concentrated acid to water slowly.
- B. The rule is to add water to the concentrated acid slowly.
- C. Carefully replace unused or excess chemicals into their properly labeled containers from which they came.
- D. Flush eyes with water at the eyewash fountain for at least 15 minutes, and then report the accident for further help.
- E. Dispose of chemicals in the proper places and following posted procedures. Do not return them to their original containers.
Explanation
The immediate first-aid for a chemical splash in the eyes is to flush them with a large amount of water for at least 15 minutes at an eyewash station. This dilutes and washes away the chemical to minimize damage while you seek further medical attention.

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
