| Acids on the skin | Wash the affected area immediately with plenty of water, then with saturated SODIUM BICARBONATE SOLUTION and again with water |
| A. Safety Rules: Protecting yourself in the Laboratory | 1. The laboratory is a place for serious work. DO NOT ATTEMPT ANY UNAUTHORIZED EXPERIMENTATION. 2. Report all injuries- no matter how minor- to your instructor immediately. 3. Beware of hot glass. Glass cools very slowly and may be very hot without appearing so. Immediately hold the injured area under cold water or cover it with ice. 4. Do not point the test tube at the student before you or yourself when heating substances. Bubbles of vapor that form suddenly may expel the contents violently. 5. When diluting sulfuric acid, pour the acid slowly and carefully into the water, stirring constantly. NEVER ADD WATER TO ACIDS. Remember the AA rule: Add acid to water. |
| Burns by dry heat | Apply BUTESIN PICRATE ointment or any burn ointment available in the first-aid kit in the laboratory |
| Alkali on the skin | Wash the affected area immediately with plenty of water, then with 1% ACETIC ACID solution and again with water. |
| Bromine on the skin | Wash the affected part immediately with plenty of LIGHT PETROLEUM (B.P. 80˚ C) and then rub GLYCERIN well onto the skin. After a short while, remove the glycerin and apply BUTESIN PICRATE ointment or any burn ointment in the first-aid kit. |
| Sodium on the skin | If a small fragment of sodium metal can still be seen, remove it carefully with a forceps. Wash thoroughly with water; followed with 1% ACETIC ACID solution. Cover the area with GAUZE COVERED IN OLIVE OIL or ACRIFLAVINE JELLY or VASELINE. |
| Organic substances on the skin. | Wash freely with RUBBING ALCOHOL, then with SOAP and WATER. |
| Cuts | If the cut is minor, allow it to bleed for a few seconds. If the cut is caused by a glass, see to it that no glass pieces remain. Apply a DISINFECTANT and BANDAGE. For serious cuts, check bleeding by applying pressure above it (a tourniquet) . Send for a doctor at once. |
| Eye Accidents: Acid in the eyes | Wash the eye/s repeatedly with 1% SODIUM BICARBONATE solution. If the acid is concentrated, wash the eye/s with large amount of water and then with BICARBONATE solution. |
| Eye Accidents: Caustic Alkali in the eyes | Wash the eye/s with large amount of water and then with 1% BORIC ACID solution. |
| Eye Accidents: Bromine water in the eyes | Wash thoroughly with 1% SODIUM BICARBONATE solution. |
| Fires | When clothes catch fire, prevent the person from running. Let him/her roll on the floor or wrap another piece of clothing around him (a laboratory gown or blanket) to cut off the supply of oxygen. When chemicals in beakers and other containers burn, cover the mouth of the vessel with a clean damp cloth so that the flame will be put off. For larger flames, sand may be employed. It is advisable to make use of a fire extinguisher. DO NOT USE WATER. |
| Poisons: Acid | If an acid is swallowed, dilute by drinking plenty of water followed by LIMEWATER or MILK OF MAGNESIA. MILK may also be given. DO NOT GIVE ANY EMETIC. |
| Poisons: Caustic Alkali | Dilute by drinking plenty of water, followed by VINEGAR, LEMON or ORANGE JUICE. MILK may also be given. DO NOT GIVE ANY EMETIC. |
| Poisons: Salts of Heavy Metals | If a salt of heavy metal is swallowed, one may give MILK or RAW EGG WHITE. |
| Poisons: Arsenic or Mercury Compounds | Give an emetic immediately such as one tablespoonful of SALT or ZINC SULFATE in a glass of warm water. |
