B. General Safety Procedures<br />

1. BASIC SAFETY RULES FOR ALL UNDERGRADUATE LABORATORIES<br />

(prepared by Chemistry Department Faculty members)<br />

Read these safety regulations <strong>care</strong>fully, and be sure you understand them. Be<strong>for</strong>e each laboratory<br />

session, your instructor will discuss any safety hazards that might be associated with that day's experiment.<br />

1. Report all accidents to your instructor immediately. If you cut or burn yourself or accidentally<br />

inhale fumes, notify your instructor at once. The instructor will arrange immediate treatment.<br />

Learn the locations <strong>of</strong> the fire extinguishers, the safety showers, the fire blanket, eyewash, and<br />

phone, so that you can use them quickly in the case <strong>of</strong> an emergency. Your lab instructor will<br />

point out the emergency exits/routes out <strong>of</strong> Salem Hall in the case <strong>of</strong> an emergency.<br />

2. Wear safety goggles/glasses in the laboratory at all times. Always wear eye covering that will<br />

protect your eyes against both impact and splashes. (If you should get chemical in your eye, wash<br />

the eye with flowing water from the special eye-wash fountain <strong>for</strong> 15 to 20 minutes).<br />

3. Do not per<strong>for</strong>m any unauthorized experiments!<br />

4. Do not use mouth suction to fill pipettes with chemical reagents. (<strong>Use</strong> a suction bulb to fill<br />

pipettes).<br />

5. Exercise great <strong>care</strong> in noting the odor <strong>of</strong> fumes and avoid breathing fumes <strong>of</strong> any kind. Carry out<br />

experiments that produce noxious vapors in your fume hood. Arrange your apparatus setups so<br />

that the fume producing portion is inside the hood.<br />

6. Do not taste anything in the laboratory. (This applies to food as well as chemicals. Do not use the<br />

laboratory as an eating place; never eat or drink from laboratory glassware.)<br />

7. Confine long hair whenever you are in the laboratory.<br />

8. Place all hot glassware on a mat to cool; this will also signify to all laboratory personnel that the<br />

glassware is hot. Do not hand hot glassware to another person, because a person's natural instinct<br />

is to reach <strong>for</strong> it.<br />

9. Corrosive acids and bases are very soluble in water. If either a corrosive acid or base comes in<br />

contact with your skin, you can wash it <strong>of</strong> your skin be<strong>for</strong>e damage is done. Haste in washing the<br />

affected area is essential. Summon the laboratory instructor if you spill a corrosive acid or base<br />

on your skin. If strong acids are spilled on your skin, bathe the skin with dilute sodium<br />

bicarbonate after flooding with water <strong>for</strong> about 10 minutes. If strong bases are spilled on the skin,<br />

bathe the skin with a dilute solution <strong>of</strong> acetic acid or boric acid after flooding <strong>for</strong> about 10 minutes.<br />

If chemicals get into your eyes, immediately wash the eyes with a gentle stream <strong>of</strong> water from the<br />

eye wash <strong>for</strong> 15-20 minutes. Do not use dilute solutions <strong>of</strong> sodium bicarbonate, acetic acid, or<br />

boric acid in the eyes. After flushing with water, the student will be transported to the Student<br />

Health Service. If bromine or iodine is spilled on the skin, the skin should be immediately bathed<br />

with alcohol (ethanol) and then with glycerin.<br />

10. If you are preparing a dilute acid solution, never pour water into concentrated acid. Always pour<br />

the acid into the water while stirring the water constantly.<br />
