Glassware Safety 1. Don’t get cut - it hurts you and your productivity. 2. Don’t drop glassware - avoid the bruises that lead to breakage. 3. Don’t use chipped or broken glassware - it’s dangerous and breraks more readily. 4. Don’t mouth pipet - you could inhale a toxic substance, burn your mouth, or cut your lip. 5. Don’t leave pipets sticking out of beakers or flasks - it’s an invitation for an accident. 6. Insert tubing carefully. Use a protective towel for your hand and lubricate the tubing. 7. Dispose of broken glassware in a special receptacle. 8. Carry large containers carefully, using a bottle carrier. 9. Clean and rinse glassware very well with deionized water, then let it dran dry on a clean, lint-free towel. To back up the rules, you need a formal laboratory safety program.
