The increasing pressure in the container can cause the contents to spray out the top, or the container shatters, spreading shards of glass
Keep Flammable Substances Away From Heat Sources
Clean up all spills immediately
1. Never return spilled or unused material to the reagent bottle.
2. Solids should be swept up and placed in the waste disposal container for that lab
3. Small liquid spills should be diluted with lotsof water and mopped up with a cloth towel.
4. Large spills must be handled by the instructor.
Begin First Aid Immediately

contact with the eyes, begin eyewashing NOW!
3. Remove clothes that have chemical contamination
4. Move everyone away from the area to avoid further contamination
Report all injuries to your
instructor immediately.
