Use Chemical Properly Return classroom reagents to their shelf when done weighing or pouring. Use care to prevent contamination: Never return chemicals to the bottles from which they came. Pour out only what you need. Never leave a reaction or heat source unattended!

Dispose of Chemicals Properly Chemicals should be disposed of properly in the disposal hood. - Read the labels carefully before pouring chemicals in bottles. - Solid waste goes in a bucket. - Broken glass should be put in the wastebasket. - NEVER pour anything down the drain without your instructor's permission

Accidents Happen: Clean them Up Never use cracked or chipped glassware. Clean up broken glass promptly and carefully. Tell your instructor if.... Any accidents occur. Any skin contact with chemicals occurs - wash with large volumes of water. Any chemical spills occur.
