Review these topics, either by attending the safety lecture or by consulting written sources. Try to have something coherent to say on each topic.

The second part focuses on the logic & planning behind the rules and accepted professional lab practice.

Safety staff will be available to answer questions.

• PPE for home & hobbies

9. WASTE MANAGEMENT

• Sharps
• Hazardous waste chemicals
• Waste bottles
