5 PRINCIPLES OF SAFETY• Practice Safety
– Need to know it to practice it• Be Concerned about Others
– Just because you know doesn’t everyone knows• Understand the Hazards Associated
– Prevention is Key• Know What to do in Emergencies
– Preparation saves time in Emergencies• Report Hazards and Hazardous Conditions
– Never Leave a Hazard or Potential Hazard

PERSONAL PROTECTIVE WEAR• Lab Coats
• Safety Glasses
• Gloves
• Footwear
NOTE: Splash Goggles, Face Shields, aprons, thermal or cut restraint gloves, hearing protection, and/or respirators where dictated. RED

PROPER LAB PRACTICE• Gloves
– Must be worn only in the lab
• PPE must be worn– No good if not used
• Chemical Carriers– Always use for
glass containers
• No Food in the Lab
