Lab Safety Guidelines

Introduction

• Lab environments are inherently hazardous.
• Your safety is determined by your awareness and adherence to safety rules.

Proper Dress in the Lab

• Importance of Clothing:
  • Clothing helps prevent serious injuries from chemical exposure.
  • Best practice: Wear clothes that cover your entire body.
• Recommended Attire:
  • Long pants and closed-toed shoes.
  • Avoid shorts and sandals.
  • Remove jewelry and tie back long hair.
• Personal Items:
  • Bring only what is necessary into the lab.
  • Leave personal items (backpacks, purses, jackets) outside to prevent contamination.

Personal Protective Equipment (PPE)

• Required PPE for General Lab Work:
  • Lab coat (buttoned, cuffs tucked into gloves).
  • Safety glasses or goggles (goggles recommended for splash hazards).
  • Gloves (specific to the chemicals handled).
• Types of Gloves:
  • Non-absorptive gloves that resist chemicals.
  • Change gloves frequently to minimize chemical exposure.
  • Thermal and puncture-resistant gloves for extreme temperatures or handling sharps.

Additional Safety Measures

• Respirators:
  • Required for chemicals producing dangerous vapors.
  • Must complete proper training (consult lab manager or instructor).
• Hygiene Practices:
  • Remove PPE and wash hands before leaving the lab.
  • Avoid touching surfaces (light switches, doorknobs, phones) while still wearing gloves to prevent contamination.

Conclusion

• Wearing appropriate clothing and PPE minimizes exposure risks.
