Personal Protective Equipment (PPE):
- Always wear safety goggles or face shields to protect your eyes from chemicals, flying particles, or broken glass.
- Lab coats or aprons protect skin and clothing from spills.
- Use gloves to prevent exposure to chemicals, heat, or biological agents.
- Wear closed-toe shoes for foot protection from spills and dropped objects.
Material Handling
-
Chemical Knowledge:
- Understand chemical hazards (toxicity, flammability, reactivity).
- Always read labels, safety data sheets (SDS), and instructions/warnings.
Ventilation
- Fume Hoods: Use fume hoods when working with volatile or harmful chemicals to prevent inhalation.
- Lab Ventilation: Ensure adequate lab ventilation; never block vents.
Chemical Handling
