Study Notes
Chemical Spill Handling
- Immediate action: Evacuate the area, prevent access, and assess the situation.
- Personal safety measures: Use safety goggles, gloves, and lab coats; ensure proper ventilation.
- Cleanup procedures: Contain the spill using absorbent materials, neutralize if necessary, and dispose of waste appropriately.
- Safe chemical working principles: Use appropriate protective apparel to minimize exposure; helps in managing spills effectively.
Fire Safety Hazards
- Common hazards: Flammable liquids, reactive chemicals, and ignition sources.
- Types of extinguishers:
- Class A: For ordinary combustibles (wood, paper).
- Class B: For flammable liquids (oil, gasoline).
- Class C: For electrical fires (electrical equipment).
- Usage procedures: Aim at the base of the fire, use a sweeping motion, and maintain a safe distance.
Safe Storage of Hazardous Chemicals
- Effective storage methods: Use compatible containers, store in designated areas, and implement ventilation systems.
- Comprehensive storage plan:
- Compatibility: Keep incompatible chemicals apart.
- Labeling: Clearly label all containers with contents and hazards.
- Containment strategies: Utilize secondary containment for spills.
Mercury and Biohazard Cleanup
- Procedures for mercury: Never use a vacuum; use specialized tools and follow guidelines for cleanup and disposal according to regulations.
- Biohazard disposal: Utilize biohazard waste containers and follow protocols for sharps and biological waste.
Proper Labeling of Chemical Containers
- Steps for labeling: Include chemical name, concentration, hazard symbols, and date of receipt.
- Importance of accurate labeling: Essential for preventing accidental exposure and ensuring proper handling during emergencies.
Safe Disposal of Hazardous Chemical Waste
- Segregation: Separate hazardous waste by chemical compatibility and types.
- Identification: Clearly mark waste containers with contents and hazards.
- Transportation: Follow regulations for the transport of hazardous waste to disposal facilities.
Chemical Terminology
- Corrosive: Can damage tissues (e.g., sulfuric acid); requires protective gear.
- Flammable: Easily ignites (e.g., acetone); stored away from heat sources.
- Toxic: Harmful if ingested or inhaled (e.g., arsenic); use fume hoods and PPE.
Storage Safety Measures
- Key measures: Store chemicals in appropriate conditions, use cabinets for flammables, and maintain clear aisles.
- Accident prevention: Reduces risks of spills, reactions, and exposures, ensuring a safer work environment.
Material Safety Data Sheet (MSDS)
- Primary features: Chemical identity, hazards, handling instructions, and emergency measures.
- Usage: Refer to MSDS for safe handling, first aid, and cleanup for chemical-related incidents.
General Laboratory Safety Guidelines
- Always wear appropriate PPE, know the location of safety equipment, and maintain a clean work area.
- Report spills or accidents immediately, and never eat or drink in the lab to prevent contamination.
Handling Glassware and Chemicals
- Correct procedures: Always handle glassware with care, check for cracks, and avoid overcrowding workspaces.
- Risks of improper handling: Can cause cuts, spills, and chemical reactions; follow safety practices like stable setups and using appropriate equipment.
