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.
