Notes

List three essential rules of lab safety.
a. Use appropriate safety equipment and gear. This includes wearing safety goggles, lab coats, gloves, and other protective gear as necessary for the specific experiments being conducted.

b. Try to prevent and report any spills or accidents immediately. If a spill or accident occurs, it's important to clean it up safely and report it to your supervisor or instructor promptly.

c. Know the location of safety equipment and emergency exits. Familiarize yourself with the locations of fire extinguishers, eyewash stations, emergency showers, and emergency exits in the laboratory to be prepared in case of an emergency.



2.) List 8 general rules for safely handling chemicals in the lab.
a. Read and understand labels: Always read chemical labels carefully before using a substance. Pay attention to hazards, handling instructions, and storage requirements.

b. Wear appropriate personal protective equipment (PPE): Wear the necessary PPE, including safety goggles, lab coats, gloves, and closed-toed shoes to protect yourself from chemical spills and splashes.

c. Work in a well-ventilated area: Ensure proper ventilation in the laboratory to minimize exposure to fumes and vapors. Use fume hoods when working with volatile or toxic chemicals.

d. Label all containers: Clearly label all containers with the name of the chemical, date, and any relevant hazards. Never use an unlabeled container.

e. Use the smallest amount necessary: Minimize the quantity of chemicals you handle. Only use the amount required for your experiment, and never return excess chemicals to their original containers.

f. Handle chemicals with care: Pour chemicals slowly and carefully to avoid spills. Always add acids to water, not the other way around, to prevent splattering.

g. Know emergency procedures: Familiarize yourself with the lab's emergency procedures, including the location of safety equipment, emergency showers, eyewash stations, fire extinguishers, and evacuation routes. Know how to respond to chemical spills and accidents. Additionally, always follow the specific safety guidelines and protocols provided by your instructor or lab supervisor, and seek their guidance if you are uncertain about the safe handling of a particular chemical or procedure.

h. No eating, drinking, or applying cosmetics: Do not eat, drink, or apply cosmetics in the laboratory. Contaminated hands can transfer chemicals to your mouth or eyes.

3.) List 6 general rules for fire and glass safety.

a. Keep flammable materials away from open flames: Store flammable chemicals and materials in designated storage areas away from open flames, heat sources, and electrical equipment. Ensure that flammable liquids are properly capped when not in use.

b. Know the location of fire extinguishers: Familiarize yourself with the location of fire extinguishers in the laboratory and understand how to use them. Different types of fires require different extinguishing agents, so use the appropriate one.

c. Handle glassware with care: Inspect glassware for cracks, chips, or defects before use. Do not use damaged glassware, as it may break during use. Handle glassware gently to avoid breakage.

d. Use appropriate equipment for glassware: Use tongs, clamps, and other appropriate tools when handling hot glassware. Never pick up hot glassware with your hands. When heating glassware, use a Bunsen burner or heating mantle with caution.

e. Label and store chemicals properly: Store chemicals in containers that are resistant to breakage, and label them clearly. Do not use glass containers that are not designed for chemical storage. Store chemicals away from the edges of shelves to prevent accidental breakage.

f. Clean up broken glass immediately: If glassware breaks, immediately clean up the broken pieces using a broom and dustpan or other suitable equipment. Dispose of broken glass in designated containers. Be cautious when handling broken glass to avoid cuts.

These rules are important for maintaining a safe laboratory environment and reducing the risk of fires and glass-related accidents. Always follow the specific safety guidelines and protocols provided by your instructor or lab supervisor.

4.) Know where fire extinguisher is located and how to use it
