Study Notes

Laboratory Safety and Rules

Fume Hood: Protects against inhaling hazardous substances.
- Safety Instructions: Proper use depends on the hazard level of chemical substances.
  - Avoid storing primary containment of explosive reactions.
  - Keep the fume hood clean and organized.
  - Keep the sash at the recommended height for proper airflow.
- Maintenance: Daily, periodic, and annual inspections are required.
Eye Wash Station: Used when chemicals splash into the eyes.
- Safety Instructions: Rinse open eye for 15 minutes. Remove contact lenses.
- Maintenance: Checked weekly and annually.
Safety Shower: Used for large chemical spills on a person.
- Safety Instructions: Remove contaminated clothing and run under cold water for 15 minutes.
- Maintenance: Checked weekly and annually.
Flammable Storage Cabinet: Protects against fire.
- Safety Instructions: Clearly label the cabinet and store only flammable materials. Separate incompatible substances to prevent reactions.
- Maintenance: Daily, weekly, and annual inspections are required.
- Examples of Stored Chemicals: Propane, methane
Acid Bottle Carriers: Used to safely transport and handle acid containers.
- Safety Instructions: Use appropriate PPE like gloves and goggles to protect against spills/splashes. Never pick up by the cap or lid.
- Label bottles with chemical name: Examples of acids are hydrochloric acid (HCl), sulfuric acid (H₂SO₄), nitric acid (HNO₃), acetic acid, and phosphoric acid.
Safety Cans: Used to store and dispense flammable, corrosive, and hazardous chemicals.
- Safety Instructions: Store only flammable liquids. Label the can with content details. Keep cans tightly closed when not in use.

Laboratory Safety Equipment

Fume Hoods: Protect from hazardous substances inhalation, keep clean and organized, keep sash at recommended height for proper airflow
Eye Wash Station: For chemical splashes to the eyes, rinse for 15 minutes, remove contact lenses, check weekly and annually
Safety Shower: Used for large chemical spills on a person, remove contaminated clothing, run with cold water for 15 minutes, check weekly and annually
Flammable Storage Cabinet: Separates flammable chemicals from other hazardous materials, prevent fire, label it clearly and only store flammables, keep incompatible substances separate, regular maintenance
Acid Bottle Carriers: Safely transport and handle acid containers, prevent spills and injuries, use PPE, label the container, never pick up by the cap
Safety Cans: Store and dispense flammable, corrosive, and hazardous chemicals, reduce risk of spills and fire, label the can, keep tightly closed when not in use
