    Study Notes

    Flammable and Combustible Liquids Overview

    • Flammable Liquids: Ignite easily with flash points below 100°F (38°C).
    • Combustible Liquids: Require higher temperatures to ignite, flash point above 100°F (37.8°C).

    Key Terms and Definitions

    • Boiling Point: Temperature where a liquid transitions to vapor; important for categorizing flammable liquids.
    • Flash Point: Lowest temperature at which a liquid generates ignitable vapors; crucial for assessing fire risk.
    • Bonding: Connecting two electrically conductive objects to equalize static charges; often done during liquid transfers.
    • Grounding: Connecting a conductive object to the ground to dissipate static electricity.

    Categories of Flammable and Combustible Liquids

    • Category 1 Liquids: Flash point <73.4°F (23°C) and boiling point ≤ 95°F (35°C).
    • Category 2 Liquids: Flash point <73.4°F (23°C) and boiling point > 95°F (35°C).
    • Category 3 Liquids: Flash point ≥73.4°F (23°C) and boiling point ≤ 140°F (60°C).
    • Category 4 Liquids: Flash point ≥140°F (60°C) and boiling point ≤ 200°F (93°C).

    Classes of Combustible Liquids

    • Class II: Flash point between 100°F (37.8°C) and 140°F (60°C); most dangerous class of combustible liquids.
    • Class III: Flash point ≥140°F (60°C); includes subclasses IIIA (140°F to 200°F) and IIIB (≥200°F).

    Safety Measures and Equipment

    • Closed Piping Systems: Minimize airflow and vapor formation, reducing fire risks during liquid transport.
    • Safety Cans: Hold 1-5 gallons of liquid; must include safety features like venting and flame arresters.
    • Storage Cabinets: Must have a three-point locking mechanism, labeled, and designed to store flammable materials safely.

    Regulations and Compliance

    • OSHA Standards: Mandate that facilities storing over 25 gallons of flammable liquids must have approved storage rooms equipped with ventilation.
    • Safety Data Sheets (SDS): Provide crucial information on hazards, risks, and handling for flammable liquids; required in workplace settings.

    Fire Control and Prevention

    • Ignition Sources: Include sparks, open flames, and hot surfaces; essential to manage to prevent fires.
    • Fire Prevention: Involves storing flammable liquids away from heat sources and ensuring proper container labeling.
    • Control Mechanisms: Safety vents help prevent explosion risks by releasing pressure build-up in containers.

    Important Practices to Follow

    • Disposal Methods: Use waste drums and safety disposal cans specifically designed for flammable substances.
    • Employee Training: Employers are responsible for educating workers on safe handling and storage practices of flammable and combustible liquids.
    • Hazard Communication: Involves informing employees about potential risks and ensuring proper labeling is visible on all containers.

    Key Challenges and Considerations

    • Chemical Reactions: Certain chemicals can react violently with water; proper extinguishing methods must be identified.
    • Static Electricity: A significant ignition source; bonding and grounding can help mitigate risks.
