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.
