Presentation Transcript

  1. Flammable and Combustible Liquids

  2. Flammable liquids • Class I - liquids have flashpoints below 100 degrees F, with vapor pressures not exceeding 40 psia • Class IA - liquids having flashpoints below 73 degrees F and boiling points below 100 degrees F 1a

  3. Flammable liquids • Class IB - liquids having flashpoints below 73 degrees F and boiling points at or above 100 degrees F • Class IC - liquids having flashpoints at or above 73 degrees F and below 100 degrees F 1b

  4. Flammable liquids • Flammable liquids give off ignitable vapors 1c

  5. Combustible liquids • Class II liquids have flashpoints at or above 100 degrees F and below 140 degrees F 1d

  6. Combustible liquids • Class III liquids have flashpoints at or above 140 degrees F • Class IIIA liquids have flashpoints at or above 140 degrees F and below 200 degrees F • Class IIIB liquids have flashpoints at or above 200 degrees F 1e

  7. Handling and storage procedures • Two forms of storage: • Reserve storage in drums • Operational storage in small quantities at work stations • Connect drums to a grounding system 2a

  8. Handling and storage procedures • Liquids can be dispensed by two methods: • Gravity flow • Pump methods 2b

  9. Handling and storage procedures • Areas where flammable liquids are transferred from one container to another must: • be protected from ignition sources • have drainage or other methods to control spills • have natural or mechanical ventilation 2c

  10. Handling and storage procedures • Store flammable liquids in approved safety cans 2d

  11. Handling and storage procedures • Flammable liquids used at workstations must not exceed the sum of: • 25 gallons of Class IA liquids in containers • 120 gallons of Classes IB, IC, II, or III liquids in containers • 660 gallons of Class IB, IC, Class II, or Class IIIA liquids in a single portable tank 2e

  12. Handling and storage procedures • Use specially designed waste cans for the disposal of waste • Remember that it is the vapors, not the liquid that burns • Use specially developed absorbent materials for spill cleanup 2f

  13. Flood emergencies If flammable liquids are stored in tanks, review and understand the location and contents of flood emergency instructions • Emergency action plans 3a

  14. Flood emergencies and storage tanks • Categories of storage tanks • Above ground • Underground • Tanks inside of buildings 3b

  15. Flood emergencies and storage tanks • Types of storage tanks • Atmospheric • Low-pressure • Pressure vessels 3c

  16. Flood emergencies and storage tanks • Keep debris and vegetation away from the tank area • Situate tanks in areas where high-level water will not occur • Anchor horizontal tanks if more than 70 percent of the tank’s capacity will be submerged 3d
