  1. FLAMMABLE AND COMBUSTIBLE LIQUIDS • LEL AND UEL (Same as LFL and UFL) • FLASH POINT • VAPOR PRESSURE • SPECIFIC GRAVITY • VAPOR DENSITY

  2. 1910.106 versus NFPA 30 • The older version of OSHA’s 29 CFR 1910.106–Flammable Liquids, was based upon the 1969 version of NFPA30 Flammable and Combustible Liquids Code. • In response to OSHA’s revised Hazard Communication standard (due to incorporation of the Globally Harmonized System [GHS]), OSHA revised 29 CFR OSHA 1910.106. • The title of 29 CFR 1910.106 has been changed from “Flammable and Combustible Liquids” to “Flammable Liquids.” • The 2012 Edition of NFPA30 has not been revised to reflect GHS guidelines. • NFPA30 continues to use the term flammable and combustible liquid and refers to “classes” of liquids.

  3. NFPA 30FLAMMABLE LIQUIDS • Definitions under OSHA 1910 Standards • What about 1926 standards?? • FLASH POINT BELOW 100 DEGREES F • CLASSES • IA - FP BELOW 73 DEGREES BOILING POINT BELOW 100 DEGREES • IB - FP BELOW 73 DEGREES BOILING POINT AT OR ABOVE 100 DEGREES • IC - FP AT OR ABOVE 73 DEGREES AND BELOW 100 DEGREES

  4. NFPA 30COMBUSTIBLE LIQUIDS • FLASH POINT AT OR ABOVE 100 DEGREES F • CLASSES • II - FP AT OR ABOVE 100 DEGREES AND BELOW 140 DEGREES • IIIA - FP AT OR ABOVE 140 DEGREES AND BELOW 200 DEGREES • IIIB - FP AT OR ABOVE 200 DEGREES

  5. OSHA 1910.106 (GHS criteria)

  6. Applying the OSHA Standards • What type of facility is it? • What types of liquids fall under 1910.106? • If it is an industrial facility, is the handling of flammable and combustible liquids a major requirement of the business process or is it incidental use? • If incidental use, then follow 1910.106(e) Industrial Facilities

  7. Storage cabinets • 1910.106 (d)(3) • Design, construction, and capacity of storage cabinets • Specific requirements on design and construction. • Must withstand a 10 minute fire test. • Not more than 60 gallons of Category 1, 2, or 3 liquids should be stored in a cabinet nor more than 120 Gallons of Category 4.

  8. Venting Flammable Liquid Cabinets • “The fittings are sometimes provided by the manufacturers due to the fact that, in a few locations in the country, local ordinances require such vents to be provided.  Therefore, the manufacturers plug these vents [with plugs] which can be removed in those few areas where such venting is required.” • Unless a municipality or other government agency specifically requires the bung to be vented, venting is not required, nor is it recommended. 

  9. Inside Storage Rooms • Design requirements for inside storage rooms: • OSHA Standards • 1910.106(d)(4) • "Design and construction of inside storage rooms"

  10. Inside Storage Rooms • Room construction (ratings, doors, etc) • Electrical Wiring • Ventilation • Clear aisles

  11. Point of Use Procedures • If handling occurs in an industrial facility, follow requirements under 1910.106(e)(6) • Why is grounding and bonding required? • For example, what categories of liquids? • What impact does using a plastic safety can have on this? • Are plastic safety cans acceptable for use in the workplace by OSHA?

  12. Aboveground Storage Tanks • 1910.106(b)(2) addresses aboveground tanks • Topics include tank design and construction, spill containment, dikes, venting, etc.
