2 versus NFPA 30The older version of OSHA’s 29 CFR –Flammable Liquids, was based upon the 1969 version of NFPA 30 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 OSHAThe title of 29 CFR has been changed from “Flammable and Combustible Liquids” to “Flammable Liquids.”The 2012 Edition of NFPA 30 has not been revised to reflect GHS guidelines.NFPA 30 continues to use the term flammable and combustible liquid and refers to “classes” of liquids.
3 NFPA 30 FLAMMABLE LIQUIDS Definitions under OSHA 1910 StandardsWhat about 1926 standards??FLASH POINT BELOW 100 DEGREES FCLASSESIA - FP BELOW 73 DEGREES BOILING POINT BELOW 100 DEGREESIB - FP BELOW 73 DEGREES BOILING POINT AT OR ABOVE 100 DEGREESIC - FP AT OR ABOVE 73 DEGREES AND BELOW 100 DEGREES
4 NFPA 30 COMBUSTIBLE LIQUIDS FLASH POINT AT OR ABOVE 100 DEGREES FCLASSESII - FP AT OR ABOVE 100 DEGREES AND BELOW 140 DEGREESIIIA - FP AT OR ABOVE 140 DEGREES AND BELOW 200 DEGREESIIIB - FP AT OR ABOVE 200 DEGREES

6 Applying the OSHA Standards What type of facility is it?What types of liquids fall under ?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 (e) Industrial Facilities
7 Storage cabinets 1910.106 (d)(3) Design, construction, and capacity of storage cabinetsSpecific 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(d)(4)"Design and construction of inside storage rooms"
11 Point of Use Procedures If handling occurs in an industrial facility, follow requirements under (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 (b)(2) addresses aboveground tanksTopics include tank design and construction, spill containment, dikes, venting, etc.
