In 2011 someone wrote to OSHA and specifically asked for clarification on the use of the words “or” and “nor” in the paragraph Design, Construction, and Capacity of Storage Cabinets-Maximum Capacity, 1910.106(d)(3)(i), which states: “Not more than 60 gallons of Class I or Class II liquids, nor more than 120 gallons of Class III liquids […]
An investigation into an explosion last year at a fertilizer plant has been completed by the State Fire Marshal’s Office and the report reads like a classic flammable liquid explosion – one small problem, Triclopyr 3 is not a flammable liquid! Triclopyr 3 has a flash point of 141°F and in today’s GHS world that
A major hazard involved with the transfer of non-conductive flammable liquids is the build-up of static electricity with the potential for discharge resulting in fire and subsequent loss of primary containment, an LOPC event. Certain non-polar liquids can be charged (e.g., while flowing through pipes and hoses). Detectable and hazardous charges must be expected if
This month we saw CAL-OSHA issue citations to a roofing company after two of its employees were literally blown off an asphalt tanker and ten (10) feet to the ground. Both workers sustained serious burns to large portions of their bodies. But after hearing all the comments about “safety is just common sense” I wonder
It appears OSHA is getting serious about 1910.106(e)(2)(ii)(b)… 1910.106(e)(2)(ii) “Containers.” flammable liquids shall be stored in tanks or closed containers. 1910.106(e)(2)(ii)(a) Except as provided in subdivisions (b) and (c) of this subdivision, all storage shall comply with paragraph (d) (3) or (4) of this section. 1910.106(e)(2)(ii)(b) The quantity of liquid that may be located outside of an inside storage
The existing PSM standard applies in part to processes involving a flammable liquid or gas on site in one location in a quantity of 10,000 pounds or more. However, the existing PSM standard contains an exemption for “[f]lammable liquids stored in atmospheric tanks or transferred which are kept below their normal boiling point without benefit
Back on March 4, 2016 a contractor/truck driver was transferring “diesel fuel” of some type from a storage tank to his truck when there was a flash fire. He received 2nd and 3rd degree burns over 50% of his body and has since passed away from his injuries. When I saw this incident in my
Yes, OSHA has rules for the use of flammable liquids in areas that are not designed as a Hazardous Location. OSHA covers Hazardous Locations in 1910.307, but those areas that do not rise to the level of being a Hazardous Location fall under 1910.334(d) which states:
This is an excellent photo that shows what happens when a FLAMMABLE LIQUIDS ATMOPSHERIC STORAGE tank does not have proper or adequate emergency venting. As we can see in this photo (Source: AP) the tank is still in tank, but with a large hole (e.g. new vent!). This tank was estimated to have reached the
OSHA, as well as NFPA and IFC, permit a “weak roof-to-shell seam” as the means for emergency venting on an OUTSIDE ABOVE GROUND ATMOSPHERIC storage tank for flammable liquids. This method was vey common in the early days, but has since been replaced with engineered fire vents. This video does an excellent job demonstrating how
