Flammable Liquids

Does OSHA require introduction of fresh air for flammable liquid handling areas? (1910.106(e)(2)(iii)

OSHA’s says No; 1910.106(e)(2)(iii) does NOT require the exclusive use of fresh air for ventilation purposes.  OSHA states that 1910.106(e)(2)(iii) is a performance requirement and does NOT explicitly require the introduction of fresh air to meet the performance requirements of the OSHA standard.

Transferring non-conductive flammable liquids

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…...
