Cleaning small parts and portable equipment with solvents, either using an automatic device or manual cleaning, is a potentially extremely hazardous task relative to static generation and spark ignition of solvent vapors.  Significant static electricity charging can occur during cleaning by contact and separation resulting from the following activities: Solvent spraying, which can involve high liquid…...

One option for mitigating the static hazards associated with low conductivity liquids is to raise the conductivity of the liquid. This can be accomplished by either blending the low conductivity liquid with a conductive liquid (e.g., alcohol, ketone) or by adding a static dissipating additive into the low conductivity liquid.   When blending a low…...

Toluene is a widely used low conductivity flammable liquid. Toluene’s vapor pressure is such that one is assured of a flammable vapor/air mixture at the ambient temperatures found in most facilities. The Lower Explosive Limit (LEL) of toluene is 1% and is reached at a temperature of 40°F (4°C). The Upper Explosive Limit (UEL) is…...

Improper handling of low conductivity liquids is a source of static energy that causes flammable vapor ignition. Low conductivity liquids will accumulate a static charge from liquid shear charging at the pipe or vessel wall.  The charge in a low conductivity liquid can NOT be dissipated by grounding. Low conductivity liquids are typically derived from…...
