* Chemical & Petrochemical
The chemical and petrochemical sector relies on the efficient transportation, handling and processing of many hazardous and highly flammable chemical products.
Supply chain activities like the transfer of chemicals to and from tank trucks and railcars; filling, mixing and blending in drums or IBCs, and minor operations like dispensing solvents from safety cans generate hazardous levels of static electricity. The most effective static control solution of eliminating the risk of fires and explosions caused by static electricity is to use modern fit for purpose static control equipment.
* Food & Beverage:
The handling and storage of combustible organic ingredients like flour or sugar, and flammable products like ethanol, generate dangerously high levels of static electricity.
According to a report published by the IChemE 36% of industrial fires occur in bakeries. As more attention is paid to potential dust cloud explosion hazards and flammable hazards by government regulators, (ATEX & OSHA) the food and beverage industry is increasingly turning its attention to managing the risks associated with static electricity in potentially flammable and explosive atmospheres.
* Paints & Coatings
Solvents and combustible organic powders are heavily utilised constituents of decorative and protective paints and coatings.
Although more stringent VOC targets are in place, the use of solvents is still important in aerospace, marine, electronics and general industrial protective coating applications. The milling, grinding and extraction of organic powders and mixing and blending of solvents can generate hazardous levels of static electricity and this risk must be managed effectively through the application of fit for purpose grounding and bonding static control equipment.
The pharmaceutical industry has a long history of worker safety and fire prevention, and has made significant strides in static control solutions which eliminate static hazards within dangerous process environments.
Milling and grinding operations, dust collection, container filling and general movement of combustible powders and solvents are significant sources of static electricity. After mechanical spark ignitions, uncontrolled discharges of static electricity are the highest reported source of ignition in combustible dust cloud explosions
