Combustible dust services
Simtars offers extensive testing of dusts to help you better design and install equipment used in areas where combustible dust poses an explosion or fire hazard.
We have more than 20 years of experience working with design engineers, equipment suppliers and hazardous area consultants in government, universities and mining, and in a wide range of industries such as metal processing, food products, pharmaceuticals and chemicals.
Materials we can test
We can test all dusts, including metal powders, foodstuffs, wood dust, coal dust and waste residue.
We do exclude some materials that may be hazardous to our staff or the equipment (e.g. powders that generate highly corrosive acid gases in the explosion tests).
