• Do not use anything around or inside the equipment that may produce a flame, such as a match, a lighter, or
anything that may produce a shower of sparks, such as a grinder or power saw, unless the air is free of dust
and all dust deposits have been removed from the work area, or the work area is wet such that dust cannot be
dispersed in the air and smoldering processes from sparks cannot develop. Use brush-less electrical tools and
explosion proof flash lights, for example.
• Follow the maintenance schedule to keep equipment operating at normal conditions. This will further help to
prevent the risk of components overheating or wearing out which may lead to explosion risks.
• Always purchase replacement parts from the manufacturer or authorized dealer/distributor. Original manufac-
turers parts are designed with explosion proof features where applicable
