Because of some human factors are uncontrollable, or occasional weak awareness of prevention, may cause a fire source, here is some measures for this situation:
1. Cleaning the rust regularly and avoiding dust deposition. Heat can accumulate, it is necessary to clean up the dust in the rust collector, each shift must be blowing ash. Shot blasting machine to deal with flammable and explosive dust need to pay attention to dust shot blasting room to always keep negative pressure.
2. Shot blasting machine need to avoid the impact of sparks. Maintenance of the fire source control. In the subsequent shot blasting machine inside and outside the maintenance operations, strict control of the fire source, to prevent the line ignition, gas welding operations in the first to clear the surrounding dust, after 10 minutes operation to start the test or production, There is no smoking or other ignition nearby to prevent hot particles or sparks from being inhaled into the dust collector.
3. Grounding protection. The relevant equipment and facilities to maintain a good grounding, the grounding resistance within the 1-4fZ range, to avoid the equipment and facilities electrostatic accumulation; In addition to increase the conductivity, with conductive or conductive material instead of high insulation materials, in particular the use of anti-static filter material.
4. Shot blasting machine to use the appropriate explosion-proof glass beads or magnesium alloy pill. Shot blasting machine room should be used thick polyurethane protective plate, the outer layer should be used stainless steel layer.
In addition, enterprises need to improve the operational awareness of maintenance personnel on operation, maintenance for theoretical and practical knowledge of the training, so that employees aware of the flammability of rust and dust in the production pay close attention to the operation of filter-type dust collector Construction Method and Requirement of Steel Plate Decoration Engineering. Attention to safe production can reduce unnecessary losses, shot blasting machine reasonable use and maintenance is also very important, so that shot blasting machine in the best condition and poor state, security is self-evident.
