The explosive danger rate that produces a course is the main basis that chooses measure of explosion proof technology. The category that defined volatile material only, level, group is fastened and after the area of explosive danger environment, ability decides the explosion proof step that should take accordingly. For this, must analyse the explosive danger sex that produces a course above all, undertake to product and the whole process that manufacture technology serious analysis studies. The analysis produces the dangerous sex in the process, the physics that basically is the raw material that in knowing production, uses, semifinished product and finished product, chemistry and danger are characteristic, what use dangerous material measure, the equipment type that uses in production, the craft condition such as the reaction temperature of the choice, pressure, with etc the likelihood causes all sorts of conditions with produce explosion hazardous. Normal > chooses measure of explosion proof technology, want to consider to produce the demand of craft, accomplish already economy reasonable, avoid the happening of the accident effectively or fall accident occurence rate lowermost limit, although in case produced an accident, also can limit the scope that its affect, fall the calamity of explosive accident to lowermost limit. Normal > chooses measure of explosion proof technology, still should follow the following principle: Normal >1. Trends controls principle Normal > has the system of explosive danger is athletic change, and rather than is dormant and changeless. For example, in all sorts of production processes that volatile material is participated in, all sorts of craft parameter are like rate of temperature, pressure, response is change, adopt measure correctly, timelily to control only, ability gets anticipated result. Normal >2. Classification control principle Normal > has the system of explosive danger to include each subsystem, subsystem. Each other of its dimensions, limits is not identical, dangerous level, characteristic also not identical. Accordingly, must reach the dangerous level of volatile material in the light of the different characteristic that produces process, take corresponding step, ability is accomplished already safe economic effect. Normal >3. Mutiple level control principle Normal > is dangerous to explosive accident, must inspect its risk level to adopt mutiple level control principle, in order to increase its dependability. Include 6 arrangement commonly, namely essential preventive those who prevent an accident to expand is control, compensatory sex control, preventive control, defend performance control, regular control and urgent sex control, detailed sees next tables.
