(2) Choosing a reasonable installation location according to the specifications and keeping a necessary safe distance are important measures for fire prevention and explosion prevention.
(3) Strengthen maintenance and overhaul to keep the electrical equipment running normally, including keeping the parameters such as voltage, current and temperature rise of the electrical equipment within allowable values, keeping sufficient insulation capacity of the electrical equipment and keeping good electrical connection.
(4) Ventilation: In explosive dangerous places, if there is a good ventilation device, the concentration of explosive mixture can be reduced.
(5) The use of fire prevention facilities plays an important role in site fire prevention. For example, in order to improve the fire resistance, the inner surface of the wooden switch box is lined with iron sheets.
(6) Grounding: The requirements for grounding (or zero connection) in explosive dangerous places are higher than those in general places. Must be grounded according to regulations.
Measures are usually methods to solve problems, which can be divided into extraordinary measures, emergency measures, preventive measures, compulsory measures and safety measures.
