Maximum surface temperature of explosion-proof (Ex) equipment can be one of the sufficient causes of explosion if surface temperature is more than the ignition temperature of surrounding explosive atmosphere where Ex equipment installed. Temperature class is given for any Ex equipment/ system on the
READ MORE On and offshore drilling of gas or oil is a high risk sector with respect to fire and explosion hazards. Therefore, the European Union has implemented Directive 92/91/EEC to protect workers on oil platforms. Additionally, to ensure the safety of operations in these potentially explosive atmospheres,
