Classification of explosive hazard areas

2016-11-10View Original

Thread Content

I would like to ask fellow sailors: There is a pilot-scale device in the laboratory that uses ethanol, which is a flammable liquid of Class A. The amount used and stored is 5 kg, and it is used in a well-ventilated area. Is it necessary to draw a map showing the areas at risk of explosion?

Refer to Clause 5.4.7 on devices in hazardous areas in \"Safety of Testing Laboratories – Part 2: Electrical Aspects\" GB/T27426.2-2014
