1. Preventing gas explosions in an enclosure

1.1 Control of gas phase composition outside the flammable range

The first step in preventing gas explosions in industry is to avoid designing processes with flammable premixed gas phases. In other words, when designing processes, it is necessary to assess the composition of gas phases and their flammability, and then provide the means to eliminate the presence of flammable gas phases at this stage.

The methods for calculating the flammability limits of fuel gases in an atmosphere of oxidizing gases, set out in article [
