Abstract: The results of the study concentration field of chemical harmful substances in the entire volume of the room during the operation of emergency ventilation with a given air exchange are proposed. Explosion safety of production rooms is provided on condition of 10 % of the lower limit of flame spread on gas-air mixes and observance of equality of concentrations of harmful substance in the working zone and in the leaving air. Emergency ventilation is proposed, which provides uniform removal of air from the entire volume of the room to exclude the formation of stagnant zones and ensure explosion safety in chemical emissions. Emergency ventilation with a natural flow of air through the holes with variable aerodynamic characteristics with a volume-oriented arrangement of supply and exhaust holes to ensure uniformity of the flow and removal of air from the entire volume of the production room.
