Questions of improvement of a method of calculation of fire hazard of the gas mixtures based on tetrachlormethane addressing on objects of an oil and gas complex are considered. Authors installed the mechanism of formation of dangerous factors of the fire when using of the mixed combustible environment on objects of an oil and gas complex, expressions are found and approximation of fire hazard (with an accuracy evenly best of all than 1.5%) by means of elementary functions is executed.
