Vapor dispersion enhancements water sprays

Water spray systems have been demonstrated to assist in the dispersion of vapor releases. The sprays assist in the dilution of the vapors with the induced air currents created by the velocity of the projected water particles. They cannot guarantee that a gas will reach an ignition source but do improve that probabilities that dispersion mechanisms will be enhanced. 

Some toxic chemicals have a strong affinity for water or other liquids. Sprays in the path of the cloud will absorb some of the chemical and will induce more turbulence in the cloud which can lead to enhanced dispersion. Water is used for vapors that have an affinity for water, for example halogen acids, and ammonia.
