Deadly reaction of lime sulphur with NPK solution

An incident where a farm worker was exposed to Hydrogen Sulphide due to mixing of Lime sulphur (mixture of calcium polysulfides formed by reacting calcium hydroxide with sulphur) with NPK solution is highlighted in this link.

MSDS of lime sulphur is given in this link where it mentions acidic materials or dilution with water will cause the release of hydrogen sulfide.
