1、Industrially the production of thin films of CdS, required in e.g. photoresistors and chemical bath deposition (CBD), has been investigated using the hydrolysis of thiourea as the source of sulfide anions and an ammonium salt /ammonia buffer solution to control pH.
2、Cadmium sulfide can be produced from volatile cadmium alkyls, an example is the reaction of dimethylcadmium with diethyl sulfide to produce a film of CdS using metalorganic vapour phase epitaxy techniques.

Cadmium and its compounds are on the Community Right-To-Know List. Reported in EPA TSCA Inventory.

1、Fire Fighting Measures of Cadmium sulfide (CAS NO.1306-23-6) 
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. 
Extinguishing Media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. 
2、Handling and Storage of Cadmium sulfide (CAS NO.1306-23-6)
Handling: Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood. 
Storage: Store in a cool, dry place. Store in a tightly closed container.
