Shipment nd Stora.ge, Sulfur monochloride is minimally corrosive to carbon steel and iron when dry. If it is necessary to avoid discoloration caused by iron sulfide formation or chloride stress cracking, 310 stainless steel should be used. Sulfur monochloride is shipped in tank cars, tank tmcks, and steel dmms. When wet, it behaves like hydrochloric acid and attacks steel, cast iron, aluminum, stainless steels, copper and copper alloys, and many nickel-based materials. Alloys of 62 Ni—28 Mo and 54 Ni—15 Cr—16 Mo are useful under these conditions. Under DOT HM-181 sulfur monochloride is classified as a Poison Inhalation Hazard (PIH) Zone B, as well as a Corrosive Material (DOT Hazard Class B). Shipment information is available (140). 

Colorless to yellow, fuming liquid with an irritating, pungent, acrid odor like hydrochloric acid. This material is hazardous through inhalation and ingestion, and produces local skin/eye impacts. 

The hydrochloric acid salt of 3,3 -dichlorobenzidine readily photolyses in water exposed to natural sunlight, but may not readily biodegrade in soil and aeelimated sludges. It has a strong tendency to partition to soils and sediments, a property which reduces the potential for human exposure (Boyd et al. 1984 Chung and Boyd 1987 Sikka et al. 1978). Once partitioned to soil, the compound apparently binds further with humie substances to form humie-like materials that presumably would be non-hazardous (Sikka et al. 1978). However, in a recent paper, Nyman et al. (1997) stated that dehalogenation of 3,3 -dichlorobenzidine to form benzidine (also a toxie substance) occurs in sediment/water mixtures under anaerobic conditions.
