Sulphur storage, handling and safety

This section should be read in conjunction with the raw material hazard data sheet (see 3.1.3.) and the physical property data sheet (see 3.1.4.). 

Solid elemental sulphur is virtually non-toxic although sulphur dust can cause systemic poisoning if inhaled and can irritate the eyes and mucous membranes of the respiratory tract. No specific exposure limits exist for solid sulphur and therefore it should be considered as a nuisance dust with the following exposure limits  

Because of its low ignition energy and tendency to develop static charges sulphur presents a fire and explosion hazard. In the event of fire, sulphur bums with a slow blue flame, invisible to the naked eye in daylight, and evolves sulphur dioxide (see 3.2). 

In areas where exposure to hydrogen sulphide is possible, e.g. sulphur melting pits, adequate ventilation is required. 

The primary hazards of liquid sulphur are its relatively low ignition point, the possible presence of hydrogen sulphide (see solid sulphur) and the fact that it is a hot liquid capable of producing severe bums.
