Distillery Plant section
In the Distillery Plant section 188.8.131.52 categorically mentions:
Keeping away from heat, sparks and open flame, care will be taken for avoidance of spillage, skin and eye contact, well ventilation, Use of approved respirator if concentration of alcohol in air is above acceptable level will be promoted
To ensure no sparks it is very critical to use non-sparking hand tools in the Distillery Plant. In fact many sugar and distilleries maintain a non-sparking toolkit with commonly used tools for performing maintenance and operations in this area
Section 184.108.40.206 identifies Sulphur dust as a potential hazard for dust explosion. One of the conditions for dust explosion in this area has been identified as:
Presence of source of ignition
Sulphur dust has a very low ignition temperature of 190 °C. Further Sulphur burns to produce SO2 (Sulphur dioxide) gas which is extremely irritating and toxic. This create a double hazard as Sulphur dust not only has a risk of igniting and causing other accidents but the SO2 fumes can also prove fatal for personnel operating in its presence.
A mitigation measure identified by the author for the above is use of a non-sparking scoop and non-sparking shovel in this area to avoid any stray sparks
