Use flameproof fittings, earth all containers to remove the possibility of sparks from static electricity and avoid ignition sources.
Flammability:
Goggles and dust mask recommended during handling of bulk product when dust is generated.
Personal Protection:
Reduce drop heights and impacts during handling to reduce dust levels. Ensure ventilation is adequate to maintain concentrations of briquette dust in air below exposure standards.

UN Number:
Briquettes have been exempted from the Hazardous Goods regulations for road and rail transport and storage within Australia. For bulk shipments by sea, briquettes are classified by the Australian Maritime Safety Authority as self heating coal (liable to spontaneous heating but not emitting methane) under the International Maritime Organisation Goods Code Supplement Section Code of Safe Practice for Solid Fuel Cargoes. For bulk shipments by sea UN Classification Number 3088 applies. For all other purposes, particularly when packed in drums, bags and containers, the following applies:
Statement of Hazardous Nature
Briquettes are not classified as hazardous according to the hazardous substances classification criteria of Worksafe Australia.
It is brownish-black and has a high inherent moisture content, sometimes as high as 45 percent, and very high ash content compared to bituminous coal. The heat content of lignite ranges from 9 to
17 million Btu per short ton (10 to 20 MJ/kg) on a moist, mineral-matter-free basis. The heat content of lignite consumed in the United States averages 13 million Btu/ton (15 MJ/kg), on the
as-received basis (i.e., containing both inherent moisture and mineral matter).
Lignite, often referred to as brown coal, is the lowest rank of coal and used almost exclusively as fuel for steam-electric power generation.
