APPLICATION
Is used in the production of insomers for chemical fibres and
as a dissolvent.
SECURITY REQUIREMENTS
Cyclohexane - is highly flammable liquid. Cyclohexane vapors
and air creat explosive mixtures. The rate of explosive mixtures. The rate of
explosivily is 1,2-10,6% (according to volume). Flash point is 18°C,
selfignition point is 260°C. The tolerable concentration of cyclohexane in the
air of working zone within a production building is 80 mg/m3.
Cyclohexane is a skin irritant. Content of Cyclohexane
exceeding the tolerable concentration can affect human nervous system.

PACKING, TRANSPORTATION STORAGE
Cyclohexane is transported in railtanks with upper discharge
or equipped with multipurpose discharge device. The hatch cover of the tank
should be tightly closed and sealed. The tanks should be filled with Ciclohexane
up to not more than 95% of their capacity.
Cyclohexane is stored in reservoirs in special warehouses for
highly flammable liquids.
