destruction
(ODP) = 0.
Safety classification: A3. Non-
toxic but extremely flammable.
The substance is regulated by the
Montreal Protocol (1992 revision).
HAZARD IDENTIFICATION
R290
Do not smoke or inhale.
highly flammable
The gas is
Keep it away from heat sources,
hot surfaces, sparks, naked flames
or other ignition sources.
Low conc e ntrations can cause narcotic effects with possible loss of consciousness, dizziness,
headaches, nausea and loss of coordination.
High concentrations can cause asphyxiation due to reduced oxygen content in the atmosphere.
Very high conc e ntrations can cause abnormalities of the heart rhythm and sudden death.
The sprayed or splashed product may cause skin burns and serious eye damage . It is unlikely to be
dangerous by skin absorption. Repeated or prolonged contact can cause the removal of skin fat, resulting
in dryness, chapping and dermatitis.
Do not smoke or inhale.
