Natural
gas
is
not
dangerous
for
human
health.
It
has
no
toxic
or
poisonous
effects.
In
high
concentrations
it
may
cause
suffocation
because
it
reduces
the
amount
of
oxygen
in
inhaled
air.
When
natural
gas
is
accumulated
in
a
closed
room
or
in
an
open
space
under
windless
conditions
an
explosive
mixture
may
be
formed
(within
the
range
of
4.4
÷
17
vol.
%)
and
an
explosion
may
occur
after
initiation
(by
open
flame,
spark,
electric
discharge).
In
rapid
expansion
from
the
higher
pressure
above
approx.
15
bar
cooling
occurs
and
water
vapour
in
the
vicinity
of
the
discharge
opening
may
freeze
–
frostbite
hazard.
Condensate
is
flammable
and
saturated
with
methane
at
the
moment
of
discharge.
The
recommended
extinguishing
agent
is
a
dry
‐
powder
extinguisher.
