Ethyl acetate (C4H8O2)
has a fruity smell and is very volatile.
The substance is sparingly soluble in water.
The vapors are irritating to eyes and the
Inhalation or ingestion of large amounts can
cause headache, nausea, dizziness and in severe cases,
The liquid degreases the skin.
Contact with eyes causes irritation.
Ethyl acetate is highly flammable.
Basics on gas monotoring
Gas monitoring of combustible gases serve to obtain alarm in case of
Ethyl acetate is a heavy explosive gas
with a flammable range from 2.1 to 11.5 vol%.
The density of the gas is 3.04. (Air = 1,0)
The detector should be mounted appr.
0.2 m above the floor.
Appropriate alarm levels
can be determined from case to case, but outdoors, we recommend
level 1 to 10% of LEL and level 2 to 20% of LEL.
on LEL och explosion hazard
Alarm level 1 should result in control measures while alarm level 2 should be regarded as an emergency alarm.
When forwarding alarms to local emergency services, we recommend
using two detectors at alarm level 2 in order to avoid false alarms.
Alarm level 2 should result in flashlight and/or audible alarm at the
Flashlight should be used for alarm level 1.
Outdoor Gas Monitoring
Since recommendations on monitoring always depend on the
circumstances in the various specific cases, one must always
evaluate the effects of gas monitoring.
detector placement consider the following:
All pieces of equipment connected to the
object that are considered to be potential leak sources inside
buildings/sheds should be monitored.
Sometimes special consideration must be
taken to local residents or other factors where the slightest
prescence of gas is undesirable.
Plants have sometimes been built so that not
even strong winds could have prevented a certain accumulation of
flammable gas around the alarm object.
The advantage of creating a special alarm area is that alarms
from the gas monitoring unit can be obtained at a very early stage.
The disadvantage of creating a special
alarm area is that explosive gas concentrations can build up in here.
With no special alarm area, explosive gas concentrations might not
Choice of Equipment
The Stand-alone detector Combi is a detector
where power supply, alarm and control functions are integrated in
the detector housing. This detector is used where very simple
systems are sought and only few monitoring points are desired
