Introduction
Most of household accidents due to gas happen because of inappropriate behav-
iors. 98% of gas accidents, leaks and explosions happen because of the age of the
facilities, the lack of maintenance of the devices and people’s reckless or clumsy
behaviors.
Explosions due to gas can also come from gas cylinders, bottles of soda, aerosol
products, high-pressure cleaners… The consequences of these types of explosion
are severe and can cause long-term sequelae or death.
The gas detector DDG14
This wall-mounting detector is recommended to monitor the concentration of
combustible gases (natural gas, gas-propane, butane gas). When the concentra-
tion reaches a risk level, i.e concentration above 10%, the detector activates a visual
and sound signal. This level is defined by the LEL (Lower Explosive Limit). When it
reaches 100%, the air becomes a combustible gas. Here, the alarm activates as a
precautionary measure.
Installation
Place the detector in an area where a gas leakage can occur
Place the detector between 2 to 4 meters from the gas-powered devices
Place the detector to a minimum distance of 30 cm from the corners, doors and
windows
For butane and propane gas, place the detector 30 cm above ground; for natural
gas, 30 cm below ground.
Avoid the installation of the detector:
Near windows and doors
In locations which may be subjected to airflows or draughts
In the corners of the room because of the low circulation of air
