Dos and Don’t When Gas leak Detects
Do's:
 If the gas leakage is severe, it is very dangerous for anybody to enter the premises. Call Fire
brigade / Gas dealer.
 If there is a minor / moderate gas leakage- Turn off the knob, regulator, to stop gas supply.
 Open all doors & windows.
Don'ts:
 Do not panic.
 Do not OFF / ON any electrical switch.
 Do not light any kind of fire or lamp.
Following conditions must be avoided
1. Water Condensation
Indoor conditions, slight water condensation will influence sensors’ performance lightly.
However, if water condensation on sensors surface and keep a certain period, sensors’ sensitive will
be decreased.
2. Used in high gas concentration
No matter the sensor is electrified or not, if it is placed in high gas concentration for long time,
sensors characteristic will be affected. If lighter gas sprays the sensor, it will cause extremely
damage.
3. Long time storage
The sensors resistance will drift reversibly if it’s stored for long time without electrify, this drift is
related with storage conditions. Sensors should be stored in airproof bag without volatile silicon
compound. For the sensors with long time storage but no electrify, they need long galvanical aging
time for stability before using. The suggested aging time as follow:
Storage Time
Suggested aging time
Less than one month No less than 7 days
4. Long time exposed to adverse environment
No matter the sensors electrified or not, if exposed to adverse environment for long time, such as
high humidity, high temperature, or high pollution etc., it will influence the sensors’ performance
badly.
5. Vibration
Continual vibration will result in sensors down-lead response then break. In transportation or
assembling line, pneumatic screwdriver/ultrasonic welding machine can lead this vibration
