In the need, setting of vibration sensing breaker
For the latest earthquake damage assumption (H24.10) of Yokohama-shi, the death tolls by fire largely increase from 1,548 personality, last damage assumption (H17.3).
And we are considered that (excluded for cause ignorance) is related to electricity 60% of cause of fire in past great earthquake disaster or more.
When strong earthquake was generated in Motoichi, fire from electric heat appliances, fire from electric cords snapped at electric restoration again are expected.
With vibration sensing breaker
It is effective to intercept breaker at the time of refuge, but may not get such an action at the time of major earthquake occurrence at once to prevent electric fire.
Vibration sensing breaker interrupts electric supply at the time of earthquake occurrence of seismic intensity which is higher than set point automatically and prevents fire by installing in each home and can greatly reduce damage by preventing spread of fire to other houses
About kind of vibration sensing breaker
All electricity is cut off with thing with function to sense constant seismic intensity, and to interrupt electricity basically by switchboard of home. At homes with medical appliances using electricity, attention is necessary about setting.
When we are connected to switch of switchboard of home, and sensed shaking, we drop switch by fall of weight ball or action of spring and cut off electricity of all in house. A lot of relatively cheap things do not need construction.
Instructions on installing
Because influence on medical equipment is thought about about thing interrupting all in-home electricity at the time of earthquake occurrence like switchboard types, attention is necessary in setting. In addition, it will prepare for non-ever-burning light to disturb quick and safe refuge to the outdoors because light disappears when earthquake is generated in the night because it is thought.
Please choose thing suitable for environment to live in the purchase, setting. Please consult with electric construction shops about thing needing construction such as switchboard types.
