Speaking of food

Mouth watering

Can have a delicious meal

What else can I worry about?

Not on the way to delicious food

On the way to creating delicious food

Why is this much less

"Canteen in the family"

Aesthetic color matching

Refreshing dishes

"Please give me a spoonful" impulse

Because these homemade dishes

Some canteens are on fire

But some canteens are really hot

On December 13, 2021, a fire broke out in a university canteen in Guangdong. There was an open fire and thick smoke. The fire was located in the oil fume pipe of the kitchen on the second floor, with a burning area of about 1 square meter. Fortunately, firefighters quickly put out the fire, and no casualties were caused by the accident.

At 12:10 on January 7, the canteen of Fengshan sub district office in Wulong District, Chongqing collapsed, causing people to be trapped. It is suspected that the gas leakage and explosion of the canteen, of which 16 people were killed and 10 were injured.

The canteens of government agencies, schools and communities are densely populated

Large gas consumption!

In addition, the dining staff and time are relatively concentrated

In case of gas deflagration accident in such places

The consequences are very serious! Bad social impact!

Therefore, the gas consumption of the canteen is safe

Pay special attention to prevention!

Such canteens are still in use

Old electrochemical or catalytic combustion gas leakage detector

But over time

These detectors have no professional maintenance

It soon became nothing

Article 36 of the new production safety law clearly stipulates: "if the production and business operation units in catering and other industries use gas, they shall install combustible gas alarm devices and ensure their normal use."

At present, most canteens use gas

Are in a state of no safety monitoring

There are great potential safety hazards!

According to the current situation of gas safety in canteen

Hanhai optoelectronics adopts the most advanced

Laser absorption spectrum gas detection technology

Designed a complete set of solutions

It can eliminate the existing potential safety hazards in the canteen of organs and units!

Passive optical fiber laser leakage monitoring system
