Evacuation indicator sign lights and fire emergency lights, smoke detectors are fire protection facilities that we often contact in life.

On the occasion of March 15, Ningbo Fire rescue Detachment did two groups of comparative experiments on fire equipment to test the quality and function of these fire products.

● Experimental process:

There are volunteers who can't get out without their lights.

As the experiment began, all power was cut off and the "fire site" was dark and full of smoke.The first group of three volunteers went to look for an escape hatch.

Reporters from the monitoring screen to see, three volunteers in the dark environment difficult to identify the direction.

The fastest escape took four minutes and 36 seconds, the second took five minutes and 42 seconds, and the third, unable to find the exit, had to be led away in eight minutes and 55 seconds.

"I didn't think it would be so difficult to escape from a fire. I couldn't see anything in it. I could only feel it with my hands."

"I've been around the same place three times," one volunteer sighed to a reporter. "Now I'm even more scared. I just wish there was a light, even a glimmer.If it's a real fire, I'm dead."

The three volunteers in the second group, though in the same "fire environment" as the first group, escaped much more smoothly under the guidance of emergency lights and evacuation sign lights.

The fastest volunteer managed to "escape" in just one minute and 36 seconds.

"I just looked at the signs, followed the directions, and sure enough, I found the exit."Said one volunteer.

How to buy qualified emergency lamps"This set of comparative experiments fully illustrates the importance of emergency lights and evacuation indicator lights."Cheng Gaoping, chief of fire control technology section of Ningbo Fire rescue Detachment, said.So how do you pick?

Cheng Gaoping suggested: one is to see whether there is an "ID card" -- formal products should have a mandatory certification certificate or technical certification report, on the product posted with an ID card, and can be found in China's fire products information network;Second, check whether the appearance, material and performance parameters of the product are consistent with the inspection report;3 it is to make a simple test bian authenticity - qualified fire emergency lighting and evacuation indicating lights should be able to enter a state of emergency, immediately after the power light-emitting time should not less than 90 minutes, it's best to choose and buy when consumer is buying a back and do the discharge test, if the emergency time is less than 90 minutes for the unqualified products.
