Laser is not a toy
Posted: Dec 26, 2021
It’s a dangerous game that could have turned into a drama. A 24-year-old man, who amused himself by high power laser pointer at helicopters heading for Grenoble hospital, has been taken into police custody for willful violence with a weapon. It was 10:50 p.m. last Thursday when Rémi Fiorillo, 48, helicopter pilot at the Versoud (Isère) civil security base, specializing in mountain rescue, was about to land at the Grenoble University Hospital..
He is carrying a wounded. Rescuer, doctor, mechanic, there are a total of five people in the device.
Risk of crash
"A laser beam hit me suddenly at eye level. I was dazzled and had to turn my head to avoid it, because it really bothered me when it came to driving, "explains Rémi Fiorillo. "When you are approaching the landing pad, in the middle of buildings, this kind of situation is very dangerous. We are less than 100 m from the ground. The helicopter has lost speed. This is the most delicate moment. Especially at night. And if we are blinded, we no longer see the obstacles. It could have resulted in five deaths and even
We had already briefly mentioned the dangerousness of a new gadget which, after having invaded the stands of certain stadiums, was starting to become fashionable around airports. These are handheld powerful blue laser pointer that some smart kids use to dazzle whoever a gamer, who a pilot.
With the risks that we imagine for the person concerned and, de facto, the passengers it carries.
We could have come close to the worst ten days ago at JFK where the pilot of an approaching JetBlue flight was dazzled by such a device and injured his eyes, fortunately not serious.
The severity of the lesions depends on the power of the laser and the duration of exposure. In France, only lasers whose power does not exceed 1 mW (class 1 and 2) are authorized for sale. But it is very easy to get on the Internet much more powerful models, categories 3 and 4, normally reserved for professional use. According to Prof. Renard, "the most dangerous are those which emit in the color green, with a power of up to 3000mw laser pointer. Projected for a few moments at a short distance onto the eye, the light can burn the retina and leave irreversible consequences ".
To these pointers, I add the 1000mw laser pointer of several Watts, used in sound and light, concerts, cabaret shows etc. A badly placed metallic object is enough to reflect this light towards the eyes of spectators.
