Laser pointers can start fires although the ordinary laser pointers are not powerful enough to start most fires.
Still though an ordinary laser pointer could potentially start a fire on a leaf or paper in certain conditions.
For most fires to be started with a laser pointer though you would need a very powerful laser pointer to cause ignition.
Class 4 laser beams represent a fire hazard and under some situations it is possible that Class 3 lasers can initiate fires.
Use flame retardant materials wherever applicable with all laser applications.
Green and blue lasers have higher wavelengths, which help them achieve their color and strength.
This also means they require more energy to maintain a steady light stream than a red-beam laser.
What is this? When focused, the energy from green and blue lasers can be used to start fires.
The greater a laser pointer's output power, the more likely it will cause serious eye injuries, burn skin and temporarily — or permanently — impair the vision of pilots, drivers or bystanders.
That much is clear. But judging the safety of that laser pointer in your desk drawer or in your kid's hand isn't simple.
The major danger of laser light is hazards from beams entering the eye.
The eye is the organ most sensitive to light.
Just as a magnifying glass can be used to focus the sun and burn wood, the lens in the human eye focuses the laser beam into a tiny spot than can burn the retina.
Intentionally aiming lasers at aircrafts poses a safety threat to pilots and violates federal law.
Many high-powered lasers can incapacitate pilots flying aircraft that may be carrying hundreds of passengers.
Pointing a laser at a plane is a federal crime.
According to United States law, a person convicted of aiming a laser pointer at a plane faces prison time of up to five years.
Additionally, they may face fines from the FAA of up to $11,000.00 per violation, and up to $30,800.00 for multiple incidents.
