Lasers will make you blind
In an instant. In the blink of an eye, quite literally.
Never look into the beam or at any surface the beam might reflect off of.
Never have the machine powered while the door is open.
You are responsible for your own safety.
Eyes cannot be replaced.
Work on lasers should be done by informed and well trained professionals, in safe environments. There are no second chances here, if you are not trained, get help from a professional.
Use laser safety eyewear marked for your laser’s wavelength and with optical density appropriate to its output. Have a qualified laser safety professional help select and inspect it. Never test eyewear by firing a laser at it. See OSHA’s laser eye protection guidance.
Eye protection alone isn’t enough, laser safety is an ensemble of procedures, knowledge and attention that must be paid. Improvisation has no place here.
Always make sure fire extinguishers of the adequate type are present on site.
Follow the machine manufacturer’s fire-response instructions and keep suitable firefighting equipment accessible. Do not delay an appropriate emergency response to avoid using an extinguisher or damaging the machine. See LightBurn’s fire-safety guidance.
Door Safety Switch
If the machine does not come with a switch on the door that turns the laser off when the door is open, this is stupid and dangerous.
Please install that switch, and make sure it operates properly on a regular basis.
Fire Hazard
If you leave your machine alone even for a few minutes, fire can start.
They can burn your house, and they can burn your eyes. Be careful and never leave your laser unattended.
