Audience: Administrators
What school and district leaders need to decide about a laser program: cost, funding, proposals, safety responsibilities and staffing.
-
What has to happen before a laser cutter is used again after a fire?
A review, and a written release from the person your procedure names.
-
Are laser cutters a fire hazard?
Yes. A laser cutter works by burning material away with concentrated heat, so a flare-up is always possible, even in a well-kept machine.
-
How much airflow does a laser cutter exhaust need?
There is no single number. The airflow your machine needs is in its manufacturer’s installation specification, and your facilities staff or EH&S office confirm by measurement that the room and the ductwork actually deliver it.
-
Are laser cutter fumes harmful?
They can be. Laser cutting burns material away, and MIT compares breathing the smoke to breathing smoke from burning materials: respiratory irritation and inhalation of toxic particles and gases.
-
What is a laser fume extractor, and how does it work?
A fume extractor is usually a filter unit that connects to the laser cutter, pulls the smoke out of the machine and passes it through filters.
-
Does a laser engraver need an enclosure?
For a classroom without a laser safety officer and a written laser safety program, yes.
-
What warning signs does a laser cutter room need?
It depends on the machine’s laser class, so there is no one list for every room.
-
Can a laser cutter set off a school smoke alarm?
It is possible, and you should plan as if it will happen.
-
What type of fire extinguisher should be kept near a laser cutter?
Your institution’s fire safety plan and fire authority decide that, not this page and not the instructor.
-
Why do laser cutters start fires?
A laser cutter works by concentrating heat on material that can burn, so a flare-up is always possible.
