Why Can Lasers Be Dangerous?

Laser cutters use a focused beam of light to cut through various materials such as wood, plastic, and metal. The high-energy beam is so concentrated that it can vaporize the material, which also makes the laser dangerous.

Laser Cutter Hazards

1. Fires

Laser cutters can cause fires if the material being cut is flammable or combustible. If the laser’s energy is not properly controlled, the laser beam can ignite the material and any other combustible in close proximity. It is essential to use only laser cutter-safe materials on a laser bed to avoid a fire hazard.

2. Dangerous Fumes/Vapors

When laser cut, some materials can emit laser-generated air contaminants (LGACs), which are harmful gases that can pose serious health risks when inhaled. For example, PVC releases toxic gases (including chlorine) when lasered, which is highly corrosive and dangerous.

3. Eye Damage

Eye damage can occur when a laser beam enters the eye and damages the retina. The more powerful the laser, the more dangerous it is. In Class 3B and Class 4 lasers, even reflections can cause serious eye damage. Always wear laser safety glasses and ensure the laser is properly contained.

4. Skin Burns

Laser cutters can cause severe skin burns when the laser’s high-energy light comes into contact with the skin, heating it to the point of damage or combustion.

5. Cuts and Wounds

Laser cutting can create sharp or pointed edges on the material. These can potentially cause cuts or puncture wounds. Wearing cut-resistant gloves provides extra protection.
