Anything that burns, gives off smoke, carbon monoxide, flames, or fumes requires special safety precautions – lasers are no different. Although lasers sold in the industry are safe, bad things can happen.
If your building does not have a smoke detection system and a fire alarm, add a smoke detector near your laser. Also add a carbon monoxide detector near it with a series of fire extinguishers throughout your shop. Place one about 10 feet from the laser. Do not place them right next to equipment as a fire in the equipment may make it difficult to access an extinguisher if it’s too close.
