B. The Air We Breathe: Ventilation and Health


Another often-overlooked aspect of working with laser engraving machines is assessing the quality of air in your workspace. The working of laser technology is a high-powered task that may cause many chemical reactions to happen, releasing elements present in the alloy into the surrounding air.

Now, these poisonous fumes, vapors, particles, and toxic metallic extractions from the substrates can make your breathing unbearable and, in many cases, can pose some serious health issues.

ABS, PVC, and fiberglass are the three most common materials on the “Forbidden List,” so be careful when navigating these materials.

In order to combat this issue, adequate ventilation is all you need. Make sure your working area has good natural airflow or either way, install mechanical systems in place.

Installing air filtration units to capture and remove airborne contaminants is another effective way to deal with this aspect. Additionally, wearing respiratory protection, such as masks or respirators, can provide an added layer of defense against inhaling harmful particles and fumes.

C. Fire Hazards: Prevention and Preparedness

Laser marking, cutting, and heating are all thermal processes, so they can cause a flame at the surface where the laser is being applied, making the fire hazard a legitimate concern.

Certain materials used in the processes might ignite, especially when you’re processing flammable materials such as wood and plastics. So, these materials can quickly escalate into dangerous fires without careful precautions.

But don’t be scared! All our laser equipment has a very decent setup that will make you avoid fire hazards in most cases.

Still, to mitigate its harmfulness, implementing fire safety protocols, such as having fire extinguishers readily available and knowing how to use them, is crucial for prompt response in the event of a fire emergency.

III.   A Seller’s Guide to Safe Engraving Practices

A. Selecting Safety Gear: Beyond the Basics

When it comes to protecting yourself from laser beam radiations, don’t just settle for any safety gear, but rather invest in a high-quality one that can truly keep you safe. Find eyewear that’s specially designed for laser work and that can better shield your eyes from the wavelengths these laser engraving machines emit.

Additionally, you can go for a face shield for that added layer of protection, especially when you’re working around materials like brass that produce flying debris.

As for your skin, it’s sensible to reach for flame-resistant clothing made from durable materials like leather or cotton.

Also, Gloves can act like your good friend in protecting your hands from potential cuts and burns. Be mindful that it snugly fits in, simultaneously allowing for dexterity in carrying out the laser tasks with ease.

B. Understanding Your Laser Engraver’s Safety Features

When shopping for laser engraving machines, it’s wise to keep your eye on the built-in safety features such as emergency stop buttons, interlock systems, and protective enclosures.

The emergency stop button is a rapid response mechanism that prevents severity by cutting off the power source to the machine system or other components.

Interlock systems offer a safe operating practice that prevents the machine from working unless the enclosures are securely closed, thus minimizing the risk of accidental exposures.

Protective enclosures provide a physical barrier between the machine processes and the operator, thus creating a shield from direct radiation and the dispersion of fumes, smoke, or debris generated during the engraving.

ComMarker is proud to offer all these features in its laser systems so that there is no risk of accidents and injuries when shutting down the machine or preventing operation if certain safety criteria aren’t met.

Moreover, check whether or not your suppliers meet all the safety standards and compliance regulations set by the Occupational Safety and Health Administration (OSHA).
