If you’re someone who frequently uses a laser cutter or is considering getting one, it’s important to understand the potential dangers that come with this powerful cutter. Laser cutters have revolutionized various industries, offering precision and efficiency like we have never seen before.

However, it’s crucial to prioritize safety when working with these machines to prevent accidents and injuries. In this article, we at IVYCNC will explore the possible dangers of using a laser cutter and discuss essential safety measures that you should follow.

What Dangers Come with Using a Laser Cutter?

Laser cutters have revolutionized various industries, offering precise and efficient cutting capabilities. However, it’s important to understand the potential dangers associated with using these powerful machines. First, let’s explore the risks involved and how to mitigate them effectively.

Exposure to Beams

Improper use of laser cutters can lead to skin and eye damage due to exposure to laser beams. However, by ensuring the laser beam is fully enclosed, the risk can be minimized. The infrared beam emitted by laser cutters are primarily is heat, and the transparent acrylic or polycarbonate window absorbs any reflected beam.

It is crucial to avoid staring directly at the cutting site for long periods, as certain materials may reflect part of the beam as visible light. To ensure safety, always keep machine doors closed and wear appropriate safety glasses, especially during beam alignment.

It’s worth noting that laser heads can unexpectedly jump during operations, potentially directing the beam toward the operator.

Electrical Risks

While laser cutters generally pose the same electrical risks as any other electrical device, there are specific considerations for lasers that use DC (glass) laser tubes. These tubes operate with one end containing extremely high voltage, around 20,000 Volts.

Mishandling such voltage can be fatal. It is crucial to handle these laser tubes with utmost care and follow proper safety protocols.

Fire Hazards

Laser cutters operate by evaporating materials using intense heat, making fire safety a significant concern. It’s important to note that the laser itself is not the primary risk but rather the materials being cut. Certain materials, such as acrylic, are more prone to catching fire and can quickly escalate from a small flame to a full-blown fire.

Fume extraction fans, responsible for removing smoke and fumes, draw in fresh air from the surroundings, exacerbating the fire risk. Therefore, immediate action is essential in extinguishing any small flame to prevent further complications.

Fumes and Smoke

Different materials, when burned, release varying amounts of smoke and fumes that need to be properly expelled. Aside from obstructing the laser beam’s path and reducing its effectiveness, these smoke and fumes can also be harmful to the equipment and pose a risk of poisoning. 

Implementing proper ventilation and utilizing appropriate fume extraction systems are crucial for maintaining a safe working environment.

Essential Laser Cutting Safety Measures

Safety always comes first if you are a laser cutter user. We have mentioned the various risks and dangers that may come with laser cutters. Now, let’s talk about the essential laser-cutting safety measures every laser cutter operator should follow:

Do not Leave the Laser Cutter Unattended

One common mistake made by new operators is leaving the laser cutter unattended during operation. Even though laser cutters can work quickly, complex projects may take hours to complete. Leaving the machine unattended poses a clear fire hazard.

Always ensure there’s a backup operator available if you need to take a break. Fire extinguishers should always be readily accessible in all workplaces.

Get Proper Training

Proper training is crucial when using a laser cutter. It is essential to understand the hazards associated with laser cutters, as they involve potentially harmful components. The manufacturer of the device often provides training.

In addition to learning about the specific protocols and safety features of your equipment, the training should address the broader risks associated with laser cutting. New operators should also undergo periodic refresher courses and training.

Read the Instruction Manual

Before starting any job with a laser cutter, it is essential to familiarize yourself with the machine. Carefully read the instructions provided in the laser cutting equipment’s manual. There is a wealth of information available on the internet.

However, the user manual is the most comprehensive source of installation, safety, and operating instructions. Each equipment model and brand is constructed differently, so relying solely on past experience may not be sufficient.

Know Your Materials

When using a laser cutter, it’s important to understand the properties of the materials you’re cutting. Some materials can produce hazardous fumes when cut with a laser, such as PVC plastic.

Always refer to the Material Safety Data Sheet (MSDS) for any safety warnings related to the material you’re using.

Protect Your Eyes

Exposure to laser beams can cause irreversible damage to the eyes. These lasers can penetrate someone’s eyes through their pupils. The extent of damage depends on various factors, including the focus of the laser beam, the area it hits, and the amount of energy it uses.

The simplest way to prevent eye damage is to use appropriate-grade protective eyewear. Additionally, using tools correctly and maintaining a safe distance can further reduce the risk of harm.

Maintain a User History

Keeping a log of who used the equipment, how they used it, what materials they processed, and how long they used it for. 

This information can provide valuable insights into the general state of the machine and prevent repeated mistakes.

Stay Alert

Accidents can happen when people become too comfortable with their routines. It is important to prioritize safety when working with lasers or any other equipment. Understand your workplace and the routines you follow while working.

Always prioritize safety before starting any task, follow best practices consistently, and remain attentive to potential hazards to your safety.

Stay Informed

It is the operator’s responsibility to thoroughly understand how to operate a laser cutter safely. Read the user manual carefully before using any equipment and ensure you comprehend all safety precautions and concerns.

Additionally, workshops should prominently display safety warnings and designate the locations of safety supplies like fire extinguishers and eye washing stations.

Always keep your workplace clean

Laser cutting safety goes hand in hand with cleanliness. While laser cutters do not emit dust, residual scrap left in the catch-bin can increase the risk of a fire. Airborne particles of chopped materials, like sawdust, have the potential to catch fire. 

Maintaining a neat and organized workspace significantly reduces the likelihood of accidents or other laser-cutting safety issues.

Conclusie

Laser cutting is a powerful and versatile method for creating precise cuts in various materials. However, it’s important to prioritize safety while operating a laser cutter machine.

By implementing the safety measures we have discussed above, you can perform a safe and successful laser-cutting job. Remember, safety should always be your first consideration when working with lasers.
