With the popularization and popularity of laser engraver, more and more people begin to use laser engraving machines. Although laser engraving machines are very powerful, lasers also have many hazards. HTPOW has summarized a few points, hoping to give love to laser Makers and workers of engraving machines bring some good opinions. Let's discuss laser safety protection knowledge together.

There are six categories of inherent hazards in laser processing equipment.

(1) Mechanical Hazards:

Mechanical hazards include the hazards generated during the movement of laser processing equipment, manipulators or robot moving parts, mainly including the following aspects.

① The sharp edges, corners, and edges of the equipment and its moving parts are in danger of being stabbed or cut.

② The equipment and its moving parts are in danger of overturning, slipping, colliding, falling or throwing.

For example, a robot on a laser processing machine could punch holes in the shield, which could damage the laser or the laser delivery system, and could direct the laser beam at the operator, perimeter fencing, and viewing windows.

(2) Electric Shock Hazard:

Generally speaking, laser processing equipment is a high-voltage and high-current equipment. Electrical hazards may firstly be the injury of operators and equipment damage caused by high voltage and high current, and secondly, the ozone or X-rays generated by unshielded components under extremely high voltage will directly cause personal injury and death accidents such as electric shock.

(3) Noise Hazard:

The common noise sources when using laser processing equipment include the operation noise of smoking and dust removal equipment, vacuum pump motor noise, cooling water pump motor noise, cooling fan rotation noise, etc.

Without proper protection, when the total noise intensity exceeds 90 decibels, it can cause headaches, tinnitus, arrhythmia, elevated blood pressure, and even noise-induced deafness.

The sound pressure level of laser processing equipment shall not exceed 75dB(A).

(4) Fire Hazard:

The use of laser processing equipment may cause thermal hazards such as fire, explosion, and burns, which are divided into two categories: personnel burn hazards and on-site fire hazards.

The explosion sources of laser processing equipment mainly include high-power glass tube lasers, electrolytic capacitors, etc.

Thermal hazards can burn through the cooling system and working gas lines of laser processing equipment, as well as the leads of sensors, potentially causing component damage or mechanical hazards.

What's more, accidental exposure of the laser beam to flammable substances can cause a fire.

(5) Radiation Hazards:

Hazards from direct or reflected laser beams and ionizing radiation.

(6) Hazards from Laser Processing Materials:

A laser is a device that uses energy to cut materials, some of which react chemically at high temperatures. Example: While PVC can actually be cut with a laser, the heat treatment produces hydrochloric acid and toxic fumes. Therefore, we recommend that you do not laser cut PVC to prevent corrosion of the laser system and to ensure the safety of the machine operator.

How Does the Ortur Series Laser Cutting Machine Solve These Problems?

1. In order to avoid the danger of sharp corner cutting, the Ortur series laser cutting machine wraps the sharp corner with a protective cover. It can effectively prevent the occurrence of danger, especially for children. And Ortur Laser Master 3 has upgraded protection, which makes people feel more at ease when using it.

2. There are parts in mechanical equipment that may cause harm and danger to the human body, so we have adopted a "double insurance" control circuit in the design of the electrical control system:

1) Emergency stop

Shut off the machine immediately in the event of an accident.

2) 5x flip protection

If you open the front cover, the laser will stop working.

3) circuit breaker

This is a protective conductor used to protect against electric shock and/or fire.

4) Ground wire

Grounding is used to protect you from electric shock.

3. The equipment is fully enclosed, and the operating noise is not large. The main source of noise comes from external equipment, so we have equipped low-noise air assist and exhaust fans.

4. They have a flame detector which is now standard on all thunder co2 machines. But we hear it all the time, don't run a laser unless you're monitoring it.

Security Advice

Users need to receive appropriate training on potential hazards, control measures, laboratory and manufacturer operating procedures. Additionally, it is important to use personal protective equipment (PPE), emergency procedures, and safety precautions for operating a router. Required PPE includes safety glasses to protect eyes from radiation, particles, debris, etc., appropriate skin protection to reduce burns, and hearing protection (if necessary).

The glass laser safety viewing window fitted in the Ortur Laser Master 3 combined with the safety interlock does provide adequate protection and complies with published safety standards

You want to look for a CE certified solution with a wavelength range of 1060nm – 1085nm and an optical density of at least 4+.


Always have a properly maintained and inspected fire extinguisher on hand. HTPOW recommends using a carbon dioxide fire extinguisher or a Halotron fire extinguisher.

You "could" use a standard multipurpose dry chemical fire extinguisher, but they leave an abrasive, corrosive residue that's hard to clean up, and it can damage electronics and mechanics, bearings, fans, etc...

CO2 fire extinguishers leave no residue. The Halotron Extinguisher releases a clean, easily removable substance that is not harmful to the mechanics or wirin
