Hey everyone 
Just wanted to share some laser engraving safety tips I’ve picked up after using the OneLaser Machines. Whether you’re a hobbyist or a full-time maker, staying safe while creating is non-negotiable.
Laser engravers are powerful tools, they can cut through wood, acrylic, and even leather with stunning precision. But with great power comes… yeah, you guessed it: responsibility!
So here’s a no-fluff breakdown of what I’ve learned to stay safe, focused, and fire-free 
1. What Are Laser Hazards?
Let’s start with the risks no one likes to talk about:
Direct or reflected laser beams can cause serious eye damage
Skin burns from the beam or hot materials
Toxic fumes from engraving plastics or leather
Fire hazards from flammable materials or scraps
OneLaser’s machines (like the X Series and Hydra) are packed with smart features like lid interlocks that stop the beam if the lid’s open. Still, never disable safety interlocks and always wear protective eyewear during maintenance.
Your eyes and lungs will thank you 
2. Built-in Safety: Lid Interlock System
One thing I love about the OneLaser machines is their “No Covered Lid = No Operation” safety rule.
If the lid’s even slightly open, the laser won’t fire.
If you open it mid-job, it immediately stops.
This feature has saved me more than once when I got distracted and forgot to close the lid all the way. 
Small detail. Big peace of mind.
3. Set Up a Safe Workspace
Your laser’s environment plays a huge role in safety.
Ventilation is key – especially if you’re cutting plastics or leather.
I use OneLaser’s FumeGuard™ system and always keep a window cracked or use extra exhaust fans.
Clear the area – No rags, wood bits, or packaging near the laser bed.
Always have a CO₂ fire extinguisher nearby
Never walk away from a running job
4. Know Your Materials
Not everything should go in a laser engraver. Some materials release toxic fumes or catch fire easily.
Never engrave:
- PVC
- Vinyl
- Mystery plastics or foams
Safe bets:
- Wood
- Acrylic
- Anodized aluminum
- Leather
- Paper
Pro tip: OneLaser machines have preset material settings to make life easier. I also love the RedDot alignment tool—saves me from trial-and-error burns.
5. Watch for Fire Risks & Heat Buildup
Lasers = heat.
Heat + wood dust = potential fire.
That’s why I never run the laser when I’m not in the room. OneLaser’s built-in temperature monitoring system shuts things down if it gets too hot but staying alert is still your #1 defense.
More fire safety tips:
- Use Air Assist (included in all OneLaser units) to blow away debris
- Clean out leftover scraps before starting the next job
- Stay close during runs
6. Use the Right Safety Gear
When doing maintenance or alignment, don’t forget the basics:
Laser-rated safety goggles (especially for CO₂ lasers)
Respirator or face mask if you’re working in a tight space
Gloves when cleaning or handling unknown materials
Even enclosed machines like the X Series still need caution during cleaning or adjusting.
7. Know Your Machine
Don’t just plug and go—know your engraver inside out.
Read the manual
Take advantage of support and onboarding
Learn how emergency stops and interlocks work
Don’t skip material setup tutorials
8. Maintenance = Safety
A clean machine is a safe machine. No exceptions.
Here’s what I do monthly (or more with heavy use):
- Wipe the bed, lens, and mirrors with alcohol & Q-tips
- Clean out debris and catch trays
- Check fume extractor and fans
- Never bypass or disable built-in safety features
Most of these take 10–15 minutes. Worth it for the peace of mind and performance boost.
