A family name, wattage or marketplace title is not enough to compare laser equipment. Start with the exact model, module and configuration.
1. Record the exact configuration
Write down:
- manufacturer and exact model number;
- laser module and stated wavelength;
- enclosure included with that configuration;
- doors, lids and interlocks described in current documentation;
- stated product classification for the exact configuration;
- extraction, cooling and supervision instructions;
- materials the manufacturer explicitly supports or excludes.
Do not copy a classification from another power module, an optional enclosure or a product-family page.
2. Use the UKHSA boundary
The UKHSA laser radiation guidance explains that classification indicates potential risk and that actual risk also depends on use, exposure and environment. It states that Class 1 can include a higher-power laser that is fully enclosed so potentially hazardous radiation is not accessible during use.
The same guidance says Class 3B and Class 4 laser products are not suitable for general consumer use. UK Shortlists therefore does not include an exposed Class 3B or Class 4 configuration in a general consumer comparison.
UKHSA also warns that visual inspection cannot tell a non-specialist the output power. Treat a vague or inconsistent listing as unresolved rather than proof.
3. Match the material to current instructions
For every intended material, record:
- exact material identity and composition;
- whether the manufacturer lists it for the exact configuration;
- required preparation and holding method;
- extraction and ventilation instructions;
- residue, cleaning and waste instructions;
- any material the manufacturer excludes.
Do not infer that two visually similar plastics, coatings, leathers or composites behave the same under a laser.
4. Measure the complete installation
Include:
- machine with doors and lids open;
- loading and unloading clearance;
- extraction duct path and outlet arrangement;
- cooling equipment where required;
- material and finished-work storage;
- maintenance access and cleaning area.
If the exact classification, enclosure, material instructions or extraction arrangement cannot be established, use a competent fabrication service instead of progressing to a product comparison.
What this checklist does not decide
It does not certify a machine, room, material, extraction system or activity. Workplace and commercial use may require a separate assessment, controls and competent advice. Always follow current manufacturer instructions and applicable official guidance.
