ToolCoverage helper
Spark spray & coverage helper
Pick a hot-work process to see, in general terms, how far its sparks or molten dross tend to travel — and how far to think about protecting the floor around it. It's general guidance to help you scope coverage, not a site-specific measurement.
How to use this
Pick the process you run and the panel describes, in general terms, how far its sparks or molten dross tend to travel and how far to think about protecting the floor. The reach descriptions are indicative — real spread depends on the material, settings, height and the floor itself.
The one firm figure here is the recognised hot-work clearance: NFPA 51Bcalls for clearing or protecting combustibles within about 10.7 m (35 ft)of the work, and UK sites commonly work to a similar ~10 m zone. Treat everything else as a starting point for your own risk assessment, not a guarantee.
Once you know the process, size the quantity with thewelding bay matting calculator, or readhow far sparks travel & exclusion zones. Tell us the process and area and we'll specify a suitable mat.
