In any use of compliant materials (paper, dress and upholstery fabrics, etc) they may burn rapidly if accidentally ignited by a naked flame and the fumes and smoke produced, particularly from synthetic materials, may be an additional hazard.

This document is a guide to making a portable device which can be used to monitor the air, in terms of PM2.5.

These tiny particles can come from a variety of sources and could be harmful. This device will indicate when the relative number of particulates in the air is high.  It could be used to monitor the air in a workshop.
