Thermoplastic materials are joined using a jet of hot air to melt and fuse the plastics material. A filler rod of the same material may be used to reinforce the joint.

The solvents are usually highly flammable (hydrocarbons, esters or ketones) but are sometimes non-flammable chlorinated hydrocarbons. This risk assessment also covers paint strippers that use similar solvents.

Controlling the dust and fumes from shaping and cutting plastic materials by hand and by machine.

This guide gives an overview of the types of things that should be considered when planning an activity that uses plastics based materials.
