COSHH.

COSHH is the UK counterpart to HazCom, and the difference is the shape of the duty: it is not a list of banned chemicals, it is an obligation to assess and control. What the regulations cover is broad on purpose: anything with a workplace exposure limit, anything classified as irritant, harmful, corrosive or worse, biological agents, and ordinary dust above the stated concentrations. The catch for a print shop is that the assessment must also cover substances your own process creates. Powder from a DTF shaker, mist off a heat press, fume from an unvented cure tunnel: none of that arrives in a labelled drum, so none of it is in the SDS binder. HSE's control order is eliminate, change the process, contain, then control, with PPE last rather than first, and a shop that reached straight for gloves and a mask has not done a COSHH assessment. It has bought PPE, and an inspector reads the difference in about a minute.
