Most of the monomers used in the manufacture of PMR polyimides are, to varying degrees, toxic products (cf. occupational medicine safety data sheets for each species presented in table 1 ). They must be handled in a ventilated room or workshop, whether in solution or prepreg form.

When MDAs are used, handling is carried out in a clean room, with recovery of volatile products, and operators must be fully protected by waterproof overalls and helmets. In addition, systematic medical check-ups every year, or even every 6 months for the most exposed, are strongly recommended (blood count or complete blood analysis). Excess and residual solvents and prepregs must be recovered in sealed packaging for subsequent destruction....
