Without more information it is difficult to be precise, but working with glass fibre and resins raises a number of issues. (I have just spent the day in a factory where this is going on!) The resin will certainly contain skin sensitisers, although these may not be shown on the label or safety data sheet (as was the case today). It may also contain styrene, for which the only glove providing long term protection is one from Viton (at around £70 per pair!). You will also need to consider airborne exposure, both for inhalation and skin. Almost certainly there will be acetone, for which the only glove is from butyl rubber - probably not what is suggested on the safety data sheet. I am assuming that the work will be carried out within a building, so extraction systems will be needed. If the GRP moulding is to be worked on afterwards, e.g. cut, drilled, etc., keep in mind that any sensitisers can remain active for quite some time after the moulding has set hard. If these are large, heavy mouldings, consider also the manual handling aspects. Hope this is of some help to get you started. Chris

Noise may well be a problem in post-moulding shaping and finishing. So too may be the dust/debris generated by these processes (inhalation, impact with eyes etc, fire). Hand tool vibration may ned to be considered. My experience of this type of operation is that sometimes big things are produced in small workshops leading to congestion and trailing hoses/cables. Big boats will need a lifting and transportation plan to get them from the workshop on to the water. Apologies if this is already apparent to you.
