HSW: exemptions?

I’m in hospital, whiling away the time as the medical profession tries to sort out my low blood pressure and saturation levels as well as pumping me with fluids and antibiotics. I’m overlooking works to the roof mounted AC/ventilation system of a new Children’s Emergency Department.

Operatives are overwrapping insulation with a self adhesive vinyl protection sheet. Despite being over 5m high in places and the work being close to the edges, there is absolutely zero edge protection. Furthermore, materials are being delivered to the site and thrown up to a lower roof and subsequently to a higher level.

One operative just nicked his hand on a sharp vinyl edge, and just kept going.

So my question is – when did insulation companies become exempt from HSW Act?

Update: It seems that my report had the desired effect. The works were stopped, the Client was contacted, the contractor was interviewed, and the matter will be brought up at the Client’s next H&S meeting. Some may accuse me of H&S overzealousness, but rather that than serious injury or fatality.
