Their comments came after Italy’s umpteenth workplace accident tragedy, as they went on to explain that waste suction was supposed to have been handled from above
The contract stipulated with Amap, the municipal company that had given their company, the Quadrifoglio group, the job, reportedly stipulated that the suction of sewage was to be done from the surface by means of a pumping truck.
It also stipulated that the personnel were not to go underground, officials said.
This explains why none of the victims wore masks or had gas alerts, a device that measures the concentration of hydrogen sulphide, the gas that eventually killed them.
A sixth worker was said to be in extremely serious condition in hospital, fighting for his life.
The five victims were hit by the sulphur dioxide after a rupture in a sewage cap, sources explained Tuesday.
The latest in a spate of Italian workplace accidents cost the lives of four Quadrifoglio Group workers and a temporary worker from Amap.
Quadrifoglio had been subcontracted by Tek, which had been awarded the contract by Amap, to carry out maintenance work on the sewage network.
