Southwark Crown Court heard that on 10 November 2017 three roofers had been working on Bromley High Street in London finishing off a large roof refurbishment project.

The trio were instructed to dismantle a decommissioned air conditioning plant and remove it from the roof in high winds.

As part of the plant was being lowered, it became detached from the rope and hook.  It fell and struck one of the workers on the pavement below, fracturing his left femur.

An HSE investigation found that only a basic manual gin wheel was provided to lower the parts, no one was assigned to supervise and none of the workers had any formal training on carrying out lifting operations or slinging loads.

There were also other failings at the site relating to working at height, control of asbestos, emergency arrangements, manual handling and a total lack of any welfare facilities for the workers.

NMC Surfacing Limited (NMC) had subcontracted the roof refurbishment work to a smaller local business, Fraden Contracts Limited.

The client was unaware NMC had subcontracted the construction work. The court heard NMC provided them with modified versions of Fraden’s risk assessment records with all references to Fraden erased.

NMC Surfacing Limited of Reading was found guilty of breaching CDM regulations and was fined £350,000 and ordered to pay £45,122.36 in costs.

Fraden Contracts Limited of Barnet had already pleaded guilty to a breach of CDM regulations and the company was fined £14,000 and ordered to pay £6,015.26 in costs.

HSE inspector, Andrew Verrall-Withers, commented after the hearing: “Little thought was giving to planning the lifting operation by the companies and it was the workers who identified passing members of the public were at risk and borrowed some barriers to try and protect them.

“It is vital construction companies do not assume that because workers have been in an industry for years, that they automatically know everything about how to safely use equipment.

“A worker suffered an injury which means he can no longer work as a roofer despite three decades of previous experience. He, or a passing member of the public, could have been killed.”
