Corporate manslaughter has become a nationwide talking point once again with the first anniversary of the Grenfell Tower fire tragedy and the start of the official inquiry.

Following the fire last year, the Metropolitan Police investigated both the Royal Borough of Kensington and Chelsea, which owned the tower, and the Kensington and Chelsea Tenancy Management Organisation, which managed it, on suspicion of corporate manslaughter. Culpability for the tragedy has yet to be established.

But from a construction perspective, when are companies culpable of corporate manslaughter? And what should they do if accused?

What is corporate manslaughter?

Corporate manslaughter is a criminal offence through which a company or corporation is found responsible for a person’s death. The offence came into law in 2008 when the Corporate Manslaughter and Corporate Homicide Act 2007 came into being. Companies can be found guilty of this offence if their serious management failures led to a gross breach of duty of care.

If found guilty, firms could face an unlimited fine of up to £20m, depending on the severity of the offence, or the court could order them to overhaul their health and safety procedures.

As part of the 2007 act there are specific ways to determine if an incident falls under the offence of corporate manslaughter.

Following a fatality, the business’s internal processes which led up to the death will be examined, including any health and safety procedures, to determine if there were systematic failures which led to negligence.

In the construction industry, the implementation of health and safety procedures is even more vital due to the hazardous working conditions and proximity to heavy machinery. As such, it is crucial that any safety measures are not just sent out to staff, but followed strictly.

For a company to be accused of corporate manslaughter, it must be proved that there was a gross breach of procedure, which left workers or the public at a significant risk. This breach must be major, and be identified as a significant departure from expected standards.

In 2015, Master Construction Products became the 26th company to be convicted of corporate manslaughter after a worker was crushed to death by a machine used to sort waste materials. It was fined £255,000 and an HSE investigation uncovered that there was no safe system of work outlined for the machinery.

A significant part of the failure must also have occurred among those with decision-making powers. Construction managers are under extreme pressure to ensure their firm follows procedure and adheres to regulations to prevent serious incidents on site.

And not only should they safeguard their workers’ wellbeing, but they are also responsible for preventing injury to the public. Monavon Construction was the first company to be sentenced under the act, and received a fine of £550,000 after pleading guilty to two counts of corporate manslaughter, when two men suffered fatal injuries after falling into a well in 2013.

Public responsibility extends to the safety of materials used in a project. This underlines the importance of obtaining up-to-date documents relating to the safety testing of any product used. As managers, it is not just vital that you ensure your workers follow procedures, but that your third-party suppliers do too.

What next if you’re facing a charge?

It is likely that an investigation will be undertaken by the Health and Safety Executive (HSE) to ascertain blame for the fatality, which could also include a criminal prosecution for health and safety offences.

Once the fatality occurs, there are likely to be investigations into health and safety procedures, police visits to the site, and interviews with HSE among many other steps.

Construction companies and managers could also receive publicity orders, requesting the business to provide details of previous convictions and fines, and a remedial act instructing them to overhaul procedures which resulted in the death.
