Six hours to save worker's arm severed in machinery incident

A clinical waste disposal company has been fined £300,000 after one of its workers severed his arm from the elbow down while unblocking machinery.

The man - who was 42 at the time of the incident in February 2022 - had been working his usual night shift at Tradebe Healthcare National’s site on Elgin Industrial Estate in Swindon. He was with a colleague when he attempted to clear an obstruction on an autoclave machine. His left arm became trapped and was crushed by the door - severing it from the elbow down.

He was rushed to hospital where doctors spent six hours saving his arm. He has since had three major surgeries to restore the use of his hand, though he now suffers from very limited movement.

Part of his treatment has involved skin grafts taken from the thigh of his left leg as well as veins from his left and right legs transplanted into the arm. He still suffers from constant pain and struggles to complete many everyday tasks independently.

Autoclave machines are pressure vessels with lids or doors and are used in a variety of processes whereby products are placed inside and subjected to greater than atmospheric pressure and elevated temperatures. A rotoclave is a type of autoclave that rotates during operation. On this particular site, it was used for high temperature sterilisation of waste.

HSE's investigation found multiple failings by the company including exposing workers to risk… The machine was surrounded by an enclosure which included an access gate at its rear. The man had used this unsecured rear gate to walk into the enclosure to reach in to remove the debris. His colleague was unable to see him and due to miscommunication, mistakenly resumed operation of the machine.

An investigation by the Health & Safety Executive revealed multiple failings by the company, including:

• Not having sufficient measures in place to prevent employees from being at risk when clearing blockages.
• Employees being exposed to risk, specifically in relation to the failure to properly isolate the machine before cleaning.
• Employees not being provided with sufficient information and instruction about how to use and how to clean the machine safely.

The investigation also found that training provided to employees was inadequate and that employees were not suitably supervised.

Tradebe Healthcare National of Atlas House Third Avenue, Globe Park, Marlow, Buckinghamshire, pleaded guilty to breaching Section 2(1) of the Health & Safety at Work etc. Act 1974. The company was fined £300,000 and ordered to pay costs of £18,710.

"This was a harrowing incident made more tragic by the fact that events of this kind are all-too foreseeable,” says HSE inspector Emma Preston. "Accidents which happen when cleaning and maintaining machinery often result in life-changing injuries, which is why companies need to make sure they have robust lock-off procedures, effective guarding, and that all sources of power are fully isolated before work begins.

"The man affected by this incident faces a long road to recovery and we hope today's outcome provides him a measure of justice."

HSE guidance highlights the importance of following safe isolation and lock-off procedures before any maintenance or cleaning work is carried out. Employers must ensure all machinery is properly isolated from power sources, and that systems are regularly monitored and reviewed to prevent inadvertent start-up. Further guidance is available at:
