A stevedore had to be taken to hospital after handling cans of fumigant on cargo ship Thorco Angela (IMO 9359935) in Liverpool on October 10th 2021, when dockers subcontracted to Peel Ports started cargo discharge.
In July 2021, 8000 tonnes of bagged sweet potato product were loaded into the cargo holds of the Thorco Angela in Rizhao, China. While loading, shore stevedores and, at a later time during the load, Thorco Angela’s crew, placed cans and pouches of aluminium phosphide fumigant between the bags of cargo.
On July 19th the vessel departed Rizhao for northern Europe, carrying out scheduled crew changes during the voyage that included the master, chief officer, second officer and third officer.
At 17:45 local time on October 10th, Thorco Angela berthed in Liverpool, England. At 19:55 stevedores subcontracted to Peel Ports Liverpool started cargo discharge. The stevedores found open cans containing powder among the cargo and alerted their supervisor. At 22:00 the cargo work was suspended and the stevedores waited in a mess room on the quay.
During the early hours of October 11th one of the stevedores became unwell and was taken to hospital. He was suffering with nausea, loss of balance, and nerve damage to his hand. The man had an extended absence from work while recuperating. After the accident, Thorco Angela’s crew removed some of the fumigant from the cargo holds. A specialist contractor subsequently removed 150kg of fumigant from Thorco Angela’s cargo holds.
A preliminary assessment by the Marine Accident Investigation Branch identified that:
- The fumigant was provided to Thorco Angela by one of the cargo suppliers, but it was likely that specialist fumigators were not allowed to board Thorco Angela and deploy the fumigant due to the Covid-19 restrictions that were in force in Rizhao. Thorco Angela’s crew were not trained to deploy or remove the fumigant and the personal protective equipment they were wearing was inadequate for the task.
- Thorco Angela’s officers did not adhere to the company’s safety management system (SMS) or international guidelines on the use of fumigants. Consequently, the fumigant was incorrectly deployed and did not fully volatilise and disperse during the voyage to the UK.
- The use of the fumigant in the cargo holds was neither documented on board Thorco Angela, nor communicated to Peel Ports Liverpool by Thorco Angela’s master, voyage charterer, or ship management company before the vessel’s arrival. Therefore Peel Ports Liverpool was unaware of the presence of fumigant on board Thorco Angela, consequent to which it did not initiate its fumigant removal protocols before clearing the vessel to start discharging cargo.
- The risk presented by the cans of fumigant was underestimated when they were first found, which delayed the cessation of cargo discharge, and Peel Port’s emergency response procedure was not strictly followed.
- The stevedore ingested fumigant either while working cargo or while eating and smoking after leaving Thorco Angela.
As a result of the MAIB’s preliminary assessment, The Chief Inspector of Marine Accidents has written to Peel Ports Liverpool advising them of the safety issues identified and highlighted the guidance regarding fumigated cargo emergency response planning detailed in the Department for Transport publication A Guide to Good Practice on Port Marine Operations.
The Chief Inspector has also written to Auerbach MARINE GmbH & Co. KG notifying them of the shortfalls in Thorco Angela’s officers’ actions and the failure of the company SMS.
Peel Ports Liverpool has carried out an internal investigation into the accident and committed to the addition of cargo fumigation status to its vessel cargo work checklist and development of fumigation awareness training for its management, supervisors, and stevedores.
Auerbach MARINE GmbH & Co. KG was yet to advise the MAIB of the actions taken in response to this accident.
