A recent Safety Flash by the International Marine Contractors Association (IMCA), focuses on an incident, in which a smoke detector was activated, to provide lessons learned.
The incident
A deck officer checked the origin of the alarm which was coming from an area close to the laundry room. A general fire alarm was sounded; all personnel started to muster, and a firefighting team assembled.
The fire team found the source of the fire which was coming from an industrial tumble dryer in the laundry room. The fire was safely extinguished before the personnel muster was complete.
What went right
- Everyone started to muster quickly and professionally;
- The fire fighting team responded to the action area and put out the fire.

IMCA’s member noted that in this case:
- The air flow of the tumble dryer heating system may have allowed flammable material (particulate) to be conveyed through the electrical heating elements and pushed into the drum containing the clothes. The electrical elements are not protected (isolated) and are positioned very close to the actual rotating drum;
- The dryer had undergone recent maintenance (troubleshooting) and the control panel and set-up parameters had been changed during this process, and were different from the original;
- There was no smoke detection in the laundry – only heat detectors – and the alarm was by the smoke detector adjacent the door of the laundry in the corridor because the door was partially open;
- The type of tumble dryer conformed to no known industrial standard.
What were the causes
- Changes to the dryer in the troubleshooting/maintenance process;
- Lack of smoke detection in the laundry.
Lessons learned
- Use equipment complying with a recognized industrial design standard;
- Use spare parts that are either original and/or fully compatible with the equipment;
- Review fire/smoke detection system to identify potential improvements particularly in laundry area.
