When dealing with a fire in a lift or escalator controller, it is crucial to avoid using a water-based fire extinguisher. This includes:
- Water extinguishers
- Foam extinguishers
- Water mist extinguishers
These types of extinguishers should not be used because they can conduct electricity, posing a risk of electric shock. Additionally, using water or foam on electrical fires can cause further damage to the electrical components and increase the fire hazard.
For electrical fires, including those in lift or escalator controllers, the appropriate fire extinguishers are:
- CO₂ (Carbon Dioxide) extinguishers
- Dry powder extinguishers
These types are non-conductive and are specifically designed for safely extinguishing fires involving electrical equipment.
