Flashover Involving Cassette Cooker
(I110330003) |
| Incident |
The male householder got a cassette cooker out to prepare hot pot at home. He inserted the LPG cartridge and tried to switch on the cassette cooker. There was a flashover. The female householder rushed to get the burning cassette cooker to the bathroom to put out the fire. Her left arm suffered minor burns in the incident. |
| Cause |
Investigation found that the cassette cooker involved in the incident was purchased more than 10 years ago. It has no flame failure device and has not been properly maintained. The ageing rubber seal ring at the connection between cartridge nozzle and cooker is the cause of the gas leak. A flashover occurred when the male householder tried to switch on the gas-leaking cassette cooker. |
| Prevention Tips |
Purchase cassette cooker bearing the GU mark and follow the instructions on the LPG cartridge in handling and changing cartridges. Do not use non-approved accessories. |

Gas Leak from Cooker
(I090302001) |
| Incident |
A strange odour from a flat was detected and reported to the police by a neighbour. Firemen broke into the flat and found that the left burner of a double burner LPG cooking stove had not been switched off completely, resulting in the LPG leak. Luckily, the leak was detected in time, before any serious incident, such as fire or explosion, happened. |
| Cause |
The LPG cooking stove involved in the incident is a non-approved gas appliance (without the GU mark). Although fitted with a flame failure device, that device could not function normally. As the burner on the left is neither switched off completely nor ignited, it results in the LPG leak. |
| Prevention Tips |
Purchase gas appliances that bear the GU mark. Arrange for a registered gas contractor to conduct safety checks on the appliance once every 18 months to ensure best performance of the appliance. Check if the switch of the gas appliance is turned off properly after cooking or cleaning. |
