| Runaway
lift truck hits sweeper. |
| A mechanic was
operating a battery-powered lift truck for the test after finishing
repairs on the malfunctioned controller. The truck started to run away all
of sudden and hit a nearby sweeper, causing her an injury of three months.
Wrong wiring he made by mistake was to blame for the accident.
