LOOK UP LOOK OUT BEFORE YOU LIFT YOUR LOAD
In 2006 there were 3 dump truck related deaths in Ontario.
Dump truck drivers and construction workers must ensure they are aware of the location and voltage of overhead powerlines where they are working. Most overhead powerlines are not insulated. Metal objects that contact these lines become energized to the same voltage as the line. Dump trucks are included. Tires can act as an insulator until they blow. At this time the vehicle and the ground around it will become energized. If tires do not blow drivers should check these for damage.
The Electrical Safety Authority (ESA) recommends that drivers and workers maintain a distance of more than 10 feet from powerlines on poles. The Occupational Health & Safety Act & Regulations mandate the safe limits of approach to overhead powerlines based on voltage ratings.
Drivers and workers must be made aware of overhead powerline hazards and know what safe limits of approach to adhere to. Caution should be taken not only when lifting the dump truck box – but also when lowering this to avoid unexpected contact with overhead powerlines.
In the event that your vehicle comes in contact with a powerline – A driver can be electrocuted if he/she attempts to leave the truck. Warn others to Stay Back! If someone were to touch the side of the truck they would be electrocuted by the energized dump truck. In 2006 three people were electrocuted as a result of dump truck contact with a powerline.
In addition the ground around an energized vehicle will carry electricity for up to 35 feet.
In the event of a powerline call 911 or the Local Distribution Company (Electrical Utility) to ensure that power on the powerline is disconnected.
