Protect your bottom line and your lifeline
A little planning and preparation before construction begins can save you from costly delays, fines and repairs. More importantly, planning can prevent needless injury and even death.
Keep your distance
Check with NB Power to identify voltages on any overhead lines and find out how close you can safely work near the lines. If you must conduct work near overhead lines, call NB Power first to assess the area. NB Power can insulate or deactivate the lines to make the area safer to work in.
Minimum safe distances:
Up to 750 volts - 0.9 metres (3 feet)
751 to 100 000 volts - 3.6 metres (12 feet)
100 001 to 250 000 volts - 5.2 metres (17 feet)
250 001 to 345 000 volts - 6.1 metres (20 feet)
Call before you dig
Hitting or damaging underground electric cables can be just as dangerous as touching overhead lines, resulting in serious injury or death. To avoid contact with underground lines, call NB Power at least two working days before work is scheduled to begin. NB Power can come to the job site and mark the location of underground wiring.
Worksite safety tips
Use caution when moving equipment or tools around overhead lines. This includes cranes, backhoes, scaffolding, or long lengths of pipe. Never get closer than the miniumum safe distance.
Use a designated signaller who knows the minimum safe distances to help equipment operators steer clear of overhead lines.
Remember, the minimum safe distances apply to anything that can possibly reach, slip, or fall from the work area. Increase your working distance whenever you're using equipment that can fall or collapse, such as booms, cranes, ladders and scaffolds.
Keep hazards and the minimum safe distances well marked with signs provided by NB Power.
If the minimum safe distances can't be maintained when moving equipment around lines, take another route or call NB Power.
If you must work within close proximity to power lines call NB Power to deactivate/deenergize the lines or insulate the wires prior to commencing the work.
Workers should keep clear of all big equipment/machines working around power lines.
Locator flags can tell you where the underground cables are located but not how deeply they are buried. Hand digging only, using safe techniques, must be used to determine the exact location of the cables, prior to beginning any machine digging operation.
What to do if you accidentally contact the lines
Call 911 and NB Power (1 800 663-6272)
If possible, try and drive a safe distance away from any fallen line (10 metres/33 feet). If you cannot safely stay clear, stay on the equipment or in the vehicle until an NB Power representative says it is safe to get off.
If your vehicle is on fire, open the doors as wide as you can, while keeping your feet inside, then put both feet together at the edge of the opening and jump at least 0.6 - 0.9 metres (2-3 feet) clear of the vehicle with both feet together.
NEVER TOUCH THE GROUND AND THE VEHICLE AT THE SAME TIME.
Move 10 metres (33 feet) away by keeping both feet on the ground and shuffling your feet or by jumping with both feet together. This prevents you from becoming a part of the electrical circuit, avoiding serious injury or death.
Touching someone in contact with electricity could shock you as well. If a co-worker touches a power line stay clear and call 911 and NB Power. Also keep other workers away from the area to avoid electrocution.

TASKS
- Reading comprehension:
- What are “shoring to walls and faces”?
- What risks may be involved in using compressed air machinery?
- What parts of the body might be affected?
- Is there any difference between “isolated conductors” and “insulated conductors”? (As in “never use a metal ladder adjacent to suspended electrical conductors unless they have been…”)
- According to the context, what may possibly mean to protrude? (As in “the ladder is long enough … and protrudes at least one metre…”)

Fall from mobile crane bucket during descending [Description of the Accident]
This accident occurred during work to dismantle some suspended scaffolding that had been used to carry out repair work on a signboard.
The work was started by using a mobile crane to lower the beam33 that had supported the suspended scaffolding. In order to remove the scaffolding flooring, the victim then rode the bucket of the mobile crane and started to sling34 and lower the flooring to the ground by the crane.
During this operation, the bucket carrying the scaffolding got caught on an angle fitting used to support the signboard, and the victim tried to free the bucket by swinging it back and forth35.
Immediately thereafter, the bucket came loose from the hook of the crane and the victim fell to the ground.
[Causes supposed]
- The operator of the crane lifted the bucket while the victim was riding atop36 the suspended scaffolding in the bucket.
- When trying to free up the caught flooring, the worker rode atop the suspended scaffolding flooring while swinging the bucket back and forth.
- Adequate arrangements were not made in advance regarding the working methods, etc., to be used in dismantling and removing the scaffolding.
[Type of business] Other building construction work
