7. Complete the secondary survey if possible, vital signs,
collection of information.

If it is an accident caused by a broken power line
(overhead wire, underground cable) or by an
accidentally electrified object:
• Do not touch anyone who is in contact with the power
line or any other electrified object. There is no sure
way to determine whether all danger has subsided.
• Immediately call the police department, the fire
department or Hydro-Québec’s customer service,
which will dispatch an emergency crew. Continue to
monitor the electrical source in order to prevent other
• Prohibit access to the site.
• Do not try to move the power line(s), even using
wooden objects. Wood may conduct electricity
because of the moisture it contains, or even the sweat
on the hands of the person holding it.

Interventions for electrical burns
Electrical burns, even ones whose external appearance
seems minor may cause very serious internal injuries and
serious heart rhythm problems. The victim may also be
thrown or suffer from violent muscle twitching due to the
power of the current. Even if the injury is apparent only at
the electrical current entry and exit points, the first aider
must constantly supervise the victim because the risks of
trauma and complications are high. For this reason, all
electrical burn victims require transport by ambulance
and medical assessment.
1. Make sure that the situation involves no danger and
