In the event a vehicle is the cause of damage to a power pole or any emergency situations, the result may bring down the attached lines. These lines are active and the surrounding area can be energised. A HAZARD AREA must be established until electrical authorities disconnect power.
WARNING! If power lines are broken the two halves of the line are still energised and a safe distance must still be maintained from both sections or electrocution could occur.
Always assume the conductor is alive until proven de-energised.
Do not touch wire or car as you could experience ground potential (shock).
On the arrival at a structure fire, identification of power lines and connection to property must be located and identified; procedures for active live power isolation and disconnection should be followed.
When circumstances require access to the property before power has been disconnected use the GLM MINI to determine live power areas. Examples of the areas are:
NOTE: Because the property is still live the high setting on the GLM MINI may be detecting other voltage sources such as wires in the roof or walls or the adjacent property. To overcome this use the low setting on the detector and more accurate location of AC voltage sources can be determined. By placing your hand in the middle of the unit not covering the front test area label, sensitivity is decreased providing an accurate location of voltage.
The voltage to a property may be officially disconnected by supply authority. This may not always be the case as faults in the electrical network may cause residual voltages to be carried in water pipes and neutral link connections. Suspect locations such as those involving drugs may be acquiring power from neighbouring locations or generator units these supplies may not be disconnected. These voltages may be low but the current high. Use the GLM MINI to verify voltage at all instances.
Do not enter switch yards or transformer rooms unless authorised by supply authority. These contain high and extra high voltage lines, which may arc over to the human body or equipment.
Transformer units located on ground level and pole tops contain large amounts of oil which in faulty units may leak. This oil is a conductor and may be electrically energised. Take care to never become enveloped with this oil.
Structures such as these contain voltage sources and can be detected by the GLM MINI using the above procedures.
In all natural disasters electricity is a major concern, as fallen power lines and water make a dangerous mix. The GLM MINI can be used in all of these situations.
The GLM MINI will not detect submerged power cables as water decreases the electromagnetic field generated.
In all emergency situations, always assume line is energised on initial test. Never assume de-energised lines will remain in that state.
