6 to 10 people die annually, with 100s more injured through
lightning injury. It is reported that around 80 instances
of Lightning injury relates to the use of fixed telephone systems
Under Section 19(1)(a) of the Occupational
Safety and Health Act, employers have a duty of care
to ensure, as far as practicable, that employees are not exposed
to hazards at the workplace.
Three basic steps should be
taken to ensure a safe and healthy workplace.
They are based
on the concept that the workplace should be modified to suit people,
not vice versa. The three steps are:
the hazards - involves recognising things which may cause injury
or harm to the health of a person, for instance potential exposure
to harm, flammable materials, ignition sources, unguarded machinery,
and even Lightning;
• Assessing the risk
- involves looking at the possibility of injury or harm occurring
to a person if exposed to the hazard;
Controlling the risk - by introducing measures which will eliminate
or reduce the risk of a person being exposed to a hazard.
It is important to regularly review these steps, especially
if there are changes in the work environment, where new technology
is introduced, or where standards are changed.
In recent years
there have been a number of significant incidents in Australia,
relating to the dangers of personnel working during localised thunderstorm
These incidents have affected Mining Operators, Sporting
organizations, Electrical Utilities, Vineyard workers, Construction
Workers, Schoolchildren, and office workers using telephones.
Australian Standard AS1768-2003 “Lightning Protection” recommends
the use of Lightning detection devices to provide guidance as to
when conditions are becoming unsafe for workplace and recreational

with Intelicharge uses
a proprietary technology to detect and determine the distance to
severe weather, which is virtually always indicated by lightning
activity. Through the application of advanced electronics and proprietary
software, its high sensitivity, single-channel receiver detects
electro-magnetic field emissions from lightning activity within
a storm cell.
Thunderbolt 2 then converts this data into digital
signals and feeds them to its microprocessor for analysis. In addition
to identifying the waveforms characteristic of storm activity, Thunderbolt
performs continuous analysis of background electromagnetic interference
(EMI) at the user location. This function is critical for minimizing
false-triggering from non-storm noise sources, and maintaining accuracy
of storm data. A computer analyzes the detected energy levels on
the frequencies observed, and then calculates the real distance
in kilometres to the detected storm activity. In a fraction of a
second, the Thunderbolt 2 displays warning information on its LCD
The distance to storm activity,
Time of Arrival (ETA) measured from the users location
Just as important as ETA, is the ETC
“Estimated Time to Clear” information which is monitored continuously
with 15 second data updates. Flashing LEDs and an audible alarm
provide warning. ThunderBolt 2’s LCD continuously displays the time
until the storm clears the area for safe resumption of work or activity,
with the least downtime and maximum productivity.
detects, identifies and tracks storm activity sufficiently intense
to generate lightning within 100 kilometres of the users location.
Thunderbolt 2 operates in excess of 75 hours on a single 9-volt battery
that can be charged at any 220VAC power outlet.
A 220 VAC low-noise charger and a hard carrying case are also included in the standard ThunderBolt
2 package. Additional accessories such as a DC charger, desk
stand or multi-purpose wall mount for permanent installation can
The Thunderbolt is ideal for:
_ Drill and Blast crews
Scientists and Technicians
_ Heavy equipment
_ Electrical workers and Linesmen
and recreation clubs
_ Boating enthusiasts
and outdoor activities
Note: The standard
package includes Main Unit, Hard Carry Case, AC
Charger & Battery
DC Charger, Belt
Pouch, Wall Mount & Desk Mount are optional extras

Hand held detectors
such as the Thunderbolt 2 detect the unique radio frequency signatures
associated with already active lightning.
Such devices CANNOT
predict a first strike, or monitor any of the measurable conditions
leading up to a first strike.
Those who may
look to use the benefits of hand held detection technology, must
do so knowing that the devices have these limitations, and
in every instance when the detector alerts, that certain safety
procedures must be immediately enacted, such as communicating the
lightning warning to those who may be at risk, and direct those
at risk immediately find a safe area, until such time as threat
has seen to have passed.
The use of Lightning detection equipment should
be used in conjunction with the 30 /30 rule ( refer
The 30/30 Rule
It is recommended
that the use of any Lightning Warning or detection systems be used
strictly under a Lightning safety policy which describes the known
safe locations where persons should wait out the threat, and highlights
those unsafe locations where persons should seek to avoid.
