Quick Assessment
Use the table to make quick assessment of installations :

- At your arrival
- When renting a new place
Available on kitlog online
Useful to do a quick assessment
of the 5 essential safety rules



If the building is noted :
• 0 to 3 / 10 : Building need emergency works, HQ advisor must be notified
• 4 to 7 / 10 : Works are to be planned. It is necessary to plan adapted
budgets to perform it during the next 6 months
• 8 to 10 / 10 : The building is at minimum standard level. You can plan small
works to improve user’s safety conditions

Basic safety rule #1
No possibilty of direct contact = 1 pt
 That happens especially with
detached switches and outlets,
when an equipment is removed
and not replaced, on bad
connection of two wires
 If you notice nude wires or any
possibility of direct contact, you
have to make works to avoid them

Basic safety rule #1
 As a vehicle, an electrical installation need a maintenance
 That must be planned and budgeted :
City apartment
300 à 500 €

Individual building
1000 €
Isolated Compound
1500 €

Basic safety rule #2
No electricity more close than 1,5 m from water
No wire, socket, switch or electrical equipment of any kind
That concerns bathrooms,
kitchens, any room with tap, …
And also water dispensor !
Because of possible leackage
Water
Computer
UPS
Photocopier

Basic safety rule #2
Whatever skills or countries, a local electrician is able to create a
new socket outlet and to disconnect and seal the old one.
Do not wait the incident
or somebody obliges you to do it !
=> Remove these items from water immediately

Basic safety rule #3
Electrical panel (switch board) = 3pts
Building must have an electrical switch board
Correctly fixed, without signs of burn
With adapted protections

Basic safety rule #3
All equipement must be protected
by circuit breaker or fuses
 If you don’t have any circuit-breaker or
fuses on your building, your situation is
an emergency. You have to contact an
electrician to make works, or the HQ
referent at least
 If you have, make a test : switch all
them off and verify if some equipment
still supplied. If yes, that means that
they are not protected. You have to
contact an electrician to make works

Basic safety rule #4
Size of cables = 1 pt

Basic safety rule #4
Wires have to respect minimum standard sizes
 An under-sized cable if hot, and can burn. If you don’t have any
electrical notion, but you touch a wire and you feel it is hot, it is
not normal ! and you have to change it.
 That mainly happens with heavy equipment (boilers, heaters, air
conditioning, …), with long wires, and with overload multi-plugs.
 Wire undersized is the first cause of fire starts !
 Please refer to electrical and saftey guidelines
to choose the size of wires.

Basic safety rule #5
Equipment using water or made of a steel frame
must be connect to the earth = 2 pts
 To verify it, you can buy an outlet tester =>
 If you don’t have earth connection on
heavy equipment and equipment with
steel frame, you must contact an electrician to install it.

Be careful if you want to verify it without tester : to have an earth
cable in you socket outlet don’t mean that this cable is connecter to
this earth.

If you don’t have earth connection on your building, the minimum
protection you can install is a differential circuit breaker

Basic safety rule #General
If you have any doubt, don’t touch…
…and ask a local electrician or the HQ
Most of the time, send a picture will be enough to :
 Identify and evaluate the problem
 Explain what works to do and how
 Plan incoming costs, …
 To not care of installation maintenance is like
transform maintenance operation in renewal
operation
 Renewal costs are often heavy and can not be
taken in charge by the mission

Panneaux de raccordement
Local Grid
• Power sheddings (power cuts)
 Identify the shedding length and frequency
 Keep in mind : A battery need need 4 to 8hr of charging
 Obligation to have an emergency power source
• Fluctuations
 Buld intensity fluctuations, Fluorescent bulds what not works
correctly, UPS beeping when bulds still illuminated, …
 Small stabilizer on Equipment to protect
Heavy stabilizer on the full building
• Voltage peaks (surges)
 Surge protector :

Frequent Problems
Mainly caused by …
Voltage fluctuation
Overload
Overload on one phase (3-phase only)
Alternator regulator problem
Permanent low voltage
Alternator problem
Low voltage shutdown
or High Temperature shutdown
Overload
Bad ventilation
Fuel leaks
Bad fuel quality
Obligations :
=> Dispose the logbook next to the generator
=> Stand at attention about fuel consumption
Recommendations :
=> Oil change every 250 hours
=> Heavy maintenance each 2500 to 3000 hours

Keep in mind
 Almost nothing can be done without a energy supply :
=> have a proper back-up
 Do not forget the maintenance of your equipment and installations
 Security and good environment practices are the same everywhere
in the world
 While buying equipment:
• Take time to assess your needs
• Take into account total life-cycle cost (fuel, maintenance, disposal…)
and not only initial cost
 Anticipate your works and costs
 More details on the kit log
