When working on ignition systems
When working on controlled ignition sytems, make sure the engine is off
before connecting cables and sampling probes in order to avoid accidental
discharges that could seriously injure persons or seriously damage the
electronic systems being tested. High voltage discharges, which are typical
in ignition systems, may cause fatal injuries, especially to pacemaker
patients.
When working on the batteries
Car batteries contain sulphuric acid and produce explosive gases; please
follow the instructions carefully:
-
Always wear safety glasses.
-
Never leave tools on the battery; they could cause accidental contacts.
-
Before proceeding with the test or recharging, cover the openings of the
battery with a wet cloth in order to suffocate explosive gases.
-
Avoid causing sparks when cables are being connected to the battery.
-
Avoid splashing electrolyte on skin, eyes and clothes, as it is a corrosive and
highly toxic compound.
While working with appliances powered by the mains
Make sure the appliance is grounded.
Cut power before connecting or disconnecting cables.
Avoid contact with wet hands.
Make sure you are well insulated from the ground when handling the tools.
