Electric Vehicles - Jacobsen Sand Scorpion Safety And Operation Manual

1.3 ELECTRIC VEHICLES _______________________________________________________

Electric vehicles and the batteries that power them require special precautions. Follow the safety practices
described below and throughout this manual to reduce the possibility of explosions and fire.
1. Hydrogen is explosive in concentrations as low as
4% and is generated in the charging cycle of electric
vehicles. Because it is lighter than air, it will collect
in the ceiling of buildings necessitating proper venti-
lation. Air exchanges of 5 changes per hour is con-
sidered the minimum requirement.
2. Never charge the equipment in an area that is
subject to flame or spark. Pay particular attention
to natural gas or propane water heaters and
furnaces.
3. Never smoke around batteries.
4. Use care not to tip batteries when removing or
installing them. Spilled electrolyte can cause burns
to the eyes, skin and clothing.
5. Never overfill battery. Overfilling could result in
electrolyte being expelled from the battery during
the charging cycle.

WARNING
6. Always use a dedicated 15 amp circuit for each
battery charger. Do not permit other appliances to
be plugged into the receptacle when the charger is
in operation.
7. Always check the polarity of each battery terminal
and be sure to rewire batteries correctly.
8. Always use insulated tools to remove the batteries.
This will reduce the chance of sparks caused by
shorting the battery terminals or associated wiring.
Always cover exposed battery terminals with an
insulating material.
9. Switch off all electrical accessories, turn power
switch off, remove key and disconnect battery
connector before starting work on equipment.
