S02 SAFETY
HANDLING BATTERIES SAFELY
If not handled properly, batteries are a
potential source of hazards. Excess of
gases in batteries may explode. Keep
sparks and flames away from batteries.
Never use a cigarette lighter to observe
electrolyte level. Use a flashlight to do it.
Use a flashlight to do it. Never check battery charge
in shorting posts with a metal part. Use a voltmeter or
hydrometer.
Always remove grounded (-) battery clamp first and
replace grounded clamp last. Sulfuric acid in battery
electrolyte is poisonous and strong enough to burn skin,
eat holes in clothing, and cause blindness if splashed
into eyes.
Avoid hazards and acid burns:
• Filling batteries in a well-ventilated area
• Wearing eye protection and rubber gloves
• Avoiding use of air pressure to clean batteries
• Avoiding breathing fumes when electrolyte is
• Avoiding spilling or dripping electrolyte
• Using correct battery booster or charger
procedure.
If acid is spilled on skin or in eyes:
• Flush skin with water
• Apply baking soda or lime to help neutralize the
acid
• Flush eyes with water for 15-30 minutes.
• Get medical attention immediately.
If acid is swallowed:
• Do not induce vomiting
• Drink large amounts of water or milk, but do not
exceed 2 L (2 qt).
• Get medical attention immediately.
PREVENT BATTERY EXPLOSIONS
Keep sparks, lighted matches, and open
flame away from the top of battery. Battery
gas can explode. Never check battery
charge by placing a metal object across
the posts. Use a volt-meter or hydrometer.
Do not charge a frozen battery: it may
explode. Warm up battery to 16°C (60°F)
before doing it.
Battery posts, terminals, and related ac-
cessories contain lead and lead com-
pounds. Rinse hands after handling bat-
teries.
FROST PROTECTION - WINTERIZATION
See Maintenance Section 08 - Raw Water System - Risk
of icing conditions / Protection against frost.
When the engine has been set for winter-
ization, place “DO NOT OPERATE” labels
onto taps, valves, parts of equipment
which have been turned off. Place a large
and visible reminder on the wheelhouse
dashboard.
