Carbon monoxide poisoning
Only start the engine in a well-ventilated area. If oper-
ating the engine in an enclosed space, ensure that
exhaust gases and crankcase emissions are ventilat-
ed out of the working area.
Chemicals
Most chemicals such as glycol, rustproofing agents,
inhibiting oils and degreasing agents are hazardous to
health. Read and follow the instructions on packag-
ing.
Certain chemicals such as inhibiting oils are inflam-
mable and also hazardous to health if inhaled. Ensure
that ventilation in the workplace is good and use a
protective mask when spraying. Read and follow the
instructions on packaging.
Store chemicals and other hazardous material away
from children. Deposit excess or used chemicals at a
properly designated disposal site.
Cooling system
There is a risk of water penetration when working on
the seawater system. Turn off the engine and close
the sea cock before starting work on the system.
Avoid opening the coolant filler cap when the engine
is hot. Steam or hot coolant can spray out and cause
burns.
If work must be carried out with the engine at operat-
ing temperature and the coolant filler cap or a cock
open or a coolant hose disconnected, open the cool-
ant filler cap carefully and slowly to release pressure
before removing the cap completely. Note that the
coolant may still be hot and can cause burns.
Lubrication system
Hot oil can cause burns. Avoid skin contact with hot
oil. Ensure that the lubrication system is not under
pressure before commencing work on it. Never start
or operate the engine with the oil filler cap removed,
otherwise oil could be ejected.
Fuel system
Always use protective gloves when tracing leaks.
Liquids ejected under pressure can penetrate body
tissue and cause serious injury. There is a danger of
blood poisoning.
Always cover the generator if it is located under the
fuel filter. The generator can be damaged by spilled
fuel.
Electrical system
Cutting off power
Always stop the engine and break the current using
the main switches before working on the electrical
system. Isolate shore current to the engine block
heater, battery charger, or accessories mounted on
the engine.
Batteries
The batteries contain an extremely corrosive electro-
lyte. Protect your skin and clothes when charging or
handling batteries. Always use protective goggles
and gloves.
If battery electrolyte comes into contact with unpro-
tected skin wash off immediately using plenty of wa-
ter and soap. If battery acid comes into contact with
the eyes, flush immediately with plenty of water and
obtain medical assistance without delay.
