3.1 - GENERAL SAFETY AND SPECIFIC INTERVENTIONS ON MOTOR
The technician should take all steps to protect themselves or others against all risks of injury inherent in his
intervention.
The technician should ensure they have the PPE (personal protective equipment) suitable for the job and the
particular conditions of environment in witch the material can be found (see safety information specific to the
operation site).
• Turn off the ignition, remove the key, open the battery switch before working on the engine.
• Accidental engine starting can cause injury or death to personnel working on the equipment. To avoid
accidental engine starting, disconnect the battery cable from the negative (-) battery terminal.
Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact
with other metal surfaces which could activate the engine electrical system. Place a do not operate
tag at the start/stop switch location to inform personnel that the equipment is being worked on.
• The hot engine parts can cause injury and burns. Before performing maintenance on the engine, cool
the engine and parts.
• By touching a functioning engine, there is a risk of burns from contact with hot parts, and injuries by
the rotating parts.
• To avoid any risk of accident, using compressed air (example : blowing air filter), always wear a
headband and goggles.
• The hot coolant, steam and alkalis can cause injury. At the operating temperature, the engine coolant
is hot and under pressure. Do not open the cap of the expansion chamber before letting the circuit
cool.
• The radiator and all the pipes going to the heaters or engine contain hot coolant or steam. Contact
can cause severe burns.
The engine exhaust gases contain harmful combustion products. Always start and run the engine in a well
ventilated area. In an enclosed area, evacuate the exhaust outside.
