3.5.1 Safely dealing with sources of danger
The following describes the various forms of danger that can occur during machine operation.
Exhaust fumes
Exhaust gases from combustion engines contain carbon monoxide, a color- and odor- less but
highly toxic gas. The inhalation of minute quantities can be lethal.
Furthermore, diesel exhaust contains soot particles, some of which are noxious.
➤
Do not inhale exhaust fumes.
➤ Park the machine in such a manner that the exhaust cannot blow towards the operators.
➤ Never use the machine in enclosed spaces, only in the open.
Fire and explosion
Spontaneous ignition and combustion of fuel can result in serious injury or death.
➤ Do not allow open flames or sparks at the place of use.
➤ Do not smoke while refueling.
➤ Never refuel the machine when it is running.
➤ Do not allow fuel to overflow.
➤ Wipe up spilled fuel immediately.
➤ Provide a fire extinguisher in the immediate vicinity.
➤ For operation in combustible environment, fit the machine with an exhaust silencer (Option la).
Hot coolant
The cooling system of a liquid-cooled engine at running temperature is under high pressure. Cool‐
ant can spray out when the filler cap is opened causing severe burns.
➤ Let the machine cool down before opening the cooling system.
➤ Unscrew the filler cap carefully by a quarter to half a turn at first. Remove the filler cap only
when pressure has escaped completely.
Electricity
Touching voltage-carrying components can result in electric shocks, burns, or death.
➤ Allow only qualified and authorized electricians or trained personnel under the supervision of a
qualified and authorized electrician to carry out work on electrical equipment according to elec‐
trical engineering regulations.
➤ Check regularly that all electrical connections are tight and in proper condition.
➤ Switch off any external power sources.
For example, the connections to the electrical engine cooling water pre-heater.
Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns work on components that could be under pressure.
➤ Wait until the compressor has automatically vented. (Check the pressure gauge: it must read 0
psig!)
