Petrol fumes, for example, are heavier than air and can thus run
down a sloping grade or down into a grease pit where, for example,
welding flames can cause an explosion. Evaporated petrol has a
very powerful explosive force.
Special cases
Diesel fuel with added petrol has a reduced flash point. There is an
explosion risk even at room temperature. The explosion risk due to
warmed diesel fuel is greater than for petrol.
When changing oil in the engine, hydraulic system, and transmis‐
sion, keep in mind that the oil can be hot and may cause burn inju‐
ries.
Welding on or near the machine constitutes a fire hazard: if diesel or
other oils have leaked out and have been absorbed by rags,
absorbing agent, paper, or other porous material, welding sparks
can cause ignition and an explosive spread of fire.
When charging the battery, the battery electrolyte emits oxygen and
hydrogen gas. This mixture is highly explosive. The risk of explosion
is especially high when a booster battery or a rapid charge unit is
used, as these increase the risk of sparks.
Today's machines contain a lot of electronic equipment. The control
units must be disconnected and the main switch must be off when
welding. Otherwise, strong welding currents can shortcircuit the
electronics, destroy expensive equipment, and cause an explosion
or fire.
Never weld painted surfaces. Remove the paint at least 200 mm
around the welding or cutting point. Use gloves, respiratory protec‐
tion, and protective safety glasses when sand blasting and welding
the damaged item. Also, welding work must never take place near
plastic or rubber materials without first protecting them from the
heat. Paints, plastics, and rubber generate various substances that
may be hazardous to health when heated. Be careful with machines
that have been exposed to intense heat or fire.
Precautions
•
Store explosive substances in approved and sealed containers.
•
Make sure that there are no ignition sources near flammable or
explosive substances.
•
Make sure that ventilation is adequate or there is an air extrac‐
tion unit when handling flammable substances.
Fluid or gas under pressure
Pressure lines can be damaged during work, and fluid or gas can
stream out.
There may be high pressure in a line even if the pump has stopped.
Open the pipe or hose connection of the damaged pressure line
carefully, as liquid or gas under high pressure can flow from the
connection.
Risks
There are injury risks in connection with work on:
