1.13 Specific Hazards
1.13.1 Electrical Energy
External Considerations and hazards
When working with the plant, maintain a safe distance from overhead electric lines.
If work is to be carried out close to overhead lines, the working equipment must be
kept well away from them. Check out the prescribed safety distances.
If in Doubt Ask.
If your plant comes into contact with a live wire
x Vacate the area
x Warn others against approaching and touching the plant
x Report the incident and have the live wire de-energized.
Machine - Electrical
Work on the electrical system or equipment may only be carried out by a skilled and
qualified electrician or by specially instructed personnel under the control and
supervision of such an electrician and in accordance with applicable electrical
engineering rules.
The power supply to the plants, on which inspection, maintenance and repair work is
to be carried out must be isolated before starting any work, check the de-energised
parts for presence of power and ground or short circuit them in addition to insulating
adjacent live parts and elements.
The electrical equipment of the plant is to be inspected and checked at regular
intervals. Defects such as loose connections or scorched or otherwise damaged
cables must be rectified immediately.
If working on live parts and elements cannot be avoided this must only be carried
out in the presence of a second person, who can cut off the power supply in the
case of danger by actuating the emergency shut off or main power switch. Secure
the working area with a red and white safety chain and a warning sign. Use
insulated tools only.
Use only original fuses with the specified current rating. Switch off the plant
immediately if trouble occurs in the electrical system.
This plant is wired on a negative earth. Always observe correct polarity.
Battery
x Always disconnect battery leads before carrying out any maintenance to the
electrical system.
x Recharge the battery in a well ventilated area
x The battery contains sulphuric acid, an electrolyte which can cause severe
burns and produce explosive gases.
x Avoid contact with the skin, eyes or clothing.
x No Smoking when maintaining Battery.
1.13.2 Gas, Dust, Steam, Smoke and Noise
Always operate internal combustion engines out of doors or in a well ventilated area.
If plant is operated for maintenance purposes in an enclosed area, ensure that there
is sufficient ventilation or provide forced ventilation.
Observe the regulations in force at the respective site.
Dust found on the plant or produced during work on the plant should be removed by
extraction, not blowing.
Dust waste should be dampened, placed in a sealed container and marked, to
ensure safe disposal.
Welding or naked flames
Never carry out welding, flame cutting and grinding work on the plant only if this has
been expressly authorised, as there may be a risk of explosion and fire.
Before carrying out welding, flame cutting and grinding operations, clean the plant
and its surroundings from dust and other inflammable substances and make sure
the premises are adequately ventilated (as there may be a risk of explosion).
Avoid all naked flames in the vicinity of this equipment
Personal Protection
Ensure that the operators are provided with hearing protection of approved pattern
and that these are worn at all times when the plant is operating.
Ensure operators wear a suitable face mask where exposed to possible harmful
effects of air pollution of any kind.
