Safety grounding Connection of the external metal parts of electrical appliances to earth Function In the event of a defect in an electrical appliance, external metals are prevented from becoming live Rule When grounding, connect as much as possible to the existing ground network Scaffolding and residual-current device Grounding of scaffolding is mandatory when there are electrical cables, pipes and/or electrical equipment (such as hand tools) on and/or attached to the scaffolding that are under a non-safe voltage Electrical safety measure that must be taken for containers Connect according to regulations Safety measures before working with electrical equipment Visually check for damage and deviations Report damage and do not use damaged equipment Protection value of the earth leakage circuit breaker in the construction power connection box for extra safety 30 mA earth leakage circuit breaker (per outgoing power supply) Danger (cable reels) If a cable reel is not completely unwound during use, it can become very hot due to heating and cause a fire. Safety measures (cable reels) - When using, always respect the maximum allowable power of the reel in rolled and unrolled condition Dangers and safety measures when using temporary electrical equipment

-

Unwind the cable reel completely

Danger (power and extension cables) Overloading the cable

Safety measure (power and extension cables) Ensure that the power supply or extension cable is suitable for the power of the connected devices Protections on the enclosures - Double insulation (insert sign) does not protect against penetration of moisture and dust - Protection against penetration of moisture (e.g. rain) - Protection against ingress of dust - Protection against impacts and falling objects Static electricity and safety measures Definition Build-up of electrical voltage differently than in regular electricity systems Situations with a risk of static electricity - Rising gas or vapor bubbles that cause turbulence - When spraying paint or other equivalent activities - Rubbing plastic - Pneumatic transport of powders and granules in mixers, dosing locks of weighing bunkers, tankers

- -

Friction from clothing on the skin

Drive belts

- With some liquids, when flowing through a plastic pipe or when stirring - Walking on a plastic floor covering

Hazards -

Static electricity discharge can result in arcing - Electronic equipment can be damaged by static discharges Measures to reduce static electricity - Ground pipelines, equipment and tanks
