6 FAQs about [Hazards of not storing energy in switchgear]
Is working with electrical switchgear dangerous?
Working with electrical switchgear inherently carries risks, including the possibility of electrical shocks, arc flashes, and other hazards. Therefore, adhering to stringent safety procedures is an absolute necessity.
Why do electrical switchgear maintenance and safety go hand-in-hand?
Below are some reasons why maintenance and safety go hand-in-hand: Reduced Risk of Electrical Accidents: Regular maintenance of main electrical switchgear helps identify and address electrical issues before they escalate into accidents.
What are the risks associated with the use of switchgear?
The risks associated with the use of this type of switchgear have been described in paragraphs 24−26. Even in situations where the equipment is known to be in good condition and its use is restricted to appropriately trained people, its live operation creates a foreseeable risk of injury. Safety is dependent on the physical actions of the operator.
Is switchgear a safety hazard?
The absence or failure of switchgear can lead to safety hazards, as exemplified by a case at a metal processing plant where a lack of proper documentation resulted in a serious risk to service technicians. The importance of reliable switchgear is further emphasized by the necessity for hazard assessment in the workplace.
Are old switchgear installations dangerous?
Older types of switchgear have with time been proven to be deficient in some areas. This together with changing system fault levels and poor or no maintenance can lead to high safety risks to personnel in aged switchgear installations.
