Why we don't tamper with electrical mains or other fitting in the laboratory?

Tampering with electrical mains or fittings in a laboratory poses significant safety risks, including the potential for electric shock, fires, or equipment damage. Such actions can compromise the safety of personnel and disrupt ongoing experiments. Additionally, unauthorized modifications can violate safety regulations and protocols, leading to legal and institutional consequences. Therefore, it's crucial to leave any electrical work to qualified personnel to ensure a safe working environment.
