Occupational safety and prevention of electrical accidents is always a matter of concern for businesses and workers. Unlike mechanical accidents, the risks of electrical accidents are difficult to detect through hearing and sight. Electrical accidents are only known when incidents occur due to the contact of a charged material. In order to avoid the risk of electrical incidents and accidents from occurring, employers and individual workers need to attend training courses on electricity safety and incident prevention.
The organization of safety training courses for workers and electricity users is simple but the quality and content of the courses are still questionable. This exists due to the failure to fully understand the Government regulations, training curriculum framework, training content, and conditions for issuing electricity safety cards. Although the search of Government documents regulating labor safety and preventing accidents caused by electricity is easy, not all individuals and organizations actively learn. As a unit specializing in consulting, designing and constructing of electrical and mechanical works with the desire to create safe and sustainable values for customers, Galaxy M&E would like to send to readers the detailed regulations of the Government regarding training, ranking and issuance of electrical safety tags.
