  • Why You should take this seminar

    A benefit of electrical safety training is to provide your employees (qualified and non-qualified workers) with the education they need to complete their job duties safely. According to the US Department of Labor, electrocution is one of the main causes of on-the-job deaths of industrial workers. Within this group, skilled trades’ personnel—electricians in particular—are two times more likely to be seriously injured or killed than non-skilled trades.
