If you are about to start with the business, then the thing which will matter a lot in this regards is the cost. But, make sure that you do not put the cost on top of the safety of your employees. So, whenever you hire an employee make sure that he has undergone the High Voltage Training. You cannot compromise with the safety. The hiring of a person who has not undergone the High Voltage Training is not a threat to your company but to other employees as well. An inexperienced worker may work well in the organization, but a person who is not focused may not be able to do well in your business.
If you think that a person has the caliber to do well, then it is your responsibility to make him go through the High Voltage Training, so that it can be proved as a boon for your organization. There is no way that you can put the health of other employees in danger on the cost of a single employee. Hence, it is very important that the candidate undergoes the High Voltage Training before he starts up with the career.
