Electricity - Yleistä


General information on topic

Adequate electrical safety requires safe procedures, a responsible approach and a due respect for the dangers of electricity. Workers must be shown safe procedures and provided with appropriate tools and personal protective equipment. Manufacturers’ installation instructions must be observed.

As a rule, electrical works can only be performed by qualified electricians, and unqualified individuals should never be used for works that require a qualified professional.

The risks and adverse effects of electrical equipment, the use of electricity and static electricity in the workplace must be minimised. Electrical works may only be performed under a manager’s supervision, by competent individuals, in appropriate spaces and using appropriate equipment. The workers also need to be familiar with the applicable laws and regulations.

Electrical works carried out in the course of construction projects need to satisfy, among others, the following requirements:

  • all electrical devices must be protected against mechanical damage
  • all electrical devices must be positioned so that they cannot be tripped on, and
  • sufficient safety distances or shields must be applied when working with uninsulated wires.

Safety distances and shields to protect workers from injury also need to be in place while cranes and other machinery are in operation.

The law also lays down minimum distances to power lines during tree felling. No machinery, equipment or loads must penetrate the safety zone. In addition, the harvested timber must be stacked far enough away from power lines to maintain the required minimum distance between loading equipment and power lines.

The body responsible for ensuring electrical safety and supervising manufacturers, importers and retailers of electrical devices in Finland is the Finnish Safety and Chemicals Agency, which also issues regulations for the industry.
