Electrical safety standards

Last updated

Electrical safety is a system of organizational measures and technical means to prevent harmful and dangerous effects on workers from electric current, arcing, electromagnetic fields and static electricity.

History

The electrical safety develops with the technical progress. In 1989 OSHA [1] promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. [2] In 1994 were established Electrical Safety Foundation International non-profit organization dedicated exclusively to promoting electrical safety at home and in the workplace. [3]

Standards are compared with those of IEEE and National Fire Protection Association. [4] [5]

Lightning and earthing protection

Lightning and Earthing protection systems are essential for the protection of humans, structures, protecting buildings from mechanical destruction caused by lightning effects and the associated risk of fire, Transmission lines, and electrical equipment from electric shock and Overcurrent. [6]

Physiological effects of electricity

Electrical shocks on humans can lead to permanent disabilities or death. Size, frequency and duration of the electrical current affect the damage. [8] The effects from electric shock can be: stopping the heart beating properly, preventing the person from breathing, causing muscle spasms. The skin features also affect the consequences of electric shock. [9]

Electronics and communications

Electronic products safety standards

The manufacturers of electronic tools must take into account several standard for electronic safety to protect the health of humans and animals.

Communication and high frequency safety standards

Few standard were introduced for the harmful impact from high frequency.
