Читать книгу One Hundred Steps: A Practical Guide to the 100 Steps That Can Make Your Workplace Safer - Darren Inc. Kay - Страница 7

This is a quick question, that requires very prompt response should the answer be ‘no’. A Residual Current Device is a very basic and very essential electrical safety component that should be in every workplace by law.

The NSW law states that: “An employer must ensure that, in relation to each electrical outlet socket at the employer’s place of work, the circuit is protected by a residual current device”; Occupational Health and Safety Amendment (Residual Current Devices) Regulation 2011. See: http://www.legislation.nsw.gov.au/sessionalview/sessional/sr/2011-73.pdf

An RCD works by comparing the current entering a circuit with that leaving a circuit – they should always be the same. If they are not, then some energy is going to earth. As this could be via a person, the RCD trips the power off. Several people die each year, who would not have done, had these simple devices been installed.

What to do right now:

Check your RCD by looking at the electrical switchboard. If you’re not sure, call an electrician to check, and fit one if necessary. Should cost $500 to $900.
