(1) Subject to paragraph (5), the employer must make a suitable and sufficient assessment of the risks to workers arising from their exposure to electromagnetic fields. (2) The risk assessment must include consideration of, where relevant— (a) the ALs and ELVs; (b) the frequency range, level, duration and type of exposure, including its distribution over the worker’s body and the workplace; (c) direct biophysical effects; (d) replacement equipment designed to reduce the level of exposure; (e) information obtained from any health surveillance or medical examinations provided under regulation 20; (f) information provided by the manufacturer or distributor of equipment; (g) multiple sources of exposure; (h) simultaneous exposure to multiple frequency fields; (i) indirect effects; (j) any effects on workers at particular risk; and (k) other health and safety related information. (3) The risks referred to in paragraph (1) do not include the risk of effects— (a) caused by contact with live conductors; (b) caused by multiple and separate instances of exposure; or (c) which continue to develop when exposure has ceased. (4) The employer must review the assessment when— (a) there is reason to suspect it is no longer valid, or (b) there has been a significant change in the matters to which it relates, and make such changes to it as are necessary to ensure it remains suitable and sufficient. (5) Where an employer has made an assessment before the date on which these Regulations come into force, which assessment would have complied with the requirements of this regulation, that employer is to be treated, on and after that date, as having complied with paragraph (1).
