Posted By John Beadle Is there any guidance published regarding working near mobile phone/radio transmitter masts. Scenario: - many high-rise buildings now have a cluster of aerials near where work on other equipment (e.g. air conditioning) may have to take place. Your assistance in this matter will be appreciated. Regards John

Posted By colin get in contact with OFCOM, its their area.

Posted By David A Jones John, there is plenty of guidance available within the industry on these matters, however, the exclusion zone around each antennae could be different depending on the design and power output of the unit. The operators provide details of these exclusion zones to landlords as part of a 'landlord pack'. Responsibility firmly sits with the landlord to undertake a risk assessmnet of the activities he allows to take place on his roof - the HSE are in the process of drafting an internal guidance document that says precisely that. Therefore, your first port of call should be the landlord - asking for a copy of his rooftop risk assessment and in particular the information you are after i.e. RF exclusion zones. It is worth noting that in most cases the exclusion zone is very small (<0.5 m) in areas that would be accessible.

Posted By George Wedgwood You could have a look at the Telecoms SG web page and one of their Newsletters at http://www.iosh.co.uk/fi...s%20News%2010%5F04%2Epdf Contacting one of the Committee may be helpful for further explanation and risk assessment advice. Regards, George
