In this chapter, the authors consider six aspects of how to prepare for every site visit the people intend to undertake – whether to an unoccupied or occupied site – to ensure they are adequately equipped to undertake their visit safely: Site surveys and research, Plan of work, Site occupation and vacant sites, Clothing, equipment and personal protective equipment, Weather conditions and First aid. All employers have a duty to provide adequate asbestos awareness training to anybody visiting site. If the site owner's asbestos management survey has identified the presence of asbestos on site, ensure that a refurbishment/demolition survey is completed prior to any destructive opening-up work. Bear in mind that peak flows in streams and rivers may not occur until several hours and possibly days after heavy rain, and can cause unexpected flooding during otherwise benign weather conditions. There are two types of survey for asbestos: a management survey and a refurbishment/demolition survey.
