Business users have encountered a significant degree of inertia on the part of Mapeley to undertake to their health and safety obligations, as demonstrated by the serving of UINs. In some extreme cases, Mapeley have only accepted their obligations hours before the attendance of the Health and Safety Executive. In fact their whole approach to meeting their legal health and safety obligations could be categorized as reactive rather than pro-active; at one site which encountered a lighting failure Mapeley's solution was to erect a fairy light style arrangement of bulbs suspended across the ceiling. There are also ongoing problems related to the removal of asbestos throughout the HMRC estate.
