It is important to have procedures that encourage participation.
Risk assessment should focus on real risks, rather than on those that are trivial or the result of over-protectiveness. Exposure to real risks should be offset against the benefits of undertaking the visit.

It does not require the use of technical formulae and professional health and safety expertise should only be needed in the more complex or specialist cases.
