The client department or service, ie the department responsible for appointing the contractor, is responsible for ensuring that the contractor is competent and will not put any School staff, students or visitors at risk. They must obtain method statements and risk assessments from the contractor in order to assess their ability to undertake work safely.

Contractors must be provided with information on any matter that may affect their health and safety while working in the School, including fire arrangements and arrangements for responding to situations of serious and imminent danger such as gas leaks etc.

Client departments must consult the Estates Division before appointing any contractor. Contractors may need to obtain a 'permit to work' before entering some locations in the School.

Client departments must also ensure that there are adequate arrangements for monitoring the safety performance of contractors while the work is in progress. There should be arrangements in place for taking action where the contractors fail to perform to agreed standards.
