Travel, Working Overseas and Safety Accordion
There are some actions that you must take when planning to travel to help ensure that you have a safe and productive trip. Please allow enough time to complete the necessary pre-travel planning steps.  Complex trips abroad, working in remote areas or involving high risk activities, may take a number of weeks or months to organise adequately.  These pre-planning activities should be initiated sufficiently in advance of the trip. Refer to the Staff travel and expenses webpage for comprehensive guidance /staff-travel-and-expenses/planning-a-trip/overview/ Ensure you have familiarised yourself with the Off Site Working Policy on Safety's website.
The Expenses team are responsible for payment of all employee and non-employee (e.g. student, consultant) expense claims. All project expenditure must comply with funder terms and conditions and with the Expenses Policy.
Refer to the Off-site working webpage for advice on completing an assessment of the hazards associated with your activity and location, and to assist with identifying appropriate controls to reduce your risk of harm.
The  International Mobility Guidance on Overseas Working   provides an outline of the main areas you should consider and the process you should follow when submitting a request to work overseas.
