Departmental Working Alone PolicyDepartmental Working Alone Policy
workplaces require staff to work alone and therefore requires that a plan is in place that is agreeable to both the employer and employee. The plan should be based on a realistic risk assessment of the hazards under the
i t d i l d itt circumstances and include a written emergency response plan
Review your Department’s “Working Alone Policy” – The y p g yUzonna Policy that includes:
Mandatory buddy system where staff and students must work in pairs.
Supervisor notification before starting work after hours.
Restrictions to certain types of work.
