Unsafe work is work that involves an "imminent danger". An imminent danger can be
a danger that's not normal for that type of work, or
- a danger under which a worker in that type of work would not normally do the work.
- Workers must refuse to perform any job they believe would put them or their fellow workers in imminent danger.
- An example might be a situation where a worker is asked to enter or work in a trench that is more than 1.5 metres (5 feet) deep and not protected by either shoring or cutbacks. This situation poses an imminent danger.
