This video is interesting https://www.zeroharm.org.nz/resources/risk/fatigue-risk-management/ It nicelys outline the dangers of relying on a single limit as a fatigue management approach

Here's the CAA's example: https://www.caa.govt.nz/assets/legacy/Advisory_Circulars/AC119_2.pdf
Single pilot, VFR operations are the closest to driving.
Ag industry would be an interesting one to work on, as you have you may be physically fatigued but not mentally, or vice-versa.

Here's one from a typical green field factory contruction site:

Work Hours
In accordance with the Fatigue management policy the hours of work should follow:
• 12 hour day’s
• No more than 70 hours per week
• No more than 17 days continuous in any 21 days
• [Provide safe transport to and from accommodation]

Extended work hours management:
• No more than 15 hours in any 24 hours
• Only 1 day longer than 14 hours in any 7 day period
• 10 hours’ time away from site after working 14 hours or longer
• Provide safe transport to accommodation for those working 14 hours or longer

Don't forget to cover travel to & from 'work'. there's a lot of evidence on vehicle accidents caused by fatigue due to work.

Hi Linda, Kiwirail and the RMTU (Union) have done a lot of work on fatigue. Suggest you get in touch with Karen Fletcher at RMTU. WorksafeReps has just started a new course on managing and preventing fatigue (1 day course for shift workers and managers).

Hi Linda
NZTA has some good information:

HSE Managing Shift Work Hours has useful information also.

thanks appreciate that!

thanks!

Wow, so they expect people to be able to work for 17 10-hour days in a row without suffering from fatigue?
Having worked something similar, at about 14 days you hit a low point. We were working 28 days on, 28 days off, and away from home so the dynamic was different - you were removed from home pressures, which alleviated it somewhat, but still that 14-day low was fairly common.

Yes, Standard site contracts. believe me that project managers choose to ignore these rules when it suits.
