WHS-011-FRM
This form is a record of the fatigue assessment for a person under AquawestFatigue Management Procedure. The privacy and confidentially of that person will be maintained with respect to the information gained as a result of the fatigue assessment.
If any person has difficulty with completing assessment seek advice from your supervisor.

(Z) Add one point per hour awake greater than sleep in step 2
SCORE (add total points)
For example, using a point system may assist in determining what course of action an individual and/or organisation may take. A simple point system could be something like the following:
Example – Low Fatigue
If I have slept 6 hours in the prior 24 hours, and 10 hours in the prior 48 hours and have been awake for 2 hours I have
X=6 (sleep in prior 24 hours); Y=10 (sleep in prior 48 hours) and Z=2 (hours awake)
Points System
Step 1 + Step 2 + Step 3 = Fatigue Risk Score
0 + 4 + 0 = 4
Example – Higher Fatigue
If I have slept 3 hours in the last 24 hours, and 6 hours in the prior 48 hours and have been awake for 10 hours I have;
X=3 (sleep in prior 24 hours); Y=6 (sleep in prior 48 hours) and Z=10 (hours awake)
Points System
Step 1 + Step 2 + Step 3 = Fatigue Risk Score
8 + 8 + 4 = 20
FEELING / SCORE / ACTIONFully Alert / Less than 1 / No Action
Okay / 1-4 / Personal Monitoring
Moderately Tired / 5-8 / Assess Risk for activity being undertaken. Advise Supervisor
Completely Exhausted / 9+ / Advise Site Supervisor. DO NOT Commence work.

Use these signs and symptoms for Fatigue when completing a Fatigue Assessment.
Appendix 2 – Prior Sleep Wake Model
This tool is used for qualifying a person’s fatigue risk level/s based on the amount of sleepobtained in the prior 24 and 48 hour period.
The basis of the model is minimum sleep of:
• 5 hours in the previous 24 hour period and
• 12 hours in the previous 48 hour period.

/ Sleep / Sleep / WorkX

Z
X = Sleep in prior 24 hrs
Y = Sleep in prior 48 hrs
Z = Time Awake
As prior sleep decreases and prior wake increases the likelihood of fatigue also increases.
In general; X should be greater than threshold of 5 hours
Y should be greater than threshold of 12 hours
Z should be less than Y
