I think there may be some confusion here.
I imagine they are suggesting that when you put your mouth onto a mannequin's mouth and inflate the artificial lungs to make the chest rise, there is a confined space within the mannequin that cannot be effectively cleaned between trainees. They have removeable/cleanable mouths, but nothing internal can be cleaned. When the 'lungs' deflate, you are at risk of inhaling whatever was breathed into the dummy by the user before you.
Our first aid trainers haven't changed their mannequin, but they do ask you not to breathe into the mannequin post covid.

We use 10km and 20km excess of speed limit as 2 different triggers.
Discretion is 5 seconds entering a lower speed limit. Reports are done monthly - one month = 1 record, records kept for 6 months.
10km over - reported to line manager who meets with staff member. 3 records is a referral to HR.
20km over - report to line manager and general manager, 2 records is referred to HR.
140km/hr is gross misconduct (we've never had this, but managers wanted a top number in).
We've been doing this for 12 months now and it has significantly changed driver behaviour.

Having been a council enforcement officer for Pool Fencing in a past life, there is zero provision for exemption from the Act. So maybe the issue is not the person with the clipboard but legislation that takes no account of the context of risk.
