Dear Diary

• Ear infection over, life so much nicer
• Comforting emails notwithstanding, uni textbook has not arrived on schedule - Bad fishpond, bad. Also your email subscription page’s unnerving tendency to spontaneously re-tick boxes does not endear you. I wonder if your choice of ‘games’ and then ‘music’ was random
• Took lilysea to IKEA to stalk beds for both of us, was exhausting, bought a nest single bed, I get the pleasure of assembling it tonight
• Father's Day unexpectedly traumatic but in a good way, am contemplating counselling, do not wish to be triggered by good things
• Work ‘do’ involving pub food, robot soccer battles and bowling. I can’t bowl, like I can’t ever remember which is my dominant hand when I’m playing – they are both that terrible, it was a surprisingly fun evening

Occupational Health and Safety Statistics Report - Frequency Rate

Things wot I learned today: you can get a report that measures the frequency of (reportable) injuries per year per total person hours worked.

• Frequency = (reportable injuries /people hours) * 1,000,000

The 1,000,000 is to get the numbers to look like integers rather than things like 0.000006 which is hard to relate to.

I ran it for Industry versus Gender because I love me a good chart. I'm unsurprised to see Transport, Manufacturing, Construction and Ag. as the main offenders and want to know what "Personal and Other Services" are.



I tried to find comparable US data and the closest I can find is a PDF of what appears to be similar type calcs except it turns out you have to multiply the US frequency by 5.

• Frequency (US) = (reportable injuries / people hours) * 200,000

Huh, no two systems ever use the same baseline :(
