I was quite impressed by how well the ventilation was working given the age of the building and the amount of people. Of course things can always be improved, but everyone worked hard to get there.

They have. It's not a simple feast, firstly sourcing high capacity filters, then installing them safely in strategic places and lastly at close range when people get together they won't do much to stop transmission.

Not quite, Babb is derived from bappig which means sticky in the most unpleasant way. Dog poop to your shoe sticky level. Sack alone is a mild swear, a bit like a mild form of asshole. So it's a bit like a very unpleasant person sticking to you and getting on your nerves?

In Hesse 'Babbsack', in the North 'Torfkopp'. Not sure about the deep south but there'll be plenty to pick from. For advanced nastiness check the Austrian vocabulary as they really excel at this

Seems to me like you were wrong along, and worst still, you KNEW you were wrong yet you were blindly guided by the "science" of Comrade Jacinda. You need to be held accountable". Comment five reads: "You don't deserve a cent. From anyone. Our corrupt politicians stupidly gave you a public platform to spew your garbage. You lied to the country about covid, deaths, cases, lockdowns, masks, social distancing and safe and effective vaccines. You lied, people died. And you gaslit those good people bravely standing up and telling the truth. You and your woke lying mates created the fear and confusion amongst our people. You should be tried, charged and jailed for the damage you have done". Comment six reads: "Hope you're absolutely bankrupt evil pink-haired lying witch". Comment seven reads: "how much money did you make from all those media appearances during covid?? Surely enough to cover your legal fees????". Comment eight reads: "You're a fat pinked haired hack". The final comment reads: "So are school boys still able to ejaculate after getting covid (thinking face emoji) you said they would not be able to in the leaflets you distributed to schools?? you should be the one being sued for your bullshit information during Covid, you made millions of public money telling lies you sick twat".

I thought everyone could use some good news! My conservation friends' nesting box survived Wellington's wild storm perfectly and a Ruru (tiny owl) sheltered in it. Then one started making a nest! There's a camera inside now, too. The feeds aren't public but here's how they're doing.

@thomasnash.bsky.social you are chairing the transport committee and were present during my presentation. It's extremely disappointing to see so much inaction and authorities passing the bucket instead of taking responsibilities. Other municipalities can provide good ventilation on public transport.

And worse: GW is currently procuring new trains, and there are no sufficient requirements for ventilation for the new trains. Instead they just require UIC 553 which targets 5000ppm CO2.
100
Oliver Seiler @oseiler.bsky.social · 04/07/2025
So it looks like everyone is passing the bucket and nobody is taking responsibility. I'm not a lawyer but from my understanding GW has the ultimate responsibility for H&S, but as far as I an tell there's no tangible action - not even data collection to know the extent of the issue.
100
Oliver Seiler @oseiler.bsky.social · 04/07/2025
Besides that, there are plenty of studies that all demonstrate that the observed CO2 concentrations are not only inacceptable for public health but impacting the driver's cognitive capacities similar to a drunk driver. How is that acceptable?

Oliver Seiler @oseiler.bsky.social · 04/07/2025
I received a response from Metlink, which basically explained that drivers cannot control the aircon or even open windows any longer, and a number of excuses why without national standards they won't pursue any engineering solutions because it's "too hard".
100
Oliver Seiler @oseiler.bsky.social · 04/07/2025
I have presented this to GW transport committee in Feb/24 and suggested some easy and cost effective work arounds while engineering solutions are being developed
Slide: Metlink and GW have been aware of poor ventilation on public transport for a long time
- Metlink commissioned study showing buses regularly exceeded 800ppm indicating inadequate ventilation, October 2022
- “Poor ventilation in public transport settings in Aotearoa NZ: New data for buses and trains”, July 2023, found that in buses and trains with more than 50% of seats occupied, ventilation was typically poor, with CO2 levels above 800 ppm 94% and 77% of the time, respectively.
- “On-board bus air quality - Impact of changing ventilation on a double-decker bus” NIWA study from July 2023 requested by Metlink 
- “the results suggest that existing ventilation may be insufficient at times of high passenger volumes”, MoH advice requested by Metlink in May 2023
- In a published OIA response Metlink stated that it "believes there is significant further testing that needs to be undertaken and is advocating that Waka Kotahi NZ Transport Agency and the Ministry of Health conduct more robust testing to enable national air quality standards for public transport buses to be determined.“
- “investigation into engineering solutions for improving air quality in public buses started in December 2022” - OIA response
- Driver shortages due to high levels of sickness regularly being quoted by Metlink as reason for the high levels of cancelled or delayed services
- Educate drivers to keep windows open, and open all doors at every stop, especially now during favourable weather
- Remind drivers to not use recirculation but always let enough fresh air in
- Put up information sheets for drivers and passengers to remind them of the importance of ventilation
- Install publicly accessible CO2 monitors to provide immediate feedback to the driver, and to make passengers aware of air quality, as well as to identify harder to ventilate routes/vehicles with regular higher levels
- Reward drivers who consistently have well ventilated buses
- Perform spot checks, especially during peak times

Including that 'PCBUs “must minimise risks to health and safety, so far as is reasonably practicable, by taking one or more that is the most appropriate and effective taking into account the nature of the risk”' Yet, passengers are only left with the least effective 'last line of defence' (masks)
Slide: 4 layers of risk management, most to least effective:
- First try elimination: eliminate risks
- If elimination is not reasonably practicably: Substitute, Isolate, Apply engineering control measures
- If there is still risk: Apply administrative control measures
- If risk still remains - PPE is the last line of defence
100
Oliver Seiler @oseiler.bsky.social · 04/07/2025
MoH also recommend a target of <800ppm CO2 or 5ACh for procurement of new buses and reminded Metlink of the 'Hierarchy of control measures'.
110
Oliver Seiler @oseiler.bsky.social · 04/07/2025
Which isn't correct - NZ has regulations that apply - to drivers and passengers. Metlink has asked Ministry of Health for guidance and were given standards and exposure limits, told that these apply public transport, including to passengers.

Oliver Seiler @oseiler.bsky.social · 04/07/2025
Thanks for sharing your data. Sadly this isn't uncommon, or unknown by GW/Metlink. There have been a number of studies and investigations into this, but without any meaningful action (as as as I can tell). Instead Metlink and GW seem to be hiding behind a 'lack of national standards'.

I've also managed to pry the metal strip loose using long tweezers trough a smaller cut on both ends and remove it, which allows the plastic clip to be threaded in from the side and removes the need to sew close the long cut, but it's quite fiddly and easy to rip the thin top layer.
