Answer passage (source: UK):
page_title: Guidance Coronavirus (COVID-19): safer transport guidance for operators
section_headers: Ventilation
section_content: Organisations should consider how to increase ventilation and air flow. Where
possible, transport operators and businesses should ensure that a fresh air
supply is consistently flowing through vehicles, carriages, transport hubs and
office buildings.
To achieve this, organisations could consider:

Air conditioning. Most air conditioning systems do not need adjustment, however where systems serve multiple buildings or you are unsure, advice could be sought from HVAC engineers.
Fresh ventilation systems can operate as normal, but recirculating air systems may require adjustments to increase fresh air flow.
High-Efficiency Particulate Air (HEPA) filtration.
Opening doors and windows where possible and safe to do so.

section_content: Organisations should ensure that any site or location that has been closed or
kept partially open during the coronavirus outbreak is assessed and
appropriate steps taken to prepare for restart or ongoing operation.
Organisations could consider:

Conducting a working environment assessment for all sites that have been closed, before restarting work.
Carrying out cleaning procedures, providing hand sanitiser, adjusting ventilation before restarting work.
Using Heating, Ventilation and Air Conditioning (HVAC) systems and/or opening windows and doors to encourage ventilation, where possible and safe to do so.

Hygiene – handwashing, sanitation facilities, toilets and showers
section_content: To help workers and passengers maintain good hygiene, organisations could
consider:

Use signs and messages to build awareness of good handwashing technique and other hygiene behaviours for example around coughing and sneezing.
Providing paper towels in hand washing facilities.
Sufficient provision of hand sanitiser onsite in addition to washrooms, and for those working away from hand washing facilities.
Configuration of toilet and shower facilities to ensure they are kept clean, with social distancing where possible and with best practice handwashing followed between each use.
Enhanced cleaning for facilities that are heavily used.
Keeping showers and changing rooms closed until clear use and cleaning guidance is set.
Minimising use of portable toilets.
Providing more waste facilities and more frequent rubbish collection and disposal.


Reviewer feedback on this answer:
It doesn't even mention ventilation systems.
This doesn't answer the question, it talks about maintaining good hygiene.
