Time to Breathe calls on employers, policy-makers and regulators to start taking seriously the risk of ambient air pollution to the health of outdoor workers. 

If you care about the health of outdoor workers, please do get involved and support the campaign.  

Our Time to Breathe white paperexplores the evidence and assesses what actions the Government, employers and stakeholders should take to minimise the health impacts of pollution on outdoor workers. 

The campaign is providing visual materials to encourage people to stop, think and act to reduce air pollution exposure. Please share these free images. Together we can all cut-through the inertia that is putting lives at risk. 
Please note, the Canairy app, which we developed with Imperial College London, has now ended. If you have downloaded the app, it will no longer collect or monitor your exposure to air pollution. So we suggest you now uninstall the app from your device.

Outdoor workers in their thousands include street cleaners, refuse workers, traffic police, cycle couriers, construction workers, maintenance workers, newspaper sellers, gardeners, teachers or security guards working on busy roads. As a group, they help us cross the road, guard our children, fill potholes, deliver our food and ensure we have clean water, electricity, WiFi or cycle lanes. 

Time to Breathe is calling for: 

  • Employers to take ambient air pollution seriously and protect their outdoor workers from the worst levels of toxic air 
  • Improvements to pollution monitoring across the UK so that all regions have the same accuracy as London for emissions data 
  • The UK to adopt World Health Organisation (WHO) exposure limits for the main pollutants of nitrogen dioxide, particulate matter and ozone 
  • Everyone to reduce their pollution footprint. Let’s use clean energy, cycle and walk more to reduce emissions. 
  • Workers and trades unions to raise this issue with their employers and show the evidence about the risks. See Unite’s Diesel Exhaust Emissions Register

"BOHS are pleased to support the Time to Breathe campaign. Our Breathe Freely campaign focuses on the threat to workers health from exposures caused by their work, but it’s easy to forget that many workers are exposed to serious risk simply from the environment they work in. Outdoor workers are at particular risk of suffering health problems due to pollution in the wider environment. This campaign can help employers do something about that."
