Fire crews from across Christchurch city are battling a large blaze at the Bromley Waste Treatment Centre.

A Fire and Emergency spokesperson said the fire was initially reported at 3.07 pm.

Currently, there are eight appliances at the scene.

A Fire Command Unit has been set up on Pages Road to help coordinate the firefighters.

The fire is believed to have started on the roof on the No2 Trickling Filter before jumping across to the roof of the No1 Trickling Filter.

There were contractors working on the roof when the fire broke out. No one was injured and the site is being evacuated.

The roofs on both the trickling filters have collapsed.

Residents living down wind from the scene are encouraged to keep doors and windows closed.

People are also asked to please stay away from the area.

Police have blocked off surrounding roads.

Canterbury DHB’s Community and Public Health unit has issued a public health warning.

 “Air around this location is smoky and there is potential that people who are sensitive to smoke – such as those with heart or lung conditions, pregnant women, young children and the elderly ­– may experience symptoms including coughing, shortness of breath or eye, nose and throat irritation.”

 Canterbury Medical Officer of Health Dr Cheryl Brunton says exposure to smoke can worsen pre-existing health conditions such as asthma and heart disease.

“People affected by the smoke should close windows and doors and stay indoors.

FENZ is continuing to work to get the fire under control.

The Easterly wind is sending smoke in the direction of some of Christchurch’s eastern suburbs and central city areas. 

“Anyone experiencing health issues from the fire should contact their general practice team for advice, in the first instance,” Dr Brunton says. 

What to do when it’s smoky outside

If you see or smell smoke outside, you should stay inside if it’s safe to do so.

Remember to:

• Keep your windows and doors shut

• Switch your air conditioning to ‘recirculate’

• Air out your house when the smoke clears

• Look out for children, older people, and others at risk

• Keep pets inside with clean water and food. Keep pets’ bedding inside if possible.
