Hazard reduction burning kills

Particle matter pollution (PM2.5 & PM10) from 'unavoidable' burning is killing and hospitalising people every year. All beings that breathe are affected but those who are vulnerable, such as children, the elderly and sick people are more affected. Not only do they kill people who are already not in perfect adult health but they also cause illnesses including coughs, asthma and other lung conditions. They may also trigger heart attacks.

"Particles smaller than 10 micrometres (µm) in diameter (PM10) are consistently associated with increased mortality and hospital admissions for people with both heart and lung disease."

"Because of their smaller size, these particles can be inhaled more deeply into the lungs where the irritation can cause coughs, asthma and other lung conditions. Some are small enough to pass into the bloodstream through the finest blood vessels of the lungs where they can trigger heart attacks in people with existing lung or heart conditions and impact more severely on children and the elderly."
Harmful ozone causing further respiratory damage is also promoted by burning. "Hazard reduction burns are potentially significant sources of ozone precursors".

"Emissions from human activities are sufficient to cause regular exceedances of the AAQ NEPM standards."

When compared, it would appear that hazard reduction burning is more dangerous to human life than bushfires are, but that bushfires are more hazardous to property. Especially heap fires which are not 'unavoidable' could immediately be stopped to protect the air quality in rural areas. But perhaps hazard reduction burning might also be minimised to save lives with property as collateral.
