Man dies, three hospitalised by chemical

Authorities say it's still unknown whether a garden herbicide is responsible for a
Sydney man's death or he simply suffered a heart attack.
The 56-year-old was spraying his market garden on Wallgrove Road in Horsley Park
when he collapsed soon after 8am (AEST) on Wednesday.
However, police have described the spray as "a normal garden herbicide, something
stronger than Roundup".
Twenty-one people, including family members, neighbours and paramedics who tried to
revive the man, underwent decontamination as a precaution.
Three people who were first on the scene were taken to hospital for decontamination
and observation, but have now been released.
Others, including seven paramedics, were decontaminated at the scene.
"I understand that there were some 21 (people) that required decontamination after
assisting the deceased," Police Superintendent Peter Lennon told reporters.
"It is unsure whether or not he died of natural causes.
"It might have been a heart attack, or from the use of the herbicide."
An autopsy will be carried out to determine the cause of his death, Supt Lennon said.
Wallgrove Road was closed in both directions as a precaution after the man's death.
But the busy arterial road was reopened just after lunchtime when police and NSW
Fire Brigades determined the chemical wasn't in the air and posed no public danger.
"Initially (it was thought) the herbicide might be something more serious that was
actually in the air," Supt Lennon said.
"We have now assessed the fact that it was just something (that is) on the ground."
