A mum who lost her tradesman son in a workplace accident has vowed to help the grieving family of the Sydney worker who died when he was crushed by a 300kg pane of glass.

The 49-year-old man was killed in a workplace accident at a residential property in Dural, in Sydney’s north-west on Monday. 

Emergency services rushed to the home on Valencia Street just after 11am that day, but the man could not be revived despite frantic efforts to save him. 

NSW Police have now launched an investigation into the circumstances surrounding the incident and a report will be prepared for the coroner.

Patrizia Cassaniti, whose 18-year-old son Christopher died in 2019 on a construction site after the scaffolding beside him collapsed, said she was horrified to hear of the tragedy.

‘It was horrible… I am a local as I live in Castle Hill. So everyone that saw the news sent it to me,’ Ms Cassaniti told the Daily Mail.

Ms Cassaniti, who launched the Touched by Christopher Foundation in her son’s honour, has now asked for the family and friends of the Dural man to get in contact with her, as she’d like to offer them financial support in the weeks and months ahead.

The foundation provides families who have lost a loved one in a workplace incident with three months’ worth of groceries, $1,500 towards outstanding bills and $5,000 to help cover any mortgage or rent payments.

‘Touched by Christopher has been raising money for the last seven years to help families… because unfortunately there is no government scheme that helps families from a workplace death, other than the death benefit, which is not released for at least nine to 12 months,’ Ms Cassaniti said.

‘In that time we are the only help they have access to. 

‘The charity is run completely by volunteers and we have minimal cost to run the website which we try to have companies to sponsor us for.’

Ms Cassaniti said the foundation has been able to support 42 families across NSW so far after raising around $430,000.

She would love to be able to support the man’s family to access that support too.

‘No one should go to work and never come home,’ she said.

‘Every death is heart-wrenching as I know exactly what the families are going through… I relive my son’s death every day but there is nothing I can do to change what happened; all I can do is to keep his legacy.

‘He always helped others and if we can help families after such tragedies, we honour him.’

Ms Cassaniti has asked for anyone who knows the man’s family to contact her at admin@touchedbychristopher.org.au 

She has also asked for any businesses or individuals who’d like to support the cause to register for Australia’s Biggest BBQ that runs throughout April.
