A 69-year-old man has died while working as a bulldozer spotter cutting fire breaks for the Department of Environment, Land, Water and Planning at Gelantipy in Gippsland on Saturday.

It's believed the man lost control of his four-wheel-drive utility while driving down a steep embankment and was thrown from his vehicle when it rolled, suffering fatal injuries.

WorkSafe is also investigating the death of a 37-year-old man who suffered an electric shock and fell at a St Leonards property last Monday.

It's believed the man was standing on the top deck of scaffolding at a home being renovated when he came into contact with overhead power lines.

He suffered serious injuries and died in hospital on Saturday.

A 73-year-old Mulgrave man has also died in hospital, after he was crushed between a car door and an automatic car wash machine in Melbourne’s east last Monday.

It's believed the man was attempting to get back into his vehicle after re-entering the car wash access code, when the wash cycle started and he was pinned by the car door.

Worksafe is investigating all three incidents.

The fatalities bring the number of workplace deaths this year to 23, the same number as this time last year.
