After a teenage apprentice almost died in his first week on the job on a construction site during a recent heatwave, new extreme-weather codes for private building sites could come into place this year.
The CFMEU SA is pushing for the codes, calling for building and business groups to help develop the extreme hot-weather codes.
A few weeks ago 17 year old Travis Mellor collapsed on a building site in Magill. He was rushed to hospital and narrowly avoided death.
The extreme heat guidelines are crucial for private building jobs to keep workers safe. The unions want workers to down tools when temperatures exceed 37 degrees.
