"What temperature can we knock off at?"
Every summer, same question. And the answer is not what most blokes think.
There is no legal stop work temperature in NSW. The WHS Regulation does not set one, because 40 degrees laying pavers is a different risk to 40 degrees in a roof space or in full harness on a metal roof. What the law asks is whether you assessed the risk and did something reasonable about it.
That is one of about ten things that change on your site in a hot summer, and the Bureau has a strong El Nino building right now that is tracking toward the warmest on record.
We have written up the lot. Concrete that goes off before you can finish it. Grinding and welding on a total fire ban day and the exemption most people do not know exists. Dry clay cracking houses eighteen months after handover. And whether your contract even lets you claim a day lost to heat.
We already copped a total fire ban across Greater Sydney last week. It is still winter.
