Businesses in the North West have been reminded to make sure contingency plans are in place to protect workers during the cyclone season.
The season officially begins on November 1, and WorkSafe WA commissioner Lex McCulloch says it is crucial that everyone working at sea and on land knows what to do when there is a cyclone in the area.
"Under workplace safety and health laws, employers must have adequate plans in place and provide adequate training to protect workers in the event of a cyclone," Mr McCulloch said.
The Bureau of Meteorology expects two tropical cyclones on the North West coast this season and predicts one of them will be severe.
Mr McCulloch said there were workplaces in the northwest where employees from several companies worked on the same site, so it was especially important that emergency evacuation plans were coordinated.
"Employers should not leave anything to chance when a cyclone is threatening and must make sure safe work practices are in place well before a cyclone is in their vicinity," he said.
