Police have warned firebugs they will be on high alert this week. MORE: Temperatures soar around nation SafeWork SA has called on workplaces to ensure they have appropriate measures in place to cope with this week's heat. Hot weather is a workplace hazard that needs to be considered when planning work activities," SafeWork SA executive director Bryan Russell said. Heat stress can afflict workers at outdoor locations such as construction sites, storage yards, tarmacs, roads and farms. It is also important to recognise that heat poses a risk in confined spaces. Temperatures in industrial sheds can exceed 50C, placing workers at risk. Working in a hot environment can impair workers' concentration and judgment, which heightens the chances of other harmful incidents occurring. Heat stress symptoms include: headaches; fatigue; dizziness or fainting; increased sweating; mood changes such as irritability or confusion, an upset stomach or vomiting. Working on through the symptoms of heat stress, can lead to serious illness and in extreme cases, death," Mr Russell said. Employers are advised to do any physically demanding work at cooler times of the day, rotate workers out of the sun, and provide shade, hydration, UV protection and ventilation. The Local Government Association has encouraged the public to head to their local library, shopping centre, community centre or pool to beat the heat. "It is imperative that we look after and monitor the more vulnerable in our communities in extreme heat conditions," LGA acting president Mayor Lorraine Rosenberg said. Children, the frail, the elderly and unwell members in our communities will need extra vigilance as the hot weather comes in. If you have an elderly, frail or vulnerable neighbour, or family member, it is important to check that they are coping in the hot weather. Those who do not have domestic air-conditioning, or are anxious not to use home cooling devices because of high electricity prices, will be welcomed at local libraries and community centres.
