Construction workers face rising heat risks as summer temperatures soar
As thousands of construction workers return to sites while many New Zealanders enjoy their summer break, the heat intensifies. Safety experts warn that heat stress can impair judgment and heighten the risk of serious injury. However, the construction industry's workplace safety training body emphasizes that heat management is often overlooked, treated as a 'nice-to-have' rather than a critical component of site safety.
According to Site Safe chief executive Brett Murray, there are no specific temperature thresholds in New Zealand or Australian legislation mandating work cessation. This places the responsibility on companies to effectively manage heat risks.
Construction Health and Safety New Zealand highlights that the risk of injury escalates with each degree of heat increase. Chris Alderson, the chief executive, underscores that even minor temperature fluctuations can impact workers' safety. He notes that perspiration and sweaty hands can lead to tool-related accidents.
Despite progress in sun protection and UV risk awareness, the industry faces new challenges. Murray acknowledges the industry's collaboration with the Cancer Society to raise UV danger awareness but points out the need for lightweight clothing to prevent excessive sweating.
Both organizations advocate for enhanced company and site manager accountability in managing heat risks. This includes providing breathable, lightweight clothing, scheduling regular rest breaks, and ensuring access to shade and water.
Alderson emphasizes that effective heat management is cost-effective but should be treated as essential rather than optional. However, industry leaders note that dedicated shade, water, and rest areas are not universally standard practices across the country.
Water availability on construction sites is a recurring issue, especially in remote or road-based locations, according to Alderson.
At a Wellington construction site, workers prioritized heat safety. Each morning, they received weather briefings and were reminded of hydration and sun protection. This proactive approach aimed to mitigate heat-related risks effectively.
