In the scorching heat of Northern Australia, where the sun beats down with relentless intensity, the importance of managing ambient water temperatures in safety showers cannot be overstated. For workers facing the sweltering conditions of this region, safety showers are not just a regulatory compliance issue but a crucial aspect of their health and safety.
But why is this so critical? Imagine an employee, with a chemical splash to the eye, rushing to a safety shower for relief, only to be scalded by water that's been heated in the pipes by the baking sun. The very solution intended to offer safety becomes a risk itself. Not only does this scenario compound the emergency response but it breaches the Australian Standard AS4775, which mandates that emergency equipment delivers ‘tepid’ water, specifically between 16°C and 38°C, to avoid the risk of scalding during treatment.
Here are practical steps to ensure that safety showers provide not just compliance, but genuine safety:
-
Location and Shade Considerations: When installing a unit outdoors, give precedence to shaded areas or leverage the shadow cast by nearby buildings or trees. This natural cover can significantly reduce the heating effect of direct sunlight on the unit.
-
Protect Exposed Pipework: If a safety shower must be located in the sun, ensure that water pipes are not left above ground. Exposed pipes can act as thermal conductors, causing water temperatures to rise to dangerous levels.
-
Scald Protection Valves: Also known as Thermal Relief Valves, these devices are engineered to release water from the system when it reaches excessive temperatures (Fully Open at 40.6'C). This not only prevents overheating but also ensures the water temperature is within the safe range of AS4775. Click here to view a tech data sheet on our Safety Shower Scald Protection Valves.
-
Thermal Insulation: Thermal Insulation for Safety Showers is another line of defense against thermal heating of components that must be exposed to sunlight. This material acts as a barrier, reflecting the sun's rays and keeping the internal temperature regulated. While effective, insulation should be used in conjunction with Scald Protection Valves for optimal safety.
