In an environment where hazardous substances are part of the overall setup, such as chemical laboratories or loading docks, emergency or safety showers must be provided. After all, it is vital that employees and handlers be protected against chemical exposure. In Australia, it is important for emergency showers to meet the safety shower Australian standard, which underscores the importance of a safety shower test kit. Failure to comply not only endangers employees, but the business is well.
Understanding the Australian Standard AS 4775-2007
This specifies the minimum use and performance requirements for an emergency eyewash and shower equipment.
- Water temperature must be maintained anywhere between 15.6°C and 37.8°C to prevent further damage to skin and eyes.
- Safety showers that are fully insulated must be used when ambient temperatures tend to climb above 40°C or in areas of extreme temperatures.
- When necessary, a chiller unit or heating unit is fitted to the emergency shower to ensure water temperature is compliant to the safety shower Australian standard.
- For mains water supply that is unreliable or not available, a water tank must be installed nearby. It should have enough flushing liquid for a minimum of 15 minutes.
- Flushing fluid is any medically acceptable solutions that can wash off chemicals without causing further damage. This may include preserved water, potable water, or preserved buffered saline solution.
What makes a reliable safety shower?
Fully compliant with the safety shower Australian standard
Apart from the minimum requirements listed above, the Australian Standards AS 4775-2007 also require that relevant test procedures are carried out to ensure that the equipment works as expected and intended. From the construction of the shower spray unit to the spray nozzle, every aspect of the equipment must be tested to ensure compliance.
Must have the right amount of flushing liquid
Flushing can vary between 5 and 60 minutes, depending on the chemical an individual is exposed to. Exposure to mild irritants or non-irritants, for example, requires flushing of 5 minutes. But when someone is exposed to calcium hydroxide, potassium, sodium, or other strong alkalis, a 60-minute flushing is critical. And when irritation persists, the flushing procedure would have to be repeated. This means access to flushing liquid is vital.
Fitted with the right fixtures
The valve is the heart of any high-quality safety shower, and the best kind should be purposely built for emergency showers, virtually unbreakable, and with a fully enclosed valve stop assembly, among others. The spray nozzle must meet the Australian standard spray profile, while the piping must have a low carbon content, which is suitable for highly corrosive environments, and stainless steel fittings.
