EFFECTIVENESS OF THE “A1-PD” DEVICE FOR STAFF WEARING PROTECTIVE CLOTHING WHILE PERFORMING COVID-19 PREVENTION DUTIES IN HOT WEATHER CONDITIONS

Abstract

The research and development of the A1-PD cooling device to support healthcare workers in combating the Covid-19 pandemic is of great significance, particularly in the harsh working conditions with protective suits during the summer of 2021. The A1-PD device utilizes the cooling principle of dry ice and a fan, helping to create a cool airflow inside the protective suit without affecting the user's activities. This device is easy to use, lightweight, and can operate continuously for at least 8 hours, enough for a full shift. Test results show that the A1-PD device helps lower the temperature inside the protective suit, with a temperature difference of -3.77°C after 60 minutes and -3.44°C after 120 minutes compared to the external environment. User satisfaction is very high, with 90% rating the device as effective throughout the shift. However, some users reported feeling restricted when bending down, indicating a need for improvement in future versions. The A1-PD device not only improves working conditions but also helps protect healthcare workers' health, ensuring they can complete their tasks in hot conditions without encountering serious health issues.
