What is the required diameter for hoses in handlines inside class A chambers?

¾ inch
½ inch
1 inch
1½ inch

The correct answer is: ½ inch

The correct choice is based on industry standards and safety regulations governing hyperbaric facilities. In Class A hyperbaric chambers, the use of hoses in handlines is designed to ensure adequate flow, manage pressure, and support emergency protocols. Utilizing a ½ inch diameter for handline hoses strikes an optimal balance between flexibility and sufficient delivery of oxygen or other gases for patient needs during treatment. This size is widely accepted because it allows for a manageable flow rate while maintaining the structural integrity of the hoses under increased pressure within hyperbaric environments. The larger diameters, such as ¾ inch or greater, are generally unnecessary for the intended functions of handlines, which could complicate handling or lead to difficulties in controlling the flow rate precisely. Conversely, a ½ inch diameter offers practicality in the chamber setup, contributing to both efficiency in operation and adherence to safety protocols.
