Are exothermic or irreversible compression connections required to be accessible?

In this context, the correct response is that exothermic or irreversible compression connections are not required to be accessible. This means that these types of connections can be made in locations that do not allow for easy access. This can be significant in systems where space constraints make accessibility difficult, as long as the connection is properly made and does not pose a safety risk.

Accessibility requirements often apply to certain types of components or connections to ensure maintenance and inspections can be performed easily. However, for exothermic and irreversible compression types, the absence of such requirements indicates that once properly installed, they are expected to function without the need for routine access. This can help in simplifying installations and reducing costs associated with designing systems that would otherwise need to accommodate easy access to every component.
