Which type of connections are not required to be accessible when attached to fireproofed structural metal?

• A. Standard screw connections
• B. Welded connections
• C. Exothermic or irreversible compression connections
• D. Temporary connections

Answer: (C)

The correct choice highlights that exothermic or irreversible compression connections are not required to be accessible when they are attached to fireproofed structural metal. This is primarily because these types of connections are designed to create a permanent bond and do not typically need to be inspected or maintained in the same way that other types of connections might require. Exothermic connections, for instance, are created through a chemical reaction that fuses metals together at a molecular level, resulting in a joint that is inherently strong and designed to last for the life of the structure. Since these connections are permanent, they do not necessitate regular access for inspection or maintenance, particularly when the connecting elements are fireproofed, as the fireproofing can also mean less exposure to environmental damages or wear. In contrast, other types of connections, such as standard screw connections and welded connections, may be subject to wear and require periodic inspection to ensure structural integrity and safety. Temporary connections, by nature, are designed for short-term use and therefore need to be accessible for adjustments or removals, making them part of safety and maintenance protocols. This rationale clarifies why exothermic or irreversible compression connections differ fundamentally in their accessibility requirements compared to other connection types.
