Which of the following can lead to safety hazards in cabling installations?

Neglecting cable installation standards can lead to a variety of safety hazards in cabling installations. When the proper standards and guidelines are ignored, several issues may arise. This neglect can affect cable performance and integrity, resulting in potential electrical shorts, signal loss, or even fire hazards. For instance, cables not installed according to standards may be improperly secured, which can lead to wear and tear defects over time and cause situations that could compromise system operation and safety. Additionally, failure to adhere to standards often results in non-compliance with local electrical codes, increasing liability and associated risks while impacting the overall quality and reliability of the installation.

The other options emphasize safe practices: proper bending techniques help prevent damage to the cabling, high-quality connectors ensure reliable connections that reduce the risk of failure, and routine testing of cables identifies issues proactively, thereby enhancing safety.
