Which is an example of a safe work practice at a construction site?

• A. Fall protection and training when working at high levels
• B. Climbing scaffolds without guardrails
• C. Operating machinery without guards
• D. Ignoring trench inspections

Answer: (A)

When workers are at heights, using fall protection and receiving proper training is a safe work practice. Falls are one of the most serious hazards on construction sites, and protecting workers with equipment like guardrails, safety nets, or personal fall arrest systems, plus training on how to work safely at height, dramatically reduces the risk of injury or death. This combination—protection plus documented training—addresses the hazard directly and is supported by construction safety standards.

The other options illustrate unsafe practices: climbing scaffolds without guardrails removes a critical safeguard; operating machinery without guards exposes workers to moving parts; and ignoring trench inspections can miss dangerous conditions like soil failures. Each of these increases the likelihood of serious harm, so they’re not considered safe work practices.
