Construction Health and Safety Technician (CHST) Practice Test

What must be done to identify any potential hazards before starting excavation activities?

1. Notify local authorities

2. Conduct a thorough site assessment

3. Secure necessary permits

4. All workers must attend a safety meeting

The correct answer is: Conduct a thorough site assessment

Conducting a thorough site assessment is essential before starting excavation activities because it allows for the identification of potential hazards that could risk the safety of workers and the integrity of the project. This process involves examining the specific site conditions, including soil characteristics, the presence of underground utilities, environmental conditions, and neighboring structures. By identifying these hazards upfront, effective control measures can be developed to mitigate risks, ensuring a safer working environment. While notifying local authorities, securing necessary permits, and holding safety meetings are also important steps in the excavation process, they do not specifically focus on the identification of hazards related to the site itself. Each of these activities serves different purposes in the overall planning and execution of excavation work, but a thorough site assessment directly addresses the need to proactively manage risks associated with the excavation activities. Therefore, it is a critical step in maintaining workplace safety and compliance with regulations.
