Worked Solution & Example Answer:Discuss in detail one possible safety risk associated with each of the following tasks on a construction site: - excavating where there are underground electrical cables - working in a deep trench - working at height when slating a roof - Leaving Cert Construction Studies - Question 2 - 2018
Step 1
excavating where there are underground electrical cables
Answer
One possible safety risk involved in excavating where there are underground electrical cables is the danger of electrocution. If an excavator inadvertently damages or contacts electrical cables, it can lead to severe electrical shock or even fatal injuries. It is crucial to ensure that workers are aware of the location of these cables and follow safety protocols to mitigate this risk.
Step 2
working in a deep trench
Answer
A primary risk associated with working in a deep trench is the potential for collapse, which can result in workers being trapped or crushed. This hazard emphasizes the need for proper trenching techniques and support systems to ensure the safety of workers inside the trench.
Step 3
working at height when slating a roof
Answer
When working at height while slating a roof, the risk of falls is significant. Workers can easily slip or lose balance, potentially leading to serious injuries or fatalities. Adequate safeguards, such as guardrails, harnesses, and scaffolding, should be deployed to protect workers from falling.
Step 4
For each risk discussed at 2(a) above, show, using notes and freehand sketches, two best practice guidelines that should be observed to reduce the possibility of injury to a worker undertaking each task.
Answer
-
Excavation Guidelines:
- Dial before you dig to confirm cable locations, thus reducing the chance of damage.
- Use appropriate protective gear and equipment while working near identified zones of underground cables.
-
Deep Trench Guidelines:
- Ensure trenches are shored properly to prevent collapse, using proper support mechanisms as needed.
- Maintain a clear perimeter around the trench with visible barriers to ensure that no unauthorized personnel enter the hazardous area.
-
Working at Height Guidelines:
- Install safety rails and ensure workers use harnesses secured to stable points while on roofs.
- Use non-slip footwear and provide safety nets below to capture any falling workers or materials.
Step 5
Discuss in detail three strategies that would promote a positive safety culture among workers on a construction site.
Answer
-
Buddy System: Implement a system where new employees are paired with experienced workers. This mentoring approach ensures that safety practices are communicated effectively.
-
Regular Safety Meetings: Hold frequent safety meetings to discuss potential risks and review safety procedures. These meetings provide a platform for workers to voice concerns and share experiences related to safety.
-
Training and Certification: Ensure that all workers receive proper training and are certified for the tasks they perform. Adequate training not only equips workers with necessary skills but also fosters a greater sense of responsibility towards safety.
