Construction Skills Certification Scheme (CSCS) Practice Test

In planned work involving cutting or grinding materials, which two methods are effective for controlling dust?

1. Using a low-speed tool and covering the area

2. Fit a dust extractor or collector to the machine and wet cutting

3. Frequent breaks and hydration

4. Using manual tools only

The correct answer is: Fit a dust extractor or collector to the machine and wet cutting

When dealing with cutting or grinding materials, controlling dust is crucial for health and safety on construction sites. Fitting a dust extractor or collector to the machine significantly reduces airborne particles by capturing dust at the source, minimizing inhalation risks for workers nearby. Additionally, wet cutting is an effective method that suppresses dust creation by using water to dampen the material being worked on, which binds the dust particles and prevents them from becoming airborne. This combination of using a dust extraction system and wet cutting ensures a cleaner working environment and compliance with health and safety regulations. Other options may not provide effective dust control. Using low-speed tools and covering the area can help to some extent, but it may not prevent dust from escaping as effectively as a dust extractor. Frequent breaks and hydration are related to worker safety and comfort, but they do not actively control dust levels in the environment. Relying on manual tools only may limit the effectiveness of dust control methods, as many manual processes can still generate significant dust without mitigation techniques.
