What is a potential hazard of working in dust when laying drains?

When working in dust while laying drains, respiratory issues are a significant concern. Dust can consist of various particles, including silica, asbestos, and other harmful substances that, when inhaled, can lead to serious health problems. These issues can range from acute respiratory infections to chronic conditions such as silicosis or asthma.

Individuals who are frequently exposed to dust without adequate respiratory protection face an increased risk of developing these conditions over time. Effective measures, such as wearing dust masks or respirators, can substantially mitigate these risks and protect lung health.

While skin irritation can occur from contact with dust, it is not as critical of a hazard as respiratory issues, which directly affect the lungs and overall health. Electrical shock and heat exhaustion are also less relevant in this context, as they involve different environmental factors unrelated to dust exposure.
