What should be avoided unless otherwise required during construction?

1. Use of heavy machinery

2. Use of acid or caustic solutions

3. Use of safety gear

4. Use of scaffolding

The correct answer is: Use of acid or caustic solutions

The use of acid or caustic solutions should be avoided unless otherwise required during construction because these substances can pose significant hazards to workers, the environment, and surrounding structures. These materials often come with strict handling and disposal regulations due to their potentially harmful effects, which include chemical burns, respiratory issues, and environmental contamination. In construction practices, the safety of personnel and the integrity of the built environment are paramount. Therefore, it is essential to prioritize safer alternatives or methods for construction that do not involve these potentially dangerous chemicals unless they are specifically necessary for a particular task and all safety protocols can be properly implemented to mitigate risks. This focus on safety aligns with best practice standards in the construction industry, which aim to protect both workers and the public.
