What must be provided when there is a risk of materials falling in a work area?

• A. Safety helmets
• B. Warning signs only
• C. Protective barriers or covers
• D. Adequate protection for safety

Answer: (D)

When there is a risk of materials falling in a work area, providing adequate protection for safety is crucial. This includes implementing comprehensive safety measures that adequately shield workers from potential hazards. Adequate protection can encompass a variety of elements such as personal protective equipment, proper training for workers, and establishing effective protocols to mitigate risks associated with falling materials.

While safety helmets are important and can protect against head injuries, they are just one aspect of a broader safety strategy. Warning signs serve to inform workers of hazards, yet they do not physically prevent incidents from occurring. Protective barriers or covers are also directly relevant to preventing materials from falling, but the concept of "adequate protection for safety" encompasses these barriers along with other necessary measures to ensure a safe working environment. Thus, the correct answer emphasizes a holistic approach to safety in the face of potential risks.
