Here are some common construction safety questions and key safety requirements based on the provided documents:

1. Housekeeping and Site Cleanliness: Employers must ensure that work sites are kept clean and free from materials or equipment that could cause workers to slip or trip. This includes regular removal of debris and proper storage of materials [1].

2. Lighting: Adequate lighting must be provided to ensure safe working conditions. Emergency lighting is required if workers are in danger if the normal lighting system fails [1].

3. Fall Protection: Employers are responsible for implementing effective fall protection systems, such as guardrails, safety nets, or personal fall arrest systems, especially in areas where workers are at risk of falling from heights [2].

4. Equipment and Material Safety: Equipment and materials must be properly secured to prevent them from being dislodged, moved, or damaged, which could pose a danger to workers [3].

5. Signallers and Communication: When signals are required, a designated competent worker must be assigned to give signals, and they must wear high-visibility safety apparel [3].

6. Fire Protection and Prevention: Employers must develop and maintain an effective fire protection and prevention program throughout all phases of construction work [4].

7. Personal Protective Equipment (PPE): Employers are responsible for ensuring that appropriate PPE is worn in operations where there is exposure to hazardous conditions [4].

These points highlight the importance of maintaining a safe construction environment through proper housekeeping, lighting, fall protection, equipment safety, effective communication, fire prevention, and the use of PPE. For specific situations or further details, consulting the full safety regulations and guidelines is recommended.
