Here are some common construction safety questions along with their answers based on the provided documents:

1. What are the housekeeping requirements on a construction site?

   • 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 providing containers for waste separation and disposal [1].

2. What are the lighting requirements for construction sites?

   • Employers must ensure that lighting at a work site is sufficient to enable work to be done safely. Emergency lighting must also be available if workers are in danger if the normal lighting system fails [1].

3. How should hoses and piping be managed to ensure safety?

   • Hoses or piping operating under pressure must be restrained to prevent injury from movement if they fail or disconnect. If they cannot be restrained, they must be designed, installed, and maintained according to the manufacturer's specifications or certified by a professional engineer [2].

4. What are the requirements for securing equipment and materials?

   • Both employers and workers must take all reasonable steps to ensure that equipment or material is contained, restrained, or protected to eliminate potential danger [2].

5. What are the requirements for fall protection on construction sites?

   • Workers must be protected from falling by guardrail systems, safety net systems, or personal fall arrest systems when working at heights. Specific requirements apply to different situations, such as working near holes, on ramps, or near dangerous equipment [3].

6. What precautions should be taken when working near energized overhead power lines?

   • Employees should not approach or take conductive objects closer to energized parts than prescribed unless they are insulated or the parts are de-energized and grounded [4].

These answers are based on the Occupational Health and Safety Code and other relevant safety regulations. Always ensure compliance with local regulations and standards for specific requirements.
