Below are some concise answers with a general approach. Please keep in mind that certain answers/facts might vary based on different standards. Always adhere to the local rules, regulations, and standards applicable at your project or site.

1. Safety Officer responsibilities include implementing safety protocols, conducting inspections, and training employees.

2. The purpose of Hazard Identification is to recognize potential risks in the workplace.

3. IDLH stands for "Immediately Dangerous to Life or Health" - a term used to describe hazardous atmospheres.

4. Walkthrough is a site inspection to identify safety issues and potential hazards.

5. In a walkthrough, you'll check safety equipment, work processes, and potential risks.

6. Colour Coding uses specific colors to convey safety information or identify hazards.

7. During a crane lifting activity, you'll check safety procedures, lifting equipment, and clearance areas.

8. In case of an emergency on site, I'll follow the emergency response plan and ensure everyone's safety.

Hot Work:

1. Hot work involves operations like welding, cutting, or soldering that produce sparks and heat.

2. Hot work requirements include permits, fire safety measures, and a designated fire watcher.

3. A fire watcher is a trained individual responsible for fire safety during hot work operations.

4. A fire watchman should remain on-site for at least 30 minutes after finishing hot work.

5. The maximum distance of a Fire Extinguisher from hot work should be 10 meters.

6. Fire watchman responsibilities include monitoring, having firefighting equipment, and reporting hazards.

Scaffolding:

1. Scaffolding is a temporary structure used to support workers and materials during construction.

2. Types of scaffolding include tube and coupler, frame, and system scaffolding.

3. Scaffolding consists of parts like standards, ledgers, and transoms.

4. Hazards of scaffolding include falls, collapses, and falling objects.

5. Qualified workers can erect scaffolding based on safety regulations.

6. Scaffolding erection requires a work permit, usually issued by the site supervisor.

7. Scaffolding should be inspected by a competent person regularly.

8. Scaffolding tags include Red Tag, Yellow Tag, and Green Tag for different stages of inspection.

9. Red Tag indicates that scaffolding is not safe for use.

10. Yellow Tag indicates that scaffolding is safe for limited use.

11. Green Tag indicates that scaffolding is safe for full use.

12. Toe board is a barrier placed at the edge of scaffolding platforms to prevent materials from falling.

13. The maximum distance allowed between planks of scaffolding is 1 inch (2.5 cm).

14. The ladder placed on scaffolding should have a maximum angle of 75 degrees from horizontal.

15. Ladder should be extended at least 1 meter above the landing platform.

16. Bracket scaffolding is attached to the building, used when ground support is limited.

Excavation:

1. Excavation is the process of digging and removing earth to create a cavity or trench.
