Working at height (typically

1.8m-2m) requires a Permit to Work (PTW), 100% tie-off using full-body harnesses, and certified scaffolding, backed by HIRA/JSA to mitigate fall hazards. Key controls include medical fitness checks, edge protection, tool lanyards, and supervisor inspection.

Q1: What are the primary legal requirements for working at height?

A: Regulations mandate that all work at height must be properly planned, supervised, and carried out by competent persons. Key legal duties include conducting a HIRA/JSA, issuing a PTW, and providing suitable PPE (e.g., full-body harness).

Q2: What is the difference between HIRA and JSA for height work?

A: HIRA (Hazard Identification & Risk Assessment) identifies risks for the entire project/workplace, such as falling from height or structural collapse. JSA (Job Safety Analysis) breaks down specific tasks (e.g., scaffolding erection) to identify hazards in each step and define controls.

Q3: According to SOP, what constitutes proper fall protection?

A: A full-body harness must be used, 100% tied off to a secure anchor point. Where guardrails are not possible, fall arrest systems or safety nets must be used.

Q4: What are the critical elements in a Work Instruction (WI) for scaffolding?

A: 1. Baseplate on firm foundation. 2. Verticality check. 3. Proper bracing and locking pins. 4. Guardrails (mid and top) and toe boards. 5. Daily inspection and safe-to-use tag.

Q5: What are the main hazards identified in a JSA for height work?

A: Main hazards are falls from height, falling objects (tools/materials), scaffold collapse, electrocution (overhead power lines), slips and trips, and extreme weather.

Q6: What is required for a worker to be considered "competent" to work at height?

A: The worker must be medically fit (no vertigo/heart conditions), trained in harness usage, aware of rescue procedures, and authorized by a supervisor.

Q7: What is the 100% tie-off principle?

A: The worker must ensure they are connected to an anchor point at all times using a double-lanyard harness, especially when moving between points, ensuring one lanyard is always hooked.

Q8: What should be done in case of a suspended worker?

A: Initiate the Emergency Response Plan (ERP) immediately, use pre-planned rescue equipment (rescue ladder or platform) to lower the worker safely to prevent suspension trauma, and provide medical attention.
