What is a scaffold safety inspection requirement on Singapore construction sites?
Answer: Scaffolds must be inspected by a competent person before first use, after modification, and at regular intervals
Scaffolds must be inspected by a competent person before initial use, after any modification or adverse weather, and at regular intervals (typically weekly) to ensure structural integrity and safety.
What is a 'safety net' used for in Singapore construction?
Answer: A mesh net installed below work areas to catch workers who fall, serving as a collective fall arrest system
Safety nets are installed below elevated work areas as a collective fall arrest measure. They must be positioned close to the work level and inspected regularly for damage or deterioration.
What is a 'travel restraint system' in the context of working at heights in Singapore?
Answer: A system that prevents the worker from reaching an unprotected edge by limiting their travel distance
A travel restraint system uses a harness and lanyard combination that physically prevents the worker from reaching a fall hazard zone, such as an unprotected edge of a building.
What is the maximum free-fall distance allowed for a personal fall arrest system on Singapore construction sites?
Answer: The system must limit free-fall distance to 2 metres or less and total fall distance must not result in the worker hitting any lower level
Personal fall arrest systems must be designed and used so that the maximum free-fall distance does not exceed 2 metres, and the total arrest distance (including deceleration) does not allow contact with any lower level.
What rescue plan requirements exist for work at heights on Singapore construction sites?
Answer: A rescue plan must be developed before work begins, detailing how fallen workers will be retrieved promptly to avoid suspension trauma
Employers must have a rescue plan in place before any work at heights begins. Prolonged suspension in a harness can cause suspension trauma, so prompt rescue is critical.
What are the requirements for ladder safety on Singapore construction sites?
Answer: Ladders must be in good condition, secured at top and bottom, extend 1 metre above the landing, and only one person may use a ladder at a time
Ladders must be inspected, set at the correct angle (1:4 ratio), secured against displacement, extend at least 1 metre above the landing platform, and only be used by one person at a time.
