Safety Not Suspended on Platforms

We've seen those who work high above the ground, suspended on platforms as they construct buildings, wash windows or make repairs.

Types of suspended work platforms
Swing stages are the most commonly used suspended work platforms (suspended platforms or suspended scaffolds). They are used for window cleaning or conducting repairs to the exterior of buildings and consist of a work platform, guardrails and a suspension system.

Multi point suspended scaffolds are specialized suspended work platforms that have specific design and operational requirements.

Hazard
The most significant hazard associated with swing stages is workers falling from height. Workers can also fall if the swing stage over-turns because the counterweight does not have the adequate weight or if point of support at the edge of the building fails. The swing stage can also collapse if it is overloaded, the platforms are not attached properly, or if the motors, platforms or wire ropes are damaged from exposure to chemicals or corrosive materials, or not properly maintained.

Hazard Controls
Employers and supervisors are required to take every precaution reasonable in the circumstances to ensure the health and safety of workers. The MOL outlined the following guidance to control the hazards.

Proper training: Workers working on a suspended platform or suspended scaffold who may use a fall protection system must receive comprehensive fall protection training. They must also be trained how to use and inspect the platform or scaffold.

Fall arrest system: A worker who is on - or is getting on or off - a suspended platform or suspended scaffold must wear a full body harness. The harness must be connected to a fall arrest system with an independent lifeline, or that is securely fastened to a suspended platform or scaffold that has more than one independent means of support.

Proper design, construction and use of equipment: Every suspended platform or suspended scaffold must be installed, maintained and used according to all safety regulations, standards and the manufacturer's specifications. The platform must not be overloaded. Equipment must be maintained in a condition that does not endanger a worker. Scaffolds with more than one platform or that exceed weights prescribed in safety regulations must be designed, erected and inspected according to applicable regulations.

Maintenance of equipment, materials and protective devices: Employers must ensure that the equipment, materials and protective devices are maintained in good condition.

Proper inspection of equipment: Suspended platforms or suspended scaffolds must be inspected by a competent worker each day and before they are used, and at the start of each shift.
