The term "scaffolding" refers to a temporary structure used to support workers during construction processes. A scaffold is a network of planks and frames connected by various types of couplers and bolts.

Types of Scaffolding

• A single pole scaffold is made of a single row and is placed against the structure for support.
• A birdcage scaffold is made of two or more rows of vertical poles connected by transoms and ledgers.
• A suspended scaffold has a suspended framework.
• A cantilever scaffold is one that is supported at only one end.

The Occupational Safety and Health Administration enforces a detailed set of standards for the construction and installation of scaffolding. Manufacturers and construction site employers are required to follow these regulations to protect workers from scaffolding related accidents. Often, however, manufacturers and employers fail to adhere to OSHA's strict scaffolding standards, resulting in serious accidents.  Scaffolding related accidents can include falls from defective scaffolding, collapses, electrocutions and other accidents.

OSHA Scaffolding Standards

OSHA's standards for scaffolding include provisions for size, design and stability of guardrails, footings, platforms and protection systems as well as detailed provisions for erecting and dismantling the scaffolding.

Here are some of the provisions that affirm a scaffold's stability and safety.

• Workers who are positioned above 10 feet from a lower level must be equipped with a personal fall protection system.
• Scaffold footings must be even and strong enough to support the scaffold.
• Mid rails must be positioned halfway between the platform and top rail.
• The scaffold platform must be completely decked or planked.
• Scaffolds must be protected from tipping dangers during the use of guying ties.
• The height of top rails must be between 38 inches and 45 inches.
• Installation of a scaffold must be done by trained employees.
• A designated employee must conduct a thorough inspection of the scaffold before beginning the day's shift looking for visible signs of defects in the scaffolding framework, as well as components.
• The erection and dismantling processes must be supervised by a competent person.
• Ropes and wires used in scaffolding must be sturdy, strong and free of wear and tear.

Scaffolding work is often dangerous considering the chance of a collapse, injuries from falling objects, electrocutions due to contact with power lines, etc. That is why design and construction of a scaffold must be executed with adherence to safety standards. Most accidents can be avoided if scaffolding has been properly designed according to the size, location and shape of the building it is meant to support.
