Part 1 - Scaffolding Terminologies HAZARDOUS AREA CLASSIFICATION PART 4 Part 2 - Confined Space Rescue Plan Scaffolding operation in any industry is considered as highly technical operations with serious hazard potential. Unless correct steps are taken, a loss prevention program at work site, it may end up with serious trouble with loss in job schedule, injury to workmen, company image and damage to property. Hence, to perform the job safely, knowledge on scaffolding , safe erection and maintenance & inspection are essential to the execution team. The scaffolding is having many types like roof scaffolding, hanging scaffold, suspended scaffolding, mobile scaffold platform, rolling scaffold, aluminium scaffolding, mobile aluminium scaffold, U Jack scaffolding, portable scaffold tower etc. Scaffold Terminologies Anchorage : Safe points of anchorage for lifelines or lanyards, which are part of a personal fall arrest system, including fixed, substantial structural members. Anchorage points shall be fixed and able to support a load of at least 2,300 kilograms (5,000 pounds). Base Plate : A steel plate providing a flat bearing surface with a spigot or screwjack for distributing the load from posts (standards). It has an integral spigot and fixing holes for use with sills. Safety Alert - Hydra Crane Toppling Bearer (Transom) :A horizontal transverse scaffold member, that may support platform units, and which is supported by at least two runners (ledgers) or connected directly to at least two posts (standards). Board Bearer (Intermediate Transom) : A horizontal transverse scaffold tube upon which the scaffold platform partially rests. Board bearers are supported by runners (ledgers) and are not installed near a transverse line of posts (standards). Brace : A rigid connection of scaffold tubing that holds one scaffold member in a fixed position with respect to another member to give the scaffold rigidity. Cross Bracing : Two diagonal braces joined at their center to form an “X.” Also called “X” bracing or cross braces. HAZOP STUDY METHODOLOGY IN SAFETY – Basic Diagonal Brace : A scaffold tube placed diagonally with respect to the vertical and horizontal members of a scaffold and fixed to them to give the scaffold stability. Longitudinal (Facade or Sway) Bracing : Diagonal braces installed in the plane of the longer dimension (length) of the scaffold. Plan Bracing : Diagonal braces installed in a horizontal plane, particularly used in mobile and tower scaffolds. Transverse (Sectional or Ledger) Bracing : Diagonal braces installed in the plane of the shorter dimension (width) of the scaffold. Zig-Zag (Dog-leg) Bracing : Diagonal braces placed end-to-end and that alternate back and forth. Incident Accident Investigation Case Study Animation Fall Protection in Construction – OSHA
