In demolition safety, this control is characterized by ensuring separation between the public and the demolition activities

Installation of scaffolds, platforms, guardrails, shoring and bracing to support loads are examples of this type of risk control.

This type of risk control includes limiting the amount of time a person is exposed to a particular hazard, implementing safe working procedures for all hazardous tasks, and training all personnel.

Primary cause of accident that is characterized by the human action that departs from a standard or written job procedure or common practice, safety rules, regulations, or instructions.

The physical or chemical property of a material, machine or the environment which could result in injury to a person, damage or destruction to property or other forms of losses.

A risk associated with poorly guarded or dangerous equipment and machinery that may cause injury.

A risk associated with exposure to dangerous substance or conditions that may cause illness/disease.

An engineering control or PPE set that protect you after you fall which is characterized by stopping the fall before you hit the surface like net/mesh and/or body harness.

An engineering control or set of PPEs prevents you from falling like guardrails, covers, restraints, etc.

A formal process to identify the dangers of specific job tasks in order to reduce the risk of injury to workers. It involves breaking down the steps of performing a job, identifying hazards at each step, and creating controls to keep workers safe while performing that task.

A formal process to identify potential hazards related to an activity or operation, analyze the level of risk associated with those hazards, and propose controls to reduce the level of risks.

This is the vertical member of shoring and timbering which directly resists pressure from side of an excavation.

A general term used to describe a temporary structure of timber or metal work with a platform used in the construction, alteration, or demolition of a building, or other maintenance work used to support workers or to allow the hoisting and lowering of workers, their tools, and materials.

A scaffold hanging by means of ropes or chains capable of being lowered or raised by winch, pulley, block, or such other means.

A platform supported by a single row of uprights or standards tied along the wall, connected horizontally by a ledger, and supporting putlogs which rests on ledger on one side and in holes left in walls on the other.

A platform supported on two rows of uprights or standards parallel to the wall of a building connected by horizontal ledgers and is independent from the building wall.

It is the vertical member of scaffold transmitting the load to the ground or to a base plate.

A scaffold bracing, which extends horizontally from standard to standard forming right angles with the putlogs and forms a tie between the standards.

A scaffold member spanning between a ledger and a building wall or between two ledgers upon which the platform rests.

A scaffold member that holds standards or uprights in a fixed position to prevent any lateral movement.
