When encountering a hazard in the workplace, the hierarchy of hazard control provides a systematic approach to identify the most appropriate actions for controlling or eliminating that hazard. Additionally, it aids in developing a comprehensive hazard control plan for implementing the chosen measures effectively in the workplace.
The phases of jet-grouting work are: Perforation phase: insertion, with perforation destroying the nucleus, of a set of poles into the ground up to the depth of treatment required by the project. Extraction and programmed injection phase: injection of the mixture at very high pressure is done during the extraction phase of the set of poles.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) is a United States Department of Transportation agency created in 2004, responsible for developing and enforcing regulations for the safe, reliable, and environmentally sound transportation of energy and other hazardous materials.
Workers in highway work zones are exposed to a variety of hazards and face risk of injury and death from construction equipment as well as passing motor vehicles. Workers on foot are exposed to passing traffic, often at high speeds, while workers who operate construction vehicles are at risk of injury due to overturn, collision, or being caught ...
Complete elimination of a hazard is often the most difficult control to achieve, but addressing it at the start of a project allows designers and planners to make large changes much more easily without the need to retrofit or redo work. Understanding the 5 main hazard areas is a major part of assessing risks on a jobsite.
Mitigation planning helps local governments lessen the impacts of hazards within their communities. [15] No two locations have the same hazard risks and communities know their experiences best. For example, even if a hazard is not recorded in government data, locals will take note of anything that occurs in their neighborhood. Policymakers can ...
In the United States, compensatory mitigation is a commonly used form of environmental mitigation and, for some projects, it is legally required under the Clean Water Act 1972. Compensatory mitigation is defined by the US Department of Agriculture as "measures to restore, create, enhance, and preserve wetlands to offset unavoidable adverse ...
A root cause analysis identifies the set of multiple causes that together might create a potential accident. Root cause techniques have been successfully borrowed from other disciplines and adapted to meet the needs of the system safety concept, most notably the tree structure from fault tree analysis, which was originally an engineering technique.
