A work method statement, sometimes referred to as a safe work method statement or SWMS or a safe work procedure, is a part of a workplace safety plan. [1] It is primarily used in construction to describe a document that gives specific instructions on how to safely perform a work related task, or operate a piece of plant or equipment. In many ...
A positive pressure enclosure, also known as a welding habitat or hot work habitat, is a chamber used to provide a safe working environment for performing hot work in the presence of explosive gases or vapors. They are commonly used in welding environments and are associated with the offshore oil industry. [1]
The lower limit of the hot working temperature is determined by its recrystallization temperature. As a guideline, the lower limit of the hot working temperature of a material is 60% its melting temperature (on an absolute temperature scale). The upper limit for hot working is determined by various factors, such as: excessive oxidation, grain ...
The purpose of a hot work permit is to effect "the employer's written authorization to perform hot working operations". [3] The UK's Health and Safety Executive suggests that a hot work permit should specify: what work will be done; how and when it is to be done; what safety and health precautions are needed; who is responsible for checking it ...
Hot stick or Live Line Tool Hot sticks are used in live line work by having the worker remain at a specified distance from the live parts and carry out the work by means of an insulating stick. Tools can be attached to the stick, allowing work to be performed with the worker safely away from the live conductors. Insulating Gloves or Rubber Gloves
The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment. Examples of work assignments include "operating a grinder," "using a pressurized water extinguisher" or "changing a flat tire." Each of these tasks have different safety hazards that can be highlighted and fixed by using the job safety analysis.
For example, a prudent designer will have allowed for foreseeable variations within the process, creating a larger design envelope than just the basic requirements, and the HAZOP will be looking at ways in which this might not be sufficient. A common use of the HAZOP is relatively early through the detailed design of a plant or process.
A permit-to-work system is a formal system stating exactly what work is to be done, where, and when. Permit-to-work is an essential part of control of work (CoW), a structured communication mechanism to reliably communicate information about hazards, control measures, and so on. During critical maintenance activities, good communication between ...
