Abstract Within the oil and gas industry, some physical jobs haven't changed for years. Even today, many of the tasks performed on-site and in the field are physically demanding - so much so that many tasks exceed the long-term physical capability of most operators. Over time, we have seen workers gradually ‘wear out’ physically and self-elect to move into tasks that are less demanding, but also less rewarding. In our opinion, it does not have to be this way. The objective of this paper is to demonstrate how physically demanding jobs can be analyzed and how practical, cost-effective changes can be made to reduce the physical stress on the operator. It is our goal to demonstrate how positions that are now seen as ‘interim work’ can be made into careers that workers can perform into their retirement.
Introduction In 1700 Dr. Bernadino Ramazzini published the first edition of what was to become one of the most quoted books on occupational disease, De Morbus Artificum Diatriba [Diseases of the Worker]. Ramazzini was the first person to establish a link between hazards in the workplace and human illness and injury. In one passage, he stated (Mandel, 2003):"Various and manifold is the harvest of diseases reaped by certain workers from the crafts and trades that they pursue. All the profit they get is fatal injury to their health, mostly from two causes. The first and most potent is the harmful character of the materials they handle. The second I ascribe to certain violent and irregular motions and unnatural positions of the body, by reason of which the natural structure of the vital machine is impaired so serious disease gradually develops there from"
Illnesses and injuries were often named from the occupation of the people who suffered the injury - "brick layers thumb, reed maker's elbow, flute player's hand". Many of these injuries were suffered early in the worker's career and required the worker to retire early from the occupation. We have the opportunity today to prevent a legacy of illnesses that future generations may refer to as ‘driller's neck’, ‘floorman's elbow’ or ‘roughneck's back’.
Elimination of the conditions that cause serious injuries due to repeated trauma is possible through the application of Human Factors principles. Human Factors/Ergonomics is defined as the systematic process of designing for human use through the application of our knowledge of people to the equipment they use, the environments they operate in, the tasks they perform and the management systems that guide the safe and efficient operations of the equipment they work with. Neglecting any of these elements could lead to the failure of the entire facility. The key word in the above definition is "systematic". Human Factors has been applied in heavy industry for many years. But, too often the application employs a trial and error approach - try a design then change it when is doesn't work — that is guided by common sense rather than by good science. The problem with not getting the design right the first time is that it can lead to inefficiencies, retrofit costs and, too often, the error from which we learn is found through a worker injury.
The model presented in Figure 1 depicts the systematic process of designing for humans. It begins with understanding the standards that guide the way your operation is designed, operated and maintained. It then identifies and prioritizes the most significant issues in your operation, analyzes the critical issues and implements the best solutions. Finally, the model makes sure that the results of the solution are measured, so you know that it works.
In the paragraphs to follow, the case studies that are presented were identified, analyzed against applicable standards, and solutions were generated and measured according to the model presented above.
