American Welding Society
Compare and contrast the confined space recommendations made by the American Welding Society with those found in Chapter 13 of the textbook.
Chapter thirteen explains confined spaces, as open - topped areas of more than 4 feet in depth. The American Welding Society (AWS) defines this as small rooms, pits, vats, sewers and many other enclosed compartments. The differences between them, is chapter thirteen defines these areas specifically, based upon certain dimensions in contracts with the AWS. ("AWS Safety & Health Fact Sheets," 2013) (Suruda & Pettit, 1994)
Using other web resources, compare and contrast the AWS recommendations for controlling exposure to chromium and nickel welding fumes with those of other organizations. If you were the safety professional reviewing the hazards for manual welding involving exposure to these substances, what controls would you establish?
The AWS recommends not breathing gases and staying away from clouds of toxic fumes. They also state that there needs to be enough ventilation at the arc to keep the area breathable. In any situation,...
("AWS Safety & Health Fact Sheets," 2013) OSHA (Occupational Safety and Health Administration) is more in depth with their recommendations than the AWS. They encourage cleaning any toxic residue from the work area. At the same time, having it well ventilated, using an effective exhaust system and using lower fume consumables. ("OSHA Fact Sheet," 2014)
If I were a safety professional, there are many changes that would be recommended. First, I would require that any welders, in a confined space, to have a local ventilation system. This means using a lower fume - generating or less toxic welding type of consumables. At the same time, respiratory protection would be required if ventilation does not reduce the exposure the welder receives to toxic fumes. Those who are working a poorly ventilated area would be fined up to $1,000.00. When welding outdoors or inside open areas, it is imperative to be aware of weather related factors such as wind. This could cause fumes to spread over larger areas.

Self-awareness is a major key to promoting ergonomics in the workplace, because only through self-awareness can an individual realize that he or she is sitting, standing, moving, or working according to ergonomic principles. Ergonomics applies also to product design and engineering. For example, new machinery is being designed according to well-researched principles of ergonomics. Similarly, office equipment, from chairs to computer keyboards, are also being redesigned with worker safety
Designing a Safety System Safety management system is a management policy to prevent or minimize injury within a workplace. Top organizations across the United States are increasingly investing in safety management because of the general believe that safety is central precondition to market competitiveness and "an integral part of high quality business operations." (Tervonen, Haapasalo, & Niemela, 2009 P. 17). Safety is defined as a state where all the business related
Aviation Safety Program Management The average air traveler rarely sees the essence of recognizing the aviation safety regulations in place. People only and often recognize the factors of safety after a horrific accident occurs. Within the daily working schedules in the private and commercial flights, countless lives of innocent passengers depend on the full implementation of the safety regulations. These safety procedures are in place to protect the lives of the
It is essential for company managers, safety practitioners and manufacturing engineers to be informed of and gain sufficient knowledge about current research developments in this field and implement safety strategies as well as systems to minimize occupational health and safety risks. (Bier; Kunreuther; Phimister, 103); (Stellman, 17) Active and procedural risk management strategies are important elements in any manufacturing unit. Active risk management refers to implementing interlocks, alarms and mitigation
Workplace Safety Safety within the workplace is a central issue that Occupational Safety and Health Authority hold with the highest consideration than any other matter within the workplace that can potentially affect the employees. OSHA has in place lucid rules and regulations guiding the safeguarding of the employees safety within organizations. There are various initiatives taken by organization to ensure that there is safety within the workplace. Regardless of the safety
