Introduction Safety-critical systems are ever increasing in day to Safety-Critical Systems are those systems whose failure day life such as use from microwave oven to robots could result in loss of life, significant property damage, involving computer systems and software. Safety- or damage to environment (Knight, J.C, 2002). Safety in critical systems must consider safety engineering and broad pertains to the whole system, computer hardware, safety management principles in order to be safe when software, other electronic & electrical components and they are put into use. Safety analysis must be done. stake holders. A safety-critical system is such a system Safety assessment of such systems is difficult but not impossible. They must deal with the hazards analysis which has the potential to cause hazard either directly or in order to reduce or prevent risks to environment, indirectly. The emphasis of this paper is on the element property damage and / or loss of life through risk-free of software for such safety critical systems, which can and failure free or fail-safe operations. The existing be referred to as safety critical software. Some of the methods are found to be limited and inadequate safety critical applications include flight control systems, to address the risks associated and for safety medical diagnostic and treatment devices, weapon assessment. This paper proposes a methodology for systems, nuclear power systems, robots and many. Failure safety assessment of safety critical systems based on free and risk free or fail-safe operations may not lead to identifying significant and non-significant aspects of hazards.

Risk Management – an Area of Knowledge for All Engineers
RISK MANAGEMENT – AN AREA OF KNOWLEDGE FOR ALL ENGINEERS A Discussion Paper By: Paul R. Amyotte, P.Eng.1 & Douglas J. McCutcheon, P.Eng.2 1Chemical Engineering Program Department of Process Engineering & Applied Science Dalhousie University Halifax, Nova Scotia, Canada B3J 2X4 <[email protected]> 2Industrial Safety & Loss Management Program Faculty of Engineering University of Alberta Edmonton, Alberta, Canada T6G 2G6 <[email protected]> Prepared For: The Research Committee of the Canadian Council of Professional Engineers October 2006 SUMMARY The purpose of this paper is to “seed” the discussion by the Research Committee of the Canadian Council of Professional Engineers (CCPE) on the topic of risk management. The paper is in part a research paper and in its entirety a position paper. As can be inferred from the title, the authors hold the firm opinion that risk management is an area of knowledge with which all engineers should have familiarity and a level of competence according to their scope of practice. The paper first makes the distinction between hazard and risk. The two terms are often used interchangeably when in fact they are quite different. A hazard is a chemical or physical condition that has the potential to cause harm or damage to people, environment, assets or production. Risk, on the other hand, is the possibility or chance of harm arising from a hazard; risk is a function of probability and severity of consequences. A description of the process of risk management is then given. A generic framework for risk management is presented to illustrate the essential activities of hazard identification and the analysis, assessment and management of risks.

Safety Engineer What Do They Do? Safety Engineers Make Sure Workplaces Are Safe
Safety Engineer What Do They Do? Safety Engineers make sure workplaces are safe. They monitor the general work environment, inspect buildings and machines for hazards and safety violations, and recommend safety features in new processes and products. Safety Engineers evaluate plans for new equipment to assure that it is safe to operate and investigate accidents to determine the cause and how to keep them from happening again. Safety Engineers also design special safety clothing and safety devices to protect workers from injury when operating machines. They may educate workers through safety campaigns or classes. Some Safety Engineers specialize in fire prevention They analyze the design of buildings and the items in them to determine the best place to put fire extinguishers, sprinklers and emergency exits. Others specialize in product safety. They conduct research to make sure products are safe and recommend how a company can change its product design to make it safe. What Do I Have To Do To Be One? To work as a Safety Engineer, you must have a Bachelor's Degree in Industrial Engineering; Industrial Management or a related field. People who work in this occupation are curious and detail-oriented; have strong analytical skills; and are creative. Some courses to take to prepare you for this occupation include: Chemistry, Computers, Communications, English, Math, and Science. You should also be able to present your ideas effectively both orally and in writing. You should be able to work within precise limits or standards of accuracy and rate information using standards that can be measured or checked. How Much Do They Make? Salaries of Safety Engineers usually depend on their education level, work experience, area of specialization and level of responsibility.

Lockout/Tagout: Don't Flip out Over LOTO Compliance
COVER STORY Lockout/Tagout: Don’t Flip Out over LOTO Compliance Update your understanding of this life- and limb-saving standard. By Evelyn Sacks welder was crushed to death by a hydraulic door on a scrap met- al shredder. He was trying to remove a jammed piece of metal from the door. "e system’s energy had not been released, and the door had not been blocked open. A mechanic was fatally crushed in an escalator while per- forming maintenance. He had removed the escalator stairs and crawled inside the escalator mechanism. When a coworker Adropped the escalator’s electrical circuit box, it triggered a relay that sent power to the escalator. "e stairs began moving, and the mechanic could not escape. "e escalator had no locks or tags on any power controls. "ese grizzly examples are typical of the estimated 150–200 fatalities (and 50,000 or so injuries) that occur each year due to a failure to control the release of hazardous energy. Lockout/tagout (LOTO) 1910.147 refers to the Occupa- tional Safety and Health Administration (OSHA)-required practices and proce- dures to protect workers from unexpected start-up of machinery or from haz- ardous energy released during service or maintenance. "e standard is based on the fact that simply turning equipment o# is not enough to block stored energy. Lockout devices hold energy-isolating equipment in a safe or o# position. "ey prevent equipment from becoming energized because the lockout devices cannot be removed without a key or other unlocking mechanism. Tagout devices, by contrast, are prominent warning devices that are fastened to energy-isolating devices to warn employees not to reenergize the machine while they are being serviced or maintained.

Auditory Hazards of Air Bags March 27, 1997 Dr. Ricardo Martinez
Auditory Hazards of Air Bags March 27, 1997 Dr. Ricardo Martinez, Director National Highway Traffic Safety Administration (NHTSA) 400 7th Ave. SW Washington, DC 20590 Dear Dr. Martinez: As the President of the National Hearing Conservation Association (NHCA), I am writing to you about the problems created by the government mandate requiring air bags to be installed in all new U. S. automobiles. Although we are sensitive to the fact that airbags have saved approximately 1500 lives, that is only part of the story. As the President of an association whose mission is the prevention of hearing loss due to noise and other environmental factors, I urge you to reconsider your position. The NHCA is an organization of professionals who share a common goal - the prevention of noise-induced hearing loss. The Association is composed of audiologists, physicians, industrial hygienists, safety specialists, engineers and scientists, occupational health nurses, equipment manufacturers, and others, all of whom are concerned with the prevention of hearing loss for the 30+ million Americans who are exposed to hazardous noise at work. NHCAs interests extend to all situations in which hazardous noise exists, whether occupational settings in industry, construction, farming, or the armed forces. As well, NHCA is interested in preventing noise-induced hearing loss in non-occupational applications in the consumer and recreational sectors. Although it is true that airbags can save lives, data as reported on the NHTSA web page indicate that approximately 60 lives have been lost due to airbag deployments. It does seem tragic indeed that drivers have no choice about whether they put a potentially lethal device in their cars, when alternatives such as lap and shoulder belts exist and are finding increasing use among the public.
