¶ … Protection desired (Safety Factor)
Importance of Considering the level of Protection
In current decades, the industrial and process businesses have experienced fundamental changes with bringing in new types of safety protection when it comes to things such as electronics and microprocessor-based type of equipment in every feature of the industry. It is clear that these changes have introduced a new, very difficult class of gear with random failure design and a need for refined troubleshooting skills in regards to safety protection. As a result, when it comes to the importance of considering the level of protection desired it is important to develop management strategies in order to make sure that the required levels of plant uptime, cost and industry risk are met at the lowest likely cost.
When it comes to the importance of considering the level of Protection desired one of the first things that need to be addressed when it comes to the safety factor is knowing what to repair and also what needs to be replaced (Harris, 2010). Some experts believe that this is a critical question in regards to the safety factor because as it will define "spare" and the way failures are usually handled. The things that needs to be repaired depends entirely on the skills that are usually available in the maintenance/engineering department, not to mention the time it takes to repair as opposed to replace and then the cost of the downtime.
When thinking about safety factors Small VFDs desired and are packaged in such a way that maintenances in situ are not useful, so they are basically substituted with a replacement. The situation turn out to be complicated on the other hand, when larger drives are involved for the reason that there are a lot of failure modes - power module, crossing point boards and manager, just to be able to name a few. In such a situation, it is clear that management will...
This decision will be based on a number of safety factors, the most important things is making sure that whatever parts that are being used have the exact level of safety needed. Most experts would agree that experience has shown that even relatively large drives up to several hundreds of horsepower's should be replaced instead of repaired in-service as it is a better, more economical option when factoring in downtime involved during the repair process.
When dealing with the safety factor, this thought procedure would need to be applied to all fixed equipment - electrical, electronics, mechanical, pneumatic hydraulics (Hurnall, 2005). As soon as the repair strategy choice is made, the next things have a lot to do with performing operational and criticality examination in order to take the next steps with safety.
As software-intensive systems become more pervasive, a large number of safety-critical systems are being developed and fielded. To improve productivity, performance, and cost-effectiveness, many industries are out there developing more and more safety-critical systems that are under computer control. And centralized computer control is enabling many safety-critical systems in order for them to grow in size, complexity, and potential for disastrous miscarriage (Federal Chamber of Automotive Industries., 2015).
Other safety factors have a lot to do with software. Many utilize software in order to control our factories and refineries along with distribution and power generation. Software is also used in our transportation systems in addition to airplanes, trains, subways, ships, and even in family automobiles. Research shows that software is likewise a major constituent of a lot of medical organizations in which safe functioning is dangerous to the safety of patients and operators…
