Don't Take These Arc Flash Analysis Shortcuts!

Eliminate Short Circuit Analysis and Coordination Device Study

Problems: The short circuit analysis and coordination device study accurately model your electrical distribution system, and without knowing this, engineers are guessing. There are a few inherent dangers here. First off, the danger of the arc flash and blast is calculated both in terms of energy AND time. An arc flash incident point with a lower level of energy may be more dangerous that a higher voltage area because of the time for the breaker to pop. Without knowing this, engineers must take a guess and make one of two decisions; A) assume the best case scenario and rate the category based on that, leaving someone with category 2 clothing and equipment exposed to a category 3 or 4 situation. Should an accident happen here, an investigator may find your company to blame for excessive damages that could have been avoided. B) assume the worst case scenario and base the categories on this. This is the path that most engineers take because it covers them and the maintenance technician. Here’s the problem – this might actually be a category 2 situation and the engineer will make it category 3 to cover everyone. You now just saved $3K on engineering, but now need to go out and buy $10K in PPE & tools to meet category 3. The other big factor is that the higher the category of PPE, the more hot and restrictive it is for the technician to work and the longer it takes. One of the goals of your program is to get everyone in the best possible situation to do their job safely, not to overburden them and the company with unnecessary equipment.

Eliminate corrective actions investigation

Problems: The reality is that few companies actually do this, primarily because they do not understand the real world applications of an electrical distribution system and how electrical technicians work on them. When engineers identify a design flaw that either makes your system less efficient or puts workers at higher risk for shock or arc flash, they should make corrective recommendations to you before the arc flash analysis is completed. There is a reason that the breaker in your lunch room keeps popping when you plug in the coffee pot that requires a call to maintenance! A corrective actions investigation will make your system more efficient and safe, but this too can only be done if the short circuit analysis and coordination device study is completed. Simply changing a breaker out for a different one could save you tens of thousands of dollars over time.

Be sure your analysis provider provides you with the complete study. Work Safely!

Leveraging Your CMMS for Improving Plant Efficiency

A computerized maintenance management system (CMMS) is essential for efficiently managing any maintenance program. Managers and technical personnel alike rely on the software to set budgets, perform tasks and manage productivity. In too many cases, however, the CMMS is not producing the desired result and incorrect information is being provided to guide the maintenance program. With lean departments and increasing dsire by management to control costs, having a well-functioning CMMS system is critical to the success of any maintenance department.

An experienced CMMS consultant has a deep understanding of the current problems most organizations face with their CMMS. Working closely with the facility organization, they can identify gaps, provide practical corrective actions and develop a guide for future planning. An audit of the CMMS should also include the basis to decide if upgrading is necessary.

Here is what to expect with such an audit. And, by the way, the cost of an audit has a very high rate of return, often saving tens to hundreds of thousands of dollars in the first year.

Look for: Documentation of strengths/weaknesses and opportunities for improvement; better budget planning; justification for improvement projects; achievement of maintenance and reliability goals; better parts inventory management; and, overall cost reductions and productivity improvement.

The flow of new improvement ideas continue as higher levels of control and savings can help finance future improvements, further enhancing the audit, planning, scheduling and control cycle and ensuring a steady flow of better methods, savings and a more reliable, safer and lower cost physical plant.

The Value of Predictive Maintenance

We came across an excellent article published in England. The on-line publication, Process & Control Today has been around for a while, and is a good source for facility managers and engineers. Here's the link to "Managing Process and Equipment through Predictive Maintenance". When you finish reading it, call 303-718-1365, or link to a full-service source right here in the States, Martin Technical.

OSHA is Full of...Information

The government faces all kinds of battles...asked to do what it can't, or asked to stop doing what it is doing. One thing that does go well in our government, though, is the flow of information, particularly relating to workplace safety and regulation.

We are fond of this link to an OSHA page titled "Safety and Health Topics - Electrical." Lots of links to lots of resources and answering basic questions about what standards apply, what information is available, how to recognize hazards in the workplace, and some solutions to those problems.
