The Occupational Health and Safety Administration (OSHA) enforces electrical safety regulations in the United States. Although OSHA has not adopted and does not mandate NFPA 70E compliance it possible you can still be cited for non-compliance?
OSHA’s authority to cite a company or an individual stems from the occupational Safety and Health Act in particular Section 5(a)(1) and 29 CFR 1910.2(g).
Section 5(a)(1) “The general Duty Clause” of the Occupational Health and Safety act, states that employers “shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”. This is the clause most cited by OSHA where unsafe work conditions are found to exist.
Another area where OSHA can fine companies or individuals for not abiding by national consensus standards. A consensus is a method by which an entire group of people can come to an agreement. The input and ideas of all participants are gathered and synthesized to arrive at a final decision acceptable to all.
Section 29 CFR 1910.2(g) states a “National consensus standard” means any standard or modification thereof which has been adopted and promulgated by a nationally recognized standards-producing organization under procedures whereby it can be determined that persons interested and affected by the scope or provisions of the standard have reached substantial agreement on its adoption”.
NFPA 70E is considered a national consensus standard and as such, non compliance leaves employers open for citation under Section 29 CFR 1910.2(g) if they are found not to be in compliance.
IRISS Electrical Maintenance Safety Devices help companies comply with NFPA 70E by ensuring closed cabinet fully energized inspections of critical switchgear. For more information on how IRISS can help you comply with OSHA requirements relating to energized inspections and maintenance of your critical assets visit our website – www.iriss.com.
Many people are not aware that the detector in an infrared camera actually only reads electromagnetic radiation it receives in a specific range of wavelengths. In order to display this in a useful reading the camera makes several calculations in order to convert the actual data to a temperature. The emissivity and transmissivity (sometimes depending on the camera manufacturer) have to be manually entered into the camera’s menu. if this value is entered incorrectly the actual temperature will be exponentially different (see Stefan-Boltzmann’s Law) than the displayed temperature. The old saying of “well as long as it is consistently wrong the change will be noted” is not entirely correct either, as the difference between phases will also be exponentially wrong. The error is going to be worse as the temperature rises – if the differential between the measured temperatures is significant then the displayed temperatures could be significantly different!
So that phase imbalance that looks like it is only a couple of degrees different could actually be upwards of 30 degrees! The visual setup of the camera could be the only other way of determining the severity of a potential defect. As anyone who has spent some time looking through a camera will tell you the visual component can be significantly altered (both to make things look better than they are as well as to show “elevated” differentials.) Depending on the level, span and range setup on the camera it would be very easy to miss a severe problem.
With this in mind it is easy to see why there are so many infrared problems that aren’t caught. In order to ensure that our customers “See What You’ve Been Missing”, all IRISS polymer based windows utilize the same grade and thickness of polymer, so that if you have correctly setup your camera for one IRISS window you can know without any doubt that it is “calibrated” for all IRISS windows. Our Fixed And Stable Transmission (FAST) is exactly what the name implies – unchanging! The ambient temperature outside, length of time in the field, relative humidity or barometric pressure have no effect on transmission rate and therefore no effect on your readings!
IRISS recently announced impressive testing results stemming from three of their products, the VPT and two of their new CAP-ENV IR Windows. (read the press release here).
IRISS’ VPT-100, CAP-ENV-6 and CAP-ENV-12 went under intense testing. The Arc flash test was performed in Poland, and the results were just down right impressive, the IR Windows were Arc Flash tested in line with the requirements of IEC62271-200 (1KV -50KV metal enclosed switchgear) at 6KV, 31.7kA, for 1.1 seconds, (was twice as long as standard tests). All the IRISS products successfully passed this extreme test.
Unlike Crystal Based IR windows the IRISS VPT and CAP-ENV Systems are the only visual and IR windows that are Impact resistant, maintain a fixed and stable IR transmission and offer the largest FOV (field of view) of any IR window available today. The IRISS’ VPT and CAP-ENV Series are by far the strongest most durable IR Window systems available on the market today.
IRISS Electrical Maintenance Safety Devices are used in a multitude of industries such as, Power Generation, Manufacturing, Data Centers, Maritime and switchgear OEMs. IRISS is continuously improving infrared window systems and developing innovative concepts in the electrical maintenance safety device market. This has led to the creation of the CAP-ENV System, an innovative industrial IR window that could withstand harsh environmental conditions, offering a durable transparent polymer lens that allows visual, UV, and infrared IR inspections to be completed whilst the panel remains in an enclosed and guarded condition.
