When there is a danger of being exposed to an electric arc, personnel are advised to wear arc approved protective clothing. IEC 61482-2 is the overall standard that covers protective clothing against the thermal arc hazards of an electric arc. The IEC 61482-2 standard also covers various aspects of the garment design. This is a requirement for selling garments for arc flash protection within the EU. Garments complying with all of these requirements outlined under IEC 61482-2 should be marked with the IEC 61482-2 symbol as well as the level of protection it meets.
From minor control trips right down to compressor and transformer failures, harmonics can have an impact on every type of HVAC equipment. Surprisingly, harmonics is something that quite often can be overlooked. Harmonic currents and the electrical distribution system Harmonic currents flow in a circuit at multiples of the fundamental 60 hertz (Hz) frequency. For example, current flowing in a circuit at 180 Hz is the third harmonic (60 Hz multiplied by 3). These currents are not indicated on multimeters and therefore are usually not detected until unusual control and equipment problems start to happen. Comparing these current readings from … Continue reading
OK, so we know that PAT Testing is an essential part of any company’s Health & Safety Policy. But who is allowed to do it? Who is qualified to carry out PAT Testing? The IEE Code of Practice states that those carrying out inspection and testing must be competent to undertake the inspection and where appropriate, testing of electrical equipment and appliances. These competent individuals should have due regard to their own safety and that of others.

The law states that anyone who want to be a Portable Appliance Tester (PAT Tester)should be deemed to be competent at PAT Testing. To become a PAT tester you start by attentding a PAT Training course and gaining certification.
What is a PAT Tester? PAT tester is short for Portable Appliance Tester. A PAT Tester is an electrical safety testing device that tests any appliance in which a plug top is fitted. The idea behind the PAT test is to ensure that the electrical safety parameters i.e earth continuity/insulation resistance that were embedded by the product manufacturer have not been compromised while the equipment is in service.
In a nutshell, Portable Appliance Testing (PAT testing process) starts with observation of a portable appliance, followed by a formal visual inspection. The final step is a formal inspection by a person or competent to perform the testing. Step 1: Observation Simple observation is the first and very important of the PAT Testing process. For example, if while using a kettle in the staff canteen you to notice that the plug is cracked, you should immediately let the office manager/safety officer know. Step 2: Formal Visual Inspection All portable appliances in the workplace, or which are made available to the public for their use, … Continue reading
Gate, Ball and Butterfly Valves Valves, in a myriad of designs and sizes, are an integral part of piped systems that convey gases and liquids. They serve to control and regulate the flow of these substances in a safe, secure and prescribed manner. There are several types of valves that are in common use, including but not limited to the Gate, Ball and Butterfly valves. Maintaining such piped systems require the right type of lockout device that best suits the valve type, to ensure the safety of both the technicians and environment. It’s important to understand how these valves function, where and … Continue reading

It is an important task to store and locate lockout devices in their allotted places and track their usage across any given … Continue reading
The importance of effective and total energy isolation cannot be over-emphasised at every possible instance, given the heavy damage accidental re-energisation of equipment under maintenance continues to cause. Be it due to the lack of awareness, the absence of clear-cut processes and guidelines, or poor implementation of Lockout Tagout processes, it has been observed that de-energisation is a key contender for close attention, especially when working with automated and integrated processing systems. Energy Isolation in Complex Systems It is but natural for complex and integrated systems comprising a series of heavy machinery to be powered by multiple energy sources – … Continue reading
