The principles of Protective Multiple Earthing (PME) 19/12/2017 29 comments As the majority of low voltage supplies to both new and existing electrical installations are connected to a PME earthing terminal this article discusses the operating characteristics of this particular supply arrangement which in its entirety is known as a TN-C-S system As shown in Fig 1 in a PME arrangement the

With the launch and success of Nintendo Switch Nintendo showed the world the value of user-centered design in gaming Unlike their previous product Wii 2 Switch is easy to set up and use and it solves a problem many users might not have even realized they had: how to bridge the gap between home and on-the-go play The Switch is a 6 2-inch capacitive HD touchscreen sandwiched between a

While many construction site risks can be eliminated or reduced (some at the design stage) many residual risks can only be dealt with by the use of PPE For example head protection will be required on most construction sites The Personal Protective Equipment Regulations 2002 and the Personal Protective Equipment at Work Regulations 1992 (PPE Regulations) give the main requirements as to

• Identify facility design work practices and PPE required for work at the BSL2/ABSL2 level • Employ standard precautions for BSL2 agents while handling these materials • Properly use a biological safety cabinet (BSC) • Demonstrate proper clean -up procedure for an infectious material (BSL2) spill • Identify the role of the Institutional Biosafety Committee (IBC

Personal Protective Equipment use The use of personal protective equipment should only be contemplated as a viable control measure when consideration of all of the other methods of hazard control has occurred However it is recognised that there are many occasions where there is either no alternative other than to use personal protective equipment or where personal protective equipment
