Construction Safety
Published in W. David Yates, Safety Professional’s Reference and Study Guide, 2020
The main hazard from static electricity is the creation of sparks in an explosive or flammable atmosphere. The danger is greatest when flammable liquids are being poured or transferred. Static electricity can also build up to where injury or even death can result from electrical shock.
C&G Unit 303: Electrical installations: Fault diagnosis and rectification
Published in Trevor Linsley, Advanced Electrical Installation Work, 2019
Static electricity is a voltage charge which builds up to many thousands of volts between two surfaces when they rub together. A dangerous situation occurs when the static charge has built up to a potential capable of striking an arc through the airgap separating the two surfaces.

It is common practice in stationary sampling to mount measurement devices away from walls, and adopting a similar approach might be beneficial for personal sampling with the UNC sampler. In working environments where the workers wear helmets, one could mount the samplers on top of the helmet, ensuring air flows in all directions and removing the rubbing of the clip holder, and possibly reducing the build-up of static electricity. Ideally, grounding could be arranged to avoid static electricity. Positioning of the UNC sampler for personal sampling needs to be studied further. The UNC sampler also needs to be studied under conditions in which it is subject to bursts of high occupational exposure.

Static electricity is commonly found in daily life and can cause accumulation of dust, skin diseases, heart rate abnormalities and even premature heartbeats, which seriously threaten human health (Du et al., 2017; Wang et al., 2017). Polyester fiber, such as PET, has a wide range of applications due to its excellent physical properties (high strength, well elasticity and abrasion resistance), chemical properties (resistance to oxidation and corrosion) and low cost. However, polyester fibers are extremely deficient in hydrophilic groups and are prone to static electricity (Amass et al., 2015). Therefore, the antistatic finishing of polyester fiber has become a rigorous problem to be solved.

The Triboelectric nanogenerator (TENG) is a sensor based on the IoT system. TENGs are a unique type of technology that can transform mechanical energy in the environment into electrical energy. It has become a hotspot in the energy industry because of its broad variety of energy sources, high energy conversion efficiency, and broad application range. It can transmit the data in the form of a signal to extract the critical data efficiently. Normally, the signals from the triboelectric sensor are collected by the MCU Microcontroller Unit then the signals get transmitted out of it. The triboelectric recognition method is a sensing technology that identifies objects based on their unique triboelectric properties. It is a touch-based method that can detect and recognize a wide range of materials and shapes by producing a triboelectric charge on the object’s surface when it touches another surface. The triboelectric recognition method has many potential applications in various fields, such as medical devices, robotics, security systems, and environmental monitoring. It provides a non-invasive and non-destructive way of detecting and recognizing objects, making it a promising technology for future development. Triboelectricity is not used directly to decrease the risk of patients. While it refers to the generation of an electric charge through the contact and separation of materials, it is not directly related to patient safety. To reduce this risk, measures can be taken to manage static electricity buildup, such as using antistatic materials, maintaining proper humidity levels, and grounding equipment. This application of electrostatic principles helps improve patient safety. Further, it is important to note that this is not the same as using the principle of triboelectricity directly. Thus, TENG involves different communication formats, digital to analog and analog to digital. Another communication interface is also used by increasing energy consumption at the end of the sensor to reduce this effect coupling is made based on electromagnetic coupling; thus, transmitting the digital signal of TENG to the optical communication infrastructure provides an advantage to the system. It isn’t easy to load the signals produced by the TENG-based sensor to the optical communication directly and efficiently. Therefore OC is considered the immunity to Electromagnetic Interference EMI for transmitting a high-speed signal with a very low level of dispersion and for the increased level of distance (Schenkel 1995).
