Hazards of static electricity PDF

Static electricity incidents have occurred in recent years which have highlighted concerns about explosion or fire while transferring vehicle fuels. These may indicate that changes taking place threaten the existing precautions for controlling these hazards. It is a well-known phenomenon that if two materials are rubbed together, static. static ignitions actually occur: If there is an ignition of leaked/leaking gas, in the absence of a known ignition source, given that the passage of natural gas inside a pipe creates static, the most probable cause of the ignition is that static electricity has arced to ground in the presence of a gaseous mixture Static Electricity - Hazards and Control - Dirk Smith, President -Ionix Gas Technologies 3 components to pipeline safety: 1. Damage prevention 2. System integrity and 3. Suppression of ignition sources. Suppression of static Electricity in gas pipe is one of the 3 necessary components to a comprehensive pipeline safety program

1.2 To evaluate the possibility of hazards from static electricity existing in an industrial locality or in a particular process, it is necessary to understand the causes and effects of the static electricity phenomenon. 1.3 Matter is composed of atoms that consist of negatively charged electrons circulating about a positively charged nucleus NFPA 77, Recommended Practice on Static Electricity (Ref. NFPA, 1 Batterymarch Park, Quincy, MA 02169) • Purpose - Provide assistance in controlling the hazards associated with the generation, accumulation, and discharge of static electricity • Contains: o A basic understanding of the nature of static electricity HAZARD OF STATIC ELECTRICITY For static electricity to be a hazard, four conditions must be met: There must be a means for a static charge to develop. Enough energy must build up to cause ignition. There must be a discharge of this energy (a spark). The spark must occur in an ignitable vapour or dust mixture Static electricity in one form or another is a phenomenon of nature and often results in electrostatic discharges that can cause fires and explosions. While expertise to reduce these hazards is based on research, in addition there is much industry experience upon which to base safety precautions when handling petroleum liquids Electrical Safety in the Workplace 8 A Little History of Electricity 600BC: Static electricity Thales, a Greek, found that when amber was rubbed with silk it attracted feathers and other light objects.

Controlling Static Electricity in Modern Buildings Graham Hearn Wolfson Electrostatics The problem of static electricity in commercial offices and stores is a relatively modern phenomenon. It represents an annoying source of painful electric shocks to both occupants and visitors and contributes to low morale amongst staff and workers. I Tips To Prevent Damage By Static Electricity. Here are some effective tips to make sure that risks caused by static electricity are minimized: Avoid wearing rubber-soled footwear: Rubber is an excellent insulator, and so wearing rubber-soled shoes may create a significant amount of static in your body The more turbulent the flow the more static electricity is produced. The Reynolds Number Ref 2 Sec 5-4 is a measure of turbulence within a pipe. The Critical Reynolds Number when flow changes from laminar to turbulent is about 2-3000 Reynolds Number Ref 2 Sec 5-4. Table 2 shows the Reynold electricity. Films are particularly prone to creating a static build up. Why is static a problem to me? • The discharge of static electricity may be only a small shock or build to the point that a lightning bolt-like spark will reach out and strike the operator, delivering life threatening voltage. • Static discharge is a spark however produced no significant readings of static electricity. Work undertaken independently by the three authors of this article has highlighted a number of factors influencing the levels of electrostatic hazard and these are discussed in this article. The influence on electrostatic ignition hazards due to th

Consequences of Static Electricity : 1-Electric arcs The factors which determine the potential of the electric discharge are: - Material - Humidity - Contact Pressure - Contact Area - Contact Times At least one of the material is an insulator. VESSEL EUROPE - Ionisers Presentation Static charge build-up is enhanced when the air is dry. So, static problems and effects are often noticed in dry air conditions. The air outside can be very dry when the weather is cold and dry. Indoors, central heating or air conditioning can give very dry conditions which promote static electricity. Heating warms the air and reduces its humidity

Remember that static electricity is an imbalance of electric charge between two objects. This imbalance has a definite polarity: one object is positive while the other is negative. This means that electrons rush in one direction when the two objects discharge through the path created by the neon gas inside the lamp Electrical Safety: Static Electricity. Most of us are familiar with static electricity. We all have walked across the rug and reached for the doorknob, only to have a spark jump from our hand to the knob. We have also seen the effects of static cling when our clothes cling together in the dryer Static Electricity • What is Static Electricity Static electricity occurs when there is a build up of electric charge on the surface of a material. It is called static electricity because the charges don't move. The electricity we use everyday involves moving charges. Static = Charge does not move or flow. 5 should lead to improved safety practices and evaluations of existing installations and procedures. When the narrow limits of static electricity ignition are properly understood, fire investigators should be encouraged to search more diligently for the true ignition sources in instances where static ignition is unlikely or impossible

product is a poor conductor of electricity and can become electrostatically charged. If sufficient charge is accumulated, ignition of flammable mixtures can occur. To reduce potential for static discharge, use proper bonding and grounding procedures. This liquid may accumulate static electricity when filling properly grounded containers These fires result from the buildup of static electricity. The insulating effect of the bed liner or carpet prevents the static charge generated by gasoline flowing into the container or other sources from grounding. The discharge of this buildup to the grounded gasoline dispenser nozzle may cause a spark and ignite the gasoline for static discharge, use proper bonding and grounding procedures. This liquid may accumulate static electricity when filling properly grounded containers. Static electricity accumulation may be significantly increased by the presence of small quantities of water or other contaminants. Material will float and may ignite on surface of water Electrical safety. Electricity can kill or severely injure people and cause damage to property. However, you can take simple precautions.
