  • Carbon Dioxide (CO2) Leak in Soda Machines

    Carbon dioxide, also known as CO2, is a very well known gas type but not everyone knows how deadly it is. Most people know it as a gas that humans exhale but commercially, it is manufactured and shipped as a liquefied compressed gas or is used as dry ice in its solid form. A common use of CO2 gas is in soda fountain machines to carbonate soft drinks by pressurizing the CO2 ...

  • GE Leakwise Application Notes: Leak Detection by Groundwater Monitoring

    Risks of Groundwater Contamination Hydrocarbon leakage, from Underground Storage Tanks (USTs) and from the bottoms of above ground tanks, can seep into the groundwater, where it forms a floating oil sheen, or a thick oil layer. This layer, if left undetected, ...

  • Detection and Location of Leaks in Geomembrane Liners Using an Electrical Method: Case Histories

    ABSTRACT A field-proven electrical technique, developed at Southwest Research Institute, San Antonio, Texas, is commercially available to detect and locate leaks in geomembrane liners. The electrical technique is used to inspect 100% of the geomembrane material that is covered by a conducting liquid. A voltage applied across the liner produces a uniform electrical potential distribution in ...

  • Enhanced Geomembrane CQA through proper application of geomembrane leak location surveys

    Abstract Historically, geomembrane construction quality assurance (CQA) has focused on destructive testing of welded seams to verify seam strength and integrity. Paradoxically, seams are not subject to significant stress and practically never fail in service, while holes and construction damage in the geomembrane are a much more widespread problem. The historical approach fails to evaluate ...

  • Early Ethylene Glycol Leak Detection in Power Plant Steam Condensate Is Essential

    Fossil fuel and nuclear power plants use heat exchangers to condense process steam back into liquid form. A heat exchanger works by transferring heat from one medium (steam) to another medium (air, water, or ethylene glycol). Many newer, closed cooling water system, power plants use ethylene glycol use ethylene glycol (C2 H6 O2 ) as a heat transfer fluid because of its high-heat transfer ...

  • Build your pond to last with a liquid liner

    Build a pond without providing proper sealing and you'll probably be watching your money getting washed down the drain. Pond cracks, pond holes and pond leaks can be a persistent and costly problem so heading them off before they start in the construction process is a very good idea. That means paying particular attention to lining your ...

  • Chemical storage buildings isolate hazardous liquids and minimize damage from spills

    The improper storage of corrosives and flammable liquids is the leading cause of spills that can result in damage to facilities and impact worker safety. One of the most effective practices to help minimize damage from chemical spills is to isolate the various chemical hazards. Since knowledge of chemical compatibility is critical, it is important to understand that there are two major types of ...

  • GE Leakwise Application Notes: Leak Detection for a Floating Roof Oil Storage Tank

    Oil Storage Tank with a Floating Roof Floating Roof Drainage Operation Stormwater accumulated on a concave floating roof of an oil storage tank may affect its floatation, making it necessary to immediately drain the water. This is usually done through a flexible pipe, running from the floating roof down the tank, with an outlet above the ground near the bottom of the tank. ...

  • Why the use of a CO2 monitor may not be the best solution for protecting workers against leaks from beverage dispensing systems in the fast food industry

    Carbon Dioxide (CO2) is the primary compressed gas used for dispensing beverages at fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, it creates a very unsafe environment for employees because it lowers the concentration of breathable oxygen.  History seems to repeat itself all too often while ...

  • Specifying allowable leakage rates

    Introduction Allowable Leakage Rates or Action Leakage Rates (ALRs) are specified for installed geomembranes to quantify the maximum allowable liquid leakage. If the ALR is exceeded, corrective action must be taken to reduce the leakage rate below the set limit. To lower the leakage, the holes in the geomembrane are located and repaired. In some cases, the ALR is set so low that, ...

  • The Second Line of Defence

    The environment is at the top of everyone’s agenda. Oil and related products can be a threat to the natural world when they leak, causing major environmental consequences that kill wildlife, pollute water and spoil agricultural land. It takes both great expense and time to clean up a spill, so a second layer of protection is required as a safety net. The first layer of protection present at ...

  • Enhanced LDAR in the chemical industry

    As a result of recent leak detection and repair (LDAR) audits and the associated issues (as described in the Winter 2009 issue of Environmental Quarterly), EPA is initiating enhanced LDAR programs as part of the most recent consent decrees.1 The enhanced LDAR programs for chemical facilities are more stringent than the enhanced LDAR previously required for the petroleum refining industry. ...

  • LDAR deficiencies lead to enhanced requirements

    Leak detection and repair (LDAR) programs are required as part of the standards established in 40 Code of Federal Regulations (CFR) 60 (NSPS), 40 CFR 61 (NESHAP), 40 CFR 63 (MACT), and 40 CFR 264 (Hazardous Waste Handling). An LDAR program is a facility’s system of procedures used to locate and repair leaking components (e.g., valves, pumps, connectors, compressors, and agitators) to ...

  • Monitoring flammable gas in boiler houses

    The most common fuels in use for space and water heating are Oil, Natural Gas and Liquid Petroleum Gas (LPG). By far the most popular, clean and cost effective solutions are utilising Natural Gas or LPG. The traditional safety measure derived from the time of oil fired boiler houses is the use of a fusible link placed above the each boiler. The fusible link is intended to melt if it becomes ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

  • Gas Detection in Public Swimming Pool Facilities

    Recreational facilities’ indoor swimming pools provide a venue for exercise, competition and fun for all ages as patrons splash, swim, dive and float around in the crystal clear water. To keep the water fit to swim in requires a disinfectant maintenance program commonly using Chlorine, or Chlorine and Ozone. Chlorine is a powerful, corrosive disinfectant and in both gas and liquid forms it ...
