Two Trains Passing in the Mountains Experience a Natural Gas Explosion

On June 3, 1989 in RussiaΓÇÖs Ural Mountains near the town of Ufa, a natural gas pipeline experienced a significant drop in pressure indicating a possible gas leak. In an effort to keep the pressure up, pipeline workers increased the flow of natural gas to the pipeline allowing the natural gas to leak and spread into the surrounding area. The natural gas settled in a low area close to nearby a Trans-Siberian Railway. As the natural gas began to settle in the low area, two trains approached each other from opposing directions on the rail tracks passing each other near the settled natural gas. As the two trains passed, the settled natural gas ignited causing a massive explosion including a fireball and flames that spread one mile from the source. The force of the explosion incinerated hundreds of trees instantly and knocked several train cars off the tracks. Due to the severity of the incident, it is not possible to determine the exact amount of lives lost. However, the best estimates were just over 500 lives lost and numerous individuals suffered severe burns requiring helicopter transport to local hospitals for treatment.

2014 Manhattan Gas Explosion (NTSB Coverage)

NTSB Meeting Covering the 3/12/2014 New York City, NY East Harlem District of Manhattan Gas Explosion On June 9, 2015, the NTSB (National Transportation Safety Board) held a meeting to discuss the findings and final rulings on the 3/12/2014 New York City, NY East Harlem District of Manhattan Gas Explosion. The final ruling is expected to be released sometime in July. The NTSB determined two factors contributing to the probable cause of the incident: Failure of a defective fuse joint at a service tee A breach in the adjacent sewer line that allowed groundwater and soil to flow into the sewer that was left unrepaired since at least 2006, resulting in a loss of support for the gas main, which caused the line to sag; thereby overstressing the defective fusion joint Recommendations determined through the NTSB meeting outline and follow industry best practices for integrity management, quality work procedures performed by qualified individuals, emergency planning, strategic isolation valve placement, and thorough audit processes on a 5-year basis.

Safety First: OSHA Heat App

Summer is here and so are the temperatures! Safety must come first when working outside during the summertime to avoid heat-related illnesses. To assist with this, OSHA (Occupational Safety and Health Administration) has developed and released an OSHA Heat App for your mobile device! The OSHA Heat App calculates the current heat index and risk level of a particular area or job site using the current temperature and humidity level. Based on the heat index and risk level, the OSHA Heat App provides a Precautions button to help reduce the risk of heat-related illnesses and accidents. By clicking the Precautions button, the user will receive reminders for such things as rest breaks and fluid intake. The OSHA Heat App is available in English and Spanish for Andriods or iPhones. To download your OSHA Heat App today, please visit: https://www.osha.gov/SLTC/heatillness/heat_index/heat_app.html.

Industry Evolution: Training is Key in OQ NPRM

In this edition of the EWN Educational Series on the Industry Evolution, EWN reviews the significant expansion of mandatory training requirements proposed by PHMSA. The following information summarizes PHMSAΓÇÖs proposed regulatory changes, guidance provided to PHMSA by the Pipeline Advisory Committees (PACs), and comments regarding the impact of these proposed changes on the industry. Mandatory OQ Training Under current regulations, an individual may rely on his/her experience to be evaluated and qualified to perform a covered task, and training is only required ΓÇ£as appropriate.ΓÇ¥ Specific documentation of training is not currently a qualification or program recordkeeping requirement. PHMSA previously issued guidance on training expectations via FAQs found at: https://primis.phmsa.dot.gov/oq/faqs.htm#4 Current Regulation: 49 CFR 192.805(h) and 195.505(h). After December 16, 2004, provide training, as appropriate, to ensure that individuals performing covered tasks have the necessary knowledge and skills to perform the tasks in a manner that ensures the safe operation of pipeline facilities; The pending OQ NPRM is a significant shift to the current OQ Rule by mandating actual documented training, in addition to evaluations, for a covered task prior to an individual being allowed to perform that covered task (except when doing so under span-of-control). This requirement includes being trained […]
