20 Determining Material Needs Replace Submerged Meters & Regulators Gas Meters: Estimate # of gas meter changes within perimeter of flood regions Rule of Thumb up to 30% Regulators: Estimate # of I&C and Residential Regulators within Flood Regions Identify Pressure Areas affected Identify Large Volume Meter Sizes inside perimeter Consider Possible Site Rebuilds & Replacement Part Kits
21 Gas Restoration Safety & Procedures Review Service Technicians receive initial & daily Safety Tailboard reviews covering specific subjects: Flood Safety Mold Awareness Training Mercury Regulator Identification A&I Notifications (Gas Turn-ons) Warning Tag (Violation) Procedures Overheated Boiler Response Flood Restoration Procedures Gas Restoration Documentation
22 Safety Tailboard Preparation
23 Safety in Flooded Areas Wear hard hats, safety glasses, vest, gloves and other PPE when working in flooded areas. Expect floors and stairs to be oily and slippery. When ascending or descending stairs, hold the railing and step to one side. Do not go into basements where standing water, raw sewage or obvious electric hazards may exist. Treat all wiring, even telephone and cable, as live. Electricity and Water Do Not Mix - high potential for electric shock. Do not attempt to reconnect the electric supply to an appliance that has been exposed to water damage. Tetanus booster shot needed if not received within 10 years. Follow OSHA website to determine if additional shots needed (Hepatitis).
24 Tailboard Review Job Expectations
25 Gas Restoration Expectations for OEMs, Municipalities & Towns Damage Assessment: Track flooding conditions Assess Damage - bridge crossings, regulator stations, exposed main & other Company facilities Perimeter of Flooded Area: Estimate the number of customers affected by flood waters Field Command Centers: Secure suitable locations for restoration work Support severely damaged areas Work closely with local authorities (Police & FD) Establish ongoing communications mechanisms
26 OEM Employees Keeping Customers Safe in Hoboken
27 Partnership with OEMs Gas Restoration Process Join forces with Municipal Inspectors to establish a safe plan for assessing damaged structures and turning off gas facilities at the same time. Restoration activities will not begin until flood water has been cleared. Safely turn off gas facilities to ensure that flood water has not caused damage to utility/customer equipment and gas piping. Prior to the utility restoring gas service, Municipal Inspectors may expect to provide an inspection approval (where required) to determine that: Customer basements are cleared of water Electric facilities (electric panel, meter box) are verified for safety Following inspector approval, customers are expected to contact utility to restore gas after their home/building passes an inspection.
28 Post-Flood Inspections NJDCA supports the process shared between PSE&G and municipal inspectors for performing post-flood inspections and gas appliance restorations simultaneously. NJDCA provides inspector resources to assist municipalities not having enough staff to support postflood inspections.
29 Municipal Inspectors Partner with PSE&G
30 Gas Restoration Requirements When restoring gas to customers, PSE&G will establish that customer gas piping is not leaking, and may replace meters, service regulators and possibly regulator vent piping if they have been exposed to water. PSE&G will not restore gas to water heaters if controls have been affected by flood waters. Flooded units must be replaced. PSE&G s restoration policy for gas fired furnaces & boilers requires that all gas controls, control system parts, and electrical parts that have been underwater must be replaced before the unit may be safely operated. Replacement of the entire unit may be required if deemed necessary by individual circumstances on a case-by-case basis.
31 Explosion/Injury Risks Boilers & Furnaces Heating controls exposed to flood water can fail after being dried and placed back in operation. Any controls exposed to flood water must always be replaced.
32 What is an Overheated Boiler? Overheated Boiler : Heating unit reaches an exceedingly high temperature and pressure, and will not shut off. This condition, a.k.a. Runaway Boiler, is considered unsafe and very hazardous to emergency responders and building occupants. This condition is primarily caused by coincidental failures of redundant safety controls that maintain safe temperature, pressure, gas supply, and water supply. Previous boiler failure incidents occurred when safety controls failed to operate as designed due to mechanical failure (i.e., aquastat shorting out, damaged wiring, or failed gas valve) or human intervention.
33 Service Technician Performs Safety Inspection on Customer Boiler
34 Hazard Description When boilers or furnaces experience an overheated condition, catastrophic damage to the heating unit, safety controls and components is likely. PSE&G treats this situation with the highest degree of emergency response - similar to an inside gas leak with open air gas readings of 1% or greater. First Responders are expected to evacuate all occupants, and keep the public a safe distance away from the building.
35 Provide restoration update for community Describe steps required to restore customers OEM Coordination Town Hall Meetings
36 Exit Strategy for Customer Support Work with OEMs, towns and municipalities to plan an Exit Strategy after the majority of customers have been restored and local Command Centers have been discontinued. Exit Strategy includes: Establishing contact information and designated responsibilities to support customers who have had restoration delayed due to repairs or other circumstances.
