NJ Emergency Response Program
New Jersey maintains 576 Fire Stations (paid/volunteer) that serve 566 municipalities.
Over the years, NJ has maintained a proactive position by ensuring that Emergency Responders are trained and well prepared to handle all types of emergencies.
The NJ Administrative Code (NJAC) requires utilities to offer training and establish liaison with FD’s, OEM’s and Public Officials for handling gas pipeline emergencies.
According to the NJAC, energy providers are expected to conduct an annual drill covering a transmission pipeline emergency.
NJ Emergency Response Program
Utility Hazard Awareness Program was developed by a state-wide team in 2008: NJ Utility Representatives Propane Representative AEGIS Loss Prevention Services State Fire Marshalls
Program was designed to provide emergency response officers with utility hazard awareness and safety aspects for integration into SOP’s for a coordinated approach to incidents. Fire, Police, EMT & OEM groups
NJ Emergency Response Program
Program Objective: Provide information about utility hazards and
safety considerations for emergency responders. Provide opportunity for different emergency
agencies to discuss their emergency response SOP’s and coordination prior to an event.
Aid in development and enhancement of SOP’s. Recommend an approach consistent with National
Incident Management System (NIMS) for coordination with utilities and facility owners.

Damage Prevention
Overall, gas pipeline damages are declining annually.
No one area of focus is attributed to this positive trend.
We find that pipeline operators need to do many things to promote this continuous improvement.
Damage Prevention
Explosions can occur, regardless of pipe size and pressure.
Most damage incidents have been involved with service pipe on customer property.
Police Awareness for Markouts
We ask Police to report occurrences when they find street construction areas that are not marked out.
We make it clear that this action will help the community by preventing damages, which will, in turn, eliminate additional trips by emergency responders.

• If a gas concentration is above 15%, an imminent danger exists when venting.
• As gas dissipates, it will pass through the Explosive Range before reaching 0%.
CGI Calibration for Accuracy
Combustible Gas Indicators (CGI) must be calibrated according to manufacturer
specifications.
The CGI is calibrated using a specific gas. If any gas other than methane is used, CGI sensitivity and response may not directly correspond to the actual natural gas level being measured.
CGI readings are only accurate for the type of gas used to calibrate the CGI. Adjustments to readings need to be made for all other gases to obtain the actual flammable level.
Some CGI manufacturers provide a table with correction factors used to obtain a more accurate reading if the gas being tested is not the gas used to calibrate the CGI.
Gas Leak Detection Equipment
During FD training, PSE&G reviews the need to calibrate gas detection equipment periodically.
Bascom-Turner Gas Sentry CGI’s equipped for CH4 and CO are used by over 750 service technicians (first responders).
Instruments at PSE&G are automatically calibrated in a docking station and tracked on a monthly basis.
Gas Leak Detection Equipment
PSE&G will allow access to automatic calibration equipment for any FD that purchases Bascom-Turner gas detection instruments.
For periodic calibrations, PSE&G will allow access to any assigned Gas District locations during normal business hours.

Gas Leak Migration
Gas leak present at house 516
Possible migration at all neighboring houses
• Use full personal protective equipment
• Always assume there are multiple gas leaks – you must verify that the area is clear of gas. Check entire area, including across the street, surrounding buildings & subsurface structures.
• Use properly calibrated gas detection equipment
• Ground conditions can impact gas migration and leak pattern
• Always coordinate actions with the utility
• Follow action levels, communication, & gas readings
• Once gas is controlled and sources of ignition eliminated, use care in airing out buildings (may bring into explosive range)
• Some gas service lines have excess flow valves (EFV’s) for protection
Gas Migration Considerations
Natural Gas Do’s & Don’ts
• Notify the gas company immediately while enroute - utilize the gas company’s expertise
• Treat all gas leaks as potentially hazardous • When in doubt, evacuate structures and/or surroundings• Look for multiple gas leaks even if the gas is burning• Secure affected areas by doing a complete hazard assessment
of area• Use only properly calibrated leak detection equipment – CGI
must be turned on in a non-gaseous environment• Establish detection equipment action levels (evacuation
thresholds)• Use only intrinsically safe communication devices and other
electrically operated equipment• Only shut off above-ground meter valves
Do:
• Park over manhole or valve covers, storm drains or too close to structures
• Park in front or downwind of emergency locations• Use open flames (flares, smoking, other sources) • Operate any in-ground or underground valves• Operate doorbells, light switches, other electrical devices
or ignition sources (pagers, cell phones, radios) • Turn off venting relief valves• Extinguish gas fires until fuel sources have been secured• Turn on gas valves• Shut off gas service to industrial facilities without
knowledge of its effect - this can cause additional damage
Natural Gas Do’s & Don’ts
Don’t:
Meter Valve Shut-offs
Valve in on position Valve in off position
Never force an above ground
gas meter valve in the wrong
direction!
Match the wings!
Carbon Monoxide (CO)
Carbon Monoxide is a product of “Incomplete Combustion”.
CH4 + 2O2 === CO2 + 2H2O(v)
Consider the chemical formula for Complete Combustion. Carbon Monoxide (CO) is formed when not enough air (O2) is available to create carbon dioxide (CO2).
1 cu.ft.gas
+ 2 cu.ft.air
1 cu.ft.carbondioxide

CO Characteristics
Colorless Odorless Tasteless Nonirritating
Invisible to humans
Lighter than air Highly Toxic in Very
Small Concentrations Explosive Range
12% to 74% “Backdraft”
experienced by firefighters
CO Warning SignsNoticeable Conditions:
Aldehydes – an alcohol odor may accompany CO in the process
Condensation – may be visible on walls or windows in affected area
Dead Houseplants – due to absence of oxygen
Lethargic Pets – small pets “get tired” quickly from effects of CO, due to a higher breathing rate.
Carboxyhemoglobin (COHb)
“Carboxyhemoglobin” is the poisoning of the blood due to effects from carbon monoxide (CO)
In the process, CO is transferred to blood via lungs CO bonds with hemoglobin in blood CO reduces blood’s ability to transport O2
throughout the body CO is 200x more attracted to blood hemoglobin than
O2 To reverse effects from CO poisoning, need 200
parts O2 to replace one part CO
Progressive Flu-Like Symptoms
Low/Medium Exposure Symptoms: Headache Dizziness Fatigue Nausea Poor Coordination Confusion
High Exposure Symptoms: Severe Headache Shortness of
Breath Chest Pains Vomiting Red Eyes Unconsciousness Coma Death
Increased Susceptibility to CO
Pregnant Mothers – fetus experiences effects before the mother
Infants – due to higher respiration rate
Heart Condition Cases –the heart is the first major organ to be affected
Smokers – some CO may already be in blood prior to a significant exposure
1 HOUR EXPOSURE LIMITS & SYMPTOMS
200 ppm (15%) slight headache
400 ppm (30%) headache drowsiness nausea
600 ppm (45%) coma brain damage
Breathing Fresh Air
High Flow Oxygen –administered on site by emergency responders (EMS)
Hyperbaric Chamber –administered in hospitals
Treatment for CO Poisoning
Emergency Responder Training Implementation
PSE&G uses supervisors from operations and support areas who are experienced and received Emergency Response Training.
Supervisors from 4 operating areas are designated to provide training to emergency responders in the service territory.
PSE&G sends annual training invitations to Fire Chiefs, Mayors, Business Administrators & Offices of Emergency Management.
Municipal representatives are invited every 2 years.
Emergency Responder Training Implementation
PSE&G provides attendees with packages containing presentations slides, damage prevention brochures, “What You Need To Know About Safety” info and CD’s with supporting resources and training materials.
PSE&G tracks training participants with a sign-in sheet, and a dated attendance list is prepared for future use.
PSE&G hand delivers presentation material packages to FD’s and municipalities that were not in attendance.

Emergency Responder Training Implementation
PSE&G normally provides training to a collection of emergency response groups assembled at a Company facility.
If requested, PSE&G will also provide the same training at FD and municipal locations.
Attendance is monitored very closely, and every effort is made to achieve full participation from all emergency response groups.
Municipal Drills & Meetings
Since the San Bruno (CA) incident, Municipalities and Fire Departments have become much more responsive to meeting with gas operators to discuss emergency response.
Various municipalities may invite PSE&G to participate in local discussions or tabletop drills to address how utilities would respond to various types of incidents.
Recent tabletop drills with the State focused on response to damage caused by potential natural disasters or terrorist activities.
NJ Transmission Pipeline Operator Requirements
Due to PHMSA (DOT) & NJ Administrative Code requirements, Utilities & Emergency Responders in NJ have been well prepared to handle gas transmission facility incidents.
Each public utility operator is required to meet on an annual basis with appropriate fire, police, and other public officials of each municipality through which its transmission pipeline traverses.
Operators are required to maintain records of outreach meetings with local officials, including attendance and the basic topics covered.
Transmission OperatorOutreach Meetings
To meet NJAC requirements and DOT (PHMSA) Code Rule 192.615, the PSE&G Pipeline Integrity Manager conducts face-to-face meetings with fire, police, and public officials from each municipality having gas transmission pipelines in their jurisdictional area.
The group reviews facility maps, recent system changes and critical valve locations for emergency shutdown.
PSE&G shares copies of transmission pipeline maps with top emergency response officials.
PSE&G ensures that each emergency response group understands the hazards when responding to a gas transmission pipeline incident.
