hurricanes Dolly and Ike. RIMT and<br />
TIFMAS responders played essential<br />
roles in TFS and state response,<br />
providing hundreds of responders to fill<br />
critical roles.<br />
The year 2011 was a turning point for<br />
the agency. Texas experienced recordbreaking<br />
heat causing severe drought,<br />
setting the stage for the most destructive<br />
fire season in state history.<br />
The long battle began in mid-November<br />
2010 when freeze-cured grass and<br />
brush began to burn easily as cold,<br />
windy fronts moved in from the north.<br />
Over the course of the year, thousands<br />
of residents were evacuated across the<br />
state and 1,985 homes were destroyed.<br />
Texas experienced 31,453 wildfires that<br />
burned 4 million acres. In response TFS<br />
mobilized 16,690 personnel, 126 crews,<br />
244 dozers, 986 fire engines and 255<br />
aircraft to combat the fires. This includes<br />
1,718 responders and 432 fire engines<br />
mobilized under the RIMT and TIFMAS<br />
programs.<br />
Image taken by the Moderate Resolution Imaging Spectroradiometer<br />
(MODIS) on NASA's Aqua satellite, shows wildfires<br />
in Texas on April15, 2011 – the fires detected by MODIS<br />
are marked in red. Most of the fires shown in the image are<br />
larger than 10 thousand acres, and many have threatened<br />
communities.<br />
After the 2011 wildfire season, TFS<br />
launched the Texas Wildfire Risk<br />
Assessment Portal, a web-based tool<br />
to help homeowners and communities<br />
determine wildfire risks and how to<br />
best reduce hazards. Developed by TFS,<br />
TxWRAP was the first Web portal of its<br />
kind, with its foundation in wildfire risk<br />
assessment conducted by state forestry<br />
agencies across the Southern United<br />
States.<br />
For the past 100 years, emergency<br />
response has been a main objective<br />
for TFS. From fighting wildfires,<br />
equipping emergency responders with<br />
better training and equipment, giving<br />
landowners the tools needed to recognize<br />
wildfire risk and managing large-scale<br />
incidents — TFS has always been at the<br />
forefront, introducing new technologies<br />
and ways to better protect the great<br />
state of Texas. With a century of service<br />
complete, TFS looks to the future for<br />
more innovative and efficient ways to<br />
serve citizens and protect the state’s<br />
natural resources.<br />
DO YOU SMELL GAS? DEALING WITH<br />
DAMAGED GAS PIPELINES<br />
By Scott Finley, Texas811<br />
As a first responder, you’re familiar with<br />
9-1-1. But what’s your familiarity level with<br />
8-1-1?<br />
In Texas, 811 is the number to call to<br />
get underground utilities located before<br />
a proposed excavation. It’s the reason<br />
behind the small multi-colored flags stuck<br />
in the ground, or the splashes of spray paint<br />
on lawns, fields, streets and sidewalks.<br />
Texas811 is the state’s non-profit “call<br />
811 before you dig” entity, and is also the<br />
nation’s largest such one call center with<br />
approximately 1500 member utilities and<br />
municipalities. http://www.texas811.org<br />
Outgoing tickets issued by Texas811 to<br />
notify utilities of digs in 2014 topped 14<br />
million, and inbound tickets were 2.5<br />
million. The call to 811 is free, and so is the<br />
utility locating service. Not only that, it’s<br />
the law in Texas that such a call be made<br />
if ground is going to be broken at a depth<br />
of 16 inches or greater, but one call centers<br />
and utilities generally advise calling for any<br />
sort of digging, no matter the depth.<br />
No one is exempt from the law –<br />
contractors, professional excavators, utility<br />
companies, homeowners. And yet, in<br />
2014, the Railroad Commission of Texas<br />
recorded over 9,000 hits on gas/hazardous<br />
liquid lines in the state. (The RRC keeps<br />
tabs only on gas/hazardous liquid lines;<br />
individual utilities such as telecom, water<br />
municipalities, electrical, etc., keep their<br />
own records).<br />
Usually, striking a buried utility line results<br />
in nothing more than frustration – for both<br />
the utility involved and their customers. A<br />
cut water main or a telecommunications<br />
fiber optic line are cause for concern, but<br />
rarely lead to serious property damage,<br />
if any, and even more rarely to physical<br />
injury.<br />
Striking a buried electrical main or<br />
pressurized natural gas pipeline is another<br />
story. Any firefighter who has been in<br />
the business very long has responded to<br />
incidents where underground electricity<br />
has been hit, and the results are injury, fire,<br />
and many times electrocution fatalities.<br />
That’s something to bear in mind as you<br />
read this refresher from Texas811 and three<br />
of its member utilities on dealing with<br />
natural gas line strikes.<br />
The natural gas pipeline network in the<br />
United States spans 2.4 million miles.<br />
It is one of the safest forms of regulated<br />
transportation. Warning signs on pipeline<br />
rights of way show the product in the<br />
pipeline, the operator’s name and its<br />
emergency telephone number; however,<br />
the signs do not indicate a pipeline’s exact<br />
location or depth. Gas line operator/<br />
representatives can describe their natural<br />
gas pipeline facilities in your area, and you<br />
are encouraged to develop a good working<br />
relationship with your local company.<br />
You can locate natural gas and hazardous<br />
liquids transmission pipelines on the<br />
National Pipeline Mapping System. Go<br />
to http://www.npms.phmsa.dot.gov/. The<br />
NPMS does not make maps available to<br />
the public showing the location of natural<br />
gas distribution pipelines; however,<br />
government officials can request access to<br />
additional NPMS mapping data.<br />
Pipelines experience far fewer accidents<br />
than trucks, railroads, ships and airplanes –<br />
but accidents will happen.<br />
When a gas line is nicked, scraped or<br />
broken, regardless of smelling gas or not,<br />
the excavator must first call 911 to report it,<br />
and it must also be reported to the Railroad<br />
Commission of Texas (AFTER 911 and<br />
incident safety is secured).<br />
While first responders are on their way, a<br />
call must then be made to 811 to report the<br />
incident. This will generate what Texas811<br />
calls a “digup” ticket. This is an emergency<br />
ticket that then goes out to the utility in<br />
question, alerting them to what happened.<br />
First responders on the scene of a natural<br />
gas leak have a lot of work ahead of them.<br />
What follows is general information from<br />
Atmos Energy that should serve as a<br />
refresher for dealing with gas leaks which<br />
is applicable to all operators, as well as<br />
specifics related to Atmos and two more<br />
of Texas811’s largest gas utility members,<br />
CoServ and Texas Gas Service.<br />
Properties of Natural Gas<br />
Natural gas is:<br />
• composed primarily of methane (70% to<br />
98%), including small amounts of ethane,<br />
propane, butane and other gases<br />
• 40 percent lighter than air; it vents<br />
upward and dissipates rapidly into the air,<br />
but also can travel long distances to a point<br />
of ignition and can flash back<br />
• likely to travel the path of least resistance<br />
when below ground<br />
• flammable if the fuel-air mixture is from<br />
4 percent to 15 percent natural gas<br />
• odorless in its natural state<br />
• odorized with mercaptan in utility<br />
distribution pipelines to indicate a leak<br />
• not odorized in most transmission<br />
pipelines and gathering lines from<br />
producing wells<br />
