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 />
