PPT-SM-TG 2016
When oil and gas workers open tank hatches to gauge or collect fluid samples on tanks that contain process fluids, they can be exposed to
2
Hydrocarbon gases and
vapors
Oxygen-deficient
atmospheres
Fires and explosions
PPT-SM-TG 2016
Opening tank or thief hatches can cause high concentrations of hydrocarbon gases and vapors to be released
3
Workers face serious health and safety risks when they gauge or sample tanks
PPT-SM-TG 2016
The gas and vapor concentrations that are released can be more than 10% of the lower explosive limit LEL
This increases the chances of a fire or explosion
4
PPT-SM-TG 2016
Exposure and fire and explosion risks can be different depending on factors, such asThe tank contents and operating conditionsIgnition sources
5
PPT-SM-TG 2016
Potential ignition sources includeStaticCell phonesSparks from tools or metal objectsOpen flamesNon-approved electrical equipment and devices

PPT-SM-TG 2016
Exposure to hydrocarbon gases and vaporscan affect a worker’s EyesLungsCentral nervous system
7
Even a brief exposure of 30 seconds or less could kill you
PPT-SM-TG 2016 8
Exposure can also have a narcotic effect and cause a worker to become dizzy, disorientated, and confused
Some hydrocarbons can also cause cancer
PPT-SM-TG 2016
There are many ways to prevent workers from being exposed to the hazards associated with tank gauging and sampling
9
PPT-SM-TG 2016
Employers must Conduct exposure and hazard assessmentsProvide trainingVerify sub-contractors are following work practices and procedures
10
PPT-SM-TG 2016
Employers should protect workers by using engineering controls such asRemote or automatic gauging and samplingBlowdown valvesTank sampling tapsThief hatch pressure indicators
11
PPT-SM-TG 2016 12
Workers should be trained on Hazard communication Lone worker policies Proper PPE and respiratory protection use Tank gauging work practices and
procedures Emergency response Use and limitations of toxic- or multi-gas
meters for oxygen, hydrogen sulfide, upper explosive limits, and carbon monoxide
PPT-SM-TG 2016 13
Workers must Follow your company’s hazard assessment
and established work practices and procedures
Attend hazard communication training
Be aware of potential ignition sources
Wear PPE as required
PPT-SM-TG 2016 14
PPE includes Flame retardant clothing Appropriate respiratory protection Impermeable gloves
PPT-SM-TG 2016
If you are unsure about any company policies or procedures or if you have any questions, stop the job and ask
Every worker has the right to stop work that is unsafe

PPT-SM-TG 2016
You face serious health and safety risks when you work on or near production and flowbacktanks and open a thief hatch
Follow your company’s work practices and wear the proper PPE
