Tank Gauging
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 Hydrocarbon gases and vapors Oxygendeficient atmospheres Fires and explosions 2
Opening tank or thief hatches can cause high concentrations of hydrocarbon gases and vapors to be released Workers face serious health and safety risks when they gauge or sample tanks 3
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
Exposure and fire and explosion risks can be different depending on factors, such as The tank contents and operating conditions Ignition sources 5
Potential ignition sources include Static Cell phones Sparks from tools or metal objects Open flames Non-approved electrical equipment and devices 6
Exposure to hydrocarbon gases and vapors can affect a worker s Eyes Lungs Central nervous system Even a brief exposure of 30 seconds or less could kill you 7
Exposure can also have a narcotic effect and cause a worker to become dizzy, disorientated, and confused Some hydrocarbons can also cause cancer 8
There are many ways to prevent workers from being exposed to the hazards associated with tank gauging and sampling 9
Employers must Conduct exposure and hazard assessments Provide training Verify sub-contractors are following work practices and procedures 10
Employers should protect workers by using engineering controls such as Remote or automatic gauging and sampling Blowdown valves Tank sampling taps Thief hatch pressure indicators 11
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 12
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 13
PPE includes Flame retardant clothing Appropriate respiratory protection Impermeable gloves 14
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 15
You face serious health and safety risks when you work on or near production and flowback tanks and open a thief hatch Follow your company s work practices and wear the proper PPE 16
