4 risk-mitigation tactics for occupational disease in the oil & gas Industry

4 risk-mitigation tactics for occupational disease in the oil & gas Industry

Oil and gas workers routinely encounter heavy machinery, hazardous materials, and chemical byproducts – exposures that can put them at significant risk for occupational disease (OD). Managing these exposure risks is critical to prevent high-impact workers compensation claims, avoid heavy fines for violating Occupational Safety & Health Administration (OSHA) regulations, and, most importantly, keep employees safe. Scan our checklist of four key occupational hazards, along with risk-reduction tactics that can keep your company prepared.

1.  Hydrogen sulfide (H2S)

The risk: Hydrogen sulfide is a colorless, flammable gas that has a “rotten egg” smell. Depending on level of exposure, it can cause respiratory irritation or other complications that can lead to death.

The exposure: Hydrogen sulfide occurs naturally in crude petroleum and natural gas, and can collect in low-lying and enclosed, poorly ventilated areas.

Best practice: Active monitoring for hydrogen-sulfide gas (including personal wearables); routinely calibrated rig-detection systems; and safety training programs and emergency-management protocols for workers.

2.  Silica

The risk: Long-term, repeated exposure to respirable crystalline silica dust can cause silicosis, an incurable lung disease.

The exposure: Dust can be produced during processes that use sand, such as hydraulic fracturing. Potential exposure may be greatest for workers in loading, unloading, transporting, and storing sand.

Best practice: Sampling breathing zones to monitor exposure (especially in fracking operations); suppressing dust with water on roads and well sites; reducing distances between belt conveyors and blender hoppers; using centralized dust-control systems; and requiring workers to use NIOSH-approved respirators as needed.

3.  Volatile organic compounds (VOCs)

The risk: VOCs are emitted as vapors from naturally occurring components of crude oil. They include benzene, ethyl benzene, toluene, and zylene. High concentrations can create an oxygen-deficient environment, leading to loss of consciousness or death.

The exposure: Tasks with the greatest risk of airborne VOCs are tank gauging, tank sampling, and fluid transfer.

Best practice: Engineering controls such as remote or automatic gauging or sampling, blowdown valves, and so-called “thief hatch” pressure indicators; working upwind and away from open hatches; and using personal protective equipment.

4.  Noise

The risk: Hearing loss can occur from loud noises and explosions, or continuous high levels of noise.

The exposure: Oil and gas workers can be exposed to harmful noise levels for extended periods during equipment operation.

Best practice: Hearing conservation programs that protect hearing and equip workers with protection devices necessary to safeguard themselves; and assessing noise levels to meet OSHA standards of permissible exposure limit for noise at 90 dBA, as an eight-hour time-weighted average.
