Safety and Environmental Protection
What the exam tests
Safety and environmental protection questions are practical: recognize the hazard, select the control, and know what must be contained or reported. Drilling sites combine heavy equipment, open holes, electricity, and silica dust.
Core hazards and controls
- Silica dust from air rotary and cutting: use water spray or foam, respiratory protection, and housekeeping rather than dry sweeping.
- Open wells and boreholes are fall and contamination hazards; cap or barricade them, and never leave a rig unattended with an open hole.
- Electrical: lockout/tagout before pump or control work; verify GFCI protection; treat submersible cable as energized until proven otherwise.
- Rigging and lifting: inspect slings, keep personnel out of the bight, and use tag lines.
- Confined spaces and trenches: do not enter an unsupported trench; pits and vaults may require confined-space procedures.
- Spills and drilling fluids: contain mud, fuel, and cuttings; use berms and absorbents; prevent discharge to storm drains or wetlands. Reportable releases go to NJDEP.
Worked example
An air rotary rig is drilling through sandstone on a windy day. Dust leaves the property. Stop, apply water injection at the bit, set up a dust-suppression curtain, and require respirators for the crew. Contain cuttings in a lined pit. Do not hose dust into the street: that turns an air-quality problem into a stormwater violation.
Traps
Wearing a dust mask only after the dust is visible. Treating a well pit as just a hole rather than a potential confined space. Leaving fuel cans and hydraulic hoses where a vehicle can strike them. Burying drilling cuttings on site without approval.
