Safety, Environmental Protection, and Site Restoration
This domain tests whether you can run a rig without hurting anyone or leaving a mess: silica dust, electrical and rigging hazards, spill control, wetland protection and restoring the site so the owner never knows you were there.
Hazards on a well site
- Crystalline silica from rock drilling is the signature exposure: use water or foam suppression, dust collection, and respiratory protection.
- Confined spaces - well pits, vaults and tanks - require testing and entry procedures, not a ladder and a guess.
- Electrical work needs lockout and qualified personnel; keep the rig and mast clear of overhead lines.
- Rigging and mast hazards: inspect cables and slings, control the swing zone, and never stand under a suspended load.
- Trenching, noise, and hydrogen sulfide in some formations round out the list.
Environmental protection
Contain fuel and hydraulic oil with absorbent and drip pans; keep drilling fluids and cuttings out of storm drains and wetlands; and remember that work inside the 100-ft buffer zone of a wetland, or the 200-ft riverfront area, may need Conservation Commission review under the Wetlands Protection Act. Any oil release reaching surface water is reportable in Massachusetts; larger land releases also carry reporting duties.
Restoration
Backfill and compact disturbed ground, restore topsoil, seed or pave, re-grade so water drains away from the wellhead, remove all debris and drums, and photograph the finished wellhead.
Worked example
A hydraulic hose fails and five gallons of oil soak the lawn 60 ft from a wetland. Stop work, shut the machine down, berm the area, absorb and excavate the contaminated soil into a labelled drum, and report the release as required because it occurred near and may reach surface water. Then restore the excavation and document it.
Traps
Dry-cutting rock; entering a pit without testing; leaving cuttings on site; and re-grading so the wellhead sits in a puddle.
