Walkaround Inspection

A legal finding that two companies share employer responsibilities over the same workers. In field service, this can mean a client company is liable for your crew's wages, hours, or working conditions. Subcontractors should review contracts carefully to avoid unintended joint employer exposure.

A range of conditions caused by overexposure to heat, from heat cramps and exhaustion to life-threatening heat stroke. Subcontractors working outdoor or industrial sites must monitor crew members and follow site heat stress protocols. Failing to manage heat illness risks can trigger regulatory violations and project shutdowns.

A licensed physician who reviews and verifies workplace drug test results before they are reported to an employer. Subcontractors must use an MRO-approved process to meet site access and compliance requirements. Failed or unverified MRO results can pull workers from the field immediately.

A regulatory standard requiring subcontractors to limit worker exposure to airborne silica dust on worksites. Common in drilling, sandblasting, and concrete cutting operations. Requires action plans, air monitoring, and respirator programmes for affected crews.

Human-caused ground tremors triggered by oilfield operations like hydraulic fracturing or wastewater disposal. Regulators may issue stop-work orders, directly halting your field operations. Subcontractors should track local seismic thresholds, as exceeding them can suspend permits and delay project timelines.

The length of time a work permit remains valid before requiring renewal or reissuance. Short permit durability can stall field crews and create costly downtime between tasks. Subcontractors should confirm permit expiry windows before scheduling labour and equipment.
