Extraction","sector":"23","jobZone":2,"jobZoneInferred":false},"framework":{"version":"v.26.05","description":"","contextCovered":"This framework covers explosives loading, detonation, fuse rigging, blast-site safety, drilling instruction, and regulatory recordkeeping in construction, quarry, and demolition environments calibrated to Job Zone 2 preparation and experience levels.","levels":{"emerging":{"label":"Emerging","statements":["Blast area boundaries — identify and mark using safety cones under direct supervisor guidance at a construction or quarry site.","Explosive charge types — recognize and distinguish among dynamite, ammonium nitrate, and black powder when following written handling protocols.","Blast hole depths — measure using weighted tape measures under close supervision at a drill site.","Safety signals — perform worker-clearance signaling procedures following established site protocols before any detonation.","Explosive materials records — assist in compiling gun and explosives logs under direction to meet local and federal compliance requirements.","Tamping and packing procedures — follow step-by-step instructions to shovel drill cuttings and compact explosive charges in blast holes.","Personal protective equipment — select and don required PPE correctly before entering any blast zone on a supervised work site.","Delaying fuse lengths — cut and handle specified fuse segments under supervision while observing timed-sequence safety requirements.","Drilling pattern markings — read and interpret charge-hole location diagrams issued by a lead blaster on a surface blasting site.","Active listening and instruction-following — receive and confirm verbal safety directives from supervisors in a loud, high-hazard blasting environment."]},"developing":{"label":"Developing","statements":["Blast area assessments — examine charge locations and surrounding conditions routinely to verify compliance with safety laws at excavation or demolition sites.","Explosive charge placement — insert and position charges in blast holes with reduced oversight, adjusting packing methods to match site soil or rock conditions.","Delaying fuse patterns — tie specified fuse lengths into timed sequences independently to achieve planned explosion intervals on a multi-hole blast.","Hole-depth measurements — measure and record drilled blast hole depths using weighted tape measures, flagging discrepancies for corrective action.","Explosive loading calculations — apply basic mathematics to determine appropriate charge quantities based on assessed material type and blast area dimensions.","Safety-zone coordination — set safety cones, monitor worker positions, and issue clearance signals without prompting before each detonation event.","Explosives and gun records — compile and maintain compliant logs in spreadsheet or office software in accordance with local and federal regulations.","Detonation operations — detonate explosive charges to loosen or displace earth, rock, or structures, following site-specific shot plans with moderate supervision.","Drilling instructions — mark charge-hole patterns and depths on site drawings and communicate drilling instructions clearly to drill operators.","Hazard monitoring — observe blast site conditions during and after detonation, identifying misfires or unexpected outcomes and reporting them to the shift supervisor."]},"proficient":{"label":"Proficient","statements":["Blast design evaluation — autonomously assess blast areas for complex terrain, structure proximity, and material variability to determine optimal explosive types and charge amounts.","Non-routine misfire response — diagnose and safely resolve misfired charges using established protocols, exercising independent judgment in high-pressure demolition or quarry environments.","Multi-sequence fuse architecture — engineer and tie intricate delay-fuse patterns to coordinate precise multi-stage detonation sequences for large-scale excavation or demolition projects.","Charge placement in confined environments — execute explosive loading in structurally complex or restricted spaces, adapting packing and tamping techniques to non-standard conditions.","Regulatory compliance management — independently compile, audit, and submit gun and explosives records to ensure full compliance with all applicable local and federal statutes.","Drilling program direction — develop detailed drilling instructions, specifying hole patterns, angles, and depths for drill crews based on site geological assessments.","CAD and GIS tool application — use computer-aided design and geographic information system software to model blast zones, optimize shot plans, and document spatial data.","Critical problem-solving under time pressure — evaluate unexpected geological, structural, or environmental conditions mid-operation and adapt the blasting plan without compromising safety.","Cross-functional coordination — collaborate with engineers, site supervisors, and equipment operators to integrate blasting schedules into overall project timelines on construction sites.","Incident documentation and analysis — prepare detailed post-blast reports, analyze outcomes against planned parameters, and recommend process adjustments for future operations."]},"advanced":{"label":"Advanced","statements":["Organizational blasting standards — establish and continuously improve site-wide safety protocols, procedures, and training curricula for all explosives workers across multiple projects.","Regulatory strategy and advocacy — interpret evolving federal and local explosives law, represent the organization in compliance audits, and guide policy updates for gun and explosives record systems.","Workforce competency development — mentor and evaluate blasters at all skill levels, designing structured on-the-job learning pathways aligned with Job Zone 2 credential requirements.","Complex demolition planning — lead full-scope blast design for high-risk or high-visibility projects, integrating engineering analysis, community impact assessment, and multi-agency coordination.","Technology integration leadership — direct the adoption of analytical software, CAD platforms, and GIS tools across the blasting operation to improve precision and efficiency.","Risk governance and decision authority — make final judgment calls on halting or modifying blast operations when safety, environmental, or regulatory conditions are unacceptable.","Personnel resource management — allocate blasting crews, manage scheduling, and oversee performance of explosives handling teams across concurrent construction or extraction sites.","Stakeholder and client communication — present blasting plans, risk assessments, and regulatory compliance status to project owners, government agencies, and community groups using professional presentation tools.","Incident investigation and corrective action — lead post-incident investigations of blasting accidents or near-misses, identify root causes, and implement organization-wide corrective measures.","Strategic planning for explosives operations — contribute to business-level decisions on equipment investment, subcontractor selection, and operational capacity to support long-term organizational growth in the blasting sector."]}}},"sources":{"onet":"v30.2 (CC BY 4.0)","crosswalk":"https://skillscrosswalk.com","generator":"LER.me"},"attribution":"©
