MSHA Part 56 Workplace Examination Daily Checklist
By Johnson on May 30, 2026
MSHA Part 56 workplace examination is a daily federal requirement for every surface metal and nonmetal mine — and in a cement quarry, where blasting, heavy mobile equipment, highwalls, and conveyor systems operate in close proximity, a missed examination is not a paperwork oversight but a direct path to a fatality or a significant MSHA citation. Part 56.18002 requires that a competent person examine each working place at least once per shift, before work commences, and that examination records be kept for one year and made available to MSHA inspectors on demand. The examination must identify hazardous conditions, record them, and document corrective action — not simply confirm that a walk-around occurred. Cement quarry operations present a specific and challenging examination scope: active blast zones, ground control hazards on bench faces, mobile equipment traffic corridors, crusher feed points, and process dust accumulation zones all require structured, CMMS-backed assessment every single shift.

Your Part 56 workplace examination record is the first thing an MSHA inspector requests during an unannounced inspection. A paper logbook that is incomplete, unsigned, or missing shifts creates immediate citation exposure. Oxmaint captures every examination with timestamp, examiner ID, hazard photos, and corrective action — the complete Part 56 record in one searchable system.
Highwall, Bench Face, and Ground Control Examination
Highwall failure is the leading cause of fatalities in surface quarry operations. MSHA Part 56.3200 requires that quarry walls, banks, and slopes be examined for hazardous conditions. Post-blast examination is mandatory before personnel re-enter the blast zone. Ground control failure in a cement quarry — where blast frequency is high and bench heights often exceed 15 metres — can kill equipment operators and examiners who have not systematically assessed the face condition before commencing the shift.
Ground Control Hazard Classification — Cement Quarry Bench Face
Acceptable
Bench face stable, no loose material, no visible cracking. Normal operations may proceed.
Document and proceed
Caution
Minor loose material visible. Small tension cracks at crest. Scaling required before work.
Scale before personnel enter
Restricted
Active cracking, overhang, or large loose blocks identified. Equipment exclusion zone required.
Exclusion zone — supervisor notified
Shutdown
Imminent failure indicators — tension cracks with displacement, seepage, or significant overbreak.
Immediate area shutdown — MSHA notification may apply

Area 02 — Mobile Equipment Traffic Zones
Haul Road, Traffic Zone, and Berm Examination
MSHA Part 56.9300 requires that berms or bank barriers be provided on the elevated sides of roadways where equipment could otherwise go over the edge. Berm condition, haul road surface integrity, and traffic intersection visibility are the three most inspection-cited road hazards in quarry operations. A haul road without adequate berms or with a surface rut deep enough to destabilise a loaded haul truck is a citation and a fatality risk in the same moment.
Berms and Edge Barriers
Berm height — minimum wheel height of largest vehicle using road
No gaps at berm that could allow equipment to pass through
Berm continuity on all elevated road edges — no missing sections
MSHA 56.9300 — required on elevated road edges
Haul Road Surface
No ruts deeper than 300mm on active haul roads
No large loose rock on haul road surface — tire hazard
No water ponding — standing water obscures depth hazards
Road width adequate for two-lane traffic if applicable
Intersections and Visibility
Blind intersection sight lines — no obstructions within 30m
Traffic control signs in place — Stop, Yield, Speed
Dust suppression adequate for visibility on active roads
Night lighting operational at all intersection points

Area 03 — Process Dust and Hazardous Materials
Dust, Air Quality, and Hazardous Material Zone Examination
Cement quarry operations generate significant silica-bearing rock dust at crusher feed points, haul road surfaces, and blast zones. MSHA Part 56.5001 and the silica dust standard require that dust exposure be controlled and monitored. A workplace examination that does not specifically assess dust accumulation at crusher feed platforms, conveyor transfer points, and blast zones fails to address one of the highest-occupational-health risks in the cement supply chain.

A workplace examination that is not recorded is legally the same as a workplace examination that was not done. Oxmaint builds your Part 56 record automatically — examiner sign-off, hazard classifications, corrective action timestamps, and photo attachments — all stored and searchable for the one-year retention period MSHA requires.

FAQs
Frequently Asked Questions — MSHA Part 56 Workplace Examination
What does MSHA Part 56.18002 require for workplace examinations at cement quarries?
Part 56.18002 requires that a competent person examine each working place at least once per shift, before work begins, and record conditions found. If hazardous conditions are found, they must be corrected before miners are exposed — or the area must be posted until corrected. Records must be kept for one year and made available to MSHA on request. Track Part 56 records in Oxmaint.
What makes a workplace examination record acceptable to MSHA during an inspection?
An acceptable Part 56.18002 record includes the date and time of examination, the working areas examined, any hazardous conditions found, corrective actions taken, and the name of the competent person who conducted the examination. Records with missing signatures, incomplete area coverage, or no hazard findings over many consecutive shifts are scrutinised by inspectors as evidence of a cursory examination. See how Oxmaint structures compliant records — book a demo.
How should a cement quarry handle a highwall hazard found during the pre-shift examination?
The hazardous area must be posted with a warning and barricaded to prevent personnel entry. The examiner must notify the supervisor immediately and record the hazard with a description and location. Work may not resume in that area until either the hazard is corrected (scaled, blasted, or stabilised) and re-examined, or a supervisor has assessed and authorised a modified operating approach with defined exclusion zones.
Can a supervisor complete the MSHA Part 56 workplace examination, or must it be a dedicated examiner?
MSHA requires the examination to be performed by a "competent person" — defined as someone with knowledge, training, and experience to identify hazards. A shift supervisor who meets this competency requirement can conduct the examination. The key requirement is that the examination is substantive, covers all working areas, and is documented with the competent person's name. The role title is secondary to the competency determination.
What MSHA citation penalty applies if workplace examination records are incomplete or missing?
Missing or incomplete Part 56.18002 records can result in citations with penalties from $161 to $15,625 per violation, depending on severity classification. If MSHA finds that a hazardous condition existed and no examination record covers that shift, the penalty assessment increases substantially. Repeat violations from the same mine within a 15-month period trigger higher proposed assessments under MSHA's regular assessment rules. Build your compliant record system in Oxmaint — Sign Up Free.
