Machinery Incident Reporting, Compliance & Technical Follow-Up
Capture Events Across Fabrication, Testing, and Service
Relevant incident and near-miss categories include:
- Crush injuries during component positioning or fit-up
- Dropped, swinging, or shifting loads
- Rigging failures and lifting near misses
- Contact with rotating shafts, couplings, chucks, and cutting tools
- Ejected workpieces, tools, fragments, or test components
- Unexpected movement during programming or functional testing
- Hydraulic injection injuries and pressure-release events
- Uncontrolled descent of raised machine sections
- Electrical shock, arc-flash events, and unexpected energization
- Welding burns, eye injuries, and fume exposure
- Grinding-wheel failures and flying particles
- Cuts from unfinished edges and fabricated parts
- Manual-handling and awkward-access injuries
- Falls while accessing large equipment
- Customer-site installation and service incidents
Capture the Machine Configuration Behind the Event
An equipment name alone may not explain the conditions present during a machinery incident.
Record:
- Project, work order, and machine serial number
- Production asset or machine-under-build identification
- Build, test, installation, or service stage
- Task and personnel involved
- Mechanical, electrical, hydraulic, and pneumatic configuration
- Available energy sources and isolation status
- Guarding and access conditions
- Temporary connections or test arrangements
- Relevant drawing, procedure, or control revision
- Load weight and lifting arrangement where applicable
- Pressure, speed, or other relevant test conditions
- Immediate response and temporary restrictions
- Photographs, statements, and supporting technical documents
Connect the investigation to the configuration in place at the time, particularly when subsequent work changes the equipment.
Investigate Technical and Organizational Causes
Event → Configuration Review → Task and Energy Review → Contributing Causes → Corrective Work → Verification → Closure
Investigations may need to examine:
- Whether all energy sources were identified
- Whether a temporary test arrangement introduced an uncontrolled hazard
- Whether the procedure matched the actual machine
- Whether a component was adequately supported
- Whether a change was communicated to the next team
- Whether the task required access inside a hazardous area
- Whether engineering assumptions matched installation conditions
- Whether similar equipment could present the same problem
A correction may require an engineering change, a safer work method, improved tooling, or a revised commissioning sequence.

Requirements depend on the machinery and activity involved. OSHA provides separate provisions for particular machine types; one machine-specific standard should not be applied indiscriminately to all presses or production equipment. OSHA: Machinery and Machine Guarding, Materials Handling and Storage
Treat Testing and Positioning as a Defined Safety Activity
Some work requires temporary energization to test or position equipment. Under 29 CFR 1910.147(f)(1), covered situations require a defined sequence for clearing equipment and personnel, removing energy-control devices, testing or positioning, and then deenergizing and reapplying energy controls before servicing continues.
Record the task, responsible personnel, access arrangements, and return to the controlled servicing condition. A “test mode” label alone does not resolve hazardous-energy obligations. OSHA: Control of Hazardous Energy
Evaluate Electrical Troubleshooting Separately
Electrical troubleshooting can present hazards beyond unexpected machine movement. OSHA’s electrical work-practice requirements address deenergization and the conditions under which work on energized parts may be performed.
Connect the electrical work assessment with the machine’s energy-control arrangements and the qualifications of personnel performing the task. OSHA: Electrical Safe Work Practices
Distinguish Workplace Compliance From Machinery Design Requirements
Machinery manufacturers manage both employee safety and the safety requirements associated with the equipment they supply.
| Requirement category |
Primary purpose |
Relationship to EHS records |
| OSHA workplace requirements |
Protect employees performing manufacturing, testing, servicing, and installation work. |
Document workplace hazards, work practices, incidents, inspections, and corrective actions. |
| Machinery design and risk-assessment standards |
Guide identification and reduction of hazards associated with machine design and intended use. |
Link relevant design findings to workplace events and engineering follow-up. |
| Customer specifications and acceptance requirements |
Establish contractual expectations for the delivered equipment. |
Reference applicable acceptance findings and responsible technical owners. |
| Destination-market product requirements |
Establish requirements for placing machinery on a particular market. |
Coordinate with the responsible product-compliance team and retain references to its determinations. |
| Environmental permits and waste requirements |
Govern applicable emissions, discharges, waste handling, and releases from manufacturing activities. |
Track facility-specific tasks, findings, and corrective work. |
ISO 12100, for example, addresses machinery risk assessment and risk reduction. It serves a different purpose from an OSHA workplace inspection. Applicable consensus standards, customer requirements, and destination-market obligations should be determined for the specific equipment. ISO: Safety of Machinery—Risk Assessment and Risk Reduction
For robotic systems, risk assessment must consider integration and tasks such as programming, setup, maintenance, and troubleshooting. OSHA’s technical guidance discusses these activities and relevant safeguarding considerations. OSHA: Industrial Robot Systems and Industrial Robot System Safety
Dexur’s EHS records can support this coordination while engineering and product-compliance teams retain responsibility for technical validation and conformity decisions.
