Technical circumstances of an occupational accident

When it is needed

When participants explain the event mechanism differently, materials contain contradictions or the technical part of the commission's findings needs checking.

What we examine

Workplace, equipment and items involved in the event.
Photographs, video recordings, diagrams and inspection records.
Documents describing the brief, working procedure and intended protective measures.

Materials to prepare

Investigation materials, including appendices to the report and records.
Original photographs and video with their source and time of acquisition.
Equipment technical passport, manual and maintenance documents.
Instructions, work permits, process sheets and information about scene changes.

Sample questions

Which sequence of technical events can the materials provided establish?
Which hazardous factors were present in the work area considered?
Which protective devices and organisational measures were intended for this operation?
Is the incident mechanism described in the documents consistent with the recorded scene?
Which missing information limits checking of the explanation proposed?

How the work is carried out

We will define the operation, period and explanations to be checked.
We will compare primary recordings, technical documentation and results of the inspection available.
We will substantiate established circumstances and separate them from assumptions.

Result

A specialist's report describing source data, explanations checked, technical factors and limits of findings.

What affects the conclusions

The site's current condition may differ from its condition on the event date. The examination does not replace a commission's investigation or establish participants' legal culpability.

Frequently asked questions

Can we start without a site visit?

Yes. Document analysis can establish which questions can be resolved from the available materials and whether inspection is needed. The final scope is agreed after familiarisation.

What if the equipment has already been repaired?

Preserve repair information, removed parts, photographs and records. We will identify the object's alteration in the examination and take it into account when assessing possible findings.

Event chronology identifying the source of each fact

Technical analysis requires a distinction between the work brief, actions actually recorded and participants' explanations. The timeline identifies site preparation, operation start, mode changes, the appearance of a hazardous factor, stopping work and subsequent actions. Each event is marked with its supporting evidence.

A video, equipment log, authorisation document and eyewitness account have different capabilities. If source clocks differ, the magnitude and nature of the discrepancy are checked. Recordings cannot be combined without explanation merely because their timestamps look close.

Preserve original files and information about the device or system from which they were obtained.

Mark the start and end of the available period, together with any gaps.

Attach a workplace diagram showing equipment and participant locations.

State changes to the scene after the event.

List separately facts supported only by accounts.

The possible sequence is then compared with the equipment's design and intended process. Where contradictions arise, it is important to show which source supports a particular stage and which alternative explanation remains possible. A breach recorded in a document and its technical connection to the incident are different examination questions.

This package enables discussion of the event mechanism and sufficiency of source data. It does not determine the medical severity of consequences, insurance classification or participants' legal culpability.
