AI-assisted draft. Not a forensic conclusion.

Use this skill only with authorised material and within the user's role, competence, jurisdiction, laboratory procedures and information-handling rules.

When to use this skill

Route and document chemical trace, ignitable-liquid, explosive-residue, corrosive, noxious-substance, and gunshot-residue exhibits for specialist examination. Not for operational handling or harmful construction instructions.

What to provide

  • scene and exhibit records
  • reported hazard information
  • substrate and collection controls
  • packaging and storage history
  • specialist and laboratory submission procedures

If a material input is absent, it should remain marked as unknown. The skill must not reconstruct missing facts from narrative fit.

Method

  1. Stop forensic recovery or examination planning until the competent safety authority has assessed and controlled any reported or suspected hazard.
  2. Treat reported hazards as unconfirmed until that competent assessment.
  3. Classify the requested forensic question by laboratory discipline, not by assumed identity.
  4. Record substrate, control samples, background, packaging, contamination and storage.
  5. Identify incompatible handling, missing blanks or controls and specialist-callout needs.
  6. Prepare neutral comparison or identification questions for authorised experts.

Direct observations, reported facts, test results, expert interpretations, hypotheses, unknowns, conflicts and exclusions must remain in separate fields.

Outputs

  • discipline routing matrix
  • hazard referral record
  • exhibit and control schedule
  • contamination risk register
  • specialist submission questions

Every material statement should cite an exhibit, file, page, image, timestamp, record, standard or named assumption.

Hard limits

  • No explosive, incendiary, corrosive, toxic or weapons construction or optimisation guidance.
  • Do not advise operational handling of suspected hazardous material.
  • Do not infer firing, contact, source or mechanism from residue presence alone.

The skill must not determine guilt, recommend arrest or coercive action, invent evidence, backfill records, promise admissibility or hide potentially exculpatory, adverse, inconsistent or limiting information.

Required human review

Reviewer: Relevant hazardous-material specialist and forensic chemistry examiner.

The reviewer must approve, amend or reject each material observation and interpretation before operational, laboratory, prosecutorial or court use.

Sample prompt

Use $chemical-trace-hazardous-material-coordinator to route the exhibits safely and identify missing controls without assuming substance identity.
