Describe the object and the history of the changes
Specify where the affected area is located, when it was noticed and how its appearance changed. Photographs taken before cleaning and information about storage, leaks and movement of the item are relevant. A description such as «mould after delivery» should be separated into an observed feature and a presumed cause of its appearance.
Agree the sampling and transfer arrangements
Cleaning the object yourself, treating it with household chemicals or mixing material from different areas may alter the original situation. Sampling, packaging and storage procedures should be agreed with a specialist or laboratory for the specific task. Photographs and a physical sample provide different scopes for examination.
Keep identification of the object separate from assessment of the consequences
Establishing the nature of a deposit is not the same as determining when it formed, the source of moisture or its effect on health. The latter questions may require additional materials and specialists. The examination should show the data supporting each individual finding.
What to prepare
- An overall view of the product and photographs of individual areas.
- Dates of purchase, delivery and discovery of the change.
- A description of storage, cleaning, moisture exposure and treatments carried out.
- Documentation for the material and information about the premises.
- A list of questions for the biologist and specialists in related fields.
What to bear in mind
Do not open potentially hazardous objects yourself or transport unknown biological materials without prior agreement. A photograph cannot reliably resolve every identification task and establish medical consequences.
Outcome of preliminary preparation
A preliminary discussion helps select the object to be examined, determine whether laboratory work is needed and avoid a situation in which the opinion addresses only some of the questions in the dispute.
