What do product safety investigators do when they go to people's homes?

I guess the process is probably similar in other countries but included my country anyway since I don't know enough about this stuff. Feel free to respond even if you're in another country!

I received injuries from using a product that is available internationally, but not sure how many or where they have actually sold. Later this week an investigator is going to come to my home to take pictures of the product. I feel like they must be doing something else too? Maybe an interview? It seems weird to come all the way out here for some photographs. If it matters, the manufacturer itself is located in a different country.

Thanks for any information provided!
