Protect yourself by wearing the PPE when handling the sample
Wrap sample in an absorbent material
Slide the sample inside a leak-proof waterproof tube without contaminating the tube (an assistant – protected as well– can, for example hold the tube while you slide the sample vial inside the tube)
Check that the non-contaminated assistant closes and disinfects the tube thoroughly
Remove the PPE. Perform the safety procedures (waste treatment, hand washing etc. according to the safety procedures)
