These body bags are designed to help rescue officers mark the victims as men or women, and further divided into the old, the youth and children — what we have then is a total permutation of 6 identifying categories. In this way, the work becomes more systematic and families can quickly find their loved ones. Rescue officers can withdraw a slot-in label to check the corresponding search categories. Personal objects of the victims, such as ID cards and jewelry, can also be indicated on the label. Families first match the category, before confirming the identities by the personal objects, and finally, they can open the body bags for a physical verification.
