Abstract
A system and related methods for preventing back injury involving backpacks, wherein a weighing feature is provided for weighing the payload of the backpack and determining whether the payload is above a predetermined weight limit, and an alarm (e.g. audio, visual and/or tactile) is provided for alerting a user and/or a guardian that the weight of the payload is too great and must be reduced prior to safely carrying the backpack.
