Drop Safe Device (DSD) is a device comprised of a retractable recoil mechanism which attached to the wrist band and another one end attachable to hold any type of tools (cleaning or hardware tools) or racquet. The attached badge reel enables the cleaner or player to retrieve his or her cleaning tool, working hardware or racquet easily, when the retractable cord pulls back the tools or racquet when they accidentally dropped it. Drop Safe Device benefits those who are working on a high rise building and construction. It can help prevent accidents from occurring. Imaging, if a construction work working at higher level say, at level 5 using a spanner to fix a screw and accidentally slip the spanner off his hand and drop below. If someone is working at the lower level, for sure he will be hit by the spanner. And at the badminton court, a racquet flew off from the badminton player’s hand, as a result from swinging too hard his or her racquet and with sweaty hands. The racquet may fly and hit someone.
