Medical personnel normally carry sharps cases. In their absence, signposting, removing or covering up sharps in such a way that they do not become a hidden hazard should be considered.
Consider that the casualty could be carrying personal medical equipment required to manage their health condition. Medical alert tags, bracelets or cards may provide an indication of this. Be alert to the potential presence of non-prescription sharps.
