There were many cases of people trapped under collapsed houses being rescued by means of a car jack and such equipment. When using a jack, however, you must be aware that it is not very stable and frequent aftershocks may cause it to fall over. So, if you are rescuing a person from under some rubble, after jacking the heavy object up, you must wedge several concrete blocks or similar objects at the fulcrum in order to avoid further accidents from occurring. Meanwhile, ropes are useful for pulling and fixing. Saws can be used as an implement for cutting through pillars, beams, or joists.
Hammers can be useful in smashing through doors and furniture.
Crowbars can be used for lifting, smashing or ripping off corrugated iron sheets.
