Today, hydraulic power is used to operate many different tools and mechanisms. In a garage, a mechanic raises the end of an automobile with a hydraulic jack. Dentists and barbers use hydraulic power to lift and position their chairs. Hydraulic doorstops keep heavy doors from slamming. Hydraulic brakes have been standard equipment on automobiles since the 1930s. Most automobiles are equipped with automatic transmissions... 

All mechanical doors are required by law to be capable of hand operation in the event of power failure, and doors of all types must have fastenings which can be opened from either side in case an operator is shut in the store. Targer rooms must have an escape door or breakout hatch or panel at the end remote from the doors, for use in an emergency. Door openings are frequently fitted, additionally, with plastic strip curtains or doors, to reduce infiltration when the main door is open. 

Do not operate gasoline-powered engines in confined areas such as garages or basements. Do not leave a car, mower, or other vehicle running in an attached garage, even with the door open. 

Lift trucks are available to meet a variety of clearance restrictions. Noteworthy is narrow-aisle equipment. Another accessory worthy of consideration is the multilift mast, which permits lifting loads over 3.7 m (12 ft). Of special importance in specifying any mast is that it will clear the various door openings it must enter, which includes those of trucks, railcars, and buildings. To meet most conditions, the collapsed height of the mast must be 2235 mm (88 in). An ideal lift truck for chemical-plant distribution warehouses would have 2000-kg (4000-lb) capacity electric (battery) propulsion solid-state controls power steering Trilift mast, up to 4.9 m (16 ft) [2235 mm (88 in) collapsed] side shifter operator guard solid tires (except for outside use) and adjustable forks.
