What is the minimum length of a ladder required to access a roof surface 12 feet off the ground?
You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.

What is the minimum height of a ladder required for me to reach the top of the roof?

What is the minimum height required for a parachute to open safely?
The minimum height required for a parachute to open safely is typically around 2,000 feet above the ground. This allows enough time for the parachute to fully deploy and slow down the descent before reaching the ground.
What food should be cooked at a minimum 165?
Beef must be cooked until the minimum internal temperature is 155 degrees Fahrenheit. Most bacteria is on the surface of the meat, so ground meat has the surface mixed into under the surface.

How do you get coal out of the ground?
Coal is extracted from the ground through mining methods such as surface mining and underground mining. Surface mining involves removing the top layers of soil and rock to access the coal seams, while underground mining involves tunnels and shafts to access coal deposits deep below the surface. Once extracted, the coal is processed and transported for various industrial uses.
What methods are used to get coal out of the ground?
Coal can be extracted from the ground through surface mining or underground mining. Surface mining, which includes strip mining and mountaintop removal, involves removing layers of soil and rock to access the coal. Underground mining involves creating tunnels to access coal seams deep within the earth.
