Portableladders used as temporary access shall extend at least 3 feet above the upper landing surface. All portable ladders shall be of sufficient length and shall be placed so that workers will not stretch or assume a hazardous position. Follow the 4 to 1 ratio ladder rule: set the base 1 foot out from the wall for every 4 feet it reaches up.
Whenchoosing an extension ladder, use the 4 to 1 rule-1 foot away from the wall for every 4 feet of ladder height. Example: If the roof is 16 feet high, the footing/base will be 4 feet away from the wall. If the ladder is too steep, it can fall backwards on you; if it is not steep enough, it can “kick out” and collapse.
14 ratio means the height of a scaffold should not exceed 4 times of a base width.
First determine your investment goals: Consider factors such as the amount of liquidity you need, risk tolerance, and desired return. Choose your CD terms: Decide on the terms you want for each ladder rung, such as 1-year, 2-year, 3-year, and 5-year CDs. Determine the amount to invest: Calculate the total amount you want to invest in your CD
