s i EXTENSION LADDERS r ' Extension ladders are lightweight, durable, adjustable in length,made up of two or more sections that travel in guides or brackets,are a least 12 inches wide,and are not longer than 24 feet per section. When using extension ladders: Handle the ladder with caution. A large ladder is heavy and tricky to handle. Don't hesitate to get help from a co-worker. • Place the ladder on a substantial base with clear access at the top and bottom. • Use a ladder with safetyfeet if there is any danger of skidding or slipping. • Place the ladder's feet on a substantial and level base,not on movable objects. • Never lean a ladder against unsafe backing,such as loose boxes or barrels. Use the four-to-one ratio: that is, place the ladder so its feet are one foot away from what it leans against for every four feet in height to the point where the ladder rests. Example: If the top of a 16 foot ladder leans against a wall,its feet should be placed four feet from the wall. Never place a ladder in front of a door or passageway unless the door is locked,blocked or guarded by someone. Never use any ladder in a horizontal position such as a runway or scaffold. i Extension ladders should be tied,blocked or otherwise secured to prevent movement. All extension ladders should extend a minimum of 36 inches above the landing. When ascending or descending a ladder: 1 • always face the ladder, • hold on with both hands, • never slide down a Iadder, • do not climb higher than the third rung from the top,and • be sure that your shoes ire not greasy,muddy or slippery before your climb. Since metal ladders are electrical conductors,they should never be used around electrical circuits or in places where they may come in contact with such circuits. Metal ladders should be marked with signs or decals reading"Caution-do not use near electrical equipment". Other safety precautions: i 1. Never use makeshift ladders such as cleats fastened across a single rail. 2. Before using a ladder, inspect it for defects. 3. Never use a defective ladder. Tag it or mark it so that it will be repaired or destroyed_ 4. Keep ladders clean and free from flirt and grease,which might conceal defects. j 5. Don't use ladders during strong wind except in an emergency, and then only when they are securely tied. 6. Do not leave placed ladders unattended,especially outdoors,unless they are anchored at top and bottom. 7. It is dangerous to reach out too far from a ladder in any direction;move the ladder as the work requires. z i i
