For example, a 28-foot Extension Ladder, fully retracted to its 14-foot length, cannot be used to work on a wall below a certain height because the user would be too far out from the wall. DON'Tuse step ladders in place of extension ladder or stand above highest "safe standing level" prescribed by the ladder's manufacturer. However, this three feet of ladder sometimes poses a problem because people getting onto or off of the ladder at the top have to work their way around the ladder itself.
clt art. 74 § 2o ft =:
- clt art. 74 § 2o ft = m
- clt art. 74 § 2o ft = 20
- clt art. 74 § 2o ft = 14
(1) When portable ladders are used for access to an upper landing surface, the ladder side rails shall extend at least 3 feet (. Compact and light enough to fit safely through tight spaces, yet strong and tall enough for the job, this full-size Werner Aluminum 3-Section Compact Extension Ladder reaches 23 ft. Innovative three-section ladders reduce shorter than standard two-section extension ladders making them easy to transport inside and on top of vehicles.
This three-foot rule gives a person descending the ladder from the higher level something to grab on to as they climb on without having to lean over at the edge of the roof. Or, when such an extension is not possible because of the ladder's length, then the ladder shall be secured at its top to a rigid support. Because an extension ladder needs to overlap, its maximum length when extended is less than the length you thought you bought! The following table should help you see what I mean.
