It seems simple enough. If you have an extension ladder, extend it and lean it against the wall. What can go wrong?
- The ladder is on a rough surface. Ensure the ladder feet can accommodate that, or use a ladder pad. If the ladder cannot be made stable by either method, it should not be used here.
- The ladder is on loose gravel. Stomping it down with your feet won’t solve this problem. You will probably need to clear a space to the surface. It may be necessary to secure the ladder with ropes or stakes.
- To get sufficient height, the ladder will need to be set at an abnormally steep angle. Get a taller ladder.
- Jeff wrapped the top of the ladder rails in rags to prevent marring the wall. Take the rags off; use non-slip “bumpers” made for the purpose.
These are just some of the application issues that can arise. Rather than try to train people on every permutation they might encounter, train them on the principles. In essence, you don’t want the ladder to move once somebody is on it. You can compensate for issues with the surface by any appropriate means. So, how to set it up for various conditions can be reduced to the question of how to ensure it won’t move while in use.
Simply telling people this isn’t enough. Job training needs to include some sample practical problems with the person being trained, explaining the danger and what countermeasures could be taken. Job briefings should also cover the conditions of ladder use, the dangers posed, and solutions implemented.
