rob mine is the same and I asked when I took it out if it could be increased to a higher height and they said they wouldn't insure me any higher than that. It also doesn't include the property being worked on which is a bit of nonsense.
I had a guy today that got on my goat a bit, he came up and said...
"what is the wedge for?"
I said, "Its to level the ladder to reduce movement".
"Wouldn't you be better putting it the other way, to stop it slipping out",
I said "No, because its slopped the foot could slip of then, and its not to stop the ladder slipping, its to level it".
"I am just saying, I know what I am talking about, I worked with ladders all my life, but you young ones just want to take short-cuts"
I said "Its nothing to do with taking short cuts or young ones, a window cleaner that has used ladders all his life too, taught me that's way to do it".
He said "Do you mind if I ask you, how do you get away with that".
By this time he was annoying he.
"Get away with what", I said.
He replied "Using ladders".
"Why do you think I shouldn't".
"Health and safety"
I said "Health and safety doesn't say you cant use ladders".
he said "No, you cant use ladders for height access unless its on a scaffolding".
I replied "Well I am licence and insured to use a ladder, and my insurers say differently".
he said "I am just saying I know what I am talking about, I have seen people fall of big triple tier ladders".
I replied "This is a triple tier set".
He said "No, I mean real ladders, ones that would go above the building".
I laughed, now as well as telling a window cleaner what the laws are on using a ladder that contradicts anything I have read, heard or seen before, he was giving me his own definition of what a real ladder was, I had had enough and carried on my way. its true there is an 1di0t born every minute.
Window cleaners have used ladders for over 100 years, that wont change any time soon.
More to the post though, hydros post there is good advice with handling the customer.
