access ladders to roof top of buildings

access ladders to roof top of buildings

(OP)
Folks!

1503-44 thx

for more precision any std that stipulate that any building shall be equiped with ledder and cages?

thx

RE: access ladders to roof top of buildings

If occupied, I'd likely opt for stairs and not a ladder. It is my understanding that if ladders are provided for access, they have to be compliant. I don't recall seeing a requirement for the need for ladders.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

RE: access ladders to roof top of buildings

I could only find that access had to be provided, but the method is not described:

RE: access ladders to roof top of buildings

I would agree that I haven't seen a requirement for a ladder. I've often had to climb fairly sketchy A-Frame folding ladders to hoist myself up through a hatch that seems to be getting tighter every time I have to go through one.

RE: access ladders to roof top of buildings

I didn't realise that hoops were no longer useful (still OK in Canada) and that positive fall prevention is required... for the last 4 years.

@dik
what is the reference of the 3.6.4.4?

thx

RE: access ladders to roof top of buildings

Sorry, the 2010 (current code) National Building Code of Canada.

RE: access ladders to roof top of buildings

The need for a ladder is not a code matter, rather it is based on the service requirement. Usually, it is provided to industrial structures with the need for maintenance access, but the access is usually limited to certain personnel, or by permit.

While the OP has provided scant information on his roof top of building application, there are many governing building codes as well as the OSHA requirements:

I have a roof for shielding purposes only, will I be fined or rejected for the permit if no ladder is provided? I am not in Canada for sure.

le99 (Civil/Environmental),

There are many details that are unknown. Per Rumsfeld quote "As we know, there are known knowns. There are things we know we know. We also know there are known unknowns. That is to say, we know there are some things we do not know. But there are also unknown unknowns — the ones we don't know we don't know,"

For structures built before the passing of building codes, the structures are generally grandfathered from the requirements of new building codes.

New buildings go through a building permit process. If the AHJ approves the project without a ladder, then you don't have to have a ladder. If the approved project required a ladder, then you may be fined if the ladder was not constructed with the structure.

RE: access ladders to roof top of buildings

@bimr,

The OP clearly asked for code reference, if it exists then bring it up. You are sidestepping the issue and muddying the water.

This will make it the 3rd time that I have posted the code reference.

Link to Building Code Requirements

"Roof access is required by the 2018 IBC building code for buildings of four or more stories. Occupied roofs require access by a stairway. Unoccupied roof access can be by an alternating tread device, a ships ladder or a permanent ladder."

That would apply of course to the municipalities that have adopted the IBC.

"OSHA also recognizes the danger of caged ladders. The 2017 Update to Walking-working Surface standards introduced the requirement for ladder safety systems to be used with all ladders that extend more than 24 feet above a lower level. Cages are no longer allowed as a ladder safety system."

If you don't bother to read the link, one would assume that you are wallowing in the mud.

As always, it is also important to clarify this issue with the local AHJ.


RE: access ladders to roof top of buildings

@bimr,

Thanks for the response. I think this satisfies OP's request.

RE: access ladders to roof top of buildings

For caged ladder you can refer ANSI A14.3. Where you will have all the required information about ladders and its cage.

OSHA no longer requires cages because of the danger of caged ladders as per the 2017 Update to Walking-working Surface standards.
