Safety Glass required ?

Does this Casement require a safety bar or glass?

Chuck_Lambert · November 13, 2009, 11:36pm

Safety glass and/or a bar at 36 inches that can withstand 50 psi.

belliott · November 14, 2009, 12:19am

Yeah the floor has pretty lights outside:)

Why do you say no?

lkage · November 14, 2009, 12:31am

If the bottom pane of glass is 9 sq. ft. or less, then no.

That is what I get also as this illustration shows.
Judging from what you see (what say you)?

Bob…your photo shows an improper installation. The 2006 IRC states:

R613.2Window sills. In dwelling units, where the opening of an operable window is located more than 72 inches (1829 mm) above the finished grade or surface below, the lowest part of the clear opening of the window shall be a minimum of 24 inches (610 mm) above the finished floor of the room in which the window is located. Glazing between the floor and 24 inches (610 mm) shall be fixed or have openings through which a 4-inch-diameter (102 mm) sphere cannot pass.

Exceptions:

Windows whose openings will not allow a 4-inch-diameter (102 mm) sphere to pass through the opening when the opening is in its largest opened position.

Openings that are provided with window guards that comply with ASTM F 2006 or F 2090.

This section is not applicable to fixed or stationary windows. If any part of the clear opening area of an operable window is located more than 72 inches (1829 mm) above the finished grade, this section requires that the lowest part of the clear opening be at least 24 inches (610 mm) above the floor surface of the room in which it is located. Windows may be located less than 24 inches (610 mm)above the interior floor surface only if they meet any one of the following criteria: 1) are fixed, 2) are located 72 inches (1829 mm) or less above grade, 3) have openings which will not allow passage of a 4 inch (102 mm) diameter sphere, or 4) are equipped with guards in accordance with ASTM F 2006 or F 2090. ASTM F 2090 addresses window fall prevention devices specifically associated with emergency escape and rescue openings, while ASTM F 2006 addresses devices at non-emergency escape and rescue openings.

Ahhh because it is not required. The lights in your eyes???

2nd floor needs protection as MB pointed out.

Also if it is one you inspected probably needs gfci too, someone might run an exteinson cord out the window to a blender ;)

Addresses the fall hazard instead of the cut hazard?

mcyr · November 14, 2009, 1:41am

I think we need to read this right;
R308.4 Hazardous Locations.

The following shall be considered specific hazardous locations for the purposes of glazing: (not the semi-colon)

1-7

Glazing in an individual fixed or operable panel, other than those listed above, that meets these conditions:

a. pane greater than 9 sq. ft.

b. bottom edge less than 18"

c. top edge greater than 36 "

d. one or mor walkings surfaces within 36" horizontally of the glazing.

Unless I am wrong, it needs to be safety glazed because it meets item b. and meets item d. of article 7.

:)

belliott · November 14, 2009, 2:04am

Must meet all 4 criteria.

It seems a protective bar must be placed at 36 in.

I never measured sq ft so here is another measurement that shows the lower handle at about 23 in up off the floor as a clue.

lkage · November 14, 2009, 2:11am

Correct…

http://www.nachi.org/safety-glass-for-inspectors.htm

I think that is where it is confusing Bob,
does it?
I read it like either or on all of them.
Maybe not, don’t know, I’ll have to dig it up somewhere.

mcyr · November 14, 2009, 2:19am

Yeah, your right Larry, I failed to read the meet all conditions:

I owe you one. Got to keep my glasses on for krist sake:mrgreen:

belliott · November 14, 2009, 2:20am

The whole 200 plus units are most likely this way guys.
Does that appear to be over 9 sq feet?

mcyr · November 14, 2009, 2:40am

Not unless you figure both panes Bob. You didn’t measure it?
The pane section would have to be 3’x3’ and it don’t look that big.

belliott · November 14, 2009, 2:51am

No but it looks like a close call.
That’s why I am here with it.:neutral:

bkelly2 · November 14, 2009, 2:51am

Can you call the guy holding the tape in the pictures, maybe he measured the glazing???

And as we are not Technically Code Inspectors Bob, you are well within your scope to recommend any Safety Upgrades you deem applicable. I would not have a problem with safety glass upgrade.

belliott · November 14, 2009, 2:54am

Very good as that is what I ended up doing , but it still has me a little …big word warning!..perplexed.
