What about security bars over sliding glass doors? This one had
a key lock on the inside…in case of a fire the resident would need
a key…I need help on the proper fire safety installation if a residence
has security bars…
David, I think what Steve is getting at is;
that bars, grills covers, screens or similar devices are permitted to be placed over emergency escape and rescue openings, bulkhead enclosures, or window wells that serve such openings, provided the minimum net clear opening size complies with the 5.7 s.f. rule in R 310.1.1 and such devices shall be releasable or removable from the inside without the use of a key, tool or force greater than that which is required for normal operation of the escape and rescue opening.
In short, if it is not a means of rescue opening or the sole means of egress out of the dwelling, than it would be OK.
