Mr. Daniel A. Nastro

New York, New York 10043
Dear Mr. Nastro:
This is in response to your letter of July 1, 1986, concerning exit signs.
The Occupational Safety and Health Administration (OSHA) standard at 29 CFR [1910.37(b)(7)] requires exit signs to be [not less than six inches (15.2 cm) high, with the principal strokes of the letters in the word "Exit" not less than three-fourths of an inch (1.9 cm) wide]. This standard was adopted from NFPA 101-1970, the Life Safety Code.
As you are aware, NFPA 101 was modified by the NFPA in 1973 to include an exception to the size of the lettering. The exception states: "Existing externally illuminated exit signs, having the word "exit" in plainly visible letters not less than 4 1/2 inches high in existing buildings, other than in places of assembly, may be continued in use."
If your facilities are not places of assembly, per NFPA 101-1973, section 4-112 then externally illuminated exit signs would be in compliance with the 1973 and current NFPA Life Safety Code. Such a violation of the OSHA standard is a de minimis violation and is not subject to penalty nor does it require correction. The complete definition of a de minimis violation is enclosed.
If we may be of further assistance, please contact us.
John B. Miles, Jr., Director
