The average height for males in the U..S. is about 5' 9" and 5' 4" so the mean height for both males and females should be about 5' 5". The eye level is about 6 " below the top of the head. Therefore, 5 feet should be an acceptable definition for eye level of the average person.
An internet search may reveal a different height. However, I believe 5 feet is pretty close.

Subject: [DCHAS-L] Chemical Shelving Heights
Does anyone know the OSHA height requirement for storing chemicals, and the definition of "eye level"? One school of thought says no higher than five feet for any chemical, with the interpretation that shelves would have to be lower than five feet, as bottled chemicals may themselves be, e.g., a foot high. Another stated requirement is no higher than eye level for caustic chemicals. Thank you!
