Answer: Your vinegar should be fine, provided youâve been storing it properly. From a safety standpoint, commercially produced vinegar has a virtually indefinite shelf life, says the Vinegar Institute, an association that represents most of the worldâs largest vinegar manufacturers.nd itâs not unusual for vinegar to develop a haze or sediment, or to change color, after it has been stored for some time, says the Institute. Those changes in appearance do not make the vinegar unsafe to use, it adds.
The following analysis demonstrates results of a typical wood-framed stair stringer configuration as well as several similar configurations. Consider 15 risers at 7Â¼-inch tall with 10Â½-inch wide treads and stringers cut from SPF No. 1/No. 2 2x12s. This configuration results in an effective throat depth of approximately 5 inches for a horizontal span of 12 feet and 3 inches.
Tread depth will determine the overall length of the stairs from the riser of the bottom step to topmost riser. Code says that minimum depth of tread, where you step, is no less than 10. For service steps that may work, I try for a depth between 10 1/2 and 11 is more comfortable for many people.
