The OSHA guard safety scale can be used to check openings in barrier guards during their design, installation and inspection for compliance with Table O-10 of OSHA 29 CFR 1910.217. This unit is 33.5" long, so it includes the maximum permissible opening of 6" at distances greater than 31.5". The yellow-colored, three-section folding scale has English units (inches) on both sides. It is made of durable anodized aluminum and has easy-to-read text and graphics that will not rub or scratch off.
