During OSHA machine safety inspections, violations typically occur involving OSHA 29 CFR 1910.215 machine-safety standards for grinders.
These violations stem from improperly adjusted work rests and tongues on bench grinders, that are sometimes referred to as offhand or pedestal grinders.
According to 29 CFR 1910.215(a)(4), shops must keep work rests adjusted closely to grinding wheels, a maximum opening of 0.125 in. to prevent workpieces from being jammed between the wheel and rest, which may cause wheel breakage. In addition, 29 CFR 1910.215(b)(9) states that the distance between the wheel periphery and the adjustable tongue must never exceed 0.250 in.
Since many shops are unaware of these OSHA-required adjustments for bench grinders, Danray Products LLC (www.danrayproducts.com) offers its bench grinder safety scale that checks the openings between grinding wheels and tongues and work rests for OSHA compliance.
The scale has a 0.250-in.-diameter hole for attaching it to bench grinders for easy and quick verification.
The orange-colored scale is made out of durable 0.090-in.- thick anodized aluminum and has easy-to-read text and graphics that will not rub or scratch off. It is about the size of a credit card for convenient carrying and storing.
