What 29 CFR 1910.263 requires (plain English)
29 CFR 1910.263 is a special-industry standard whose requirements apply to the design, installation, operation, and maintenance of machinery and equipment used within a bakery. It addresses the specific machines of commercial baking: flour handling and sifting, mixers, dough brakes and sheeters, dividers, rounders and moulders, proof boxes, ovens, and slicers and wrappers.
For each type of equipment, the standard sets guarding and safeguard requirements aimed at the hazards it presents: guarding of mixer bowls and agitators (often with interlocks so the machine stops when the bowl is opened), guards on the nip points and rolls of dough brakes and sheeters, protection on dividers and moulders, and safe design and controls on ovens and proof boxes to prevent burns and gas hazards. Many provisions derive from the consensus bakery-equipment safety standards.
Like other special-industry standards, 1910.263 supplements the general-industry rules: general machine guarding (1910.212), lockout/tagout (1910.147), and others still apply in a bakery. Because commercial bakeries are a persistent source of amputation injuries, the equipment-specific guarding requirements here are the front line against hands and arms being caught in mixers, brakes, and dividers.
