Guidelines

This checklist covers regulations issued by the U.S. Department of Labor, OSHA under the General Industry standard 29 CFR 1910.263. The requirements of this checklist apply to the design, installation, operation, and maintenance of machinery and equipment such as horizontal dough mixers; vertical mixers; dividers; moulders; manually fed dough brakes; hand trucks, lift trucks, racks and air conditioning units; slicers and wrappers; and biscuit and cracker equipment such as cheese, fruit, and food cutters, and reversible dough brakes and box- and roll-type dough sheeters. The regulations cited apply only to private employers and their employees, unless adopted by a state agency and applied to other groups such as public employees.

This checklist does not address proof boxes; fermentation rooms; troughs; conveyors; ingredient premixers, emulsifiers, etc.; chain tackle; trough hoists, etc.; pan washing tanks; bread coolers, rack type; doughnut machines; open fat kettles; steam kettles; meal, peanut, and fig grinders; sugar and spice pulverizers; cross-roll brakes; rotary die machines, pretzel rolling, and pretzel-stick extruding machines; pan cooling towers; chocolate melting, refining, and mixing kettles; and peanut cooling trucks. See 29 CFR 1910.263 for regulations on these types of equipment.

  8. Are all horizontal dough mixers with power and manual dumping arrangements provided with safety devices that
    1. Engage both hands of the operator when the agitator is in motion under power and while the bowl is opened more than one-fifth of its total opening? [29 CFR 1910.263(e)(1)(v)(a)]
    2. Prevent the agitator from being started while the bowl is more than one-fifth open without engaging both hands of the operator? [29 CFR 1910.263(e)(1)(v)(b)]
  9. Is every horizontal dough mixer equipped with a full enclosure over the bowl, which is closed at all times while the agitator is in motion? [29 CFR 1910.263(e)(1)(viii)]

    Note: Only minor openings in this enclosure, such as ingredient doors, flour inlets, etc., each representing less than 1-1/2 square feet in area, shall be capable of being opened while the mixer is in operation.

  10. Are all overhead covers or doors on horizontal dough or vertical mixers that are subject to accidental closure (1) counter-balanced to remain open or (2) provided with means to hold them open until positively released by the operator? [29 CFR 1910.263(e)(1)(x) and (e)(2)(i)]
  11. Do vertical mixers have positive bowl locking devices, which require an operator for unlocking? [29 CFR 1910.263(e)(2)(iii)]
  12. Do vertical mixers have devices for moving bowls weighing more than 80 pounds (with contents) into and out of the mixing position of the machine? [29 CFR 1910.263(e)(2)(iv)]

    Dividers

  13. Does the back of the divider have a complete cover to enclose all of the moving parts, or are they enclosed or guarded to remove the hazards? [29 CFR 1910.263(f)(3)]
  14. Does the rear cover have a limit switch that prevents the machine from operating when the cover is open? [29 CFR 1910.263(f)(3)]
  15. Is the guard on the back hinged so that it cannot be completely removed? [29 CFR 1910.263(f)(3)]
  16. If a catch or brace holds the cover open, is it designed so that vibrations or minor bumping will not cause the cover to release and drop on a student/teacher? [29 CFR 1910.263(f)(3)]

    Moulders

  17. Do mechanical feed moulders have hoppers that are connected to the proofer and designed so that the operators' hands cannot get into the hopper and come into contact with the in-running rolls? [29 CFR 1910.263(g)(1)]
  18. Do hand fed molders have a belt-feed device, or is the hopper extended high enough so that the hands of the operator cannot get into the feed rolls? [29 CFR 1910.263(g)(2)]
  19. Is the top edge of the hopper well rounded to prevent injury when it is struck or bumped by the operator's hand? [29 CFR 1910.263(g)(2)]
  20. Is a stopping device within easy reach of the operator who feeds the molder and another stopping device within reach of the operator taking the dough away from the molder? [29 CFR 1910.263(g)(3)]
