5、ARDS ANSI O1.1-1 (2015) Forward (This forward is not part of American National Standard O1.1-1 (2015).) Historical Perspective The revision of the original Safety Code for Woodworking Machinery was approved in 1944. The Standards Committee was reorganized in 1952, and the scope of the standard was c

6、hanged. A comprehensive revision of the section on cooperage machinery was completed and a new section dealing with radial-type saws was included. The resulting standard was issued in 1954 and reaffirmed in 1961. In 1969 the Standards Committee was again called and revised the 1954 (R1961) standard.

7、 The 1971 revision corrected and clarified several issues related to guarding and incorporated as a section of the standard an important head note in Section 6.1 of earlier versions of this standard. The standard was again revised and issued in 1975. In 1979 an amendment was made to the 1975 edition

8、 Subsequent updates were published in 1992, 2002, 2004, 2009 and 2013. Prior to the 2004 edition, the committee adopted a resolution regarding the US Occupational Safety and Health Administration (OSHA). The resolution remains in agreement with this edition and is therefore reproduced here: Resolve

9、d: As the standards developed by this committee are relevant to the health and safety of workers in the wood working industry, and as this committee is charged with developing such standards and recognized for its expertise in wood working industry safety and machinery, it is the intent and expectat

10、ion of this committee that newly published versions of standards developed by this committee be adopted by the US Department of Labor as regulations under the United States Occupational Safety and Health Act. The 2004 edition marked the beginning of a new process for the standard. Hereafter, the O1.

11、1 standard will remain relatively static and new standards will be developed for specific machine within the scope of the O1.1 standard. Thus the O1.1 standard is considered an “umbrella” under which subsequent standards are developed. As a continuation of that process, the draft of the first editio

12、n of ANSI O1.1-1, Safety Requirements for Fixed Angle Jump Saws was completed in 2007. Upon completion of the consensus review process, ANSI O1.1-1-2007 was then first published in 2010. Suggestions for improvement of this standard are welcome. They should be sent to the Wood Machinery Manufacturers

18、an National Standard O1.1-1 Safety Requirements for Fixed Angle Jump Saws STANDARD REQUIREMENT EXPLANATORY INFORMATION (Not part of American National Standard for fixed Angle Jump Saws Safety Requirements) 1 Scope, Purpose, and Application 1.1 Scope This standard covers the safety requirements for t

19、he design, installation, care and use of single blade, non-adjustable cut angle jump saws and certain related accessory equipment, used in industrial and commercial applications, having a total connected power of 5 hp (3.7 KW) or greater, or having 3-phase wiring. E1.1 Scope These saws may also be k

20、nown as chop saws or cutoff saws. Jump saws have historically been pivot-mounted devices. However, modern jump saws may also use linear vertical travel and are therefore included in this standard. Fixed angle or non-adjustable cut angle are not intended to mean that the blade can not be adjusted for

21、 precision or capacity, but rather that its cut angle is fixed by its design. 1.1.1 Machines excluded This standard does not cover machines in which the feed and/or positioning of the work piece is automated. E1.1.1 This exclusion anticipates that the operators hands are not exposed to the cutting z

22、one when the work piece is being automatically fed into and away from the saw. 1.2 Additional requirements This machine specific standard is intended to be used in conjunction with ANSI O1.1. Where contradictions exist, this machine specific standard shall control. 1.3 Application This standard supe

23、rsedes any machine specific references to jump saws in ANSI O1.1 1.3.1 Effective Date Unless specified elsewhere, this standard shall become effective one year following the date of its publication, and apply to machines manufactured or re-manufactured after that date. 1 AMERICAN NATIONAL STANDARDS

24、ANSI O1.1-1 (2015) 2 Definitions The definition of a term in this standard is for the purpose of the standard and is not to be construed as universal in its application. E2 Definitions For additional applicable definitions, refer to ANSI O1.1 2.1 cut angle: Either (1) the angle formed by the plane o

25、f the blade relative to the work piece support or (2) the angle formed by the plane of the blade relative to the fence. E2.1 cut angle: These are typically referred to as either (1) bevel or (2) miter angle. 2.2 fence: A device, attached to the saw table, used to locate and guide a work piece relati

26、ve to the cutting tool. E2.2 fence: A jump saw fence is generally fixed in position and at 90 degrees to the plane of the blade and to the table, and positioned at the rear of the work piece relative to the operator(s). Some designs may place the blade at a different angle, such as 45 degrees, to th

27、e fence. 2.3 jump saw: A machine that utilizes a work piece support means, work piece hold down means, and a saw blade affixed to a powered arbor to cut a work piece from below in an upward motion. E2.3 jump saw: The powered arbor is mounted either (1) on an arm that pivots, or (2) on a carriage mec

28、hanism that slides vertically. In the at rest position, the saw blade is below the work piece and table surface. A jump saw typically makes a vertical cut relative to the table at a fixed angle relative to the fence. 2.4 maintenance mode: A machines operational state which is intentionally set for t

29、he purpose of performing maintenance. E2.4 maintenance mode: In this mode, personnel may be exposed to hazards not accessible during normal operation. Under these conditions, controls should be implemented to assure equivalent safety. 2.5 normal operator position: Where the operator(s) of the machin

30、e is (are) expected to be positioned when operating the machine. E2.5 normal operator position: In the normal operator position, the operator is expected to be standing or sitting with the saw table directly in front of him/her with the fence on the opposite side of the table. 2.6 operational mode:

31、A machines operational state in which it normally performs its task of cutting. This state includes a ready condition in which the machine is capable of performing a cut but has not been activated to make the cut. 2 AMERICAN NATIONAL STANDARDS ANSI O1.1-1 (2015) 2.7 table: A generally horizontal sur

32、face upon which the work piece rests when being cut. E2.7 table: Any means providing equivalent support is considered a table for the purposes of interpreting this standard. For large workpieces, the table supplied with the saw may not provide sufficient support. External support means, such as conv

33、eyors or infeed rollers are examples of equivalent support. Infeed and outfeed devices that feed, rather than support, the workpiece and finished products are not considered to be part of the table. 2.8 throat plate: A removable insert surrounding and incorporating the blade opening in the table sur

34、face. 3 References Portions of the following standards, through reference in the text of this standard, constitute provisions of this American National Standard.

37、s and Risk Assessment 5 Standards for Design 5.1 Table A work table or other equivalent support means shall be provided. E5.1 See paragraph 2.7. 5.1.1 The work table or other equivalent support means shall have sufficient size and strength to stabilize the work piece prior to clamping of the work pi

38、ece and during the cutting operation. 5.1.2 The jump saw must be adjustable to enable the work table to be fixed in position with the table surface horizontal from left to right, as seen by an operator(s) in the normal operating position. 5.1.2.1 As measured from nearest edge to farthest edge (by an

39、 operator(s) in the normal operating position) the table surface must be horizontal or sloping downward. E5.1.2.1 It is not uncommon for tables to slope downward to the rear at an angle of up to 10 degrees as a method of assisting placement of the work piece against the fence. 5.1.3 In the normal op

40、erator position, the operator(s) must be able to reach across the table of the saw so as to properly observe and position the work piece. 5.1.3.1 It should not be necessary to move from this position to place the work piece and perform the desired cut. 5.1.3.2 The operator(s) shall not be required t

41、o reach over or across the plane of the saw blade to observe and/or position the work piece. 5.2 Fence A fence shall be provided for rearward support before and during a cutting operation. 5.2.1 The fence shall provide guide means to align the work piece with the blade prior to a cutting operation.

42、4 AMERICAN NATIONAL STANDARDS ANSI O1.1-1 (2015) 5.2.2 The fence shall not move, break, or permanently deform when subjected to the forces induced in the work piece during the cutting cycle. 5.3 Blade The manufacturer shall supply with the jump saw its recommendations for blades or blade characteris

43、tics appropriate for the expected range of uses of the jump saw. This shall include the maximum and minimum recommended blade diameters. 5.3.1 The direction of blade rotation must be clearly and durably marked on the jump saw, and in a place where it is visible when changing the saw blade. 5.3.2 The

44、 speed of rotation of the spindle must appear on the model number plate or name plate of the jump saw. 5.3.3 The jump saw structure and guarding system shall prevent use of a blade larger than the specified maximum. E5.3.3 The normal method of accomplishing this is to construct the structure in the

45、area of the blade such that larger blades cant be installed. 5.3.4 Means shall be furnished to securely retain the blade under all normal operating conditions. 5.3.4.1 The blade-retaining fastener shall be tightened by being rotated in the direction opposite to normal rotation of the blade. 5.3.5 A

46、blade supporting collar shall be provided for each side of the blade. 5.3.5.1 The blade supporting flange diameter shall not be less than one-fourth the blade diameter. 5.4 Carriage or Pivot Arm The retracted position of the saw blade must be below the top surface of the table 5.4.1 If power is lost

47、 during operation, the saw blade must automatically return to the retracted position. 5 AMERICAN NATIONAL STANDARDS ANSI O1.1-1 (2015) 5.5 Work piece Hold-Down or Clamp A hold-down or clamping means must be provided to prevent movement of the work piece resulting from the forces induced in the work

48、piece during the cutting cycle. E5.5 The “Work piece Hold-Down or Clamp” can be incorporated into the “Blade Guarding System” of section 8.1, thus appearing and acting as a single device or system. 5.5.1 The work piece must be held down or clamped on both sides of the blade. 5.5.2 The height of the

49、hold down or clamp, when the work piece is released, must be adjustable to a fixed position no greater than 1/2 inch above the work piece surface. 5.5.3 Any portion of the hold down or clamp within 1/2 inch of the blade must be made of a material that will not damage the blade and will not cause sparks if contacted by the blade. E5.5.3: Aluminum, brass, or other soft, non-ferrous metals are acceptable for this
