Current through 2024-29, July 17, 2024
Safety barrier construction of snowmobile race tracks of any
				  type shall conform to one of the following options and shall be constructed in
				  a manner described herein and Figures 1, 2, 3, 4, 5 and 6 as appropriate.
				  Figures 1, 2, 3, 4, 5 and 6 and the specifications contained therein are
				  incorporated herein and made a part hereof.
OPTION 1 - WOVEN WIRE or SNOW FENCE
A.
1.
				General
When this option is utilized, spectators shall be protected
				  by using parallel fence construction to consist of two separate fences; one
				  fence to be located against the edge of the track, to be called the trackside
				  fence and another located at least 6 feet or more from the trackside fence, in
				  a direction away from the race track, to be called the spectator protection
				  fence. The area between the fences shall be kept clear. Either woven wire or
				  snow fence shall be used, but each separate fence shall be constructed with
				  only one type of fencing. The woven wire or snow fence shall be attached to
				  either metal or wood posts as specified herein. Post lengths shall be as shown
				  in Figure 3.
2. Materials
All materials used in the construction of the fences
				  specified shall conform to the following specifications:
a. Snow fence. Pickets shall be cedar,
				seasoned before the fence is woven, shall be straight grained and free from
				large knots. They shall be 4'0" high, 1-1/2" wide and 3/8" thick. The
				connecting wires shall be 5 double strands of 12-1/2 American gauge galvanized
				wire evenly spaced. The spacing between pickets shall not exceed 2
				inches.
b. Woven wire fence. Woven
				wire shall be standard galvanized farmfield fence, design number 1047-12-11.
				The wire shall be 47 inches high, having 10 horizontal wires of which the top
				and bottom wires shall be of 9 gauge and the intermediate wires of 11 gauge;
				and vertical stay wires of 11 gauge spaced at 12 inches.
c. Metal posts. End, intermediate, and corner
				posts shall be 2-1/2" X 2-1/2" X 1/14" angle or 2" nominal diameter galvanized
				steel pipe, minimum weight of 3.65 lbs. per foot. Braces shall be 1-3/4" X
				1-3/4" X 1/14" angle or 1-1/14" nominal diameter galvanized steel pipe, minimum
				weight of 2.27 lbs per foot. Line posts shall be standard studded "T" posts
				with a minimum weight of 1.33 lbs. per foot or standard lug "U" posts with
				minimum weight of 1.12 lbs. per foot. Posts lengths shall be as shown in Figure
				3.
d. Wood posts. Wood posts shall
				be cedar, white oak or tamarack. They shall be seasoned stock, straight and
				sound, and shall have been cut from live growing trees. They shall have all
				knots trimmed flush with the surface. Post diameters shall conform to the
				following: End, intermediate and corner posts shall have a minimum diameter of
				4 1/2" at the small end. Braces shall have a minimum diameter of 3" at the
				small end. Line posts shall have a minimum diameter of 3".
3. Installation
a. General. The fence shall be installed as
				shown in Figure 3, in conformity with these specifications, except that only
				the front (trackside) fence shall be required to have end, corner, or
				intermediate posts set in Portland cement concrete. At the time of racing the
				top of the fence shall be at least 3'6" above the track surface.
b. Posts. Holes for wood posts shall be dug
				to full depth as appears in Figure 3. Metal posts shall be set by means of a
				hand or mechanically operated post driver. An intermediate post shall be
				installed at least every 100 feet. Posts shall be set on 10 foot
				centers.
c. Bracing. Bracing shall
				be installed at all end, corner and intermediate posts as shown in Figure
				3.
d. Erection of snow or woven
				wire fabric. Fencing shall be stretched taut. For snow fence all strands of
				wire shall be attached to each post. For woven wire fence the top and bottom
				strands of wire shall be attached to each post and the alternate interior
				strands of wire shall be attached to alternate posts. Splicing of the wire
				shall be permitted at posts only and each horizontal strand of wire shall be
				wrapped completely around the post. The wire strand shall be securely fastened
				by winding the end of the wire about the same strand where it leads up to the
				post. This type of fastening shall be used at each end and the corner post.
				Staples for wood posts shall be fully driven into corner, end or bracing posts
				but at line posts they shall be driven so as not to restrict the horizontal
				movement of the wire.
e. Baled hay.
				The trackside fence shall be buffered by at least two parallel layers of baled
				hay at least 3'0" high as shown in Figure 4. The baled hay shall be laid
				lengthwise along and directly against the fence. The baled hay shall be tightly
				baled and shall be replaced when damaged or when its condition is such that in
				the judgment of the Commissioner it will not accomplish the purpose of
				buffering the trackside fence.
f.
				Rub-rails. As an alternative to buffering by baled hay, rub-rails may be
				installed on the trackside fence as specified in Figure 6. Rub-rails and splice
				plates shall be of dry and well seasoned Number 2 common grade stock of
				northern white pine, Norway pine, or Number 1 construction grade of eastern
				spruce, eastern hemlock, or tamarack, and shall be dressed on all sides. The
				dressed dimensions shall be 1 5/8" X 9 1/2" and of a length indicated in Figure
				6.
