Bonner III -2-February 22, 1977 <br />All tows met this requirement with the exception of tow #3 which <br />had a stopping distance of 28 feet. Tow #3 is not equipped with <br />an automatic brake. <br />The tows were then operated to determine if they met the require­ <br />ments of para. 2.2.5.4.2, ANSI Standards which requires that a <br />safety gate be so located that the distance from the stopping device <br />(safety gate) to the first obstruction or point of reversal of direc <br />tion of the towing outfits is 150 per cent of the distance required <br />to stop the empty lift operating at maximum speed. All tows met <br />this requirement with the exception of tows #3 and #6. <br />Warning signs were inspected to determine whether or not they met <br />the requirements of para. 2.1.1.2.4 of the ANSI Standards. Although <br />the signage did not conform to the letter of the ANSI Regulations <br />(they were not uniform in size and wording) in my opinion they con­ <br />form with the spirit and intent of the Regulation. <br />OTHCR MATTERS: <br />Although not required in the ANSI Regulations, the operator of the <br />area has erected fencing around the tow equipment at the loading <br />and unloading areas. From the standpoint of safety, I recommend <br />and advise that these fences be provided and maintained in place in <br />a good state of repair. The fencing in place on Phase JI was ade­ <br />quate and in good repair. I noted several instances of fence dis­ <br />repair on the Phase I tows. <br />In conclusion, based upon my inspection of Phase I and Phase TI of <br />the Ski-Tonka facilities, it is my opinion that the facilities <br />inspected meet the ANSI Standards with the following specific excep <br />tions: ’ <br />a) Tows #3 and #6 require either: <br />Operation at a slower speed, or <br />installation of brakes, or <br />relocation of safety gate. <br />b) <br />operations. <br />Efforts should be made to repair fencing on Phase I <br />Yours very truly. <br />f < <br />Gerald T.
