For example, individual wires or strands within the rope.(h) All splices shall be done according to the rope manufacturer's wire rope splice specifications.(i) A method shall be used to maintain proper rope contact with sheaves and pulleys.(j) Wire rope guides shall be lined or appropriately protected.(k) The wire rope manufacturer shall recommend the type and frequency of lubrication and corrosion protection. Ropes that have little or no motion, such as ropes in static tension systems, anchors, and guys, require special consideration for protection against corrosion. (l) Wire rope on amusement rides shall be thoroughly examined periodically, by a maintenance mechanic. Wire rope found to be damaged shall be replaced with new rope of proper design and capacity as per the manufacturer's specifications. Any of the following conditions shall be cause for replacement: 1. In running ropes, six randomly distributed broken wires in one rope lay or three broken wires in one strand in one rope lay;2. In pendants or standing ropes, evidence of more than one broken wire in one rope lay;3. Any condition which causes the loss of more than a of the original diameter of the outside individual wires;5. Kinking, crushing, bird-caging, or other damage resulting in distortion of the rope structure;7. Reduction from normal diameter of more than 3/64 inch for diameters up to and including 3/4 inch, 1/16 inch for diameters, f inch to 1 c inches, 3/32 inch for diameters 11/4 inches to l1/2 inches;8. Birdcaging or other distortion resulting in some members of the rope structure carrying more load than others; or9. Noticeable rusting or development of broken wires in the vicinity of attachments. When this condition is localized in an operational rope, it may be eliminated by making a new attachment.(m) Wire ropes used to support, suspend, bear or control forces and weights involved in the movement and utilization of tubs, cars, chairs, seats, gondolas, other carriers, the sweeps, or other supporting members of an amusement ride shall not be lengthened or repaired by splicing. In addition, these shall have a redundant support system capable of carrying the full load. Redundancy of the support system may also be accomplished with a design that includes a higher safety factor in the manufacture of the support system.

They shall be constructed in such a fashion so as to reject a four inch ball at all openings;3. They shall be designed, constructed, and erected to inhibit overturning by spectators;4. Where used, entrance, exit, and loading gates shall open away from the ride or device unless equipped with a positive latching device;5. Gates shall be designed such that if opened during the amusement ride cycle, the gate will not come into contact with the amusement ride or cause a hazard to riders; and6. Fences and gates shall be constructed as to inhibit spectator contact with the ride or rider contact with fences or gates, or both.(14)Means of Access and Egress. Safe and adequate means of access to and egress from a ride shall be provided.

The submission shall include the following: 1. Foundation drawing(s) and calculations signed and sealed by a licensed professional engineer or a letter signed and sealed by a Massachusetts registered professional engineer certifying that the existing foundation, pad, or other support structure will support the ride in all design conditions;2. A soil report for rides that require new foundation work; and3. Site specific environmental information, if this information was not already submitted to the Department. Site specific environmental information shall not be required for rides when the design covers all environmental design conditions found in the Commonwealth.(b) After the ride is erected, but prior to opening to the public, a copy of the inspection report by the designer or its representative shall be submitted to the Department.(c) If a ride, which is designed for traveling, is set up for three months or more, the following information shall be submitted to the Department for review: Documentation of the manufacturer's set-up requirements, including documentation regarding the weather or other conditions under which the ride may safely operate and the environmental design conditions. When those conditions are exceeded, the ride shall be taken down.(18)Internal Combustion Engines. (a) Internal combustion engines shall be of adequate type, design, and capacity to handle the design load.(b) Where fuel tanks of internal combustion engines for amusement rides are not of adequate capacity to permit uninterrupted operation during normal operating hours, the amusement ride shall be closed down and unloaded or evacuated during the refueling procedure. The fuel supply shall not be replenished while the engine is running.(c) Where an internal combustion engine for an amusement ride is operated in an enclosed area, the exhaust fumes shall be discharged to the outside.(d) Internal combustion engines for amusement rides shall be located to allow proper maintenance and shall be protected by guards, fencing or enclosure.(19)Warning Signs. (a) On rides that expose a rider to high speed, substantial centrifugal force or a high degree of excitement, the owner shall post a conspicuous warning sign at the entrance of the ride advising the public of the potential risk to riders.(b) The signs required shall be in sharply contrasting colors and be legible to a person of normal vision standing at a point of entrance to the ride.(c) The limitations shall be as specified by the manufacturer.(d) Operators and operator assistants are responsible for the maintenance of signage in or around the ride. Rides and attractions requiring signs inside each vehicle instructing riders of the safest way to ride shall be maintained at all times. If any vehicle is missing the safety signage, the ride shall not be allowed to operate unless the owner has submitted and received approval from the Department for a policy that requires the vehicle to be positively locked and tagged out to prevent inadvertent use.(e) If a sticker or on-ride signage is missing, the individual car or vehicle will be locked out utilizing a procedure that has been approved by the Commissioner or his designee. In lieu of such a program, the entire ride shall be taken "out of service" and not allowed to be operated until the proper signage is in place.Amended by Mass Register Issue 1335, eff. 3/24/2017.
