2.1.4 SAFETY REGULATION COMPLIANCE: The contractor shall comply with standard OSHA and RIA safety standards, including conforming to confined space work requirements when applicable.

2.1.5 SAFETY LOCKOUTS: Each point of first connection shall be designed and constructed to allow the utility to be completely isolated from the equipment. This isolation shall be insured by application of a standard key locking padlock. The device(s) shall only be lockable in the de-energized (OFF) condition.

2.1.6 LOSS OF PRESSURE: Hydraulic and pneumatic circuits shall be designed such that loss of pressure, or pressure surges, shall not cause a hazard. Means shall be provided to prevent operation of the equipment with insufficient pressure, if such operation could cause a hazard.

2.1.7 TRAPPED ENERGY: Means shall be provided for the controlled release of stored energy. This energy may be in the form of, but not limited to, air and hydraulic pressure accumulators, capacitors, springs, counter balances and flywheels. When appropriate, a label shall be affixed to the stored energy source to identify the hazard.

2.1.8 REAL ID: Starting 03-MAY-2023 all personnel entering Rock Island will be required to show a Real ID form of identification.

2.1.9 AUDIBLE NOISE: The equipment noise level during normal operation shall not exceed 85-dbs, “A” scale. Tests shall be conducted around the entire equipment 60-in to 65-in above the floor within 3-ft of any major sound source. Metal removal equipment shall comply with the standard noise requirement while making a midrange horsepower cut on rigidly clamped mild steel. The contractor shall furnish shields, baffles, enclosures, or other devices necessary to bring the equipment into conformance. Any such device shall not interfere with the proper operation of the equipment and shall be designed to preserve the visibility necessary for safe operation of the system.

3. APPROVAL/SHIPPING

3.1 Shipping

3.1.1 RESPONSIBILITY: The contractor is responsible for delivery of the equipment to the RIA. Adequate preserving of equipment surfaces, packing, marking, and skidding of materials for shipment shall be the responsibility of the contractor. If special lifting devices, such as hooks or eyes, are required for ease of handling, they shall be supplied with the equipment. Any special devices shall be returned to the contractor upon request only if they will not be required for future movement of the equipment, and at the contractor’s expense.

3.1.2 SHIPPING SCHEDULE: Be aware, the RIA will only off-load equipment arriving between 7:00 am and 12:00 am (noon), local time on Mondays through Thursdays except holidays.

3.1.4 ARRIVAL INSPECTION: Upon receipt of equipment at RIA, a preliminary inspection shall be performed to determine condition and/or count. This inspection shall be performed by Rock Island Arsenal personnel.

3.2 Installation

3.2.1 OFF-LOADING/PLACEMENT: RIA will perform the off-loading and placement of the equipment.

3.2.1.1 Any special requirements or precautions to be observed shall be the responsibility of the contractor to provide.

3.2.1.2 The contractor or his representative may be present during this process; however, such person will be responsible for being present upon arrival of the equipment at RIA. Off-loading and placement shall not be delayed to allow arrival of the contractor or his representative.

3.2.2 LIABILITY: In any case, the equipment remains the property of the contractor, and the contractor shall assume all responsibility and liability for the equipment and the work performed upon it. The government shall be held harmless for any damage done to the equipment at any time up until final acceptance of the equipment by RIA, except in the case of intentional damage and/or gross negligence on the part of RIA personnel.

3.2.3 UTILITY CONNECTION: Equipment supplied to the RIA will have single point shut-off for each utility supplied to a system. This means that equipment constituting a single system shall be wired to a single main electrical disconnect point, plumbed to a single pneumatic shut-off valve, etc… This will be referred to as the “point of first connection”. Each type of power source may have only one point of first connection. E.g. (1) pneumatic shut-off valve, (1) water supply shut-off valve, (1) electrical disconnect, etc… Each point of first connection shall be clearly labeled on the system and shown in the safety lockout portion of the documentation package. These points must be located on a stationary component and positioned such that they will not create a hazard to personnel during normal operation of the system. The first connection points shall be accessible from the shop floor without the use of ladders, steps, or stools. Access cannot be hampered by operation of the system.

3.2.4 UTILITIES AVAILABLE: RIA shall be responsible for providing the following:

3.2.4.1 Connection of 460-V, 60-Hz, 3-Ph AC electrical power to the fused or breaker type disconnect switch required in the ELECTRICAL DISCONNECT paragraph of this purchase description. Connection does not include filters, surge protection, or any peripheral equipment necessary to make the equipment functional.

3.2.5 ELECTRICAL DISCONNECT: The equipment shall be equipped with a manual, fused or breaker type disconnect switch, readily accessible to the operator, which will deactivate the entire equipment. It shall be located no more than 6-ft 7-in from the floor to the highest point the control device. It shall be capable of being locked in the de-energized state (OFF) only.
