D. The Tenant and its Contractor are responsible for safety and health on the project. The Tenant and its Contractor shall conduct activities so as not to violate any safety requirements in applicable federal, State, and local regulations or the standards contained herein. The Primary Contractor shall inspect all construction and storage areas as often as necessary to be aware of conditions, and promptly take all steps necessary to prevent/remedy any unsafe or potentially unsafe conditions or activities discovered.
E. If the MAA representative becomes aware of any conditions that pose a serious or imminent danger to the health or safety of the public or MAA personnel, the MAA representative shall notify the Primary Contractor orally and send a written confirmation and request immediate corrective action. This notice, when delivered to the Primary Contractor or the Primary Contractor’s representative at the work site, shall be deemed sufficient notice of the noncompliance and that corrective action is required immediately.
F. After receiving the notice, the Tenant and its Contractor shall immediately take corrective action. If the Tenant and its Contractor fails or refuses to promptly take corrective action, the MAA may issue an order stopping all or part of the work until satisfactory corrective action has been taken.
G. At no time shall the Tenant and its Contractor be relieved of the responsibility to be aware and immediately correct any unsafe conditions. Before actual commencement of construction activity, the Primary Contractor shall, through MAA Operations, give notice, using the NOTAM system, of proposed time and date of commencement of construction as well as the length and duration of the work in such areas. Upon completion of work and return of all such areas to standard conditions the Primary Contractor shall, through MAA Operations, give notice, using the NOTAM system, of completion of construction.
H. All Contractor's vehicles that are authorized to operate on the Airport outside of the designated construction area limits or haul routes as specified and in the active Airport Operations Area shall display in full view above the vehicle a 3' x 3' or larger, orange and white checkerboard flag, each checkerboard color being square. Any vehicle operating in the active Airport Operations Area during the hours of darkness shall be equipped with a flashing amber (yellow) dome type light, mounted on top of the vehicle and of such intensity to conform to local codes for maintenance and emergency vehicles.
I. Radio communications are required between the Contractor's representative and the Air Traffic Control Tower. Radio contact is required at all times while the Contractor has personnel and equipment on the work site and while they are in an active Airport Operations Area of BWI Marshall. Radios shall be furnished by the Contractor and shall be capable of transmitting and receiving at a ground frequency of 121.9 MHZ for BWI Marshall. Sufficient radios shall be on the work site and operating at all times so that instructions or communications may be dispatched to all crews and/or equipment working in an active Airport Operations Area within one minute after receipt from the Air Traffic Control Tower.
J. Debris, waste and loose material (including dust and dirt) capable of causing damage to aircraft landing gear or propellers or being ingested in jet engines shall not be allowed on active aircraft movement areas or adjacent grassed areas. Materials observed to be within these areas shall be removed immediately and/or continuously by the Contractor during construction.
K. The Tenant and its Contractor shall furnish, at their own expense, flagmen as necessary to control their traffic in accordance with these specifications unless otherwise directed by the MAA’s representative, in which case the direction of the MAA’s representative shall be followed.
L. All Contractor's vehicles that are required to cross active runways, ramp areas, taxiways and aprons shall do so under the direct control of a competent flagman who is in direct radio contact with the Air Traffic Control Tower. All aircraft traffic on runways, ramp areas, taxiways and aprons shall have priority over Contractor's traffic. Radios shall be supplied by The Tenant and its Contractor and shall be capable of transmitting and receiving at a frequency of 121.9 MHZ for BWI Marshall.
M. Where project access requires travel on or across runways, ramp areas, taxiways, or aircraft aprons, all personnel shall keep such surfaces clear of debris. At no time shall the Contractor's vehicles or personnel be allowed to enter or cross active runways or clear zones without proper authorization obtained through ground control.
N. Open flame, welding or torch cutting operations are prohibited unless adequate fire and safety precautions have been taken and the procedure previously permitted by the MAA and the Office of the Fire Marshal.
O. Equipment and stockpiled material shall be constrained in a manner to prevent movement resulting from aircraft jet blast or wind conditions.

Materials observed to be within these areas shall be removed immediately and/or continuously by the Contractor during construction.
U. Upon completion of any stage/phase of the work the MAA will arrange a physical inspection with Airport operations personnel prior to opening for aircraft use any runway, taxiway, ramp area or Airport roadway that has been closed for work, on or adjacent thereto, that has been used for a crossing point or haul route by the Contractor.
V. Entrance to the airfield is subject to strict security regulations. All personnel entering the airfield shall obtain and display security identification badges. All vehicles shall have and display special permits issued by the Maryland Aviation Administration.
W. The Primary Contractor shall be responsible for assuring that all their employees who have unescorted access to the airfield, have background checks, including at a minimum, references and prior employment histories to the extent necessary to verify representations made by the employee relating to employment in the preceding five (5) years.
X. The smoking or carrying of lighted tobacco or other products is strictly prohibited on the airside of the Airport. Failure to comply may result in fines and/or suspension of individual security badges. If the MAA becomes aware of any conditions that pose a serious or imminent danger to the health or safety of the public or MAA personnel, the MAA representative shall notify the Tenant or its Contractor orally, with written confirmation, and request immediate initiation of corrective action. This notice, when delivered to the Tenant or its Contractor or the Contractor's representative at the work site, shall be deemed sufficient notice of the noncompliance and that corrective action is required.
