        No Seller or lower-tier subcontractor contracting for any part of the Purchase Order work which may require or involve the employment of laborers or mechanics (see Federal Acquisition Regulation (FAR) 22.300) shall require or permit any such laborers or mechanics in any workweek in which the individual is employed on such work to work in excess of 40 hours in such workweek unless such laborer or mechanics receives compensation at a rate not less than 1-1/2 times the basic rate of pay for all hours worked in excess of 40 hours in such workweek.
    (B)    Violation; Liability for Unpaid Wages; Liquidated Damages.
        In the event of any violation of the provisions set forth in paragraph A. of this clause, the Seller and any subcontractor responsible therefore shall be liable for the unpaid wages.  In addition, such Seller and subcontractor shall be liable to the United States (in the case of work done under contract for the District of Columbia or a territory, to such District or to such territory), for liquidated damages.  Such liquidated damages shall be computed with respect to each individual laborer or mechanic employed in violation of provisions set forth in paragraph A. of this clause in the sum of $10 for each calendar day on which such individual was required or permitted to work in excess of the standard workweek of 40 hours without payment of the overtime wages required by provisions set forth in paragraph A. of this clause.
    (C)    Withholding for Unpaid Wages and Liquidated Damages.
        The Contracting Officer shall upon his or her own action or upon written request of an Authorized Representative of the Department of Labor withhold or cause to be withheld, from any monies payable on account of work performed by the Seller or subcontractor under any such Purchase Order or any other Federal contract with the same Prime Contractor, or any other Federally-assisted contract subject to the Contract Work Hours and Safety Standards Act which is held by the same Prime Contractor, such sums as may be determined to be necessary to satisfy any liabilities of such Seller or subcontractor for unpaid wages and liquidated damages as provided in the provisions set forth in paragraph B. of this clause.

    (a)    During the term of this contract, the Contractor agrees to post a notice, of such size and in such form as the Secretary of Labor may prescribe, in conspicuous places in and about its plants and offices, including all places where notices to employees are customarily posted.  The notice shall include the following information (except that the last sentence shall not be included in notices posted in the plants or offices of carriers subject to the Railway Labor Act, as amended (45 U.S.C. 151-188)).

Notice to Employees
    Under Federal law, employees cannot be required to join a union or maintain membership in a union in order to retain their jobs.  Under certain conditions, the law permits a union and an employer to enter into a union-security agreement requiring employees to pay uniform periodic dues and initiation fees.  However, employees who are not union members can object to the use of their payments for certain purposes and can only be required to pay their share of union costs relating to collective bargaining, contract administration, and grievance adjustment.
    If you believe that you have been required to pay dues or fees used in part to support activities not related to collective bargaining, contract administration, or grievance adjustment, you may be entitled to a refund and to an appropriate reduction in future payments.
    For further information concerning your rights, you may wish to contact either a Regional Office of the National Labor Relations Board or:  National Labor Relations Board, Division of Information, 1717 Pennsylvania Avenue, NW, Washington, DC  20570.
    (b)    The Contractor will comply with all provisions of Executive Order 12800 of April 13, 1992, and related rules, regulations, and orders of the Secretary of Labor.
    (c)    In the event that the Contractor does not comply with any of the requirements set forth in paragraphs (a) or (b) of this clause, this contract may be cancelled, terminated, or suspended in whole or in part, and the Contractor may be declared ineligible for further Government contracts in accordance with procedures authorized in or adopted pursuant to Executive Order 12800 of April 13, 1992.  Such other sanctions or remedies may be imposed as are provided in Executive Order 12800 of April 13, 1992, or by rule, regulation, or order of the Secretary of Labor, or as are otherwise provided by law.
    (d)    The Contractor will include the provisions of paragraphs (a) through (c) in every subcontract or purchase order entered into in connection with this contract unless exempted by rules, regulations, or orders of the Secretary of Labor issued pursuant to section 3 of Executive Order 12800 of April 13, 1992, so that such provisions will be binding upon each subcontractor or vendor.  The Contractor will take such action with respect to any such subcontract or purchase order as may be directed by the Secretary of Labor as a means of enforcing such provisions, including the imposition of sanctions for noncompliance; provided, however, that if the Contractor becomes involved in litigation with a subcontractor or vendor, or is threatened with such involvement, as a result of such direction, the Contractor may request the United States to enter into such litigation to protect the interests of the United States.

163.    EXCLUSION OF MERCURY (ELECTRONICS) (NAVSEA) (SEP 1990)
    (EB-MODIFIED) (MANDATORY)
    (a)    Supplies furnished shall contain no free mercury (metallic form) or mercury compounds (e.g. mercuric oxide and mercuric chloride) without written approval of the Naval Sea Systems Command (NAVSEA).
       NOTE:    The Seller shall perform a review to the extent necessary to obtain reasonable assurance that mercury is not being used in the supplies (e.g. review of drawing parts lists and material lists)
    (b)    Mercury bearing instruments and equipment (i.e. those instruments and equipment containing free mercury) shall not be used in the manufacture, fabrication, assembly, testing, etc., of any supplies.
    NOTE:
        (1)    The most probable causes of mercury contamination are direct connected manometers, mercury vacuum pumps, mercury seals, mercury-in-glass thermometers, or handling free mercury in the immediate vicinity of supplies.
        (2)    The Seller shall perform a review of his facilities to provide reasonable assurance that supplies are not in danger of mercury contamination (e.g. check of instruments and test equipment).
        (3)    In case of doubt or question of manufacturing procedures, equipment, or instruments regarding mercury, contact NAVSEA via Buyer  for assistance.
        (4)    In the event of any accident involving mercury contamination or suspicion of such contamination of supplies, NAVSEA shall be notified immediately via Buyer.

    (EB-MODIFIED) (MANDATORY)
    (a)    The supplies furnished under this Purchase Order shall contain no metallic mercury or mercury compounds and shall be free from mercury contamination (i.e. during the manufacturing process, tests, or inspections, the supplies offered shall not have come in direct contact with mercury or any of its compounds nor with any mercury containing devices employing only a single boundary of containment.  (A single boundary of containment is one which is not backed by a second seal or barrier to prevent contamination in event of rupture of the primary seal or barrier.))  Mercury contamination of the supplies will be cause for rejection of the material.
    (b)    If there is reasonable cause to suspect the supplies of being contaminated by mercury, the following test may be used to determine whether contamination by metallic mercury exists: Enclose the equipment in a polyethylene bag or close-fitting air-tight container and place in an oven at 125 deg.  F+ 5 deg. F for one hour.  Sample the trapped air and if mercury vapor concentration is 0.01 mg/cu meter or more, the material is mercury contaminated insofar as the requirements of this contract are concerned.  Mercury vapor concentration can be determined with a mercury vapor detector such as a portable General Electric Vapor Detector (catalog number 8257557G-3), Beckman Instrument Model K-23, or other instruments that have equivalent range and capabilities.  It should be noted that certain vapors such as benzene interfere with this type of mercury vapor detector  and that the detector should never be zero adjusted in any suspect atmosphere.
    (c)    If the inclusion of metallic mercury or mercury compounds is required as a functional part of the material furnished under this contract, the Seller shall obtain written approval from the Naval Sea Systems Command (NAVSEA) via Buyer before proceeding with manufacture.  The Seller's request shall explain in detail the requirements for mercury; identify specifically the parts to contain mercury; and explain the method of protection against mercury escape.  Such a request will be forwarded via Buyer to the Government Inspector or Government Representative with a copy to NAVSEA.  Upon approval by NAVSEA, the Seller will provide a "Warning Plate" as prescribed by NAVSEA which will include a statement that mercury is a functional part of the item and will include name and location of that part.
    (d)    If and to the extent that this Purchase Order calls for work to be performed by the Seller or its subcontractor on a submarine or in the nuclear plant of a surface ship, the Seller or its subcontractors, in connection with such work, shall not bring into or utilize in the submarine or nuclear plant of surface ship any equipment, instrument or other device containing metallic mercury or mercury compounds, unless such equipment, instrument or device has been approved by NAVSEA or its authorized representative for use in submarine and/or nuclear plants of surface ships.
    (e)    The Seller is required to certify:
        (1)    The supplies furnished under this Purchase Order contain no metallic mercury or mercury compounds; and
        (2)    The Seller has taken reasonable steps to ensure that the supplies furnished under this contract are not contaminated with metallic mercury or mercury compounds.
    (f)    These requirements shall be included in all subcontracts hereunder.

165.    CARCINOGENS PROHIBITED - CONDITIONAL ACCEPTANCE OF     CERTAIN MATERIALS
