§ 33.66. Safety glazing in railroad equipment.

 (a)  Every railroad over which the Commission has jurisdiction, operating within this Commonwealth, shall provide safety glazing in all windows and doors in lieu of other glazing in all cars, cabin cars and locomotives used in the transportation of passengers and employes of the company, including those engaged in the operation of the equipment.

 (b)  ‘‘Safety glazing material,’’ as used in this section, shall be construed to mean any glass or transparent product manufactured or fabricated in such manner as substantially to prevent shattering and flying of the glass or transparent product when struck or broken, and which is approved by the Commission for use in appropriate locations.

 (c)  One third of all equipment, to which this section applies, of each railroad shall be in compliance with the provisions of this section on or before July 31, 1975; 2/3 of such equipment shall be in compliance by July 31, 1976; and the remaining equipment shall be so equipped on or before July 31, 1977; in any event equipment not in compliance shall not be operated within this Commonwealth after July 31, 1977.

 (d)  Glazing material used in automotive-type railroad equipment designed for use on land highways shall be in conformance with Federal Rules and Regulations—49 CFR Part 571 (relating to Federal motor vehicle safety standards).

 (e)  The minimum standards for glazing material used in railroad equipment, other than automotive-type equipment designed for use on land highways, shall be standards described in USAS Z26.1-1966 and in Underwriters Laboratories Standard for Safety UL 972 insofar as it has been adopted as American National Standard designated ANSI SE4.5-1972, with exceptions as noted and for use in locations as set forth in subsection (f).

 (f)  Reference should be made to the Table 1-Page 11-Grouping of Tests-USAS Z26.1 and numbered paragraphs on pages dated June 2, 1972 ANSI SE4.5-1972:

   (1)  Safety Glazing Material for use in windshields for locomotives, railroad equipment and engineman’s compartments of multiple unit cars. Glazing material for use in windshields shall have minimum properties as determined by tests listed in Item 1, Table 1 USAS Z26.1-1966.

   (2)  Safety Glazing Material for use in side windows of locomotives, railroad equipment, engineman’s compartments of multiple unit cars and in cabin cars. Glazing materials for use in side windows shall have minimum properties as determined by tests listed in Item 4, Table 1 USAS Z26.1-1966, with the following exceptions:

     (i)   Rigid plastic material may be coated.

     (ii)   In lieu of the ball impact test in Item No. 4 USAS Z26.1 the material shall be qualified under Test No. 4 Multiple Impact Test; Test No. 5 Thermal Conditioning Test for Outdoor Use; and Test No. 7 High-Energy Impact Test as described on Pages 5, 6 and 7 dated June 1972 of ANSI SE4.5-1972.

     (iii)   That material shall be tested for abrasion resistance by testing in the manner described in Test No. 17 USAS Z26.1 except the specimens shall be subjected to abrasion for 300 cycles and the results interpreted on the basis of the arithmetic mean of the percentages of light scattered by the three abraded specimens not exceeding 5.0%.

   (3)  Safety Glazing Material for use in passenger car windows and doors except for engineman’s compartments in multiple unit cars. Glazing materials for use in windows and doors shall have the minimum properties as determined by tests listed in Items 3 or 5-Table 1 USAS Z26.1 except that rigid plastics may be coated and shall show abrasion resistance as described in paragraph (2)(iii).

   (4)  Marking. Marking of safety glazing material shall be in accordance with Paragraph 6 USAS Z26.1 and Paragraph 8 on Page 7 dated June 1972 of ANSI SE4.5-1972.
