Eduardo Arosemena Muñoz COMMONWEALTH OF PUERTO Secretary for Services DEPARTMENT OF LABOR AND HUMAN RESOURCES Office of the Secretary Hato Rey, Puerto Rico RESOLUTION I, Miguel Romero Lugo, Secretary of Labor and Human Resources, pursuant to the authority conferred by Section 8 of the Puerto Rico Occupational Safety and Health Act, Number 16 of August 5, 1975 as amended (29 LPRA 361 et. seq.), hereby amend the Puerto Rico Occupational Safety and Health Regulation, Number Four (Part 1910) by adopting the following federal rule: PART 4 OSH 1910 Electrical Standard; Clarifications; Corrections; Final Rule 73 FR, No. 210, (64202-64205), October 29, 2008 The Occupational Safety and Health Administration (OSHA) takes into consideration this questions and makes a change in the regulatory text of the disposition in order to clarify OSHA's position regarding its scope. The change made will not alter in any way the substantive obligations of the affected parts. In addition, OSHA is correcting two typographical errors found in table S-3 of the final rule. We recommend the adoption of this regulation in the federal register, in order for us to have the same date of effectiveness as that of the Federal Government (October 29 2008). For this reason, we can protect our workers with the latest changes in the field of electricity. This regulation is going to be cited as "4 OSH 1910", instead of "29 CFR 1910". Please provide this information in the adopting resolution.
