LEGAL REQUIREMENTS

This publication presents recommended practices and pre­cautions deemed pertinent to protect personnel and the pub­lic from exposure to potentially hazardous concentrations of hydrogen sulfide and sulfur dioxide. These recommended practices recognize that owners, operators, contractors, and their employees have separate responsibilities that may be contractual in nature. It is not the intent of these recom­mended practices to alter the contractual relationship(s) be­tween the parties. Some of the practices recommended herein are mandatory by local, state, or federal laws, rules, and regulations. Because of the functional and geographical diversity of these requirements, no attempt has been made in

these recommended practices to designate which are op­tional and which are required. Furthermore, even if all the practices recommended herein are followed, there still may be existing or future legally imposed laws or regulations which would not be met. In the event of any omission or conflict between these recommended practices and legally required action(s) the requirements of laws and regulations must control. Some of the federal regulations pertinent to safe production operations involving hydrogen sulfide are listed in Section 2, "References". Users of this publication shall review these regulations and other federal, state, and lo­cal laws to assure appropriate compliance in their specific operations.
