1.1 本规程涵盖与施工、维护、维修、清洁、切割和拆除工作相关的行业通常使用的所有类型的压力水射流清洗和切割设备的正确操作的人员要求、操作员培训、操作程序和推荐的设备性能/设计。 1.2 术语“高压水喷射”涵盖所有水喷射，包括在100.5 psig（0.69 MPa）以上的压力下使用添加剂或磨料。 1.3 任何需要操作或维护压力水喷射设备的人员均应经过培训，并证明其具备按照原始设备制造商的说明、规范和培训计划操作或维护压力水喷射设备的能力和知识。 1.4 以英寸-磅为单位的数值应视为标准值。 括号中的值仅供参考。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 看见 3.2.3 , 4.4 , 5.7.2 , 5.11 , 5.14 , 6.2 , 6.7 、和截面 8. 和 11 具体危害声明。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本规程旨在为压力水射流清洗和切割设备的正确操作提供指导。 4.2 这种做法也适用于可预见受伤风险的较低压力。 4.3 本规程旨在帮助不熟悉喷水清洗和切割设备操作的人员学习正确使用设备。 4.4 正确操作和使用压力水射流清洗和切割设备需要操作员根据原始设备制造商的规范、说明和编程教学材料熟悉压力金属配件、软管、枪和附件的标识；只有到那时才能开始水力喷射。未经设备制造商事先书面批准，不得修改喷水设备。 应指导员工识别和避免本手册中确定/要求的不安全条件 5.18 . ( 警告- 误用喷水设备和使用不当的配件、软管或附件可能会造成严重伤害。） 4.5 使用压力水射流设备进行切割和清洁是一项快速发展的技术。至少每五年对本惯例进行一次定期审查，以确定是否有任何必要的变更。

1.1 This practice covers the personnel requirements, operator training, operating procedures, and recommended equipment performance/design for the proper operation of all types of pressure water-jet cleaning and cutting equipment as normally used by industries concerned with construction, maintenance, repair, cleaning, cutting, and demolition work. 1.2 The term “high-pressure water jetting” covers all water jetting, including the use of additives or abrasives at pressures above 100.5 psig (0.69 MPa). 1.3 Any person required to operate or maintain pressure water-jetting equipment shall have been trained and have demonstrated the ability and knowledge to do so in accordance with the original equipment manufacturer's instructions, specifications, and training programs. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See 3.2.3 , 4.4 , 5.7.2 , 5.11 , 5.14 , 6.2 , 6.7 , and Sections 8 and 11 for specific hazards statements. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This practice is intended to provide guidance on the proper operation of pressure water-jet cleaning and cutting equipment. 4.2 This practice is also applicable at lower pressures where there is foreseeable risk of injury. 4.3 This practice is provided to assist persons unfamiliar with the operation of water-jet cleaning and cutting equipment in learning to correctly use the equipment. 4.4 Correct operation and use of the pressure water-jet cleaning and cutting equipment requires that the operator has familiarized himself with the identification of pressure metal fittings, hoses, guns, and accessories in accordance with the original equipment manufacturer’s specifications, instructions, and programmed instructional material; only then shall hydrojetting begin. Modification of water-jetting equipment shall not be done without prior written approval by the manufacturer of the equipment. Employees shall be instructed in the recognition and avoidance of unsafe conditions as identified/required in 5.18 . ( Warning— Serious harm or injury may result from the misuse of water-jetting equipment and the use of improper fittings, hoses, or attachments.) 4.5 The use of pressure water-jet equipment for cutting and cleaning is a rapidly evolving technology. This practice will be periodically reviewed for any required changes at least every five years.
