1.1本规程涵盖了报告和记录水上油和相关活动和现象的视觉观察结果的方法。 1.2本规程仅适用于从飞机或直升机上目视观察水面上的油。虽然可以使用一组类似的代码对海滩上的石油进行分类，但本实践中不讨论此主题。它不包括飞机遥感设备的使用，这在单独的标准中讨论。 1.3本规程适用于各种环境和地理情况下的所有类型的油。 1.4从空中目视观察水上油污涉及与飞机或直升机在低空运行相关的许多安全问题。本实践中未涉及这些问题，但观察员应意识到此类操作的危害。 1.5本标准无意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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 监督和跟踪人员可以使用这种做法向视觉观察的客户报告视觉观察结果。这些观测数据将为绘制浮油位置图提供依据。 本规程提供了一种程序，用于以系统的方式和通用格式报告水上石油的视觉观察，该格式易于被视觉漏油观察地图的观察者和用户理解。 本规程涉及在使用目视观察方法时，油以外的材料可能与油混淆的可能性。

1.1 This practice covers methods of reporting and recording visual observations of oil on water and related activities and phenomena. 1.2 This practice applies only to visual observations of oil on water from an airplane or helicopter. While a similar set of codes could be used for classifying oil on beaches, this subject is not discussed in this practice. It does not cover the use use of remote-sensing equipment from aircraft, which is discussed in a separate standard. 1.3 This practice is applicable for all types of oil under a variety of environmental and geographical situations. 1.4 Visual observations of oil on water from the air involve a number of safety issues associated with the operation of airplanes or helicopters at low altitudes. These are not dealt with in this practice, but the observer should be aware of the hazards of such operations. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This practice can be used by surveillance and tracking staff to report visual observations to the clients of visual observations. The data produced from such observations will provide the basis for preparing maps of the oil-slick location. This practice provides a procedure for reporting the visual observation of oil on water in a systematic manner and in a common format that can be readily understood by both observers and users of visual oil-spill observation maps. This practice deals with the possibility that materials other than oil might be confused with oil when using visual observation methods.
