4.1 This guide is meant to aid local and regional spill response teams during spill response planning and spill events.1.1 This guide addresses in-situ burning as a response tool for oil spills occurring on waters with ice present.1.2 In-situ burning is one of several methods available to responders for the control or cleanup of spilled oil, which includes mechanical recovery, dispersant application or natural recovery.1.3 The purpose of this guide is to provide the user with general information on in-situ burning in ice conditions as a means of controlling and removing spilled oil. It is intended as a reference to plan an in-situ burn of spilled oil.1.4 This guide outlines procedures and describes some equipment that can be used to accomplish an in-situ burn in ice conditions. The guide includes a description of typical ice situations where in-situ burning of oil has been found to be effective. Other standards address the general guidelines for the use of in-situ burning (Guide F1788), the use of ignition devices (Guide F1990), the use of fire-resistant boom (Guide F2152), the application of in-situ burning in ships (Guide F2533), and the use of in-situ burning in marshes (Guide F2823).1.5 In making in-situ burn decisions, appropriate government authorities should be consulted as required by law.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.Specific precautionary information is given in Section 8. Guide F1788 addresses operational considerations.1.8 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.

4.1 This guide describes a method of determining the buoyancy to weight ratio of spill response booms. The principle is based on Archimedes Law, which states that a body either wholly or partially immersed in a fluid will experience an upward force equal and opposite to the weight of the fluid displaced by it.4.2 Unless otherwise specified, when used in this guide, the term buoyancy to weight ratio (B/W ratio) refers to the gross buoyancy to weight ratio. Buoyancy is an indicator of a spill response boom’s ability to follow the water surface when exposed to current forces, fouling due to microbial growth (which adds weight), and wave conditions. Surface conditions other than quiescent will have an adverse effect on collection or containment performance. When waves are present, conformance to the surface is essential to prevent losses. Minimum buoyancy to weight ratios for oil spill containment booms are specified in Guide F1523 for various environmental conditions.4.3 This guide provides the methodology necessary to determine the buoyancy to weight ratio using a fluid displacement method. This method is typically applied to booms having relatively low B/W ratios (in the range of 2:1 to 10:1). Booms with greater buoyancies may also be tested in this manner. It is acceptable to use calculation methods to estimate boom displacement for booms with buoyancies greater than 10:1, where the potential error in doing so would have a less significant effect on performance.4.4 When evaluating the B/W ratio of a spill response boom, consideration must be given to the inherent properties of the boom that may affect the net B/W ratio while in use. These considerations include, but are not limited to, absorption of fluids into flotation materials, membranes that are abraded during normal use, and entry of water into components of the boom.The entry of water into boom components is of particular concern with booms that contain their flotation element within an additional membrane. (This is the case for many booms that use rolled-foam flotation and relatively lightweight material for the boom membrane.) It is also important for booms that have pockets that enclose cable or chain tension members or ballast. When new, the membrane enclosure may contain air that would result in increased buoyancy. In normal use, the membrane material may be easily abraded such that it would no longer contain air, and water would be allowed in at abrasion locations. For such booms, the membrane enclosure shall not be considered as part of the flotation of the boom, and the membrane shall be intentionally punctured to allow water to enter during the test procedure.1.1 This guide describes a practical method for determining the buoyancy to weight (B/W) ratio of oil spill containment booms.1.2 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.1.3 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.

4.1 The performance criteria listed in this guide will provide guidance in the selection of oil spill pumping equipment.4.2 This guide has been developed for use by the following: manufacturers of pumping systems who wish to establish a common means of evaluating and reporting the performance characteristics of their products; and existing or potential users of pumping systems who wish to compare the performance characteristics of various products.1.1 This guide is intended as a guideline for the standardized reporting of performance data of pumps and pump systems that may be considered for use in oil spill response operations. The present objective is to develop a reporting guideline to aid in the comparative evaluation of various devices.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.3 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.1.4 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.
