Standard Guide for In-Situ Burning of Spilled Oil: Ignition Devices

SIGNIFICANCE AND USE
4.1 This guide describes the requirements for igniting oil for the purpose of in-situ burning. It is intended to aid decision-makers and spill-responders in contingency planning, spill response, and training, and to aid manufacturers in developing effective ignition devices.  
4.2 This guide describes criteria for the design and selection of ignition devices for in-situ burning applications.  
4.3 This guide is not intended as a detailed operational manual for the ignition and burning of spilled oil.
SCOPE
1.1 This guide relates to the use of in-situ burning of spilled oil. The focus of the guide is in-situ burning of oil on water, but the ignition techniques and devices described in the guide are generally applicable to in-situ burning of oil spilled on land as well.  
1.2 The purpose of this guide is to provide information that will enable oil-spill responders to select the appropriate techniques and devices to successfully ignite oil spilled on water.  
1.3 This guide is one of four related to in-situ burning of oil spills. Guide F1788 addresses environmental and operational considerations. Guide F2152 addresses fire-resistant booms, and Guide F2230 addresses burning in ice conditions.  
1.4 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 to determine the applicability of regulatory limitations prior to use.  In particular, the storage, transport, and use of ignition devices may be subject to regulations that will vary according to the jurisdiction. While guidance of a general nature is provided herein, users of this guide should determine regulations that apply to their situation.
