4.1 Significance—Dried blood represents a significant challenge to cleaning surgical instruments. The water-soluble components of blood are easily rendered insoluble when exposed to heat, chemical solutions, or time at room temperature. The water insoluble component of blood is fibrin built up during coagulation. These proteins bind quite readily to the surfaces of surgical instruments making them difficult to remove even with the aid of chemical cleaning agents. Instruments contaminated with blood residue after reprocessing represent a significant threat for infection to healthcare workers and patients. Healthcare facilities typically employ the use of automated instrument washers. These devices combine mechanical action along with chemical cleaning agents in a staged cleaning cycle designed to thoroughly clean surgical instruments. To function properly, these machines must be performing at targeted mechanical efficiency and deliver the correct chemical cleaning agents at the correct temperature, at the correct dosage for the correct period of time. Manufacturers of automated washers and manufacturers of cleaning detergent need to evaluate the performance of their products utilizing a surrogate for surgical instruments soiled with blood. The results of the performance testing will be used to improve product design and for validation of the performance of their product for various regulatory requirements.4.2 Use—The regular, periodic use of the blood soil test is a systemic challenge to the functioning of an automated washer. To properly challenge the cleaning device, the test must be analogous to the dried blood soil, to the stainless steel substrate, and to the physical barriers presented by surgical instruments. These physical barriers include the box lock, or pivot joint of a hinged instrument, the serrated tips, and crevices of surgical instruments. On the test coupon, the components of blood are similar to the state of dried blood on instruments. By utilizing a grooved stainless steel coupon, the substrate is similar to that of stainless steel instruments. By mounting the soiled coupon in a plastic holder the physical barriers represented by cracks and crevices of instruments (for example, box locks) are represented. Users are provided with an interpretation guide that aids them in interpreting results that are less than optimal. For instance, failure to remove the fibrin layer of blood soil (which is water insoluble) indicates a problem with the chemical cleaning agent(s). Failure to evenly remove a hemoglobin soil indicates a mechanical failure. Failure to remove any soil indicates either a catastrophic mechanical failure, or inappropriate settings for the initial rinse stage. As a standardized challenge, the test provides a reproducible means for the washer manufacturer and the detergent manufacturer to compare new designs and formulations to those existing within their own product line as well as those of others in the market. For the purpose of submitting their instructions for use, the test provides a means to validate the performance of their product with a device that is a surrogate for the devices their products will be used to clean in the practical setting. This validation testing can be used as part of any necessary documentation for regulatory filings and records.1.1 This guide is based on a standardized test soil correlating to coagulated blood suitable for screening tests and the evaluation of the cleaning efficiency of washer-disinfectors used for reprocessing of surgical instruments. This guide strictly deals with cleaning and does not describe any methods that are related to disinfection. See Referenced Documents D5343, D4008, D4265, D2960, and D3050 in Section 2 for additional information.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

3.1 One of the key considerations in making sound cleanup decisions for oiled shorelines is the relative sensitivity of the impacted area. Some areas are very sensitive and certain cleaning methods could cause more harm than benefit. In such cases, natural recovery will be the preferred approach. In other cases, depending on the type of oil, the amount of oil present may be so extensive that recovery will be significantly delayed or not occur at all unless active intervention is carried out.3.2 This guide presents summary information taken from publications listed in Section 2 on the relative physical and biological sensitivities of shorelines for coastal and inland habitats. Use this guide together with the referenced publications and ASTM guides to make informed decisions prior to undertaking cleaning operations. Consult appropriate government agencies according to law.3.3 The relative sensitivities of shorelines and resources relate to a number of factors:3.3.1 Shoreline type (substrate, grain size, tidal elevation, etc.),3.3.2 Biological productivity, diversity and vulnerability,3.3.3 Exposure to wave and tidal energy, and3.3.4 Ability to conduct cleanup without further damage.1.1 This guide provides information on shoreline types and sensitive habitats that can be used as guidance for selecting appropriate cleaning techniques following an oil spill. This guide does not address protected archaeological, historical, or cultural sites.1.2 This guide’s emphasis is on typical physical and biological attributes of coastal and inland habitats that could be at risk from oil spills. It reviews and encompasses the entire spectrum of shoreline types representing a wide range of sensitivities. It is largely based on NOAA’s and API’s publications listed in Section 2.1.3 This guide provides only very broad guidance on cleaning strategies for the various habitats. For more in-depth guidance, the reader is referred to Section 2, Referenced Documents.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.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.
