Standard Guide for the Preparation of a Binary Chemical Compatibility Chart

Standard Guide for the Preparation of a Binary Chemical Compatibility Chart

SIGNIFICANCE AND USE
Various United States governmental regulations forbid incompatible materials to be transported together and require that chemical reactivity be considered in process hazard and risk analysis. A chemical compatibility chart is one tool to be used to satisfy these regulations. Binary compatibility charts are useful teaching tools in general education, in the chemical plant or laboratory, and for areas and operations where commonly performed tasks might lead to chemical mixtures such as might occur during co-shipment in compartmentalized containers, storage in a common area or compositing waste. Compatibility information is essential during process hazard reviews (for example, HAZOP). These charts may provide guidance to terminal operators on DOT HM-183 that requires that materials on adjacent compartments of multicompartment tank trucks are compatible. They provide documentation that the potential for inadvertent mixing as a potential source of heat and gas evolution from chemical reactions has been considered in sizing relief devices. Compatibility charts serve as check lists for use during process hazard reviews, and the preparation of the chart itself often brings attention to potential hazards that were previously unknown.
A binary chart only considers pairs of materials and therefore does not cover all possible combinations of materials in an operation. A common third component, for example, acidic or basic catalysts, may be covered by footnoting the potential for catalysis of a reaction between otherwise compatible materials, but the form of the chart does not ensure this. There may be reactive ternary systems that will escape detection in a binary chart.
The AIChE organization Center for Chemical Process Safety (CCPS) has recommended the use of this standard in one of their recent monographs (1). This work is currently available for free download from: http://www.osha.gov/SLTC/reactivechemicals/index.html
SCOPE
1.1 A binary chemical compatibility chart also called inter-reactivity chart, documents the hazards associated with the mixing of pairs of materials. This guide provides an aid for the preparation these charts. It reviews a number of issues that are critical in the preparation of such charts: accurate assessment of chemical compatibility, suitable experimental techniques for gathering compatibility information, incorporation of user-friendliness, and provision for revisions.
1.2 The uses of chemical compatibility charts are summarized in this standard.
1.3 This guide also reviews existing public domain compatibility charts, the differences therein, and their advantages and disadvantages.

the Preparation of a Binary Chemical Compatibility Chart
This standard is issued under the fixed designation E2012; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The purpose of this standard is to provide expert guidance to those interested in the task of
compiling chemical compatibility (inter-reactivity) charts for the purposes of process safety and
reactive chemicals hazard evaluation. This standard does not provide specific answers regarding the
inter-reactivity of specific materials. However, it does provide a detailed framework for developing
charts based on the current best practices of the chemical industry and it directs the user to sources
of reactivity information. It is the E27 Committee’s belief that inter-reactivity charts will be
increasingly used in industry for day-to-day operations, process hazard reviews, employee education,
and emergency response. It is our hope that this standard guide can be useful in that effort.

Standard Guide for Risk-Based Corrective Action

SIGNIFICANCE AND USE
4.1 The risk-based corrective action (RBCA) process presented in this guide is a consistent, streamlined decision process for selecting corrective actions at chemical release sites.  
4.2 Risk assessment is a developing science. The scientific approach used to develop the RBSL and SSTL may vary by regulatory agency and by user due to regulatory requirements, guidance and use of alternative scientifically-based methods.  
4.3 Activities described in this guide should be conducted by persons familiar with current site characterization techniques, remedial action science and technology, current human health risk and exposure assessment methodologies, toxicology, and current ecological evaluation methodologies.  
4.4 In order to properly apply the RBCA process, the user should AVOID the following:  
4.4.1 Prescribing Tier 1 RBSL or RESC as remedial action standards for all sites rather than screening levels,  
4.4.2 Limiting use of the RBCA process to Tier 1 evaluation only and not continuing with Tier 2 or Tier 3 analyses for sites where further tier evaluation is appropriate,  
4.4.3 Placing arbitrary time constraints on the corrective action process; for example, requiring that Tiers 1, 2, and 3 be completed within time periods that do not reflect the actual urgency of and risks posed by the site,  
4.4.4 Using the RBCA process only when active remedial action is not technically feasible, rather than as a process that is applicable during all phases of corrective action,  
4.4.5 Conducting active remedial action to achieve only technology-based remedial limits (for example, asymptotic levels) prior to determining applicable corrective action goals,  
4.4.6 Using predictive modeling that is not supported by available data or knowledge of site conditions,  
4.4.7 Limiting remedial action options to a single class of remedial actions for all sites (for example Guide E1943),  
4.4.8 Using unjustified or inappropriate exposure factors,  
4.4.9 Using unjustifie...
SCOPE
1.1 This is a guide for conducting risk-based corrective action (RBCA) at chemical release sites based on protecting human health and the environment. The RBCA is a consistent decision-making process for the assessment and response to chemical releases. Chemical release sites vary greatly in terms of complexity, physical and chemical characteristics, and in the risk that they may pose to human health and the environment. The RBCA process recognizes this diversity by using a tiered approach that integrates site assessment and response actions with human health and ecological risk assessment to determine the need for remedial action and to tailor corrective action activities to site-specific conditions and risks. The evaluations and methods used in the RBCA process begin with simple analyses in Tier 1 and move to more complex evaluations in either Tier 2 or Tier 3, as applicable. The process of gathering and evaluating data is conducted in a scaled fashion. Consequently, only the data that are necessary for a particular tier's decision-making are collected at that tier.  
1.2 This guide describes an approach for risk-based corrective action. It is intended to help direct and streamline the corrective action process and to complement but not to supersede federal, state and local regulations. It can be employed at sites where corrective action is being conducted including sites where there may not be a regulatory framework for corrective action, or where the user wishes to conduct corrective action such as sites in voluntary cleanup programs or under Brownfields initiatives. In addition, it can also be used as a unifying framework when several different agency programs affect the site. Furthermore, the user should be aware of the federal, state and local corrective action programs that are applicable for the site and, regardless of the program, federal, state and local agency approvals may be required to implement the proce...

Standard Guide for Collecting Treatment Process Design Data at a Contaminated Site—A Site Contaminated with Chemicals of Interest

SIGNIFICANCE AND USE
4.1 This guide allows the decision maker to determine which remedial treatment processes are and are not applicable to remediate an area of soil, surface water, or ground water that contains contaminants of concern.  
4.2 This guide provides the data to make cost comparisons of the remedial treatment processes.  
4.3 Analysis of treatment process design data can often be performed at the site with field instruments and test kits.  
4.4 Tables 1 and 2 are a guide to selecting and obtaining physical and chemical treatment process design data. Data marked with an “X” is needed to evaluate alternatives and select a remedial treatment process. Once the remedial process is selected, the additional data that are needed to design the selected remedial treatment process are marked with an “O.” It may be advisable to also collect the data marked with an “O” during the initial sampling event to minimize sampling trips to the site.  
4.5 Tables 3 and 4 list laboratory and field methods for analyzing this data. More than one analytical method may be listed. The most suitable method must be chosen for each application. (A) This table was developed jointly by the U.S. Army Corps of Engineers, Hazardous, Toxic, and Radioactive Waste Center of Expertise and the U.S. Environmental Protection Agency Technical Support Project—Engineering Forum. Additional information and methods can be found in 40 CFR 136, EPA SW-846, and Standard Methods for Evaluation of Water and Wastewater, most current edition.(B) Estimated sensitivity and detection ranges are method/kit specific. Detection ranges are estimates. Verify these methods are suitable for the samples at this site. Consult the method or manufacturer's catalogs for details.(C) Spectrometers and meters are instruments that can be used to analyze for many parameters. Kits cost much less, but usually analyze for only one parameter. There are many manufacturers of field test equipment. Verify that the field methods are applicable to the m...
SCOPE
1.1 This guide lists the physical and chemical treatment processes design data needed to evaluate, select, and design treatment processes for remediation of contaminated sites. This data is listed in Tables 1 and 2. Much of these data can be obtained and analyzed at the site with instruments and test kits.    
1.2 It is recommended that this guide be used in conducting environmental site assessments and Remedial Investigations/Feasibility Studies (RI/FS) and selections of remedy in U.S. Code of Federal Regulations 40 CFR 300.430.  
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.

Standard Guide for Risk-Based Corrective Action for Contaminated Sediment Sites

SIGNIFICANCE AND USE
4.1 This guide provides a consistent and transparent decision-making process for selecting risk-based corrective actions at sediment sites (that is, a Sediment-RBCA). Sediment-RBCA shares the same process as other RBCAs described in E1739, E2081, and E2205/E2205M but with explicit consideration of the constraints on how the available sediment assessment techniques impact decision making. Several factors exist that distinguish sediment sites from upland sites and warrant unique consideration, including background, potential for recontamination, sediment stability, sediment processes, lack of control on exposure and transport, exposure pathways and receptors, and unique site characteristics such as public lands, lack of site control on use and access. The diversity of available assessment techniques for a sediment site is considerably larger than for other media. Guidance on the technical tools themselves are described in other ASTM guides and regulatory guidance manuals.  
4.2 Sediment-RBCA incorporates the same paradigm of planning and scoping, problem formulation, exposure and effects assessments, risk characterization, and uncertainty analysis that is common to ecological and human health risk assessment guidance documents. Irrespective of terminology, both Sediment-RBCA and risk assessment share the same science-based process and share the same goal of informing risk management decisions. The specific approach used to develop risk-based human health and ecological criteria and risk-based management plans may vary from site to site based on jurisdictional requirements, site complexity, TPDs, and best professional judgment regarding the appropriate use of different assessment techniques. Some attributes of Sediment-RBCA are:  
4.2.1 Description of a tiered approach, including process flow charts, to identify critical steps and provide an overview of the entire RBCA process;  
4.2.2 Identification, development, and use of TPDs throughout the Sediment-RBCA process...
SCOPE
1.1 Sediment-RBCA is based on protecting human health and the environment. The guide supplements the RBCA (Guide E2081) and Eco-RBCA (Guide E2205/E2205M) processes and provides a decision-making process for the management of contaminated sediment. Contaminated sediment sites vary greatly in terms of setting, usage, spatial and temporal complexity, and physical and chemical characteristics; and, therefore, they also vary greatly in terms of the risk that they may pose to human health and the environment. The Sediment-RBCA recognizes this diversity by using a tiered approach for gathering and evaluating data to determine the need for additional evaluation or risk management tailored to site-specific conditions and risks.  
1.2 This guide is intended to help direct and streamline the corrective action process and to complement (but not supersede) jurisdiction-specific guidance and regulations. It can be employed where jurisdiction-specific guidance is absent or insufficiently detailed; it can also assist to unify guidance when overlapping jurisdictions apply. It is compatible with a variety of programmatic guidelines for risk assessment and guidance from US Environmental Protection Agency (USEPA), Environment Canada, European, US states, that share the underlying risk assessment approach. In all applications, regulatory agencies should be consulted, as appropriate. Sediment-RBCA is not intended to apply to current permitted releases or permit applications.  
1.3 There are numerous TPDs related to the Sediment-RBCA process. Common examples are defining DQOs, identifying relevant receptors, defining toxicity values for risk evaluation, determining target risk levels, specifying the appropriate statistics and sample sizes, determining exposure assumptions, determining when and how to account for cumulative risks and additive effects among chemical(s) of concern, addressing resource protection, along with remedial action cons...

Standard Test Method for Drying Shrinkage of Mortar Containing Hydraulic Cement

SIGNIFICANCE AND USE
4.1 This test method establishes a selected set of conditions of temperature, relative humidity and rate of evaporation of the environment to which a mortar specimen of stated composition shall be subjected for a specified period of time during which its change in length is determined and designated “drying shrinkage.”  
4.2 The drying shrinkage of mortar as determined by this test method has a linear relation to the drying shrinkage of concrete made with the same cement and exposed to the same drying conditions.4 Hence this test method may be used when it is desired to develop data on the effect of a hydraulic cement on the drying shrinkage of concrete made with that cement.
SCOPE
1.1 This test method determines the change in length on drying of mortar bars containing hydraulic cement and graded standard sand.  
1.2 The values stated in SI units are to be regarded as standard. When combined standards are referenced, the selection of measurement system is at the user’s discretion subject to the requirements of the referenced 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. Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure).2

Standard Guide for Taking Property and Behavior Measurements on Weathered Fractions of Oil

SIGNIFICANCE AND USE
5.1 A standard procedure is necessary to establish property changes for spilled oils or petroleum products at different oil weathering stages.  
5.2 This procedure employs standardized equipment, and test procedures.  
5.3 This procedure should be performed at the stages of weathering corresponding to the spill conditions of interest.
SCOPE
1.1 This guide summarizes methods to fractionate oil by evaporative weathering and then measure the properties and behavior of the weathered oil. The results of this guide can provide oil behavior data for input into oil spill models and response method selection.  
1.2 This guide covers general procedures for oil weathering and behavior and does not cover all possible procedures which may be applicable to this topic.  
1.3 The results obtained using this guide are intended to provide baseline data for the behavior of oil and petroleum products when spilled and input to oil spill models.  
1.4 The results obtained using this guide can be used directly to predict certain facets of oil spill behavior or as input to oil spill models.  
1.5 The accuracy of the guide depends very much on the representative nature of the oil sample used. Certain oils can have different properties depending on their chemical contents at the moment a sample is taken.  
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.

Standard Guide for Ecological Considerations for the Use of Oil Spill Dispersants in Freshwater and Other Inland Environments, Lakes and Large Water Bodies

SIGNIFICANCE AND USE
3.1 This guide is meant to aid response teams who may use it during spill response planning and spill events.  
3.2 This guide should be adapted to site specific circumstance.
SCOPE
1.1 This guide covers the use of oil spill dispersants to assist in the control of oil spills. The guide is written with the goal of minimizing the environmental impacts of oil spills; this goal is the basis on which the recommendations are made. Aesthetic and socioeconomic factors are not considered, although these and other factors are often important in spill response.  
1.2 Spill responders have available several means to control or clean up spilled oil. Chemical dispersants should be given equal consideration with other spill countermeasures.  
1.3 This is a general guide only. Oil, as used in this guide, includes crude oils and refined petroleum products. Differences between individual dispersants or between different oil products are not considered. The dispersibility of the oil with the chosen dispersant should be evaluated.  
1.4 The guide is organized by habitat type, for example, small ponds and lakes, rivers and streams, and land. It considers the use of dispersants primarily to protect habitats from impact (or to minimize impacts).  
1.5 This guide applies only to freshwater and other inland environments. It does not consider the direct application of dispersants to subsurface waters.  
1.6 In making dispersant use decisions, appropriate government authorities should be consulted as required by law.  
1.7 This guide does not address getting regulatory approval.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 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.  
1.10 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.
