Thebottom rows of Table 5. YES Batch chlorination; wasteneutralization2. Mitigation TechniquesMitigation refers to any design feature, system or action intended to reducethe severity of consequence of a loss event, given that an uncontrolledrelease of material or energy such as a container rupture, fire, or spill hasalready occurred.

Chemical reactivity hazards that are present Where to find hazard information, including any facility-specificcompatibility charts Any responsibility for which the affected personnel are accountable,as part of the management system Managing Chemical Reactivity Hazards Any procedure they may need to follow to safely operate the facility;such training would naturally make use of the written operatingprocedures Any additional safe work practices The use of any tools and personal protective equipment required inthe performance of their responsibilities Reporting procedures for abnormal situations, near misses, inci-dents, leaks and spills Any procedures they may need to follow to respond to or otherwiseprotect themselves in response to an emergency; such trainingshould include the use of any personal protective equipment, specialtools, or equipment required for these actions.

Corrective action tracking provides management with the status ofaudit issues and agreed-upon corrective actions. The most common and convenient way to represent binary chemicalincompatibility is by a simple two-dimensional chart or matrix. Second, there should be a review pro-cess for changes to ensure that changes to process documentation receivethe same degree of scrutiny that was applied to the original documentationpackage CCPS Occupational Safety and Health Act ofSection 5 a 1.

When conducting an investigation that may have involved uncon-trolled chemical reactions, careful and extensive sampling needs to be per-formed, including residues, unused raw materials, products, reliefeffluents, and dispersed reaction products. Backup and supporting data should be easily accessible forchart users and for easy chart updates. A partial list of extrinsic factors includes: Recommendations should be broadenough to address general causes, rather than serving only to preventrecurrence of the specific sequence of events leading to the incident.

A useful indication of a chemical reactivity hazard is the heat energy ofreaction. However,70 Managing Chemical Reactivity Hazardseducating top management is critical. Also, aluminum must be excluded from the facility as a material of con-struction in pipes, tanks, valves, pumps, and especially any container inwhich product would be transferred to a customer.

An oven temperature is increasedlinearly. The answers to Questions 7 through 11 will likely determine whetherchemical reactivity hazards are present.

The accuracy of the calcula-tion obviously depends on knowledge of the reaction products, reactionpath and the accuracy of the heat of formation data. Such equipment needs to be placed in ablast cell where it can be operated remotely.

Should such situations threaten to arise, the process knowledge man-agement system should prompt the initiation of programs to capture asmuch experience-based information as possible. Is combustion with air the onlychemistry intended? Steinbach Schering AG Dr. Financialgrants and active volunteerism are also viable options open to most organi-zations, regardless of size or resources. Development of a managementsystem will be most effective with broad input from the persons who willbe given the designated responsibilities and be held accountable to fulfillthem.

The making of an off-specifica-tion product is often treated as a quality problem; however, it may also bean indicator of a chemical reactivity near miss.

Can incompatible materials coming intocontact cause undesired consequences,based on the following analysis? Sax isalso available in electronic format Lewis Management of change programs must pre-serve and keep the base record current and protect against degradation orelimination of safety features, including such measures as maximumintended inventories and passive protection systems.


They can beaccessed from the U.

Essential Practices for Managing Chemical Reactivity Hazards – [RAR Document]

In other cases, thelimits will need to be developed through combination of reactivity infor-mation discussed in Sections 4. The possible hazard level as a resultof exothermic chemical reactions is identified with a series of physical and chemical parametersthat are characteristic for the reactants and equipment parameters.

Therefore, the technical basis needs to bedocumented, including the WHYs. Risk con-trol strategies in the first two categories, inherent and passive, are consid-ered more reliable because they depend on the physical ankage chemicalproperties of the system rather than the successful operation of instru-ments, devices, procedures, and people. Audits can help Managing Chemical Reactivity Hazardsensure that compliance is being achieved with a sound process safety pro-gram, and that risks are being appropriately managed.

Since they only address the likeli-hood of undesired events, these methods are often combined with conse-quence severity calculations in a quantitative risk analysis, as described byCCPS b. annlage

The same applies in respectof the measures concerning the failure mode which leads to a reduction in the solvent quantityD. The effects on the reaction kinetics and rates of heat generationand gas evolution need to be investigated. The repackaging exam-ple in Section 5.

The definition of categories for the chart is an important part ofconstruction. The person, team, or adhoc committee who is initially facilitating the setting up of the manage-ment system should begin preparations by gaining an understanding ofthe basic principles and priorities of chemical reactivity hazards. The chart can then be made accessible via a network server toall those involved in a common operation. Inten-tional chemistry is also likely being practiced in alage waste treatmentfacility.
