It is fully recognized that having a management system in place thatmatches all of the items in Table 4. Administrativeprocedures and control limits are not always documented with adequateexplanation of their underlying basis. Is any heat generated during the mixingor physical processing of substances? Over the years, many things happen in a plant that are not written down,but the ability to relate nalage questions or problems to past experience is anlagge to effective problem solving.
The team must be able to systematically identify abnormal situationsinvolving chemical reactivity, estimate the likelihood of each abnormal sit-uation occurring, and assess the consequences of each situation if it contin-ues uncontrolled.
Learning from near misses is much less costly thanlearning from loss events. You are then responsi-ble to provide your employees and customers with material safetydata.
Consequently Texo cannot be reached through nalage heating. Interpreting Screening DataThe selection and use of testing equipment alnage procedures, and particu-larly the interpretation of the results, requires competent people.
A spreadsheet program can be used to capture and display the chartinformation. Communication with contract personnel and broader outsourced manu-facturing issues are addressed by Early and CCPS The attributes of a managementsystem listed in Table 4.

Many other attorneys see this as an important exercise in demon-strating the companys affirmative action in trying to understand andmanage risks. Major reaction energy releases are to be anticipated if the reaction re-initiates. Combustor ExampleReferring to the questions in Chapter 3, Question 1 Is intentional chemis-try performed at your facility?
If more severe consequences than a leaking railcar were found, theneven greater precautions would likely be warranted. Combining materials, intentionally or inadvertently, maycreate a reactive mixture with properties not described on any indi-vidual MSDS.
Thebottom rows of Table 5. The line referred to here is the chain of command and authoritythat extends from the operator to the chief executive officer of the com-pany. Temperatures are closely monitored, andstack emissions are routinely sampled. Avoid using blanks empty cells incompatibility charts since blanks may indicate that there is no hazard, or simply that thehazard is unknown.
Larger corporations or industrygroups may also have the resources to sponsor research into the under-standing and controlling of chemical reactivity hazards.
MSDSs should be available from material suppliers. The authority having jurisdiction, which initiated the preparation of this guideline, andauthor s assume no liabilities with respect to the multiplication or reproduction of this guideline.
Continuous monitoring of the temperature and pressure outputsfrom a sample tube in the oven provides qualitative information about thethermal characteristics of the sample. The team must also be able to come to a consensus onwhere existing safeguards are inadequate and where risk control actionsare needed.
Question 5 Is combustion with air the only chemistry intended atyour facility? For all training and communications, keep in mind: In the paragraphs that follow, brief descriptions of some chemical reactiv-ity test methods are given, after HSE Use and implementation of this guideline is the sole responsibility of the user and noclaims, as a result of possible consequences, can be made against the author s or theauthority having jurisdiction or the translator.
Is any substance identified as peroxideforming? Safety PolicyThe process of hazard management begins with management support,commitment, and action. They mustdetermine what methods best fit into the particular culture and perspectiveof their organization.
Ineffective recommendationscan serve to merely transfer the risk or even to create a new hazard that wasnot present before the initial incident. In practice, conflicts of interestmay arise between safety and other goals such as production demands andbudgets. Dividing Responsibility for Oversight Process versus Plant versus Corporate Multiple facilities in an organization may have similar chemical reactivityhazards; similar storage, handling or processing operations; or use similartechnologies to control the associated hazards.
Specific practices that relate to the nature of chemicalreactivity hazards are discussed below. Review, Audit, Manage Change, and ImproveHazard Management Practices and ProgramManaging chemical reactivity hazards so that uncontrolled chemical reac-tions are avoided is an ongoing endeavor, throughout the facility lifetime. A truly inherently safer process will reduceor eliminate the hazard Kletzrather than simply reducing itsimpact.
YES Batch chlorination; wasteneutralization2.
Deviations are abnormal situations, outside the bounds of intendeddesign and operation. In other cases, thelimits will need to be developed through combination of reactivity infor-mation discussed in Sections 4.
They have a responsibility to educate management in managements own terms and to give management the opportunity toparticipate in the development activities. It endorses sustained commitment of resources ablage all necessaryactivities, including material testing, as well as the timely completionand documentation of review, audit, and investigation action itemresolutions.
Risk con-trol strategies in the first two categories, inherent and passive, are consid-ered more reliable because they depend on the physical and chemicalproperties of the system rather than the successful operation of instru-ments, devices, procedures, and people.

The propylene dichloridewas purchased in railcar quantities and unloaded into a large storage tank,from which it was metered into 55 gal drums for sale to customers. Is any substance identified asspontaneously combustible? Designing emergency ventilation systems to capture fugitive emis-sions of toxic, corrosive, or malodorous gases or vapors.
The objective of managing change, in anlagd context of chemical reac-tivity hazards, is to ensure that all changes made to a facility after startupthat might introduce a new chemical reactivity hazard, increase the likelihood of an uncontrolled chemical reaction, make safeguards against uncontrolled chemical reactions less effec-tive, or make the consequences of an uncontrolled chemical reaction moresevereare identified, evaluated, anlagee addressed so that chemical reactivity inci-dent risks are adequately controlled.
These can 159 used for assessing risks of new facili-ties with no operating experience, as well as for estimating the anlaage ofrare events such anlahe vessel mechanical failures at operating conditions andfor fully quantitative risk studies. It recognizes the importance of managing chemical reactivity haz-ards to avoid serious incidents. Engineering and administrative requirements for safe storage,including the full range of consequences should requirements not bemet or procedures not followed Responses to process upsets, including releases Emergency response guidelines.
In somestates, legislation now requires owners of chemical plants to maintain up-to-date documents and procedures on many aspects of plant design andoperation. If so, then activitiesdescribed in Sections 4. Measures proposed see Figure 4: Hugo TU Berlin Dr.
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.
