Incompatible substances

In any warehousing operation, it is essential that incompatible substances be isolated to avoid a reaction in case of a spill or fire. Where highly... 

Safety aspects are considered in two phases (Fig. 11). In the rule based synthesis some safety related rules are applied in process concept selections. These include rules such as separate corrosive or hazardous components first or avoid using chemically incompatible substances in the same process. ... 

The term can refer to any undesired results occurring when substances are combined. In the context of this publication, it refers to incompatible substances giving an undesired chemical reaction when combined, posing a chemical reactivity hazard under a defined scenario. 

Concise guidance targeted at companies engaged primarily in the bulk storage, handling, and use of chemicals to prevent inadvertent mixing of incompatible substances. 

The formation of micelles in a solvent that is selective for one of the blocks is one of the most important and useful properties of block copolymers. For example, micelles formed by block copolymers can solubilize otherwise insoluble substances, they can be used to microscopically mix incompatible substances and they can stabilize colloidal particles or form microemulsions. 

Facilities should examine process and storage areas and equipment to ensure that potentially incompatible substances are adequately separated. The design should be such that leaks or spills of highly reactive or incompatible chemicals are not collected within the same containment. 

Provision of adequate space, widi physical separation and containment for incompatible substances, each area to be marked with the permitted contents, the hazards and the necessary precautions, and incorporating an area for the storage of enpty containers ... 

Dimethyl phthalate is sensitive to prolonged exposure to light and it should therefore be stored in a cool, dark, dry, well-ventilated area that is protected from physical damage, and isolated from incompatible substances. Containers of dimethyl phthalate may be hazardous when empty as they may retain product residues such as vapors and liquids. There is a slight fire hazard when exposed to heat, and above the flash point (see Section 10) explosive vapor-air mixtures may be formed. Carbon dioxide and carbon monoxide are released when dimethyl phthalate is heated to decomposition. Solutions of dimethyl phthalate in acetone, dimethyl sulfoxide, ethanol... 

If Cl, F and H2O were to behave as perfectly incompatible substances and therefore increase in concentration in the melt, then the ratio of Cl, F and OH in successive aliquots of apatite will be constant as crystallization progresses (Candela 1986), if the effect of temperature is neglected. 

Considering the effect of temperature, again with Cl, F and with H2O behaving as perfectly incompatible substances in the melt, variations in Cl F OH in apatite reflect nothing other than how equilibrium constants change with temperature (Piccoli and Candela 1994). 

STORAGE Keep in a tightly closed container keep in a cool, dry, well ventilated area away from incompatible substances store only if stabilized. 

DISPOSAL AND STORAGE METHODS product residues and sorbent media may be packaged appropriately and placed in a sanitary landfill atomize large amounts by high temperature incineration with scrubbing equipment use deep-well injection for disposal store in tightly closed containers storage should be in a cool, dry, well-ventilated area away from incompatible substances.. 

DISPOSAL AND STORAGE METHODS absorb in sand or other inert absorbent, and place in sealed containers in a secured, sanitary landfill atomize in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device keep in tightly closed containers protect against physical damage isolate from incompatible substances and from any source of heat or ignition. 

DISPOSAL AND STORAGE METHODS manage whatever cannot be saved for recovery or recycling in an approved waste disposal facility dispose of container and unused contents in accordance with federal, state and local requirements store in a cool, dry, well-ventilated area keep in tightly closed containers and protect against physical damage separate from incompatible substances avoid heat, flames, and ignition sources. 

DISPOSAL AND STORAGE METHODS may be disposed of by dissolving in appropriate solvent and atomizing in a suitable combustion chamber store in a cool, dry location use only with adequate ventilation keep in a tightly closed container protect against physical damage store separately from reactive or combustible materials isolate from incompatible substances and keep out of direct sunlight.
