Handling requirements

Magnesium hydroxide is supplied either as aqueous slurry or as a dry powder. The slurry is required to be stored in agitated storage tanks to prevent settling of solids. Since the product freezes at 32°F, there is no need for specialized heat tracing, unless it is used in very cold climates.

Improved feedstock pretreatment is important to minimize catalyst consumption and reduce subsequent spent-catalyst handling requirements. Selective hydrogenation of dienes can be used to reduce acid consumption, both in HF and H2SO4 alkylation (29). More effective adsorptive treating systems have been appHed to remove oxygen-containing contaminants that are frequently introduced in upstream processing steps. 

Storage and Transportation. Handling requirements are similar to Hquefied petroleum gas (LPG). Storage conditions are much milder. Butylenes are stored as Hquids at temperatures ranging from 0 to 40°C and at pressures from 100 to 400 kPa (1—4 atm). These conditions are much lower than those required for LPG. Their transportation is also similar to LPG they are shipped in tank cars, transported in pipelines, or barged. 

Butylenes are not toxic. The effect of long-term exposure is not known, hence, they should be handled with care. Reference 96 Hsts air and water pollution factors and biological effects. They are volatile and asphyxiants. Care should be taken to avoid spills because they are extremely flammable. Physical handling requires adequate ventilation to prevent high concentrations of butylenes in the air. Explosive limits in air are 1.6 to 9.7% of butylenes. Their flash points range from —80 to —73° C. Their autoignition is around 324 to 465°C (Table 2). Water and carbon dioxide extinguishers can be used in case of fire. 

Gelation of egg yolk occurs below 6 C. When frozen egg yolk is thawed, it has a gel-like consistency and is difficult to handle, requiring special equipment water is sometimes added in order to thin the thawed frozen yolk. Frozen yolk products have ingredients such as sugar or salt added to reduce gelation and improve ease of handling. 

Specialized training or technical literature by raw material suppliers to address special use or handling requirements. 

The process of building a list of candidates begins with the client. By examining the specific synthesis desired or material processing and handling required, you can search for tollers that possess the skills and equipment to meet the processing scope.

Handling and packaging needs for batteries are different. Batteries need to be handled and packed to prevent short-circuits and minimize transportation costs. Again, a commercial company can provide appropriate packaging materials and instructions designed to minimize handling requirements and costs and eliminate possible liabilities associated with mispackaged materials. 

Some GLP professionals consider positive control substances (i.e., those materials intended to validate responsiveness of the test system to a chemical or biological challenge) to also be reference substances, as opposed to control substances however, the point is somewhat moot as the FIFRA GLP Standards characterization and handling requirements are exactly the same for both control and reference substances. As with test and control substances, reference substances must be characterized (usually determination of purity and stability) according to the abbreviated GLP Standards (see next section).
