Handling and storage

Does an inventory exist for all materials (raw materials, products, byproducts, and waste materials) stored onsite Provide a schedule of materials stored onsite. Identify the risk category. 

Have all legal requirements associated with storage and handling of materials been identified Provide schedules of applicable legal requirements. Provide details on how the regulations are enforced. Identify the risk category. 

Are raw process and waste materials stored in a safe and appropriate manner for example, are bulk acids in tanks bunded with secondary containment, are flammable materials in a fire-protected, ventilated store, are powders and pellets in areas fitted with dust extraction segregation of noncompatible materials Provide details of existing storage arrangements, inducing plans and specifications. Identify risk areas. Identify the risk category. 

Has consideration been given to the requirements for segregation of incompatible materials Provide details on the type of wastes stored in specific areas. Identify risk areas. Identify the risk category. 

Are all stored materials labeled clearly and correctly Identify a schedule of omissions. Identify the risk category. 

Carbon black should be stored in a clean, dry, uncontaminated area away from exposure to high temperatures, open flame sources and strong oxidizers. Since carbon black will adsorb moisture and chemical vapors, it should be stored in closed containers. 

All liquid materials must be in secure vessels, which must be bunded to contain any spillage or leakage from the primary storage vessel. With certain of the materials -formaldehyde, ammonia and the various solvents - additional local exhaust ventilation is required to restrict the possibility of exceeding the imposed safe exposure levels for the 

Poor housekeeping practices can allow materials, containers, debris, or unused equipment items to be stored, placed, or handled so that they impair fire protection systems. Examples of such inappropriate storage and handling are  

Although it might be tempting to use the free space in switchgear, boiler, compressor, and other equipment rooms for the storage of brooms, paint, drawings and manuals, spare parts, and various other utility and maintenance supplies, it is essential to resist such practices. Suitable broom closets, spare parts storerooms, and utility rooms should be constructed for such storage. 

Small quantities [1 gal (4 I) or less] of flammable or combustible paints, solvents, or cleaning materials, including aerosol cans, should be stored in approved flammable liquid storage cabinets. Large quantities [more than 1 gal (4 I)] of these materials should be stored in separate, remote, or fire-rated 

The cardinal rule for proper disposal of any organic solvent also applies to the carboxylic acids. Do not dump any solvent into any sewers, on the ground, or into any body of water. 

Any unused or uncontaminated solvent can be sent to a licensed reclaimer or to an approved incinerator. Any contaminated solvent may have to be analyzed by a method recommended by the solvent manufacturer prior to recycling in a licensed facility. The solvent producer should be able to answer any questions on recycling or disposal practices. Any disposal process must follow all local, state, and federal regulations 

The monohydric alcohols have densities and surface tensions similar to many aliphatic ketone solvents. The alcoholic solvents afford a wide range of evaporation rates and excellent solvency for various resins and polymeric compositions. The four lowest molecular weight alcohols are completely miscible with water and with most other organic solvents. Tertiary butyl alcohol, diacetone alcohol, furfuryl alcohol, and tetrahydrofurfuryl alcohol are also completely soluble in water. Many of the alcohols form minimum boiling-point azeotropes with water. 

Texanol ester alcohol 2,2,4-trimethyl 1,3-pentanediol monoisobutyrate 25265-77-4 

The glycol ethers formed by reaction of an alcohol or phenol with ethylene or propylene oxide to yield a solvent with both an alcoholic and ether functional groups are discussed in Chapter 13. Major producers of the alcoholic solvents include BASF Corporation, Eastman Chemical Company, Exxon Chemical Company, Hoechst Celanese Company, Shell Chemical Company, and Union Carbide Corporation. This chapter will discuss the naming nomenclature for the alcohols, their physical properties, the various industrial uses, possible environmental concerns, and the safe handling of the alcohols.

The properties required by jet engines are linked to the combustion process particular to aviation engines. They must have an excellent cold behavior down to -50°C, a chemical composition which results in a low radiation flame that avoids carbon deposition on the walls, a low level of contaminants such as sediment, water and gums, in order to avoid problems during the airport storage and handling phase. 

Mild steel is a suitable material of constmction for storage and handling of DMAC at ambient temperatures. Aluminum or stainless steel is recommended for cases involving very stringent color or iron contamination requirements. Mild steel is not recommended for high temperature service or handling aqueous solutions of less than 50 mol % (82.86 wt %) DMAC. 

Shipment, Stora.ge, ndPrice. Butyrolactone is shipped in unlined steel tank cars and plain steel dmms. Plain steel, stainless steel, aluminum, and nickel are suitable for storage and handling mbber, phenoHcs, and epoxy resins are not suitable. Butyrolactone is hygroscopic and should be protected from moisture. Because of its low free2ing point (—44° C), no provision for heating storage vessels is needed.

Most A1F. and cryoHte producers have their own HF production faciUties. HF vapor is reacted with alumina trihydrate to form A1F. in a fluid-bed reactor. HF is reacted with sodium hydroxide to form sodium fluoride, which is then used to produce cryoHte. Producers who manufacture these products solely for use in the aluminum industry do not generally install Hquid HF storage and handling faciHties, and do not participate in the merchant HF market.
