Total containment facility

Environmentally safe destruction of obsolete chemical weapons must be performed In facilities which assure total containment of blast effects and toxic gas In the event of an accidental detonation. Functional process requirements and recommended structural design procedures for containment rooms to accomplish this purpose are presented. The requirements presented are consistent with Department of the Army and Department of Defense Explosive Safety Board requirements. 

There are two types of containment total containment, and vapor containment. Irrespective of which type of containment is provided, the containment structure or facility will be equipped with a means of entrapping or detoxifying the evaporated or aerosolized chemical agent by filters, scrubbers, incinerators, or other appropriate means. Total containment and vapor containment are described as follows ... 

The target alkene should contain one or more pronounced stereogenic centers that do not permit facile (total) ring inversion of the most stable conformer. 

N Tank Farm. The 166-N Tank Farm Is an earthen-bermed tank farm containing one aboveground 5,200,000-L (1,375,000-gal) No. 6 fuel oil tank and four aboveground 400,000-L (105,000-gal) diesel oil storage tanks. The earthen berm has a total containment capacity of 11,500,000 L (3,030,000 gal) (WHC 1989b). The tank farm Is located between the 116-N air stack and the 116-N-2 radioactive chemical waste treatment and storage facility. It has been In operation since 1963. 

In this classification the basic facility is used for work with the least hazardous agents and the total containment facility is used for the most hazardous agents. For recombinant DNA research, the biosafety levels of these facilities have been abbreviated as BLl, BL2, BL3, and BL4 (previously called PI to P4) these terms are also used to refer to the corresponding facilities for other kinds of biohazard research (see Section 11.4). Table 10.1 indicates the level of facility that is appropriate for work with cancer viruses, recombinant DNA, and human pathogens. 

In this chapter we will only discuss the physical design of the first three levels of facilities. We will not discuss the design of facilities intended for total containment, as this topic is... 

Insert the appropriate code (see below) that indicates the maximum quantity of the chemicai (e.g., in storage tanks, process vesseis, on-site shipping containers) at yourfaciiity at any time du ring the caiendar year, if the chemicai was present at several locations within your facility, use the maximum total amount present at the entire facility at any one time. 

Enter the total pounds of the toxic chemical contained In all wastes from the reporting facility (air emissions, water discharges, solid wastes and off-sIte transfers) generated during the reporting year. This quantity may be the sum of all the release amounts reported on Form R if there is no on-site treatment of the chemical. The quantity will often be greater than the total reported release amounts because it includes waste prior to treatment. 

Calculating the Maximum Quantity of Lead and Lead Compounds. To calculate the maximum amount of lead and lead compounds present at your facility at any one time, you must consider types of metallic load and M types of lead compounds present at your facility, Including stockpiled raw materials, lead and lead oxide present in process equipment, the metallic lead and lead peroxide contained in finished batteries stored on-site, and stockpiled lead scrap. Since the reporting form is being prepared for lead compounds, the maximum amount reported is the total of the inventories of these materials. The maximum amount of metallic lead (2,305,000 pounds), lead oxide (205,000 pounds), and lead peroxide (625,000 pounds) present at your facility is 3,135,000 pounds, which is between 1,000,000 and 9,999,999 pounds. You would therefore report range 06 on Part III, Section 4, of the reporting form. 

In general, tlicsc Section 313 reports appear to be of limited value in emergency pUnming. Over time, however, tlicy nuay contain infonnation tliat cati be used by local plaimcrs in developing a complete understanding of the total spectrum of ha7.ru-ds tliat a given facility may pose to tlie community. 

A total of eight separate leather facilities were surveyed for the presence of N-ni croso compounds and two of these were resurveyed, Four of the eight plants were found to have airborne NDMA at levels greater than 0.5 yg/m. Table IV summarizes the operations of each plant and the highest level of NDMA found at that plant. The use of.DMAS is associated with the presence of airborne NDMA. Even a facility which had recently discontinued the use of DMAS, and another which used DMAS on an experimental basis, contained airborne NDMA. 

Mineral Oil Hydraulic Fluids. The majority of the components of mineral oil and water-in-oil emulsion hydraulic fluids are not on the TRI. Some water-in-oil emulsion hydraulic fluids contain ethylene glycol (Houghton 1992 Quaker 1993), which is subject to reporting under the TRI. Nonetheless, since ethylene glycol is used in numerous other applications and represents < 10% of the total volume of water-in-oil emulsion hydraulic fluids, it is not anticipated that TRI information concerning releases of ethylene glycol will be indicative of water-in-oil emulsion hydraulic fluid use. It may be difficult to estimate the release of mineral oil or water-in-oil emulsion hydraulic fluids to water by identifying occurrences of mineral oil (the major constituent) in water at a particular facility since mineral oils also find use in numerous other products and applications, and concentrations of the components cannot always be uniquely associated with mineral oil hydraulic fluid release. 

Owners/operators of facilities that burn small quantities of hazardous waste with a heating value of 5000 Btu/lb are also exempt from Part 266, Subpart H.5 They must, however, comply with the quantity restrictions based on stack height and the surrounding terrain. Also, the hazardous waste firing rate may not exceed 1% of the total fuel requirements. These units are prohibited from burning any waste that contains or is derived from dioxin-bearing wastes. Small quantity burners are required... 

The first commercial Fischer-Tropsch facility was commissioned in 1935, and by the end of the Second World War a total of fourteen plants had been constructed. Of these, nine were in Germany, one in France, three in Japan, and one in China. Both German normal-pressure and medium-pressure processes (Table 18.1) were employed. The cobalt-based low-temperature Fischer-Tropsch (Co-LTFT) syncrude produced in these two processes differed slightly (Table 18.2), with the product from the medium-pressure process being heavier and less olefinic.11 In addition to the hydrocarbon product, the syncrude also contained oxygenates, mostly alcohols and carboxylic acids. 

Releases may also occur from the use of this chemical in smoke and pyrotechnic devices. Hexachloroethane content of the smoke devices is about 44.5-46% of the total solid material. The smoke device bums, producing smoke which is mainly zinc chloride, but contains some hexachloroethane. It was estimated that about 0.3-5% of the mass of the reagents in the device is released to air as hexachloroethane in the smoke, assuming a 70% bum efficiency (Katz et al. 1980 Novak et al. 1987). On this basis, it was estimated that during 1982-1984, a maximum of about 6,683 kg (14,700 pounds) of hexachloroethane was released to the atmosphere at Fort Irwin, California, a major military training facility (Novak et al. 1987). Hexachloroethane in smoke (aerosol) was measured in a wind tunnel at concentrations ranging from 0.64-1.26 mg/m3 (average 0.89 mg/m3) (Cataldo et al. 1989).
