The volatile waste products, such as perfluoromethane, have been vented to the atmosphere in the past, but plans are being implemented 10 capture and destroy these releases by thermal oxidation over the next few years. The tars have been landfilled in a hazardous waste landfill in the past, but are all currently being incinerated at an in-house or extemal hazardous waste incinerator. The byproducts, manyof which are incompletely fluorinated with hydrogen atoms still present, can be recycled back into the ECF processorare partially degraded in stabilization processes and discharged to controlled, in-house, wastewater treatment systems. The treatment sludge associated with the ECF process has been either landfilled or land-incorporated in the past, but all ofthis treatment sludge is being landfilled off-site since early 1998. POSE is itselaf commercially viable product, but is primarily an important intermediate in the synthesisofsubstances used in many other 3M fluorochemical products. The majority is used to `produce functionally derivatized fluorochemicals and high molecular weight polymeric products. Unique chemistries can be created by derivatizing POSF through the sulfonyl fluoride moietyofthe molecule using conventional hydrocarbon reactions. POSF is reacted with methyl or ethyl amine to produce either N-methyl or N-ethylperfluorooctanesulfonamide (MeFOSA or ECFOSA). Someofthe MeFOSA and EtFOSA is isolated to be used as intermediates to be reacted to form other materials `The majority of the MeFOSA and EtFOSA is not isolated and subsequently reacted with ethylene carbonate to form either N-methyl or N-ethylperfluorooctane sulfonamido ethanol.. These are the principal building blocksofthe 3M product lines. CAS Number 1691-992 3M Company 4 `The following block flow diagram describes the process discussed above.

Briefly describe the engineering controls used to minimize exposure to this chemical: Materials are transferred using closed piping (where possible) from reactor vessels to other containers.

Vacuum charging of materials from drums is a standard practice. Local exhaust ventilation hoods are situated at significant point sources such as at drum bungs when drumming.

Briefly list the personal protective equipment your workers regularly wear to prevent exposure of this chemical: `Specific personal protective equipment is indicated on written operating procedures used by process operators. Respiratory protection: Tasks with significant exposure potential (charging, drumming, some. `maintenance tasks) are performed using positive pressure, pressure demand full face supplied air respirators. Tasks with moderate exposure potential (short term sampling from taps or drums, and some maintenance tasks) are performed using full face air-purifying respirators with organic vapor cartridges and P100 prefilters. Hand protection: All tasks identified as having potential for hand contact require neoprene (Scorpio) or nitrile industrial gloves. Body protection: Exposuresignificanttasks use one or two-piece PVC suits. Aprons may be worn for some low exposure potential tasks such as sampling. Foot protection: Tasks identified as posing a significant foot exposure potential require chemical resistant boots. Current exposures are expected t0 be less than those measured in the recent past. Significant sources of exposure have been identified and eliminated. In 1998 an extensive area air sampling ofthe production areas was performed. Areas with higher levelsofairbome materials were investigatedfurtherto identify sources. These sources, which include the flaking equipment, are iin the processofbeing eliminated or reduced through replacement with better ventilated equipment. In addition, the ventilation system in the primary production building (3) is being upgraded. `The fluorochemical hazard communication program was improved upon in 1998. This has resulted in improved exposure avoidance behaviors among production employees and better use of personal protective equipment requirements. Additional hand wash facilities have been installed in primary process buildings. Food consumption and other hand-to-mouth activities are prohibited. There is no smoking in process buildings. Processemployeesare instructed to remove and leave their work boots and work coveralls at the plant. Work coveralls are professionally laundered. Non-production equipment surfaces such as floors, doorknobs and stair rails are cleaned frequently. CAS Number 1691-992 3M Company 19 VIL CHEMICAL END USES A.
