Each 3M plant that and is supported by produces fluorochemical carboxylates a corporate industrial hygiene group. has an industrial hygienist on staff 3M's industrial hygiene program focuses on task-based exposure assessment and control. Exposures are identified and assessed qualitatively and/or quantitatively. Qualitative assessments are performed by an industrial hygienist. Quantitative assessments include task-based personal sampling for certain, specific fluorochemicals and/or source or area sampling. The results of the assessments support decisions on exposure control. Engineering controls are preferred, but personal protective equipment may be used on an interim basis or when effective engineering control is not feasible. 4. 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. Positionable local exhaust ventilation hoods are situated at significant point sources such as at drumbangs `when drumming. General room air provides for dilution ofairborne materials. S.
