notified chemical will be reviewed with relevant employees before the notified chemical is stored in the warehouse. The MSDS shall be readily available to employees. Formulating Site Formulation of Cleaners and Paint Strippers This section assumes that the 10% of the imported notified chemical, eventually imported as commercial grade product, will be formulated into industrial cleaners and/or paint stripper products. The formulation process is usually a batch process in a closed vessel operating at atmospheric pressure. The notified chemical is added using a powered drum pump, a hand operated hand pump or decanted into a container and added manually at the appropriate stage of the formulation procedure and mixed by mechanical agitation. There is a potential during these types of operation for skin contact when handling the drum pump or decanting into a container. In addition there is the possibility of eye contact if the notified chemical drips from the drum pump during handling. After the addition of other ingredients, and further mixing a sample of the formulated product is taken for testing. The final product is transferred to storage tanks for later packaging into containers of varying capacity for industrial and commercial markets. Cleaning and maintenance of equipment would occur thereafter. Assuming a batch size of 2000 L, the notifier estimates time of potential exposure as: Transfer of liquid from drums to storage: 20 minutes per drum when handling the air pump. Sampling by process operator: 5 minutes per Number of personnel involved per batch: Transfer of liquid from drums to feed storage Sampling: 1 Number of batches per year: 1st year: 0 1st year: 20 Estimated total potential exposure times, During transfer operations (years 2 to 5): = 1 operator x 0.3 (hour) x 20 = approximately 6 hours per year at peak production. Sampling (years 2 to 5) = 1 operator x 1/12 (hour) x 20 = 1.6 hours per year at peak production. Thus potential exposure would be approximately 8 hours per year in years 2 to 5 for an operator i.e. less than 1% of annual work hours. Most likely exposure during production of a formulated product is skin contact. Potential exposure when packaging product
