inputs from the range of individu- als in a foundry operation cited in the previous step. In searching for promising improvement methods, the experiences of other foundries or of other related industries should be sought, as well. A best practices approach strives to


control those factors which have the greatest potential to cause exposures. All of the exposure control categories should be thoroughly explored to identify the most effective options. Tis important point is sometimes overlooked, and a measure such as ventilation may be singled out as the preferred improvement option when operational or work practice changes, in combination with ventila- tion improvements, may prove more effective. Only potentially sustainable exposure control methods should be considered (see Step 4). Care should be taken in the


selection process to assure candidate improvement options are feasible for the metalcasting facility’s set of circumstances and that it addresses the following constant needs: • The candidate exposure control improvement option must not have any significant safety and health risks which attend its use


• The ability of the foundry to produce quality products in a timely manner must not be impaired with use of the proposed exposure control


• Workers accept the exposure con- trol method to the extent that they acknowledge the need for it and agree to cooperate in assuring the method is employed correctly.


Step 4. Assure Sustainability of Exposure Controls


Sustainability addresses the need


for the exposure controls, with a reasonable amount of maintenance, to consistently provide protection against exposure over time. The possible need for personal protec- tion as a supplement to application of exposure controls hinges strongly on the confidence level evidenced by the sampling data gathered during consistent application of the control measures.

Developing consistency in worker


protection has several needs which are well-documented in the field of industrial hygiene: 1. Management commitment 2. Resources 3. Defined operational and mainte-


nance procedures 4. Training


5. Periodic evaluation and follow-up. Te tables present an action plan to


achieve each of these four key steps of a best practices approach.
