Floyd runs a small foundry.  He has determined that the amount of airborne crystalline silica at his shop exceeds the OSHA permissible limit.  He is now trying to decide the best way to protect his workers.  Floyd is not sure which type of control would be the best to implement for the long run.  This foundry uses a specialized sand casting method to manufacturer critical parts.

What should Floyd do?


















Train workers in better practices

Though Floyd will want to implement better work practices, this is not the best solution because it relies on employees conforming to the work practices and not making any unauthorized changes to them. Try Again

































Protective Equipment

This is probably the best immediate means to provide protection of Floyd's workers, but it is not the best long-term solution for Floyd because of the costs involved in setting up and maintaining a respiratory protection program, and the possibility that workers may not follow the program completely. Try Again






























Engineering Control

Yes.  This is the best permanent solution for Floyd because it reduces the hazard at the source of the silica, reduces the reliance on programs which may not be followed, and is usually a low cost when compared to the life expectancy of the controls.

Back to Taking Action to Protecting Against Silica






























Silica Substitute

While this would be the best choice in many circumstances, due to the nature of the casting method and the need for consistency, this is not Floyd's best choice. Try Again
