Dispensing of dry powder in machining operations with vigorous mechanical motion or agitation
Dispensing the dry powder in a machining operation with vigorous motion, could result in aerosolization of the nanoparticles that could remain suspended in air after the operation is completed.
Note: Additional PPE and or EHS controls may be required based on the dry powder nanomaterial properties
Alternatively, Control Banding may be employed when more is known about material reactivity, exposure duration and material state.
