Respirable dust, including potential crystalline silica, encountered during asphalt-mix production and road-paving operations.

Airborne form

dust

The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.

Description · 1
Management from an asphalt mix production and paving company requested a health hazard evaluation concerning employee exposure to respirable dust and respirable crystalline silica during asphalt mix production and road paving activities.

The NIOSH evaluation reports that personal exposures to respirable dust and respirable crystalline silica were below the occupational limits it used, while recommending controls such as enclosed, filtered cabs and water during sweeping.
