Dust collection is the primary engineering control for wood and MDF dust in scene shops. This article covers how dust collectors work, the difference between bag-filter and HEPA systems, combustible dust explosion hazard, NFPA 652 and 664 requirements, ductwork transport velocity, and maintenance requirements.
Airborne particulate from wood, MDF, foam carving, textiles, welding, and spray painting is a pervasive chronic hazard in performing arts production. This article covers particle size and respiratory deposition, wood dust carcinogenicity, MDF and formaldehyde, polyurethane isocyanate sensitization, welding fume, OSHA PELs, ACGIH TLVs, and respirator selection.
