Theatrical scenic painting involves water-based and solvent-based media, spray techniques, paint frames, and floor work on drops -- each with specific hazards. This article covers paint chemical hazards, spray booth requirements, flammable finish safety, paint frame and ladder protocols, and OSHA Hazard Communication requirements.
Welding introduces arc radiation, metal fume, fire, and burn hazards not present in woodworking. This article covers MIG, TIG, and stick welding, OSHA 29 CFR 1910 Subpart Q requirements, manganese and hexavalent chromium fume hazards, LEV ventilation, welding PPE, arc flash protection for non-welders, and fire watch requirements.
PPE is the last line of defense against performing arts hazards. This article covers the OSHA PPE hazard assessment requirement, eye and face protection categories, hearing protection and the 85 dB(A) action level, respirator types and selection, hand protection and the no-gloves-near-rotating-machinery rule, and PPE program management.
Performing arts programs use dozens of chemicals with cumulative health effects. This article covers OSHA HazCom requirements, how to read an SDS, common solvents and adhesives, theatrical fog fluid hazards, dry ice CO2 asphyxiation risk, chemical segregation, and emergency response procedures.
Labels are the first line of hazard communication in a performing arts facility. This article covers the six required GHS label elements, the nine GHS pictograms, secondary container labeling requirements, rigging hardware WLL markings, electrical panel labeling, and pipe identification standards.
Flammable liquids are present throughout the performing arts facility. This article covers NFPA 30 liquid classification (Class I, II, III), flash points, approved containers and storage cabinets, quantity limits, dispensing hazards, bonding and grounding, spontaneous combustion from oily rags, and aerosol can safety.
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.
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.
Ventilation is the most powerful and most overlooked engineering control in performing arts production. This article covers the difference between dilution and local exhaust ventilation (LEV), capture velocity requirements, ventilation needs by work area (scene shop, paint shop, costume shop, welding), makeup air requirements, and methods for verifying ventilation performance.
Orchestra pits, sub-stage crawl spaces, and attic catwalks can all qualify as permit-required confined spaces under OSHA 29 CFR 1910.146. This article covers the confined space classification process, pre-entry atmospheric testing, the entrant/attendant/supervisor role structure, entry permits, non-entry rescue, and indoor air quality concerns including CO, theatrical haze, and dry ice CO2 accumulation.
