Follow spots present electrical, UV radiation, lamp explosion, and carbon monoxide hazards that are frequently underestimated in educational theater. This article covers all follow spot light source types, HMI and xenon lamp pressure risks, UV protection, carbon arc ventilation, and operator training requirements.
A fallen loudspeaker is a potentially fatal event. This article covers design factors (7:1 minimum), safety cables, rigging hardware selection and inspection, structural attachment requirements, and the inspection program required for permanently flown speaker systems.
Rope is foundational to theatrical rigging and one of the most misunderstood materials in performing arts. This article covers rope construction, fiber types, working load limits, design factors, knot efficiency, visual and internal inspection, and the retirement criteria that keep crews safe.
Not all chain is safe for overhead rigging. This article covers chain grades (80, 100, proof coil), why unmarked chain is retired, entertainment-rated vs. industrial hoists, load chain inspection and retirement criteria, sling angles, and the documentation program for chain in theatrical facilities.
Electric chain hoists and motorized winch systems require strict adherence to ANSI E1.6-1 and ASME HST-4. This article covers entertainment vs. industrial hoists, WLL calculations, dual limit switches, E-stop requirements, performer flying (ANSI E1.43), and the annual inspection and load-test program.
Movable stage platforms create crush, pinch, and collision hazards that static scenery does not. This article covers turntable and wagon design requirements, machine guarding, sensing edges, E-stop systems, pre-show checks, performer protection during automation, and lockout/tagout for maintenance.
The costume shop is one of the most hazardous spaces in a performing arts facility. This article covers sewing machine and cutting hazards, steam burns, chemical dyes and adhesives, spray treatments, flame treatment requirements under NFPA 701, costume storage fire safety, and ergonomics.
Dressing rooms are frequently overlooked as hazardous spaces. This article covers electrical safety and GFCI requirements, theatrical makeup chemical hazards, prosthetic adhesives, aerosol products, infection control for shared makeup and costumes, and the conduct and privacy policies required in educational programs.
Storage areas in performing arts facilities concentrate fire risk, fall hazards, and chemical exposures. This article covers OSHA housekeeping requirements, aisle and egress clearance, shelf load ratings, scenery storage, chemical segregation and NFPA 30 flammable liquid limits, and rigging hardware storage.
Theatrical electrical systems are governed by NFPA 70 (NEC) Article 520, OSHA 29 CFR 1910 Subpart S, and multiple additional NFPA standards. This article explains the electrical code framework, theater-specific NEC requirements, UL listing, the role of the Authority Having Jurisdiction, and when licensed electrician work is required.
