Utah Temporary Mass Gatherings Sanitation — Utah Admin. Code R392-400 (Emergency Medical Care Requirements at R392-400-11)[1]
Summary
Utah has no mass-gathering chapter in its code but does have a dedicated statewide rule administered through local health officers, and despite its "Sanitation" title R392-400 is not sanitation-only. A temporary mass gathering is an anticipated assembly "of 1000 or more people, which continues or can reasonably be expected to continue for two or more hours per day," at a site used for a purpose different from its designed use and usual occupancy. R392-400-11 requires at least one first aid station, with emergency medical care and necessary supplies and equipment "provided as determined by the emergency medical provider and the emergency medical operations plan," and the health officer or emergency medical provider may require more than one station. The operator must give the emergency medical provider a site map showing stations, emergency vehicle ingress and egress, landing zones and rendezvous locations, keep accurate patient and treatment records, and notify the health officer of serious injury or communicable disease. The health officer or provider may require dedicated stand-by ambulances or additional EMS personnel.
So what
Utah is performance-based rather than ratio-based, which makes the emergency medical operations plan the controlling document — whatever it says about staffing is what the rule enforces, so write it deliberately and negotiate it early with the local health department and the licensed EMS provider. The local health officer holds real backstop power to demand more stations, more EMS personnel or dedicated stand-by ambulances, so leave headroom in the contract. Permit filings are due 30 days before the gathering and 15 days before first advertising, and a single-day show of 1,000 people lasting two hours already trips the rule.
