Fines of $250 to $500 can be issued for violating the fireworks curfew, using fireworks within city parks, hazardous use of fireworks, and using illegal fireworks.The fireworks shows keep you entertained and grilled food keeps you satisfied, but who is keeping you safe on what is often dubbed the most dangerous holiday?Clark Regional Emergency Services Agency will add two to three extra people to field 911 calls from 7 p.m. Wednesday until 5 a.m. Thursday.Katy Myers, operations manager for CRESA, said the agency discourages people from calling to report noise complaints unless they suspect hazardous or illegal fireworks use or that fireworks are being discharged past curfew. On the Fourth of July, though, 911 is prepared for anything, and how busy the phones are varies from year to year.“Every year is different,” Myers said. “It depends on the day of the week and the weather.”Camas-Washougal Fire Chief Nick Swinhart said a brush unit will be on patrol from 6 p.m. to midnight in Camas while an engine and brush crew will patrol Washougal after the Camas-Washougal Concert Series fireworks display. A deputy fire marshal will also be on patrol.“July 4 usually tends to be a busy time for us,” he said.Firefighters will keep an eye out for people using illegal fireworks or using legal ones in an unsafe manner, Swinhart said. Firefighters tend to see a few grass, brush or roof fires and the occasional fireworks-related injury.
