About 3,243 acres have burned and the wildfire on the slopes of Mount Diablo is 60 percent contained after the fire was first reported around 1:10 p.m. Sunday near Morgan Territory Road, southeast of Clayton.
Two firefighters suffered minor injuries as of Monday and a third minor injury was reported today.
The third firefighter was an inmate from the California Department of Corrections and Rehabilitation and was airlifted after he suffered heat exhaustion, CDCR officials said.
The Bay Area Air Quality Management District issued a smoke advisory because of the fire on Monday, which remained in effect today.
An air district spokesman said the advisory would be canceled once the fire was fully contained.
Mandatory evacuations for residents in the area were lifted this afternoon and most roads have reopened, according to Cal Fire.
More than a dozen agencies are involved in the fire response.
No homes have burned, but a Cal Fire official said that a communication shed that contains electrical equipment was destroyed Sunday night.
Several schools and city agencies in the area canceled outdoor activities, but today Danville city officials said all sporting leagues and other scheduled events would resume outside.
With lower temperatures and less smoke from the fire, activities were able to resume.
However, city officials advised residents to stay hydrated and aware of smoky conditions that may affect air quality, especially the young, elderly and those with respiratory issues.
