Is a prison officer deliberately indifferent to health and safety concerns of an inmate?

CODE REGS., tit. 15 3290(d) between August 3, 2014 and May 22, 2015. Id. at 4; see also Farmer, 511 U.S. at 837 (official is deliberately indifferent when he subjectively knows of and disregards "an excessive risk to" the inmate's health or safety, or the official is "aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he . . . [draws that] inference."); Jeffers v. Gomez, 267 F.3d 895, 913 (9th Cir. 2001) ("A prison official is deliberately indifferent to a substantial risk of serious harm to inmates if that official is subjectively aware of the risk and does nothing to prevent the resulting harm.").
