*1 Before: McKEOWN, CHRISTEN, and BRESS, Circuit Judges.

Arizona state prisoner Douglas Wayne Derello appeals pro se from the district court’s summary judgment for failure to exha ust administrative remedies in his 42 U.S.C. § 1983 action alleging deliberate indifference to his safety. We have *2 jurisdiction under 28 U.S.C. § 1291. We review de novo. Williams v. Paramo , 775 F.3d 1182, 1191 (9th Cir. 2015). We affirm.

The district court properly granted summary judgment because Derello failed to exhaust administrative remedies and he failed to raise a genuine dispute of material fact as to whether administrative remedies were effectively unavailable to him. See Ross v. Blake , 578 U.S. 642-45 (2016) (setting forth circumstances when administrative remedies are effectively unavailable); Woodford v. Ngo , 548 U.S. 81, 90 (2006) (proper exhaustion requires “using all steps that the agency holds out, and doing so properly (so that the agency addresses the issues on the merits)” (internal quotation marks omitted)).

We do not consider matters not specifically and distinctly raised and argued in the opening brief. See Padgett v. Wright , 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
