We do put them inside a subdir of /tmp, but you could probably do something similar that puts them into /scratch.

That way any job a user runs cannot possible access this file system. Essentially we define $TMPDIR as /scratch, which Slurm cleans up in epilogue scripts, but some users still keep writing to /tmp instead which we do not want. We would use tmpwatch to clean up /tmp but I would rather just prevent people from writing to it within Slurm.
