Perhaps, but 175m is the listed safe distance for the M72 on the range from a US source I found

Attachment 420
This is from the US LAW manual.

Backblast. Light antiarmor weapons have little or no recoil, because the propellant gasses escape to the rear of the weapon. This backblast can damage equipment or seriously injure personnel who are too close to the rear of the launcher. When operating temperatures fall below freezing (0NC or 32NF), all backblast areas and safety zones double.
(1) M72-series LAW. This is an open-chambered weapon, so it has no recoil. The launcher's total backblast area extends 40 meters (44 yards) to the rear (Figure A-1) and is divided into two zones. During training, both should be marked off limits:
(a) Danger zone. All personnel, equipment, and flammable material must be clear of this area.
(b) Caution zone. The weapon's backblast may throw loose objects to the rear. Therefore, personnel must also stay clear of this area.

I think it's fair to say from reading those sources it's likely to be more than the odd pebble in the 40m zone...
