Blast

Attacks from this weapon explode on impact, hurling debris and shrapnel in all directions.
When working out a hit from a Blast weapon, anyone within the weapon’s blast radius in metres, indicated by the number in parentheses (X), is also suffers a single hit from the weapon. Roll damage once and apply it to each character affected by the blast. A Blast weapon also scatters when the user fails his Ballistic Skill test when firing it (see page 230).
