Usually, there are strict safety protocols when there are guns on a set.
“On the film I recently made, even my plastic gun, I had to sign out, sign in every day,” Rhys Muldoon told BBC News. “So that’s why this particular case is so incredibly baffling.”
“There’s basic safety measures on every set,” Mike Tristano, an armorer in the film industry, told the BBC. “You never point a gun, even if it is not a firing gun, at anyone else. I’m at a loss how this could have happened and how it could have done that much damage.”
“Prop weapons do have a dangerous factor to them, even though they’re a lot safer than using a live firearm on set,” prop master Joseph Fisher told CNN.
Normally, when a gun has to be fired on a set, blanks are used.
BBC News said blanks are modified real rounds, but instead of having a metal bullet in the casing, normally they have either cotton or paper in its place. The end, where the bullet would be, is crimped to hold the powder in the casing, The Wrap reported.
“Typical prop load will be about 25 to 50% of the gunpowder in an actually projectile load that would be used in a regular weapon,” Fisher told CNN.
The Wrap reported that any gun used in production is considered a prop gun.
A prop gun can be a plastic one like Muldoon referenced that doesn’t fire, or a cap gun. Normally, according to the BBC, they are real weapons that have been modified to use blanks.
The modified weapon will give a bang, recoil and flash of light from the muzzle, leading to the authenticity of a production.
The wadding that holds the gunpowder in the cartridge can also be expelled, The Wrap reported.
Sometimes, productions will add extra powder to get more of a blast, BBC News reported.
“We do safety distances. We try to keep the actors slightly misaligned with the weapon, so that if the person firing the weapon is firing straight this way, the other actor in the frame is just slightly off,” Fisher said.
