Grenade attacks have gradually become one of the most used surprise acts of terrorism as well as civil unrest. And even if these attacks are often unanticipated, the risks can be mitigated.
The explosion of a grenade takes a predictable upside-down cone shape. It can generate a blast with a six-meter kill radius. It is possible for a bystander to outrun the explosion seconds between impact and detonation. However, an upright posture will leave the bystander vulnerable to shrapnel.
So, what should you do if there’s a grenade explosion? First off, your reflexes should be quick.
During a grenade explosion, scan the area for possible cover immediately. If cover isn’t available within three steps, take one giant leap away from the grenade and to the ground. The aim here is to move out of the cone-shaped explosion and away from the path of shrapnel, which rarely travels along the ground.
Your feet should be positioned toward the blast in order to protect your brain. Cross your legs in order to protect femoral arteries. Covering your ears would prevent tympanic membranes from rupturing. Keep your elbows tight against your rib cage and open your mouth to regularize internal and external pressure and prevent the lungs from bursting.
Take note that in an urban environment, the danger of the blast will be compounded by the landscape—cement buildings and glass windows joining a litany of potential hazards. The explosion will create a secondary set of lethal projectiles from these surroundings. Always be on your guard.
