I Get killed from my own blast??

So i was creating a projectile ball thing that shoots out of a tool. I tried to make it so whenever it touched anything it would explode. When i shoot it however, it kills me. I tried to add or multiply the position of the projectile from the tool but it still didnt work. Is there any way to make the me immune to the explosion itself? The script it long, so srry about that.

local Tool = script.Parent

Tool.RemoteEvent.OnServerEvent:Connect(function(Player, CoolDown)
    local Character = Player.Character
    local hum = Character.Humanoid
    CoolDown = true


local Blast = Instance.new("Part")
Blast.BrickColor = BrickColor.new("Really red")
Blast.Material = "Neon"
Blast.Transparency = 0.25
Blast.Anchored = false
Blast.CanCollide = false
Blast.Shape = Enum.PartType.Ball
Blast.Locked = true
Blast.Size = Vector3.new(3,3,3)
Blast.Position = Tool.Handle.Position
Blast.CFrame = Tool.Handle.CFrame
Blast.Parent = Character
local bv = Instance.new("BodyVelocity")
 bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
bv.Velocity = Character.HumanoidRootPart.CFrame.lookVector * 100
bv.Parent = Blast


    local damagefortheBlast = true
Blast.Touched:Connect(function(hit)
    if not damagefortheBlast then return end
    damagefortheBlast = false
    local ehum = hit.Parent:FindFirstChild("Humanoid") or   hit.Parent.Parent:FindFirstChild("Humanoid")
 if ehum and ehum ~= hum then
    ehum:TakeDamage(10)

end
wait()
damagefortheBlast = true

for i = 1,10 do
    local Explosion = Instance.new("Explosion", game.Workspace)
    Explosion.BlastPressure = 5000
    Explosion.BlastRadius = 4
    Explosion.ExplosionType = Enum.ExplosionType.CratersAndDebris
    Explosion.DestroyJointRadiusPercent = 1
    Explosion.Position = Blast.Position
    Explosion.Parent = workspace
    Explosion.Visible = true

local damagefortheExplosion = true
Explosion.Hit:Connect(function(hit)
    if not damagefortheExplosion then return end
    damagefortheExplosion= false
    local ehum = hit.Parent:FindFirstChild("Humanoid") or   hit.Parent.Parent:FindFirstChild("Humanoid")
     if ehum and ehum ~= hum then
    ehum:TakeDamage(10)

end
wait()
damagefortheExplosion = false

end)







    end
        end)
            end)
