Force a player out of a seat with a global script?

I'm attempting to make it so when certain requirements are met, the player will be forced out of the seat they are in (by forcing them to jump) but I haven't found a way to get their character with a global script. I don't want to use a local script, so PLEASE don't suggest the idea. I'll understand if i'm simply just told there is no way to get the player with a global script.

Important part of code:

power = workspace.Power

power.Changed:connect(function(newValue)
	script.Parent.Info.SurfaceGui.Power.Text = "Power: "..newValue.."%"
	if newValue <= 0 then
		if workspace.OfficeChair.CamSeat.Occupant ~= nil then
		local hum = workspace.OfficeChair.CamSeat.Occupant
		local par = workspace:WaitForChild(hum.Parent)
		par:FindFirstChildOfClass("Humanoid").Jump = true
		elseif workspace.OfficeChair.CamSeat.Occupant == nil then print("") end
		workspace.Usage.Value = 0
		workspace.ComputerEnabled.Value = false
		workspace.Door1.Value = false
		workspace.Door2.Value = false
		workspace.LightEnabled.Value = false
		workspace.ComputerToggle.ClickDetector.MaxActivationDistance = 0
		workspace.Door1Switch.DoorButton.ClickDetector.MaxActivationDistance = 0
		workspace.Door2Switch.DoorButton.ClickDetector.MaxActivationDistance = 0
		workspace.LightSwitch.LightButton.ClickDetector.MaxActivationDistance = 0
	end
end)

Well you already found the humanoid. To get the character, you can either get the humanoid's parent, or use the .Character property on player.

local humanoid = ...
local player = ...
local character = humanoid.Parent
-- or 
local character = player.Character

Hope this helps! :)
