9.5 Manual Isolation Valve
Gas cylinders charged to pressures of greater than 50psi must incorporate a manual isolation valve that can
be operated from outside of the robot.
9.6 Remote Isolation Valve
Where the manual isolation valve is not integral to the gas cylinder (for example: the gas is normally
released as soon as the cylinder is screwed into it’s mating pneumatic connection) must have an additional
remote isolation valve accessible from outside of the robot.
9.6.1 Position
Any remote isolation valve shall be positioned to minimize the pipe length between it and the cylinder.
This pipe length must fully vent before the cylinder is fully unscrewed from the pneumatic connection.

it only states manual release ie, not automatic but does not mention the use of tools
