Section 25-15. Requirements of compressed air cylinders before filling

Before cylinders are filled, they shall be checked to verify that the deadline for testing has not expired, that the inspection stamp is valid and that the valve is undamaged.

If the test deadline has expired or the cylinder does not have a valid inspection stamp, it must not be filled until it has been checked and tested.

If a cylinder or valve is damaged, or if damage is suspected, the cylinder shall not be filled until it has been checked by an approved inspector to the extent deemed necessary by the competent person.

Cylinders shall be filled so that the internal overpressure at 15 °C does not exceed the filling pressure stamped on the cylinder.
