11.1 Safety Precautions for MSA Self-Contained Breathing Apparatus Cylinders
The operating manual of the cylinders has to be regarded.
WARNING!
This system must be supplied with respirable or higher quality air according to EN 12021.
DO NOT drop the cylinder or bump the valve knob. An unsecured cylinder can become an
airborne projectile under its own pressure if the valve is opened even slightly.
Never carry or move a cylinder by the handwheel. If a cylinder is removed from a horizontal
shelf by grasping the handwheel, the weight of the cylinder can cause the cylinder to rotate
downward causing the valve to open slightly.
Avoid dropping the cylinder or bumping the handwheel.
Use the handwheel only to open and close the cylinder valve.
A valve could partially open causing the cylinder to become an airborne projectile under its own
pressure and result in serious personal injury or death.
Remove from service if cylinder shows evidence of exposure to high heat or flame: e.g., paint
turned to a brown or black color, decals charred or missing, gauge lens melted, or elastomeric
materials distorted.
Use this device only after receiving proper training in its use. Use in accordance with this label
and MSA apparatus instructions.
Do not use unless the cylinder is filled to the maximum working pressure.
Do not alter, modify, or substitute any components without approval of the manufacturer.
Inspect frequently. Maintain according to manufacturer's instructions. Repair only by properly
trained personnel.
The instructions for use of the cylinder and valve assembly have to be regarded.
Misuse can result in serious injury or death.
Breathing apparatus cylinders should be fully recharged as soon as possible after use.
Cylinders should not be stored partially charged:
If used partially charged, the duration of the SCBA is reduced.
For maximum safety, the cylinders should be stored full or at a pressure above ambient but less
than 7 bar.
Prior to recharging, cylinders must be examined externally for evidence of high heat exposure,
corrosion, or other evidence of significant damage.
If there is any doubt about the suitability of the cylinder for recharge, it should be returned to a
certified hydrostatic test facility for expert examination and testing.
Always check to be sure the retest date is within the prescribed period and that the cylinder is
properly labeled to indicate its gaseous service. New labels are restricted items which are not
available except through certified hydrostatic test facilities.
When replacing cylinder valves or after the retesting of cylinders, make sure the proper cylinder
valve, burst disc, and O-ring are installed prior to cylinder recharging. Determine the maximum
service pressure of the cylinder. All cylinders shall be filled to the designated service pressure
only.
