a gas, remember that many gases cannot support life. Therefore, as the ratio of released gas to oxygen
increases, so does the potential for suffocation.
• Wear appropriate safety devices to protect your hearing. Escaping air or gas can create a noise level that
can damage your hearing.
• Ensure that all pressurized air or gas is bled out of a pneumatic or gas-charged device before you start
to disassemble it. A thorough understanding of the assembly and its pressurized areas is necessary before
you undertake any maintenance. Refer to the appropriate product information for the correct bleeding
procedure.
It may not be obvious or intuitive which bolts or fittings are used to restrain a pressurized area. On some
assemblies, you must remove a cover plate to gain access to the structural bolts. Sometimes, to protect
you from a rapid release of trapped gases, a small port is exposed when you remove this cover plate.
Exposing this port ensures that the gas precharge is fully bled before disassembly. However, this is not
the recommended procedure for bleeding a pneumatic or gas-charged device, because it can expose you
to the dangers of escaping compressed gas and particulates that are expelled from the chamber or around
the seals. Do not assume that cover plates and ports are installed in all the critical locations.
Consult MTS when in doubt about the safety or reliability of any system-related procedure or modification
that involves devices that contain any type of compressed gas.
