DAILY SAFETY STEPS
The 4K-4 vessel is a high-pressure apparatus and should be treated with care.
• Handle the vessel over a table or solid surface.
• Do not drop a vessel.
• Do not overfill a vessel with oxygen: The maximum oxygen filling pressure is 30bar / 3000kPA, which
is the standard for bomb calorimetry.
• Do not use any tools to open or close the vessel. If the vessel fails to deflate use the pre-scribed
'emergency deflate' procedure as outlined in the CAL3K-F Operations Manual.
• Use the provided De-filler cap only, part number: 3K-3-22.
• Do not use any oil or grease on any of the oxygen fittings or the O-rings. A very small amount of high-
pressure (vacuum) grease is allowed on the O-ring to make them pliable. Wipe them clean afterwards.
• Store the vessel with the lid open. Never store a vessel under pressure, always deflate using the de-
filler cap.
• Clean the inside of the vessel with paper towel after every use.
• Weigh the crucible every week and discard it when it has lost 10% of its original mass.
• Discard the crucible when the bottom is distorted and extremely discoloured.
• Remove the deflector plate every week and clean the top surface. It does accumulate residue and
must be clean regularly.
• Make sure to use the pipe-clamping device on the right side of the filing station for safe use.
