Fill Limits, Labelling, Storage and Carriage
Control cylinder contents and mass, compatible construction, identification, valve protection, ventilation, securing and transport documentation.
Prepare from scope to safe handover
Start with category and territory, build the underpinning science, then use a controlled technical and record sequence while reserving hands-on competence for supervised practical preparation.
Core concepts
Concept 1
Control cylinder contents and mass, compatible construction, identification, valve protection, ventilation, securing and transport documentation.
Exam cue: Check cylinder approval, tare, current inspection and compatibility; identify contents, calculate the allowed fill, weigh during transfer, close and protect, then secure for storage or carriage.
Concept 2
Recovery-cylinder capacity is controlled by allowable fill and refrigerant density, not by filling the water volume completely.
Exam cue: Keep qualification category, work territory and practical authority visible throughout the decision.
Concept 3
A complete label and weight record protect downstream handlers from unknown, mixed or overfilled contents.
Concept 4
Carriage, storage and waste duties are separate from the 2079 category permission and must be checked under current law and carrier rules.
Targeted study blocks
Scope
Know what this topic controls
Control cylinder contents and mass, compatible construction, identification, valve protection, ventilation, securing and transport documentation.
Method
Use a repeatable evidence sequence
Check cylinder approval, tare, current inspection and compatibility; identify contents, calculate the allowed fill, weigh during transfer, close and protect, then secure for storage or carriage.
Boundary
Stop at the legal and practical limit
Carriage, storage and waste duties are separate from the 2079 category permission and must be checked under current law and carrier rules. Do not heat, roll or intentionally vent a cylinder to make space for more refrigerant.
Risk pitfalls and guardrails
Do not heat, roll or intentionally vent a cylinder to make space for more refrigerant.
Guardrail: Check the current official source and stop when the task exceeds the qualification or practical boundary.
Do not treat historical handbook legislation wording as the complete current workplace rule.
Guardrail: Check the current official source and stop when the task exceeds the qualification or practical boundary.

Fill Limits, Labelling, Storage and Carriage: safe method
Check cylinder approval, tare, current inspection and compatibility; identify contents, calculate the allowed fill, weigh during transfer, close and protect, then secure for storage or carriage.
Fill Limits, Labelling, Storage and Carriage: key fact 1
Recovery-cylinder capacity is controlled by allowable fill and refrigerant density, not by filling the water volume completely.
Fill Limits, Labelling, Storage and Carriage: key fact 2
A complete label and weight record protect downstream handlers from unknown, mixed or overfilled contents.
Fill Limits, Labelling, Storage and Carriage: scope boundary
Carriage, storage and waste duties are separate from the 2079 category permission and must be checked under current law and carrier rules.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
