Hot Work Permit in Cantiere: Coordinamento Nave-Bacino
Enclosed-space entry criteria non equivalgono a Safe for Hot Work; certifier, atmosphere/residue limits, isolations, adjacent-space tests e retest frequency derivano da host-yard law e coordinated permit system.
Spiegazione operativa
Enclosed-space entry criteria non equivalgono a Safe for Hot Work; certifier, atmosphere/residue limits, isolations, adjacent-space tests e retest frequency derivano da host-yard law e coordinated permit system.
Riferimento normativo
Host jurisdiction and yard law; ship SMS; MSC.581(110) only for concurrent enclosed-space entry; OSHA 29 CFR 1915.14 only as US example.
Campo di applicazione
Hot work during repair. Authorized person depends on jurisdiction, space history/type and yard duties; an SMS designation cannot override marine chemist/local statutory certification.
Procedura / Come si compila
- Identify host law, yard permit and authorized certifier.
- Test residues, atmosphere, adjacent/connected spaces and oxygen enrichment to hot-work criteria.
- Isolate systems and establish fire watch/communications.
- Retest at required frequency and after condition changes.
- A ship officer performs only checks expressly authorized within competence.
- Use actual yard/SMS risk categories, not universal minor/moderate/major.
Esempio pratico
A tank may be safe for entry but not safe for ignition work; hot-work certification follows the competent person required by local law.
Cosa va tipicamente storto
Use MSC.581 entry values as universal hot-work certificate or allow any SMS-designated officer to declare gas-free despite statutory certifier requirements.
