Inspect LPG installations as systems, not isolated tanks

Treat this document as a focused evidence review: Inspect LPG installations as systems, not isolated tanks. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 29 CFR 1910.110 – Storage and handling of liquefied petroleum gases from Occupational Safety and Health Administration via eCFR supports the following bounded statements:

• Under 29 CFR 1910, the filling connection and the vent from the liquid level gages in containers, filled at point of installation, must not be less than 10 feet in any direction from air openings into sealed combustion system appliances or mechanical ventilation air intakes. The research record locates this support at 29 CFR 1910.110(b)(14)(vii) (eCFR anchor p-1910.110(b)(14)(vii)).
• Under 29 CFR 1910, the rule requires that valves in the assembly of multiple container systems be arranged so that replacement of containers can be made without shutting off the flow of gas in the system. The research record locates this support at 29 CFR 1910.110(c)(6)(i) (eCFR anchor p-1910.110(c)(6)(i)).

Keep the evidence boundary at these traced claims. They support a review of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths; they do not support conclusions outside the source’s stated conditions.

What the source does not establish

Federal workplace rule; container type, use, location, fire code, supplier instructions, and incorporated standards affect applicability. Do not read the source as proof of implementation or permission to change production. Its guidance remains conditional on identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders and the environment’s recorded constraints.

Applicability questions

• For source statement 1 at 29 CFR 1910.110(b)(14)(vii) (eCFR anchor p-1910.110(b)(14)(vii)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 29 CFR 1910.110(c)(6)(i) (eCFR anchor p-1910.110(c)(6)(i)), which observable configuration, record, or test can confirm applicability here?
• Which deployed instance of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths will be compared with the source, and why that instance?
• How will the review distinguish a source mismatch from a failure in identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders?
• Who approves the conclusion, exception, test window, and rollback threshold?

DSE recommendation:

DSE recommends using the cited source as the evidence anchor for this decision. Anchor the review in the cited section and keep observation separate from interpretation. Record the source location, examined part of critical rooms, power, cooling, water, fire protection, alternate sites, physical barriers, and documented recovery paths, observed and expected states, owner, and reason for deviation.

Do not move from citation to production in one step. Pilot the decision where practical, observe agreed signals, retain a reversal point, and verify identity and access control, Windows DNS where networked services use it, time, communications, utilities, life-safety systems, vendors, and authorized responders. Handle credentials, keys, recovery data, and personal information through approved secure channels.

Verification and evidence

Tie each conclusion back to 29 CFR 1910.110(b)(14)(vii) (eCFR anchor p-1910.110(b)(14)(vii)); 29 CFR 1910.110(c)(6)(i) (eCFR anchor p-1910.110(c)(6)(i)) and to observable material such as facility inventories, inspection records, alarm and shutdown tests, maintenance history, recovery exercises, and corrective actions. Preserve provenance and stable identifiers without copying secrets into the evidence set.

Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee.
