How do you calculate a cryogenic compliance burden score?

Multiply the severity, occurrence, and detection scores on a consistent scale. With severity 6, occurrence 4, and detection 3 the example produces a burden score of about 4.55 on the calculator's normalized scale, driven mostly by the high severity.

What is a good compliance burden score for cryogenic hazards?

Lower is better. There is no universal threshold, but set an internal action line and treat anything above it as requiring a control upgrade. For cryogenic work, any item with top-band severity warrants review regardless of total.

What do severity, occurrence, and detection mean here?

Severity rates the consequence of a cryogenic event such as asphyxiation or brittle fracture, occurrence rates how likely it is, and detection rates how well current controls catch or prevent it. A high detection score means controls are weak, raising the burden.

RPN vs cryogenic compliance burden, what is the difference?

It is the same multiplicative RPN logic from FMEA, scoped to cryogenic and LNG hazards like ODH, relief, and venting. Using one consistent scale lets you compare a PPE gap against a relief-valve gap on equal footing.

Why does severity dominate the example score?

At severity 6 with occurrence 4 and detection 3, the product is led by the consequence term. For cryogenic hazards that is intentional: an oxygen-deficient atmosphere is rare but fatal, so even modest occurrence and detection should not bury it.

How should I act on a high detection score?

A high detection score signals your existing controls are unlikely to catch the hazard in time. Prioritize adding independent layers such as fixed oxygen monitors, relief verification, or interlocks, which lowers detection and the overall burden.

Cryogenic Storage & LNG Equipment calculator

Cryogenic Safety Compliance Burden Calculator

The cryogenic compliance burden score is a risk priority number (RPN) adapted for LNG and cryogenic storage hazards: oxygen-deficient atmospheres, cold burns, brittle fracture, relief and venting failures, and pressure-buildup events. EHS leads and process safety engineers use it to rank which compliance gaps to close first when budgets and downtime are limited. Because cryogenic incidents can be sudden and life-threatening, a structured severity x occurrence x detection score keeps the team from fixing the loud problem instead of the dangerous one. It turns a wall of audit findings into a defensible priority list.

What this calculator does

Score the relative burden of cryogenic safety compliance actions such as relief review, oxygen-deficiency controls, vent routing, training, or permit gaps.
Use it when cryogenic safety compliance burden in cryogenic storage and lng equipment needs a defensible ranking against other cryogenic storage and lng equipment risks for the next review.
It multiplies hazard severity, occurrence likelihood, and current control detection into a single cryogenic risk priority score for ranking compliance actions.

Formula used

Cryogenic compliance burden score = severity × occurrence × detection
Use the same scoring scale when comparing relief, venting, ODH, PPE, and training actions.

Inputs explained

Cryogenic hazard severity score:
Hazard occurrence likelihood score:
Existing control detection score:

How to use the result

Use it during process hazard analyses, ODH assessments, relief-system reviews, or when prioritizing a backlog of safety findings across a cryogenic facility.
It is an ordinal ranking tool, not an absolute risk measure; the same total can come from very different cause profiles, so a high-severity item may deserve action even at a modest score.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
