Self-heating and spontaneous-ignition screening for reactive porous media (lagging fires) - Frank-Kamenetskii and Semenov criticality, critical thickness and surface temperature, induction time, Arrhenius fitting from basket tests (EN 15188 / ASTM E2021). USE WHEN: a flammable liquid leak onto insulation, oil-soaked lagging, spontaneous combustion, smouldering, a fire with no obvious ignition source, or insulation choice driven by absorbency. Anchors on neqsim.process.safety.selfheating.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NeqSim Self-Heating and Spontaneous Ignition Skill Screening for **low-temperature self-heating leading to spontaneous ignition** — the mechanism behind *lagging fires*, where a combustible liquid soaks into porous thermal insulation and ignites with no external ignition source. ## When this skill applies Reach for this skill when you see any of these signals: - A fire or smoke event on insulated pipework, vessels or valves with **no identified ignition source**. - A leak of a combustible liquid — glycol (MEG/DEG/TEG), heat-transfer oil, lubricating oil, hydraulic fluid, amine, diesel — onto or into **porous insulation** (mineral wool, glass wool, calcium silicate, perlite). - Questions phrased as *"can this liquid self-ignite?"*, *"is this insulation safe?"*, *"how thick can the lagging be?"*, *"why did it catch fire hours after the leak stopped?"* - A request to interpret **oven / basket / hot-storage test** results, or to extrapolate small-scale test data to plant scale. ## The one thing to get right **Self-heating is a size-dependent problem, not a temperature-only problem.** Heat is generated throughout the volume (scales with $r^3$) but lost through the …

How to install
mdr add equinor/neqsim/neqsim-self-heating-ignition@sha256:617d63dbfc23b840The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
