HoodProof: Hood Cleaning Log

excessive capitalisation._

HoodProof is an offline kitchen exhaust cleaning log for hood cleaning

contractors, restaurant facilities managers and multi-site operators. It maps

an exhaust system zone by zone, records grease readings under the standard the

site is worked to, pairs before and after photographs to each zone, and

produces the cleaning report the customer is handed. The core logging and PDF

workflow needs no signal and no account.

Two standards, two different measurements

NFPA 96 and BESA TR19 Grease both look at grease deposits, but the measurement

method, the units and the decision rules differ. NFPA reads accumulated grease

depth with a grease depth gauge comb. TR19 uses wet film thickness testing, and

deposit thickness testing where deposits are hard or carbonised. HoodProof

renders one standard's scale at a time, labelled with its instrument, so a

reading is never entered against the wrong rule. Each site is set to its own

standard, and every visit stamps the standard it was measured under, so

switching a site never re-judges a record you have already signed.

The figures it works to

• NFPA 96: cleaning is required where a measured depth of 0.078 in (2,000 µm)

is observed, or 0.125 in (3,175 µm) in a fan housing, and surfaces are cleaned

to a maximum of 0.002 in (50 µm). HoodProof judges the fan housing against its

own figure rather than the surface one.

• TR19 Grease: the mean must not exceed 200 µm between scheduled cleans, a

point at 500 µm or above needs local or spot cleaning, and representative

post-clean measurements must not exceed 50 µm.

Readings are compared against the limits of the standard you selected. Neither

standard defines a whole-system pass or fail, so the summary the app shows is

its own, of the most severe surface, and it says so.

What it does

• Six zones per system, from the hood canopy and baffle filters to the upblast

fan bowl. Six zones is HoodProof's workflow, not a division either standard

prescribes.

• Every zone is measured twice: once on arrival, once after cleaning. The

post-clean reading is what verifies the clean, and an event with none is

recorded as not verified rather than passed.

• A measurement dial that shows the active standard's scale only, with the

figures that standard sets marked on the face.

• Before and after photographs paired to each zone.

• An inaccessible section register. Log each section you could not reach, why,

and a photograph, with the corrective recommendation. It is reproduced on the

report under its own heading, so the record shows exactly what the report

covers.

• A service checklist covering belt tension, hinge kit, electrical disconnect

and lockout, grease drip cup and access panel gaskets. It is HoodProof's

checklist, not a complete NFPA 96 inspection.

• A cleaning report as a PDF, carrying the zone reading table, the photo pairs,

the inaccessible register, your company details and the technician signature.

Plus a printable hood service label showing the clean date, the next due date

and your company name, address and phone.

• Inspection intervals from NFPA 96: monthly for solid fuel, quarterly for

high-volume, semi-annually for moderate-volume and annually for low-volume

operations. NFPA schedules the inspection and cleaning follows from what it

finds, so HoodProof tracks the inspection due date and records the clean

separately. Reminders at 30, 14 and 3 days.

What it is not

HoodProof is a record-keeping and measurement-logging tool. It reduces

paperwork and organises cleaning evidence. It does not substitute for a

competent inspection, it does not certify anything, and a report it produces

covers only the sections actually accessed and recorded. It is not affiliated

with NFPA or BESA.

Standard tier covers one site with one exhaust system and three cleaning

visits, and shows ads. Records you have already made stay readable.
