Preservation Monitoring

Preservation monitoring is the repeated, organised observation of a collectible and the conditions surrounding it to determine whether the object is stable, deteriorating, responding to risk or benefiting from preventive action. It turns condition documentation from a one-time snapshot into a dated history of change.

A condition assessment might record a 12 mm tear, slight fading and a repaired corner. Monitoring asks what happened next: did the tear extend, did the colour continue to shift, did the repair remain secure, and did a change of storage or display reduce the risk? That difference is fundamental. A defect can be old and settled, uncertain, newly active or worsening. The collector's task is not merely to notice imperfection, but to recognise meaningful movement in condition.

A useful private-collection programme does not require museum-level equipment. It requires a baseline worth returning to, repeatable photographs, proportionate inspection intervals, honest status language and a record that connects evidence to decisions. The aim is not paperwork for its own sake. It is to recognise deterioration early, demonstrate stability when it exists and preserve a credible account of responsible custody.

Core principle

Record the object clearly enough today that meaningful change can be recognised tomorrow.

Effective monitoring is dated, repeatable, evidence-led, proportionate, non-destructive, connected to risks, linked to action and preserved as a chronological history.

Orientation

From snapshot to history

The collector journey is a repeating evidence cycle, not a single inspection.

Establish the reference state

Create a baseline that is specific enough for a later examiner to recognise change rather than merely recognise the object.

Observe the object and its setting

Inspect the collectible, its enclosure, its support, its storage or display position and the conditions capable of affecting it.

Compare like with like

Use previous notes, measurements and repeatable photographs. Do not rely on memory or compare images made under incompatible conditions.

Classify the change honestly

Record no change, possible change, confirmed change, active deterioration, stabilised condition or a lack of comparability.

Act and test the result

Continue monitoring, reduce a risk, improve support or enclosure, isolate the item, obtain specialist advice, and record whether the response worked.

Collector scenario: a box corner that stopped being ordinary wear

A collector records an 18 mm split at the upper-right corner of a boxed game. The split appears old, the edges are firm and the box remains usable. Six months later, a repeat photograph shows a 24 mm split. The corner now opens under its own weight, and a small abrasion has appeared where the lid rubs the base.

The first record described damage. The second establishes change. That changes the judgement from "historic wear" to "active structural deterioration". The collector can now reduce shelf pressure, support the corner, restrict handling, record the intervention and check whether the split stops extending.

Monitoring has not identified one universal cause or authorised a repair. It has done something more important first: it has shown that the problem is moving and that passive observation is no longer enough.

Evidence discipline

Separate observation, interpretation and cause

A strong monitoring record says what was found, what it may mean and how confident the conclusion is.

Observable fact

What can be seen or measured

The upper-right box-corner split measures approximately 24 mm. It measured 18 mm in the previous record. The corner opens by about 3 mm under the box's own weight.

Interpretation

What the observation may mean

The split appears active and may be progressing because the corner is carrying unsupported load. This is a reasoned judgement, not the same thing as a confirmed cause.

Possible contributor

What may have helped produce the change

Shelf pressure, repeated handling, weak original board, an earlier impact or humidity-related movement may have contributed. The record should preserve alternatives unless evidence distinguishes them.

Collector decision

What should happen next

Reduce pressure, provide support, limit handling, photograph the corner under repeatable conditions and review sooner. Seek specialist advice if the structure continues to fail or an intervention is contemplated.

Environmental readings and object change often occur together, but correlation is not automatically causation. New corrosion after repeated high-RH events may be consistent with moisture-related activity. A stronger conclusion becomes possible if the record shows the same pattern repeatedly, excludes an alternative moisture source and records reduced change after improved control. Even then, terms such as "consistent with", "likely associated with" or "may have contributed" are often more accurate than "caused by".

Uncertainty is not a weakness in the record. "Possible change - photography not comparable" is more useful than an unsupported claim of stability. Monitoring is credible when its language matches the quality of its evidence.

Judgement

Stable damage, uncertain change and active deterioration

The central preservation question is not whether an object is perfect, but whether its condition is changing and what that change threatens.

No change observed

Meaning: No visible or measurable change from the previous comparable record.

Collector response: Continue the current care arrangement and retain the dated observation as evidence of stability.

Possible change

Meaning: A difference may be present, but lighting, angle, access or measurement quality is insufficient to confirm it.

Collector response: Do not overstate the conclusion. Improve the comparison method and schedule an earlier recheck.

Minor confirmed change

Meaning: A small change is established, but it does not presently threaten structural integrity, completeness or safe handling.

Collector response: Record the extent, consider a low-risk preventive adjustment and monitor more frequently until the pattern is understood.

Significant change

Meaning: Deterioration is affecting stability, appearance, completeness, function or an important original surface.

Collector response: Reduce exposure or handling, identify immediate risks and consider specialist assessment.

Active deterioration

Meaning: Damage is continuing, recurring or convincingly likely to continue without intervention.

Collector response: Treat this as an action state rather than a descriptive label. Stabilise the situation and escalate according to urgency.

Stabilised

Meaning: Previously active change appears to have stopped following an action, but the conclusion remains provisional.

Collector response: Keep monitoring. One quiet inspection does not prove permanent stability.

Not comparable

Meaning: The current examination cannot be reliably tested against the earlier record.

Collector response: State why: changed lighting, rearranged parts, missing measurements, treatment, inaccessible surfaces or a different photographic view.

Stable does not mean original, valuable or harmless

An old chip, closed tear, historic stain, secure repair or settled distortion may be stable. Stability says something about current activity, not about age, authenticity, desirability or market impact. Conversely, a visually minor change can be serious if it affects an original surface, spreads rapidly or signals a wider collection risk.

This distinction prevents two opposite mistakes: treating every imperfection as an emergency, and dismissing a small but active defect because it does not yet look dramatic.

Baseline

Create a reference state that can be tested

A baseline should allow a future examiner to decide whether the object changed, not merely remind them that a defect existed.

Weak baseline

"Good condition with some wear."

This is subjective, does not locate a defect and cannot be meaningfully tested later.

Testable baseline

"Front cover has a 12 mm diagonal crease beginning 18 mm from the lower-right corner. The crease is visible under raking light but has not broken the printed surface."

The feature, location, extent and visible consequence can all be compared later.

A monitoring-ready baseline should normally identify

•Unique object or inventory identifier

•Title, maker, publisher, edition, issue or variant where relevant

•Materials, construction and components

•Dimensions, weight or completeness where useful

•Current storage or display location and enclosure

•Overall condition and individually located defects

•Dated overall and detail photographs

•Examiner, method and limitations

•Known vulnerabilities and preservation recommendations

•Proposed review date or event trigger

Recognition

What to monitor on the collectible

Inspect the object by condition axis. The useful question is not only what damage exists, but what feature could change first if a known risk becomes active.

Structure and attachment

Observe

Cracks, splits, tears and losses
Loose joints, hinges, sewing and fasteners
Delamination, lifting layers and failed bonds
Distorted supports, unstable mounts and detached parts

Compare

Measure length, width, opening, movement or the number of newly detached elements from fixed reference points.

Warning sign

A defect that opens under its own weight, lengthens, sheds material or transfers stress to adjacent original material is not merely cosmetic.

Surface and finish

Observe

Abrasion, scratches, gloss loss and polishing
Powdering, flaking, lifting paint or print
Sticky deposits, bloom, haze and oily films
Dust, soot, stains, fingerprints and accretions

Compare

Use repeatable close-ups, raking light and an annotated boundary where an affected area may spread.

Warning sign

Do not clean first. Surface material may be evidence of corrosion, mould, pest activity, historic use, manufacturing residue or an earlier treatment.

Colour and optical appearance

Observe

Fading, yellowing, darkening and bleaching
Uneven exposure, dye migration and colour shift
Clouding, loss of transparency and tarnishing
Changes in fluorescence or reflective appearance

Compare

Use controlled photography with consistent light, exposure, orientation and a suitable reference. Specialist measurement may be warranted for exceptional light-sensitive objects.

Warning sign

Visual memory is unreliable. A different white balance, background or light source can imitate colour change.

Shape and dimensions

Observe

Warping, bowing, cockling and curling
Shrinkage, swelling, sagging and compression
Misalignment, stretching and permanent deformation
Case, tray, mount or panel movement

Compare

Use consistent dimensions, a profile photograph, a straight edge, a template or a reference grid without forcing the object flat.

Warning sign

Changing shape may indicate moisture response, heat, load, poor support or internal material instability. Forcing correction can create fresh damage.

Material-specific activity

Observe

Corrosion products, pitting and lifting plating
Paper embrittlement, foxing-like spots and tape change
Plastic sweating, odour, brittleness and additive migration
Leather powdering, textile fibre loss and foam breakdown

Compare

Track the affected location and extent, but avoid treating colour or odour alone as a definitive chemical identification.

Warning sign

Composite objects can contain materials with conflicting needs, and one component can damage another through contact, emissions, staining or mechanical stress.

Function and operation

Observe

Battery leakage and connector corrosion
Cracked casings, cable embrittlement and screen change
Magnetic-media deformation and label loss
Hardware, firmware, software and file-integrity dependencies

Compare

Record test dates, method, equipment, software version, checksums or migration history where functional preservation is part of the object's significance.

Warning sign

Operational testing is not automatically harmless. Powering an unstable historic device or moving a seized mechanism may cause damage.

Known defects

Give each significant defect a repeatable identity

A defect identifier lets the same feature be tracked through multiple inspections without rewriting or confusing its history.

Example defect register

D01 - upper-left cover crease
D02 - tear at lower spine
D03 - stain on reverse
D04 - loose internal tray
D05 - corrosion on right fastener

Track for each defect

Type, component and exact location
Dimensions, severity and extent
Activity status and confidence
Date first observed and last checked
Photographs and measurement points
Change since the previous inspection
Action taken and follow-up result

Measure only what improves judgement

Linear measurements suit cracks, tears, gaps and detached edges. Area overlays can be more useful than guessed percentages for fading, mould, corrosion, paint loss or staining. Counts may suit flakes, pest sightings, new cracks or missing components. Profile photographs and templates can record bowing or sagging.

False precision is not an advantage. Domestic scales, flexible rulers, changing camera angles and inconsistent reference points can produce numbers that look authoritative without being comparable. Record method and uncertainty alongside the result.

Photographic evidence

Photograph for comparison, not decoration

A single photograph records appearance. A repeatable series can reveal change - provided the image-making process does not create false differences.

Repeat the view

Keep orientation, camera distance, focal length, object position and lighting direction as consistent as practical.

Give detail a location

Pair close-ups with an overall or contextual image so a future reader can find the monitored area.

Use references carefully

A metric scale, grey card, colour target, object identifier, date or defect number can improve comparison, provided it does not touch or obscure a sensitive surface.

Keep originals

Retain the unaltered capture and create a separate annotated derivative for boundaries, crack paths or measurement points.

Record limitations

A photograph may not show looseness, brittleness, odour, tackiness, depth or fine lifting. Written observation remains necessary.

Do not create risk for the image

Avoid unnecessary flash, heat, ultraviolet, infrared, unframing or manipulation merely to obtain a more dramatic photograph.

Image integrity record

Preserve the original file, capture date, photographer, file name, link to the inspection and backup location. If an image is cropped, exposure-corrected or annotated, keep the original and describe the derivative. Editing must not remove stains, cracks, colour differences, surface irregularity or shadows that reveal deformation.

When photographs are not comparable, say so. "Red lettering appears less saturated, but lighting and white balance differ; possible change only" is a stronger record than "more faded".

Environment

Monitor the object and the conditions around it

Environmental data explains exposure and helps test risk, but it never substitutes for inspecting the collectible itself.

Temperature

Track trends, duration and location

Temperature influences reaction rates, relative humidity, biological activity and the behaviour of plastics, batteries, electronics and heat-sensitive media.

Record averages, minima, maxima and unusual events.
Note sensor location and proximity to windows, heaters or vents.
Link readings to the period in which object change was observed.

Relative humidity

Avoid universal target thinking

Incorrect or unstable RH may contribute to movement, warping, cracking, corrosion, mould, adhesive failure and lifting surfaces. Appropriate conditions depend on materials, construction, history and feasibility.

Record the rate and duration of change, not only an average.
Consider enclosure microclimates and nearby moisture sources.
Treat composite objects as potentially conflicting systems.

Light and ultraviolet

Exposure is intensity multiplied by time

Light damage is cumulative and often irreversible. Low intensity over a long display period can still matter, and the object's actual position is more relevant than a general room reading.

Record display dates, daylight, lamp type and hours exposed.
Repeat photographs under controlled conditions.
Do not assume modern lighting means zero risk.

Water and moisture

Monitor incidents and their aftermath

Leaks, condensation, wet enclosures and damp building fabric can create immediate and delayed risks. The follow-up period is part of the incident record.

Record source, duration, affected objects and immediate response.
Photograph before disturbance where safe.
Continue checks for mould, staining, distortion and corrosion.

Pests and mould

Identify evidence before treatment

Live insects, larvae, cast skins, webbing, frass, grazing, fuzzy growth, spots, odour and increasing deposits can all matter, but not every powder or stain is biological.

Map where evidence was found and whether it is new.
Quarantine or isolate without spreading contamination.
Avoid applying domestic pesticides directly to collectibles.

Dust, pollutants and physical force

The enclosure and support are part of the evidence

Dust, off-gassing, contact materials, overcrowding, vibration, unsupported weight and repeated handling can create slow, localised damage even where room readings seem acceptable.

Inspect boxes, sleeves, foams, dividers, labels and fasteners.
Record load, contact points, movement and transport incidents.
Compare the object before and after display, loan or relocation.

Do not confuse acceptable room conditions with object stability

A room can appear acceptable while one object deteriorates because of trapped moisture, incompatible packaging, contact with another material, a historic treatment, internal instability, localised light or heat, pest activity inside an enclosure or unsupported physical stress.

The reverse is also true: an environmental excursion does not prove that damage occurred. It identifies exposure and justifies inspection. The object record and the environmental record become meaningful when they are read together.

Storage, display and handling

The preservation system is larger than the object

Boxes, sleeves, frames, mounts, supports, shelves and handling routines can either control risk or quietly create it.

Storage

Inspect the enclosure and neighbouring materials for compression, trapped moisture, acidic or dye transfer, adhesive failure, foam breakdown, rusting fasteners, dust entry, pest evidence and deformation.

Record when a sleeve, box, board, divider or storage location changes, because that change creates a new preservation context.

Display

Record display dates, object position, mount and support, light exposure, nearby heat, security, vibration, cleaning arrangements, inspection frequency and planned rotation.

Recheck seasonally: direct sunlight, condensation, dust entry and support movement can change without the display appearing visibly altered at first.

Handling

Document frequency, purpose, supports, opening limits, component removal, photography, demonstrations, packing, unpacking and incidents.

Avoid universal rules. Clean hands, gloves, trays, cradles and assistance each have roles depending on the object and task.

Frequency

Set the inspection schedule by risk

The same interval should not be applied to every object. Review frequency follows likelihood, consequence, uncertainty and recent change.

Immediate or very frequent

Suitable for: Wet objects, active mould, live pest activity, spreading corrosion, battery leakage, unstable flaking, severe structural failure or objects under quarantine.

Approach: Inspect as the incident response requires, then at short intervals until stability is demonstrated.

Weekly to monthly

Suitable for: Recently treated objects, newly installed displays, known leaks, suspected active defects, sensitive objects in a changing environment or a new storage arrangement.

Approach: Use a defined short review period rather than an indefinite high-intensity routine.

Quarterly to six-monthly

Suitable for: Important displayed items, vulnerable paper or textiles, composite objects and apparently stable known defects exposed to seasonal change.

Approach: Align checks with seasonal transitions or planned display rotations where useful.

Annual

Suitable for: Stable items in good enclosures, controlled storage, robust materials and objects handled infrequently.

Approach: Record that the inspection occurred even when no update beyond 'no change observed' is required.

Event-triggered

Suitable for: Before and after transport, loan, display, treatment or sale; after leaks, pest sightings, building work, HVAC failure, heatwaves, accidental handling or packaging changes.

Approach: The event overrides the routine calendar because it creates a new reference point or risk exposure.

A proportionate private-collector programme

Tier 1 - Basic

Baseline photographs, short condition description, storage location, annual review and incident notes for ordinary stable items.

Tier 2 - Enhanced

Defect map, measured features, controlled photography, six-monthly review and nearby environmental logging for valuable or vulnerable items.

Tier 3 - Specialist

Professional assessment, calibrated equipment, tailored display limits, conservation planning and frequent review for exceptional or actively deteriorating objects.

Decision and response

Monitoring must lead somewhere

A record has limited preservation value if a confirmed problem is documented repeatedly but no decision follows.

Routine

Continue and document

Use when a defect is stable, comparison is reliable and the existing arrangement is performing as intended.

Monitor

Increase attention

Use when change is possible, comparison quality is weak or a new storage, display or treatment state needs to settle.

Planned action

Reduce a known preventable risk

Improve an enclosure, support, housekeeping routine, light exposure, handling method or storage location without undertaking treatment of the object itself.

Urgent

Stabilise and obtain advice

Use for increasing cracks, recurring condensation, progressive fading, failing repairs, unstable mounts or substantial environmental excursions.

Immediate

Protect people, object and collection

Use for water, active mould, live pests, severe collapse, hazardous contamination, leaking batteries, active corrosion or loss of original surface.

Test whether the action worked

A preservation action should have an expected result. A new enclosure may aim to reduce dust, abrasion and movement. Reduced display exposure may aim to prevent further visible fading. Improved humidity control may aim to reduce extreme excursions and dimensional movement. A pest response may aim to reduce trap counts and eliminate new damage.

Record the action, date, person responsible, materials or method, photographs, limitations and follow-up date. Then state whether the expected result was achieved. Without follow-up, an intervention becomes another untested assumption.

Documentation

Build a monitoring event that preserves chronology

Each inspection should create a new dated entry. Earlier assessments should remain visible rather than being overwritten.

Minimum monitoring record

•Object identifier and title

•Inspection date, examiner and location

•Reason for inspection and previous record consulted

•Overall stability and change status

•Known defects checked and new defects found

•Measurements and comparison method

•Photographs and file references

•Environmental or incident context

•Storage, display and enclosure condition

•Action required, priority and person responsible

•Outcome of any intervention

•Next review date and unresolved uncertainty

Compact controlled vocabulary

Term	Use
Unchanged	Comparable evidence shows no confirmed change.
Worsened	A known defect has increased in extent, severity or activity.
New defect	A feature absent from a comparable earlier record is now present.
Suspected active	Evidence suggests continuing deterioration but is not yet conclusive.
Stabilised	Previously active change appears to have stopped after action.
Uncertain	The observation or its significance cannot presently be resolved.

Weak change statement

"Box getting worse."

Evidence-led change statement

"The upper-right corner split increased from 18 mm to approximately 24 mm. The corner now opens by about 3 mm under the box's own weight. Condition is recorded as active."

Collection intelligence

Link object records to collection-level events

Not every observation needs to be duplicated across hundreds of object records. Shared exposure can be documented once and linked to affected items or zones.

A collection-level monitoring record may cover room temperature and RH, pest traps, leak inspections, cleaning, filter changes, building works, HVAC faults, storage upgrades, seasonal risks and emergency incidents. Objects or storage zones can then be linked to the event.

This structure also reveals patterns. One warped object may be an isolated material problem. Several warped objects in the same cupboard may point to a storage or moisture issue. Multiple affected items turn individual condition observations into evidence about the collection environment.

Suggested data structure

Monitoring event

Event ID, object ID, inspection date, examiner, reason, location, overall status, change status, urgency, summary and next review date.

Defect observation

Defect ID, type, component, location, dimensions, severity, activity, confidence, change from previous and notes.

Environmental context

Temperature, RH, light, moisture, pests, pollutants, source of readings and monitoring period.

Action and outcome

Required action, priority, responsible person, target date, completion, related treatment or incident and follow-up result.

Specialist threshold

Know when collector monitoring should stop and escalation should begin

Monitoring should be as non-invasive as possible. It should not become amateur treatment, hazardous exposure or repeated testing that worsens the object.

Active or spreading biological growth

Potential mould combines collection risk with health and safety. Isolate the object and avoid brushing, vacuuming or applying chemicals without an appropriate plan.

Unstable original surfaces

Flaking paint, friable decoration, powdering leather, lifting print or shedding material can be worsened by ordinary handling and photography.

Water, salts or unexplained corrosion

Drying, cleaning or chemical treatment can alter evidence and may accelerate damage if the material system is misunderstood.

Degrading plastics, foams and batteries

Sticky surfaces, strong changing odours, sweating, cracking, crumbling foam or leakage may require isolation, ventilation, hazardous-material awareness or tailored storage.

High-value, unique or structurally complex items

The lower the tolerance for loss and the harder the object is to replace, the stronger the case for a professional condition assessment and tailored plan.

Any proposed treatment that changes original material

Cleaning, flattening, consolidation, adhesive work, corrosion removal, repainting or repair belongs primarily to conservation or restoration practice, not routine monitoring.

Myth and reality

Correcting common assumptions

Myth

A stable room reading proves the collection is safe.

Reality

An individual object may still deteriorate because of incompatible packaging, trapped moisture, internal instability, residual contamination, contact materials or localised stress.

Myth

An environmental excursion proves damage occurred.

Reality

The excursion records exposure and risk, not automatic damage. The object still needs to be examined and compared.

Myth

Gloves are always safer.

Reality

The safest handling method depends on material and task. Poorly fitting gloves can reduce dexterity, while clean dry hands may be unsuitable for metals, photographs or highly sensitive surfaces.

Myth

No change means the inspection was pointless.

Reality

Repeated evidence of stability validates the current care arrangement and gives later change a clearer starting point.

Failure modes

Common mistakes that weaken the record

Treating a condition report as timeless

A report records one examination under particular circumstances. Handling, ageing, transport, display, storage and treatment can all alter the object later.

Better practice: Date every record, retain earlier versions and create a new monitoring event rather than overwriting the past.

Using grades as the monitoring record

Excellent, good, fair and poor do not locate a defect or show what changed.

Better practice: Retain the summary grade if useful, but document the feature, extent, location and reason for any grade change.

Taking inconsistent photographs

Different angles, scales, backgrounds, lighting and white balance can manufacture an impression of movement or fading.

Better practice: Repeat views and state when a comparison is not reliable.

Collecting environmental data without reviewing it

A logger full of readings is not a preservation programme. It does not prove that damage occurred or explain what should change.

Better practice: Review trends, connect them to material sensitivity and object observations, and test whether mitigation improves the pattern.

Assuming no visible change means no risk

Some deterioration is internal, chemical, microscopic, functional, concealed by packaging or too subtle for ordinary photography.

Better practice: Use risk knowledge and incident history alongside visual inspection, especially for plastics, electronics, batteries, composites and sealed enclosures.

Cleaning before documenting

Cleaning can remove evidence of corrosion, pests, mould, deposits, residues, use and earlier treatment.

Better practice: Document first, then decide whether cleaning is safe, necessary and within collector competence.

Confusing patina with active deterioration

Historic wear, stable tarnish and aged surfaces may be meaningful evidence rather than defects to erase.

Better practice: Monitor whether the surface is changing before assuming it should be treated.

Over-monitoring

Repeated opening, unframing, flexing, powering, moving or testing can itself become the main source of damage.

Better practice: Use the least invasive method and the lowest frequency that still answers the preservation question.

Other domains

What preservation monitoring can and cannot prove

Authentication

Monitoring may record natural ageing, repairs, altered labels or component substitutions after acquisition. It does not prove authenticity: fakes can age, and genuine items can remain unusually well preserved.

Grading

A grade may change because of new fading, tears, corrosion, missing components, failed restoration or loss of function. Retain both the earlier grade and the reason for revision.

Value and insurance

A chronological record can strengthen disclosure, condition evidence and the timing of damage. It can also document deterioration that reduces value. The language should remain factual rather than promotional.

A practical annual review for a private collection

Review each priority item, or a sensible group of lower-risk items, for:

•New damage or worsening old damage

•Mould, damp or unusual odour

•Pest evidence or fresh debris

•Corrosion, powdering or sticky surfaces

•Fading, yellowing or uneven exposure

•Adhesive, repair or mount failure

•Enclosure and support breakdown

•Component movement or loss

•Storage-location risks and recent incidents

•Whether the next review date still matches the risk

Update the record where necessary, but always record that the inspection took place. A chronological sequence of "no change observed" entries is valuable evidence, not empty administration.

Key takeaways

A condition assessment records the present state; preservation monitoring tests whether that state changes over time.
The strongest records separate observable fact, interpretation, possible cause, confidence and collector action.
Stable historic damage and active deterioration require different responses, even when they look similar in a single inspection.
Object inspection and environmental monitoring must be connected, but neither automatically proves the cause of the other.
Repeatable photography, controlled vocabulary, defect identifiers and preserved earlier records make comparison credible.
Monitoring frequency should follow risk, consequence, uncertainty and events rather than a universal calendar.
The record should lead to a proportionate decision and later test whether the response worked.
Collectors should stop and seek specialist help when monitoring would require hazardous handling, invasive testing or treatment of unstable original material.
