LEV360™ is a governance standard concerned with how exposure control using Local Exhaust Ventilation (LEV) is defined, evidenced, and assured. It exists to establish a clear and consistent framework for determining whether exposure control can be supported from available evidence.
LEV360 does not deliver technical services. It defines governance expectations and assurance outcomes that apply across the full lifecycle of LEV systems, from end-user operation through to exposure control at the point of work.
Purpose of the Standard
LEV360 exists to address a persistent gap between the presence of LEV systems and the ability to demonstrate that exposure is being controlled in practice.
The standard is intended to:
- remove ambiguity from exposure control assurance
- separate evidence from opinion
- support consistent governance decisions
- enable defensible statements about control status
LEV360 is outcome-focused. It is not concerned with how work is sold, delivered, or procured.
Scope
LEV360 applies to the governance of exposure control where LEV is used as a control measure. This includes, but is not limited to:
- use of LEV by end users
- management oversight and responsibility
- design intent and suitability
- installation, modification, and change
- examination, testing, and maintenance
- training, competence, and supervision
- record integrity and governance continuity
LEV360 does not replace legal duties, statutory requirements, or recognised technical guidance. It provides a structured governance framework within which those duties can be evidenced and reviewed.
Nature of the Standard
LEV360 is intentionally positioned above operational activity.
It does not:
- specify methods of work
- prescribe technical solutions
- provide or commission services
- validate commercial competence
- replace professional judgement
Its function is to define what must be demonstrable, not how activities are performed.
Governance Across the Exposure Control Chain
LEV360 recognises that exposure control is the result of multiple interacting elements over time. No single activity, document, or test result is treated as sufficient in isolation.
The standard therefore addresses governance across:
- system use and behaviour
- management and oversight
- technical control and suitability
- continuity and change
LEV360 aligns these elements into a single governance framework so that exposure control can be considered as a current condition, not a historic assumption.
Evidence and Assurance
LEV360 operates on the principle that exposure control can only be asserted where it is supported by coherent and current evidence.
The standard defines the expectation of evidence without publishing the criteria by which evidence is evaluated. Evidence is considered in aggregate and in context.
LEV360 does not rely on:
- narrative assurance
- isolated artefacts
- implied compliance
- historic acceptance
Evidence is treated as a governance matter, not an administrative output.
Verification and Status Outcomes
LEV360 provides a status-based outcome framework to support governance decisions relating to exposure control.
Status outcomes are derived from a protected verification process designed to ensure consistency and integrity while preventing manipulation or reverse engineering.
Status outcomes are assigned using protected verification rules.
Detailed criteria, thresholds, and decision logic are not publicly disclosed.
Status Descriptors
Controlled
An outcome indicating that available evidence supports the conclusion that exposure control is being achieved for the conditions assessed.
Restricted
An outcome indicating that the available evidence does not support full assurance of exposure control, or that uncertainty exists which limits defensible assurance.
Unsafe
An outcome indicating that exposure control cannot be supported from the available evidence.
Independence and Integrity
LEV360 is structured to remain independent of delivery, procurement, and commercial influence.
The standard is designed to:
- produce consistent outcomes regardless of who performs work
- resist selective compliance or optimisation for appearance
- remain defensible under external scrutiny
- preserve the integrity of exposure control assurance
LEV360 does not publish internal verification criteria or decision mechanics. This is deliberate and fundamental to the credibility of the standard.
Relationship to Legal and Regulatory Frameworks
LEV360 aligns with established legal duties relating to the control of hazardous substances and the use of LEV.
It does not reinterpret or supersede law.
It provides a governance structure through which assurance decisions can be made and reviewed.
