ASTTBC PPE key terms

The way an applied science technologist carries out work: applying accepted methods, staying within their competence, keeping records, and taking responsibility for the quality and outcomes of their own technical decisions.

The boundary of work a technologist is legally and professionally permitted to perform, set by legislation, certification, employer authorization, and demonstrated competence. Work outside that boundary must be referred to a qualified person.

The degree of care, skill, and judgement that a reasonable and prudent technologist with similar training would exercise in comparable circumstances. It is the benchmark used to judge whether work was performed properly.

Having the education, training, experience, and current knowledge needed to perform a task safely and correctly without supervision. Competence is specific to a task, not a permanent personal trait.

Failure to exercise the standard of care that a reasonable technologist would provide, resulting in harm or loss. It generally requires a duty of care, a breach of that duty, causation, and actual damage.

The professional and often legal obligation to disclose unsafe conditions, serious errors, incompetence, or unprofessional conduct to the appropriate authority or employer, even when doing so is uncomfortable.

Reporting wrongdoing, danger, or misconduct, often outside the normal chain of command, when internal channels fail or when the public is at risk. Many jurisdictions protect good-faith whistleblowers from retaliation.

A situation where a personal, financial, or other interest could improperly influence professional judgement. It must be disclosed and managed, or the technologist must withdraw from the affected decision.

Consistently acting honestly and ethically, keeping commitments, refusing bribery, and not misrepresenting qualifications, data, or results. Integrity underpins public trust in the profession.

Protecting client, employer, and project information from unauthorized disclosure. Exceptions exist where disclosure is required by law, needed to prevent serious harm, or authorized by the owner.

Being answerable for one's own actions, decisions, and omissions, including admitting mistakes, correcting them, and accepting the consequences rather than shifting blame to others.

The welfare and safety of the general public, which takes priority over employer, client, or personal interests when the two conflict. It is the central justification for regulating technical professions.

A formal set of principles and rules adopted by a professional body that members must follow, covering honesty, competence, public safety, confidentiality, and fair dealing with colleagues and clients.

Behaviour that breaches the profession's ethical or competence standards, such as falsifying records, practising outside scope, or ignoring safety. It can lead to discipline, suspension, or loss of certification.

Ongoing learning, training, and reflective practice that keeps a technologist's knowledge and skills current as technology, codes, and standards change. Most certifying bodies require documented annual hours.

The practical use of scientific principles and methods to solve real-world technical problems, as distinct from pure research. It emphasizes measurable results, tested methods, and safe implementation.

Systematically breaking a problem into parts, gathering data, applying relevant theory and calculations, and forming defensible conclusions. Assumptions, methods, and limitations should be documented.

An iterative cycle of defining requirements, generating options, analysing and selecting a solution, prototyping, testing, and refining. Documentation and review at each stage reduce the risk of costly errors.

A structured, documented examination of a design by qualified reviewers against its requirements, safety, and standards. It catches errors early, before construction or manufacture makes changes expensive.

The quantified doubt about a measured value arising from instrument limits, environment, method, and operator. Results should be reported with an uncertainty so users can judge their reliability.

Comparing an instrument's output against a known reference standard and adjusting or documenting any deviation. Regular calibration establishes traceability and supports confidence in measurements.

An unbroken chain of documented comparisons linking a measurement back to a recognized national or international standard. It demonstrates that reported values are meaningful and comparable.

The permissible variation in a dimension, value, or performance characteristic. Designs must specify tolerances that are achievable, functional, and consistent with safety margins.

The ratio between a component's capacity and the expected load or demand, providing margin for uncertainty, wear, and overload. A larger factor gives more protection but may raise cost.

A standardized graphic representation of a component or system using views, dimensions, tolerances, and symbols. It must follow recognized conventions so any qualified reader interprets it identically.

A drawing revised after construction to record what was actually installed, including field changes. It supports future maintenance, renovation, and safety planning, and differs from the original design drawing.

A written document stating required materials, methods, performance, and quality standards for a project. Specifications and drawings together define the contract and must be read as a whole.

A formal, written authorization to alter scope, design, cost, or schedule after a contract is signed. Unrecorded changes create disputes, so all changes should be documented and approved.

Documented chronological record of who collected, handled, transferred, and stored a sample or item. It preserves evidential integrity and is essential for testing, disputes, and legal proceedings.

A contemporaneous written record of observations, measurements, conditions, and conversations made at a site. Notes should be dated, legible, and permanent, since they may later support reports or legal claims.

A structured document presenting purpose, methods, data, analysis, conclusions, and recommendations clearly for a defined audience. It should be accurate, traceable to evidence, and free of unsupported claims.

A short opening section of a report that states the purpose, key findings, and recommendations for decision-makers who may not read the full document. It must remain accurate and consistent with the body.

A structured process of identifying hazards, estimating the likelihood and severity of harm, and deciding on controls. Results should be documented and reviewed as conditions or designs change.

A ranked approach to reducing risk: eliminate the hazard, substitute something safer, use engineering controls, then administrative controls, and finally personal protective equipment. Higher levels generally protect more people more reliably.

Wearable equipment such as helmets, gloves, respirators, and eye protection that reduces exposure to hazards. It is the last line of defence and depends on correct selection, fit, training, and maintenance.

A procedure that isolates energy sources, applies locks and warning tags, and verifies zero energy before maintenance. It prevents unexpected startup or release of stored energy that could injure workers.

Any source of potential harm, such as energy, chemicals, noise, or unsafe conditions. A hazard is distinct from risk, which combines the likelihood and severity of harm from that hazard.

Meeting present needs without compromising the ability of future generations to meet theirs, applied through efficient resource use, reduced emissions and waste, durability, and life-cycle thinking in technical decisions.

A method of estimating environmental impacts of a product or project from raw material extraction through use and disposal. It supports comparing options and avoiding burden-shifting between stages.

The overarching purpose of professional regulation: ensuring that people affected by technical work are not harmed by incompetence, dishonesty, or unsafe practice. It justifies certification, standards, and discipline.
