3D Printing & Maker Spaces Flashcards

A community maker space is open to the public, including minors. Under ISO 14001, this context most directly affects which element of the EMS?

Answer: Scope definition, interested party analysis, and chemical handling operational controls

Public access including minors expands the interested party landscape and tightens chemical storage and ventilation operational controls to protect vulnerable populations.

During a maker space audit, the auditor notices that environmental objectives are posted but no targets or timelines are assigned. This indicates a gap in compliance with:

Answer: ISO 14001 Clause 6.2 – Environmental objectives and planning to achieve them

Clause 6.2 requires that objectives be measurable where practicable and include timelines, responsible parties, and how achievement will be evaluated.

A maker space uses metal-sintering (SLS) 3D printing with aluminum powder. The primary EMS concern unique to metal powder processes is:

Answer: Combustible dust explosion risk and fine metal particle air emissions

Fine metal powders are combustible and can create explosive atmospheres, making dust collection, grounding, and explosion prevention critical EMS operational controls.

An EMS internal audit reveals that a maker space tracks energy use monthly but has never benchmarked against an industry standard or prior baseline. The most appropriate audit finding is:

Answer: Opportunity for improvement — monitoring data is being collected but not used to drive objectives

Collecting data without using it to set baselines or drive improvement is a missed opportunity; ISO 14001 Clause 9.1 intends that monitoring data inform objectives and corrective action.

Which waste stream from a maker space would most likely require a manifest and licensed hazardous waste transporter for off-site disposal in the US?

Answer: Spent photopolymer resin wash solvent exceeding generator thresholds

Spent IPA contaminated with photopolymer resin is a listed or characteristic hazardous waste under RCRA, requiring a manifest and licensed transporter once generator thresholds are exceeded.

A maker space EMS audit finds that corrective actions from the previous audit cycle were documented but never verified for effectiveness. This violates which ISO 14001 clause?

Answer: Clause 10.2 – Nonconformity and corrective action, specifically the effectiveness review requirement

Clause 10.2 explicitly requires organizations to review the effectiveness of corrective actions taken, not merely document that actions were completed.

When assessing a maker space's environmental aspect register, an auditor should verify that the evaluation considers which combination of factors per ISO 14001 Annex A guidance?

Answer: Scale of impact, severity, probability of occurrence, and whether the aspect is under the organization's control

ISO 14001 Annex A.6.1.2 guides organizations to consider scale, severity, duration, probability, and control when evaluating the significance of environmental aspects.
