EMS 3D Printing & Maker Spaces 3

Question 1

An ISO 14001 auditor is reviewing water use in a maker space with post-processing operations. Which activity is most likely to generate contaminated wastewater requiring controls?

Accepted Answer

Washing resin prints with isopropyl alcohol (IPA)

Answer

IPA wash baths for resin prints accumulate dissolved photopolymer resin, creating hazardous solvent waste that cannot be poured down a drain.

Question 2

A maker space EMS has set an objective to reduce failed print waste by 20% in one year. Which leading indicator best measures progress toward this objective?

Accepted Answer

First-layer success rate tracked per printer per week

Answer

First-layer success rate is a leading indicator that predicts future waste generation, allowing corrective action before waste accumulates.

Question 3

When an EMS internal audit scope includes a maker space, which of the following external interested parties is most likely to have legally binding environmental obligations on the organization?

Accepted Answer

Local fire marshal and hazardous materials regulator

Answer

Fire marshals and hazmat regulators impose legally binding requirements for storage, handling, and disposal of flammable solvents and hazardous resins.

Question 4

A maker space stores five gallons of IPA solvent for resin cleaning. Under an EMS, this storage situation requires evaluation against:

Accepted Answer

Local fire codes, EPA solvent regulations, and the EMS spill emergency response procedure

Answer

Flammable solvent storage triggers fire code compliance, EPA waste regulations, and must be covered by the EMS emergency preparedness procedure.

Question 5

Which document would an EMS auditor request to verify that maker space staff are competent to handle photopolymer resins safely?

Accepted Answer

Training records and Safety Data Sheet (SDS) review acknowledgments

Answer

ISO 14001 Clause 7.2 requires documented evidence of competence for personnel performing tasks with significant environmental aspects, including SDS comprehension.
