AFSCI21-102 addresses ESOH hazards, prevention through design, engineering controls, workplace roles, feasibility studies, and engineering control project data calls. It requires the hierarchy of controls to be applied in a specified order and requires annual project data collection and reporting.

Applies to: It applies to the Air Force Sustainment Center.

Topics covered

  • Engineering hierarchy of controls
  • Occupational and environmental health hazards
  • Prevention through design
  • Feasibility studies
  • Engineering control project funding

Questions and answers

What order does AFSCI21-102 require for applying the hierarchy of controls?

Per DoDI 6055.01, DoD Safety and Occupational Health (SOH) Program, the order in which to apply hierarchy of controls is: elimination, substitution, engineering and/or administrative controls, and the appropriate use of Personal Protective Equipment (PPE) when other options fail to mitigate the hazard. (paragraph 1)

What must a workplace supervisor do with hazard controls?

Understands hierarchy of controls and ensures that hazard controls are implemented and functioning correctly. (paragraph 2)

What does Bioenvironmental Engineering do when requested?

Upon request, recommends and assists production engineer and workplace supervisor on ways to reduce ESOH hazards through implementation of PtD/HoC. (paragraph 2)

What must the Production Engineer address when handling occupational and environmental hazards?

When addressing occupational and environmental hazards, the Production Engineer shall address the engineering controls step in the hierarchy of controls and make elimination/substitution recommendations to the appropriate System Program Office (SPO) Engineering or SCM engineering authority on a commodity item, as delegated by the SPO. (paragraph 2)

How often does the engineering control projects data call occur?

A data call for engineering control projects will occur annually by AFSC/EN. (paragraph 1)
