About Survival Nexus

Building a careful, accessible learning path around emergency response and community readiness.

Why I Built This

I’m Alexander Gordon Petitjean, a designer and maker with experience in hands-on construction and AI-assisted prototyping. I’m also a double below-knee amputee, so questions about mobility, weight, reliability, and accessibility are part of everyday life for me—not abstract design exercises.

I am not an EMT, firefighter, medical director, fire-service instructor, or survival expert. Survival Nexus is an independent learning and design project: a place to organize research, explore emergency readiness, document experiments, and make complicated information easier to navigate.

The main learning path now centers on EMS fundamentals, fire and wildfire safety, rescue awareness, responder readiness, and accessible equipment systems. Earlier outdoor, travel, firecraft, and recovery material remains in a separate archive. When qualified training, medical direction, department policy, or professional care is required, this site should point toward it—not pretend to replace it.

What I Bring to the Work

Builder’s Perspective

I approach problems by breaking them into parts, comparing trade-offs, making prototypes, and revising what does not work. That mindset shapes the guides and tools on this site.

Adaptive Perspective

My lived experience with prosthetics makes accessibility central to the project. I pay particular attention to load, balance, fatigue, reach, dexterity, and whether instructions account for bodies that work differently.

How I Work

Research Before Claims

  • Start with the use case: what problem is being solved and what could fail?
  • Consult reliable sources: favor recognized agencies, training organizations, manufacturers’ documentation, and qualified practitioners.
  • Separate evidence from opinion: clearly distinguish sourced guidance, personal observations, and ideas that still need testing.
  • Document direct tests: describe the setup and limitations instead of implying broader experience.
  • Correct mistakes: update material when better evidence or experienced feedback becomes available.

What “Tested” Means Here

If I have personally used or tested something, I will say how. If a conclusion comes from research, specifications, or another source, I will identify that too. Products are not presented as field-proven by me unless I can document that experience.

Disclosure & Ethics

Recommendations may be based on direct use, documented specifications, reputable sources, or comparisons with similar equipment. Each review should make that basis clear.
