What Is the Safe System of Guiding?

In 1999, a report from the US Institute of Medicine estimated that between 44,000 and 98,000 Americans died each year as a result of preventable medical errors. The finding was shocking — not because the errors happened, but because of why they happened.

The investigators found that most errors were not caused by incompetent or careless individuals. They were caused by systems that made it easy to make mistakes and hard to catch them. Tired doctors working impossible hours. Handwritten prescriptions that looked like other handwritten prescriptions. Information siloed between departments.

The response transformed healthcare. Not by trying to make individual clinicians less fallible — but by redesigning systems so that human error, when it occurred, was detected and contained before it became catastrophic.

This is the core insight of safe systems thinking: in high-risk environments, individual skill and care are necessary but not sufficient. The system around the individual must be designed to catch what the individual misses.

Why mountain guiding needs this now

Mountain guiding is a high-risk profession. Guides operate in dynamic, uncontrolled environments where conditions change rapidly and the consequences of mistakes can be fatal.

The industry has historically managed this risk through individual competence — rigorous certification programmes, apprenticeship models, and a culture of continuous learning. These are genuinely excellent. The ACMG, AMGA, IFMGA, and CAA certification pathways are among the most rigorous in any outdoor profession.

But competence is not a system. A well-trained, experienced guide can still make a poor decision under cognitive load, incomplete information, or time pressure. A guide company with excellent individual guides can still fail to communicate a critical client risk factor before a trip. A single point of failure — one person, one document, one communication — can result in an outcome that everyone in the organisation would have prevented if they’d had the information.

High-profile incidents in recent years have accelerated scrutiny of guide operations. Investigations increasingly look not just at the guide’s actions on the day, but at the systems behind those actions: the pre-trip risk assessment process, the client screening criteria, the documentation of decisions, the communication chain.

The question is no longer just was the guide qualified? It’s was the system designed to support good decisions?

What a safe system of guiding looks like

The Safe System of Work framework, developed primarily in road safety and construction, identifies five key elements:

Safer roads (environment): Designing the operating environment to reduce the likelihood of harmful events. For guiding: route selection criteria, weather decision protocols, turnaround time systems.

Safer speeds (pace and intensity): Managing the rate of operations to match the capacity of the system. For guiding: managing client-to-guide ratios, pacing progression relative to assessed client ability.

Safer vehicles (equipment and tools): Ensuring equipment is appropriate and maintained. For guiding: kit standards, communication equipment, emergency response capability.

Safer people (competence and wellbeing): Ensuring everyone in the system has the knowledge, skills, and capacity to perform their role safely. For guiding: guide certification, client screening, physical and psychological readiness assessment.

Post-incident response: Designing systems for reporting, learning, and improving after incidents occur. For guiding: incident logs, near-miss reporting, systematic review.

What’s critical about this framework is that it distributes responsibility. No single element is sufficient on its own. If the guide is highly competent but the client screening system is inadequate, the system as a whole is still unsafe.

What this means in practice

A guide company implementing a safe system of guiding would:

• Have a structured, documented pre-trip risk assessment process — not a mental checklist that lives in the guide’s head
• Screen clients against verified experience records, not self-reported skill levels
• Document weather and go/no-go decision criteria before a trip, not after
• Track guide certifications, hours, and physical condition across the team
• Maintain a confidential near-miss reporting system that creates learning without blame
• Be able to produce a coherent governance record if an incident triggers an investigation

None of this replaces guide skill and judgment. It creates the conditions in which that skill and judgment can operate most effectively — and it creates a documented record of due diligence that stands up under scrutiny.

How Ascents fits in

The consumer and aspiring guide product — available now at ascents.app — handles the individual documentation layer: verified logbooks, certification tracking, and goal management.

Ascents Pro is being built to operationalise the safe system of guiding at the company level. The goal is to make the governance work a natural byproduct of how trips are planned and run — not a separate compliance exercise on top of everything else.

Early access for guide companies is available now. Get in touch if you’d like to be part of building this.
