The Capacity Model

We are changing the way we do safety.

We are in the people business and we know that people are fallible. We always choose prevention, but we realize that mistakes will happen. The question becomes do we have the capacity to absorb failure without causing harm. To be ready, we will plan and execute work assuming that failure could happen at any moment. We will learn from each job, each mistake and success – to continue getting better in every aspect. Safety is not the complete absence of injuries – it is the presence of capacity. Safety is not just a policy – safety is the core of who we are and always at the forefront of our focus.

Quanta Human Performance Principles

1. People Make Mistakes

Error is normal. Even the best people make mistakes.

2. Failure Can Occur Safely

It’s not if, it’s when. We will always plan and execute our work as if failure is going to happen today.

3. Context Influences Behavior

Workers do what they do for a reason, and the reason makes sense to the workers given the context of the situation.

4. Violations are Rarely, if Ever, Malicious

Blame fixes nothing.

5. Incidents Can Stem From Normal Deviations

How we imagine work takes place is different from how work actually takes place.

6. Management's Response to Failure Matters

Managers shape how the organization learns by the their reaction to failure.

7. Learning is a Deliberate Improvement Strategy

Learning is a strategic and operational choice towards improvement

The Capacity Model

The Capacity Model creates a work environment that focuses on preventing an incident while also building the capacity for failure by always planning and executing our work as if failure is going to happen today.

Establishing a learning-based philosophy allows the organization to adapt and mature, building upon lessons learned and operational efficiences identified through collaboration.

The SHEQ Shift

Foundational Assumption

Significant events are a result of a release or transfer of energy that can’t be absorbed safely.

Define The Problem (why)

Life-ending, life-threatening, and life-changing events still occur in our industries.

Define Success (what)

Life-ending, life-threatening, and life-changing events are eliminated.

Guiding Principle (how)

When high energy exposure exists we must have capacity to fail safely.

The Energy Wheel

The Energy Wheel is a hazard-identification tool that helps workers systematically look for types of energy. The Energy Wheel focuses on hazards that can cause a life-threatening, life-altering, or life-ending injury.

STKY Discussions

It’s important for crews to start focusing on STKY scenarios that could occur on their jobsite. Significant events are a result of a release or transfer of energy that can’t be absorbed safely. When high-energy exposure exists, we must have capacity to fail safely.

STKY discussions are brief talks that focus on identifying STKY and deciding how to deal with it. These should be part of normal job briefings but can be repeated throughout the day.

  1.  What’s STKY on this job site?
  2.  When a STKY event happens, what will protect you and the crew?
  3.  Is that protection enough, or do you need more? What else can you do to protect against STKY?

STKYa – an actual injury that results in one of the three outcomes:

1. Life-threatening

A state where death is imminent or probable if not immediately addressed by trained medical personnel, often with the aid of life-sustaining support. Examples include profuse bleeding, damaged/blocked airway, untreated shock, or unnatural arrhythmia (irregular heartbeat due to unnatural causes like a shock or ingestion of a toxic substance).

2. Life-altering

A state of permanent or long-term impairment or loss of the use of an internal organ, bodily function, or body part. Example injuries include amputations, loss of vision/eye, compound fractures, spinal injuries or paralysis, severe burns, and disfigurement.

3. Life-ending

An injury that results in the death of an employee.
