01 / ASSESS
Start with the obvious.
Calculate the rest.
The SCL method uses recognized icons first. If an icon applies, high energy is present. When no icon applies, estimate the physical energy.
STEP 1 · RECOGNIZED CONDITIONS
Does an icon apply?
Select every high-energy condition present. Each recognized icon is sufficient to answer “Yes” to high energy.
No icon selected yet
If none applies, use a calculation below.

HIGH ENERGY
This estimate exceeds the SCL screening threshold.
iScreening estimate only. Use qualified exposure assessment for chemical and radiation hazards. Electrical calculations use the SCL model’s 1,500 Ω body-resistance assumption; pressure and mechanical calculations remain simplified physical estimates.
02 / CLASSIFY
Four questions.
One learning path.
Answer with the best verified facts available. The route updates immediately and shows the SCL classification and learning priority.
01
Was high energy present?
More than 1,500 J of physical energy or a recognized high-energy hazard.
02
Did a high-energy incident occur?
Energy was released and a worker contacted it or was within proximity—within 6 ft (1.8 m) of the high-energy source.
03
Was a direct control present?
Targeted, effective when properly used, and resilient to unrelated unintentional error.
04
Was a serious injury sustained?
A life-threatening, life-altering injury, or fatality.

MODEL PRINCIPLES
Classification is the start
of learning—not the finish.
Energy is objective
Physical magnitude creates a consistent starting point across tasks and organizations.
Controls create capacity
A direct control targets the source and remains effective despite unrelated unintentional error.
Outcomes guide attention
Classification helps teams prioritize learning; it is not a scorecard for blame.

IMPORTANT USE NOTICE
Verify every result with a qualified professional.
This tool provides educational screening estimates and automated, rules-based classifications from the information entered by the user. Results may be incomplete, inaccurate, or inappropriate for a particular workplace, task, jurisdiction, or set of conditions. Any AI-assisted or automatically generated content must be independently reviewed and must not replace professional judgment.
The tool is not engineering, legal, medical, industrial-hygiene, or occupational-safety advice. Before making a decision, verify all inputs, calculations, classifications, controls, and conclusions with a competent safety professional or other appropriately qualified specialist and consult applicable laws, standards, procedures, and manufacturer guidance.
Do not use this tool for emergency response or as the sole basis to start, continue, suspend, or approve work. The user and their organization remain responsible for hazard assessment, controls, regulatory compliance, and all actions taken.
