Protect the worker
Hours, child labour, sanitation, guarding and inspection.

Safety was built in response to work that could no longer be ignored.
Industrial growth created new energy, scale and speed. Workers, reformers, engineers, investigators and regulators responded with rules, guards, training, management systems and, eventually, a sharper focus on the controls that prevent death and permanent harm.
Explore the timelineThe central shift
Safety did not move in one straight line.
Each era added useful tools, but it also left blind spots. Prescriptive rules protected workers from visible machinery. Behavioural models drew attention to repeated events. Major disasters exposed design, governance and regulatory failures. Current practice brings these lessons together around material risk and control reliability.
Prevent the accident
Training, supervision, standard work and event ratios.
Control the system
Risk assessment, management systems and process safety.
Prevent serious harm
Critical controls, high-potential events, SIF and FPI prevention.
From your treasure chest
Safety instruction from an earlier industrial era
A supplied archival training manual describes a supervisor-led course built around demonstrations, safety problem sheets, job breakdowns, hazard spotting, practice drills and assigned responsibilities. That is recognizably modern in one respect: safety has to be translated into the job, not left as a policy.
Its limits are equally instructive. The material reflects an era centred on instruction, supervision and individual job performance. Modern HSE adds stronger attention to design, organizational conditions, worker participation, occupational health, major-accident hazards and control assurance.
Image and dating noteThe image is an original HSE Hub illustration, not a reproduction of the source manual. The scan metadata says 2006, but that is the scan date, not proof of publication. The timeline therefore treats the source as an undated archival document.
Interactive history
What changed, and what changed because of it.
Use the whole history
Old models are tools, not laws of nature.
Safety practice becomes weaker when one model is asked to explain every type of harm.
Heinrich triangle
Useful for encouraging reporting and learning before injury. Weak when a fixed ratio is treated as universal or minor-injury reduction is assumed to prevent every fatality.
Management systems
Useful for defining responsibilities and repeatable processes. Weak when documents and audit scores are mistaken for field control effectiveness.
SIF and critical controls
Useful for fatal-risk pathways, high-potential events and barrier health. Weak if occupational disease, wellbeing or everyday injuries disappear from attention.
Editorial note
History is contested evidence.
This timeline uses official and primary sources where practical. Corporate histories are labelled as such. Fatality totals and causal interpretations can change across inquiries and later research. The page avoids treating any event as having one simple cause.
