The safety triangle, also known as the Heinrich Triangle, is a principle of industrial safety measures. It indicates the association between major injuries, minor accidents, and near-misses and implies that if the number of minor accidents is decreased, there would be a subsequent decrease in the number of deadly injuries. The triangle was originally formulated by Herbert William Heinrich in 1931 and has since been revised and extended to others. It is also seen visually as a triangle or pyramid and has been described as the pillar of the theory of occupational health and safety of the 20th century.
The safety triangle indicates the association with the number of injuries that end in major injury, minor injury, or no injury. Heinrich was a pioneer in the area of occupational health and safety. He served as an Assistant Superintendent for an insurance corporation and tried to lower the amount of significant industrial injuries. He started a review of more than 75.000 injury reports from the insurance company’s archives as well as the documents kept by individual manufacturing sites. From this evidence, he indicated the relationship between one serious injury accident and 29 minor injuries, and 300 non-injury accidents.
He concluded that, by lowering the number of minor injuries, manufacturing businesses would see a resulting reduction in the number of major accidents. The following: The partnership is also pictorially shown in the shape of a triangle or pyramid. The safety triangle or safety pyramid has been widely used in occupational health and safety systems for the next 80 years and has been described as a pillar of the theory of health and safety. Heinrich’s argument also indicated that 88 per cent of all injuries were triggered by a human decision to execute a dangerous act.
Components of Safety Triangle:
The safety triangle consists of five sections. As the triangle rises, each part suggests a further unsafe act or occurrence. Details are given below on all aspects of the safety triangle and starting with the most serious consequences.
Fatality: Fatality is the most critical aspect of the safety triangle. It demonstrates the occurrence of death by accident.
Lost Time & Severe Injury: The definition for workplace injury covers both disabled job accidents and non-disabled work injuries. These accidents may include,
- Eyes damages requiring care by a doctor
- Broken bones
- Hospital injuries
- Accidents requiring treatment by a health care professional
- Illnesses requiring limitation of mobility and operation.
Minor injuries Any injury suffered that does not fulfil all of the criteria of the serious injury alluded to above. For instance, wound that can be treated immediately on-site, like cuts, small wounds, or scratches.
Near Misses An incident in which an injury or a disruption of service may have been plausible if the conditions had been somewhat different.
Unsafe Acts: Any act that differs from a commonly accepted safe way or a defined form of doing a task and raises the probability of an injury.
How to Implement Safety Pyramid:
To access safety procedures at any office, establish a written health and safety policy addressing the above-noted key points. Maintain it with other safety records on activities, machinery, and products. Discuss the curriculum with others throughout implementation to ensure their safety needs are addressed. Incorporate a risk recognition, risk management, and risk control system.
Ensure that staff and others are familiar with the safety policy, safety practices, and existing legal protections and health standards. Other components include providing safety documents, induction for new hires, safety instruction for new protocols, special precautions for unskilled employees, and maintaining track of accidents, near misses, and possible hazards. OSHA Outreach Courses specialize in occupational safety and health certifications and have an extensive library of on-demand online training.
