What are the most common industrial safety metrics and how are they calculated?

Lost Time Injury Frequency Rate (LTIFR)- LTIFR is calculated by dividing the total number of lost time injuries in a given period by the total number of hours worked during that period, then multiplied by 1,000,000. Total Recordable Injury Rate (TRIR)-TRIR is calculated by dividing the total number of recordable injuries in a given period by the total number of hours worked during that period, then multiplied by 200,000.

In my experience, these industrial safety metrics play a crucial role in assessing and improving workplace safety. Incident rate, lost time injury frequency rate, lost time injury severity rate, total recordable injury rate, near miss frequency rate, and safety audit score provide valuable insights into the effectiveness of safety programs and practices. By accurately calculating and analyzing these metrics, organizations can identify areas for improvement, implement targeted safety measures, and ultimately create safer work environments for their employees.

Para calcular a Taxa de Frequência de Acidentes com Afastamento (LTIFR), siga a fórmula: LTIFR= Numero de Acidentes com Afastamento×1,000,000 ? Numero Total de Horas Trabalhadas por Todos os Funcionarios . Essa fórmula fornecerá a taxa de acidentes com afastamento por milh?o de horas trabalhadas em um determinado período. Certifique-se de ter informa??es precisas sobre o número de acidentes com afastamento e o total de horas trabalhadas para realizar o cálculo.

The total recordable incident rate (TRIR) is a measure of occupational safety and health, useful for comparing working conditions in workplaces and industries. It is calculated by combining the actual number of safety incidents and total work hours of all employees with a standard employee group (100 employees working 40 hours a week for 50 weeks a year)

Para calcular a Taxa de Gravidade de Acidentes com Afastamento (LTISR), utilize a seguinte fórmula: Numero Total de Horas Trabalhadas por Todos os Funcionarios LTISR= Numero Total de Dias Perdidos devido a Acidentes de Trabalho×1,000,000 ? Numero Total de Horas Trabalhadas por Todos os Funcionarios Essa fórmula fornecerá a taxa de horas trabalhadas em um determinado período. Certifique-se de ter informa??es precisas sobre o número total de dias perdidos e o total de horas trabalhadas para realizar o cálculo. Essa taxa é uma medida da gravidade dos acidentes em termos do impacto no tempo de trabalho perdido.

In a facility working at heights, TRIFF Rate was implemented. Obstacles like inadequate training, insufficient safety equipment, and inconsistent protocols were addressed. Safety training improved, proper equipment was provided, and safety protocols were established. Incidents reduced, safety awareness increased, compliance improved, reputation enhanced, and costs saved.

NMFR is one of the vital safety matrices to be calculated. In my industry, we are doing that NMFR as well as incident investigation from HSE experts. This safety matrix helps to visualize the trend of near misses and helps to take important decisions to eliminate or substitute the hazards related to the incident. This NMFR helps to take a proactive approach from the management, that helps contribute to the overall goal of HSE: which is no injury, no illnesses.

calcular a Taxa de Frequência de Near Miss (NMFR), utilize a seguinte fórmula: Numero Total de Horas Trabalhadas por Todos os Funcionarios NMFR= Numero de Near Misses×1,000,000 ? Numero Total de Horas Trabalhadas por Todos os Funcionarios Essa fórmula fornecerá a taxa de near misses por milh?o de horas trabalhadas em um determinado período. Os near misses s?o eventos críticos que poderiam ter resultado em les?es ou danos, e a NMFR é uma métrica valiosa para identificar áreas de risco potencial. Certifique-se de ter informa??es precisas sobre o número de near misses e o total de horas trabalhadas para realizar o cálculo.

calcular a Pontua??o de Auditoria de Seguran?a, utilize a seguinte fórmula: Pontuacao de Auditoria de Seguranca= Numero de Itens em Conformidade ? Numero Total de Itens Auditados ×100 Essa fórmula fornecerá a pontua??o de conformidade em termos percentuais com as normas, políticas e procedimentos de seguran?a estabelecidos. Certifique-se de ter informa??es precisas sobre o número de itens em conformidade e o total de itens auditados para realizar o cálculo. A pontua??o de auditoria de seguran?a é uma métrica valiosa para avaliar e melhorar continuamente o desempenho em seguran?a organizacional.

Therefore, the Occupational Safety audit defines a structured process for collecting information about the efficiency and reliability of the Occupational Health and Safety management system. It is an important instrument for the organization to self-evaluate and support the preparation of the action plan, with a view to adapting the identified non-conformities.

Given root cause investigations often identify HSE culture as the drive behind human behavioural Incidents I'd consider a measure of HSE Culture such as the Parker Hudson model or even a basic measurement of perception based on the Bradley curve as relevant.

Industrial safety metrics are crucial for assessing and improving workplaces. As example:- 1. Lost time injury frequency rate 2. Total recordable injury frequency rate 3. Near-miss rate 4. Safety training metrics 5. Safety compliance rate These metrics help organizations track and improve the safety performance.

Is the industry still using ltir & trif rates instead of proactive measurement? If so it hasn’t moved in 30 years. Proactive measures and audits will tell you more than manipulated incident stats.

The 4 main objectives of occupational safety are to prevent occupational accidents and illnesses, promote the occupational health of employees and ensure compliance with established standards and regulations.

Industrial safety metrics like incident rate, LTIFR, TRIR, NMFR, and safety audit score are essential for evaluating and improving workplace safety. Calculated based on standardized formulas, these metrics provide valuable insights into safety performance and areas for improvement. By accurately assessing these metrics, organizations can proactively identify hazards, implement targeted safety measures, and cultivate a culture of safety.
