What is DART Rate? The DART Rate stands for Days Away, Restricted, or Transferred Rate, and is a workplace safety metric used to track more serious recordable incidents—those that result in time off work, restricted duty, or job transfer. This rate helps employers monitor not just how often incidents occur, but how significantly they affect … Read more

What is Near Miss Frequency Rate (NMFR)? The Near Miss Frequency Rate (NMFR) is a proactive safety metric used to measure how often near-miss incidents occur in the workplace. A near miss is an unplanned event that didn’t result in injury, illness, or damage—but had the potential to do so. Calculating NMFR helps organizations identify … Read more

What is a Radiation Dose? A radiation dose measures the amount of ionizing radiation energy absorbed by the body or an object. It’s a critical metric in fields like nuclear medicine, radiology, radiological protection, and health physics to ensure safety and minimize exposure risks. The Radiation Dose Calculator helps estimate absorbed, equivalent, and effective doses … Read more

What is Risk Priority Number (RPN)? The Risk Priority Number (RPN) is a key metric used in Failure Mode and Effects Analysis (FMEA) to evaluate and prioritize potential risks in a process, product, or system. It helps identify which failure modes need immediate attention by quantifying risk based on three factors: Each factor is rated … Read more

What is Ergonomic Risk? Ergonomic risk refers to the potential for injuries or disorders caused by poor design of workstations, tools, or tasks that require repetitive motion, awkward posture, or excessive force. These risks can lead to Musculoskeletal Disorders (MSDs) such as carpal tunnel syndrome, back pain, or tendonitis. The Ergonomic Risk Calculator helps assess … Read more

What is Accident Frequency Rate (AFR)? The Accident Frequency Rate (AFR) is a widely used safety metric that measures how frequently workplace accidents occur over a set number of working hours. Unlike general injury counts, AFR provides a standardized indicator that helps organizations monitor safety performance and compare it across departments, sites, or industries. AFR … Read more

What is Noise Exposure? Noise exposure refers to the amount of sound energy a person is subjected to during a workday. Prolonged or excessive exposure to high noise levels can lead to noise-induced hearing loss (NIHL) and other health risks such as stress, fatigue, and reduced productivity. The Noise Exposure Calculator helps determine whether an … Read more

What is the Total Recordable Injury Frequency Rate (TRIFR)? Total Recordable Injury Frequency Rate (TRIFR) is a key safety performance indicator used to measure the rate of workplace injuries and illnesses that are severe enough to be recorded according to occupational health and safety regulations. It helps organizations monitor safety performance and benchmark against industry … Read more

What is LTIFR? LTIFR (Lost-Time Injury Frequency Rate) is a standard safety metric used in occupational health and safety to measure the number of lost-time injuries per 1 million hours worked. It helps evaluate the effectiveness of an organization’s safety practices and compare performance across industries and sites. LTIFR Formula The formula for calculating LTIFR … Read more
