How to Calculate Dart Rate Osha

OSHA DART Rate Calculator

The OSHA DART (Days Away, Restricted, or Transferred) rate is a key metric used to measure a company's safety performance. It indicates the number of OSHA-recordable injuries and illnesses that result in days away from work, restricted work, or transfer to another job per 100 full-time workers during a calendar year. A lower DART rate generally signifies a safer workplace.

Your DART Rate:

function calculateDART() { var totalHoursWorked = parseFloat(document.getElementById("totalHoursWorked").value); var recordableIncidents = parseFloat(document.getElementById("recordableIncidents").value); var dartRateResultElement = document.getElementById("dartRateResult"); // Clear previous results dartRateResultElement.textContent = ""; // Validate inputs if (isNaN(totalHoursWorked) || isNaN(recordableIncidents) || totalHoursWorked <= 0) { dartRateResultElement.textContent = "Please enter valid positive numbers for all fields."; return; } // OSHA DART Rate Formula: (Number of Recordable Incidents * 200,000) / Total Hours Worked // The 200,000 factor is based on 100 employees working 40 hours per week for 50 weeks per year (100 * 40 * 50 = 200,000). var dartRate = (recordableIncidents * 200000) / totalHoursWorked; dartRateResultElement.textContent = dartRate.toFixed(2); } .calculator-container { font-family: sans-serif; border: 1px solid #ccc; padding: 20px; border-radius: 8px; max-width: 600px; margin: 20px auto; background-color: #f9f9f9; } .calculator-container h2, .calculator-container h3 { text-align: center; color: #333; } .input-section { margin-bottom: 20px; } .input-section label { display: block; margin-bottom: 8px; font-weight: bold; color: #555; } .input-section input[type="number"] { width: calc(100% – 22px); padding: 10px; margin-bottom: 15px; border: 1px solid #ccc; border-radius: 4px; box-sizing: border-box; } .calculator-container button { display: block; width: 100%; padding: 12px 20px; background-color: #007bff; color: white; border: none; border-radius: 4px; font-size: 16px; cursor: pointer; transition: background-color 0.3s ease; } .calculator-container button:hover { background-color: #0056b3; } #result { margin-top: 25px; padding: 15px; background-color: #e9ecef; border-radius: 4px; text-align: center; } #result h3 { margin-top: 0; color: #333; } #dartRateResult { font-size: 24px; font-weight: bold; color: #28a745; }
