TTD

TTD, or Time to Dangerous, is a safety measure used in workplaces to assess how quickly a person could be exposed to a hazardous situation that could cause serious injury or harm. It estimates the time it would take for a worker to reach a dangerous area or condition if they moved without protection or intervention. Understanding TTD helps safety teams design effective controls and ensure workers can evacuate or stay safe within critical timeframes, reducing the risk of accidents and protecting health.
