The Definition of Trigger Point
A trigger point is a predefined condition or threshold that initiates a specific safety response or action.
A trigger point is a predefined condition or threshold that initiates a specific safety response or action.
A predetermined condition, measurement, or event that, once reached, automatically initiates a specific safety response — such as evacuation, work stoppage, or escalated monitoring — removing ambiguity about when action is required.
A facility sets a trigger point for heat stress monitoring: once the heat index reaches a defined level, supervisors must implement mandatory rest breaks and increase water availability for outdoor crews.
Trigger points remove subjective judgment calls in the moment by establishing clear, predefined thresholds in advance, helping ensure a consistent and timely response to developing hazards.
Common examples include gas detector alarm thresholds, weather conditions like lightning proximity or wind speed, and exposure monitoring results that exceed a defined action level.
Trigger points are typically established by safety professionals based on regulatory requirements, manufacturer guidance, and risk assessments specific to the hazards present at a given site.
