A Task Safety Analysis (TSA) is a tool that focuses on job tasks as a way to identify hazards before they occur. Pre-task planning shall be performed for any activity or task that could reasonably present a risk of injury, illness, environmental or property damage.
The Task Safety Analysis procedure is the basic risk assessment tool for non-routine work. The TSA has proven to be a successful tool for use by craft, contractors and project workers performing non-routine tasks. The majority (>95%) of TSA's will be conducted by these groups. Routine work is risk assessed as part of the SOP development for a specific process or piece of equipment. Work not covered by an SOP should be risk assessed using a TSA or equivalent.
