Combined fit
Interfaces such as helmet, hearing protection and respirator fit remain compatible.
STATIC Protective Ensemble Graph
Compatibility relationships among protective products worn or used together.
INSIDE STATIC PROTECTIVE ENSEMBLE GRAPH
Purpose, systems, and connections.
Protective Ensemble Graph examines the combined equipment rather than judging each piece alone. Seals, overlaps, attachment and configuration determine whether parts preserve their intended protection in an ensemble.
Layer interaction
One protective layer must not compromise another’s approved use.
Approved configuration
The combination remains connected to the relevant tests and limitations.
How it connects
Separate product ratings do not automatically prove that an arbitrary combination preserves those ratings.
