Un ambiente peligroso, como es define con respecto a una atmósfera combustible, es uno que podría quemar explosivamente con la adición de energía suficiente para causar la ignición. Los ambientes peligrosos son divididos en categorías por el Código Eléctrico Nacional para definir las condiciones que puede causar la ignición de la atmósfera combustible. Estas categorías incluyen gases combustibles y polvo suspendido y la partícula. El equipo puede ser evaluado y puede ser certificado como Intrínsecamente seguro para la operación en varios ambientes peligrosos.

Algunas aplicaciones de monitoreo de vibración requieren de un transductor para ser instalado en un ambiente peligroso. En estas aplicaciones, el transductor debe poder no encender la atmósfera circundante. Un transductor que es intrínsecamente seguro no puede desarrollar suficiente energía para – ni por energía de calor, ni por energía de chispa – encender el ambiente peligroso, ya sea operando normalmente o bajo condiciones de falla. Un transductor aprobado como Intrínsecamente Seguro puede ser instalado directamente en el ambiente peligroso.
