The PIXA Z0 was designed to meet the needs of maintenance
and industrial professionals working in potentially explosive
environments. It has the following certifications: ATEX area 0
(II 1 G Ex ia IIC T4), HAZLOC (Class I Div 1 A, B, C, D T4),
and IECEx (Gas: Ex ia IIC T4 Ga). Durable, waterproof,
and resistant to certain chemicals, it is ideal for intensive
and demanding professional use.
If an explosion hazard is identified in an environment, the hazardous areas are classified as areas at risk, depending on the prevalence
and type of combustible, gas or dust. All of the materials used in these zones must conform with current regulations for this type of zone
(ATEX and/or HAZLOC).
