regulations, see Petzl.com

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).
