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 ) .
