Is it mandatory to display pictograms on machines and systems? Must they also be displayed on electrical panels? What are the requirements in this instance? OSHA, ANSI, UL, CSA; what are the applicable standards?<\/strong><\/p>\n

In an industrial system, on board a machine or in an electrical panel there are hazards to which operators tasked with equipment maintenance and operation are exposed. In Europe and the US, Government bodies dealing with safety on the workplace impose that operators be suitably protected from those hazards, suitably trained and informed. Even when safety and protection barriers are provided to reduce the hazards to which operators are exposed, there are still some residual risks\u2026 It is precisely for those residual risks that Government bodies and relevant regulations impose the use of safety pictograms, the so-called safety labels.<\/p>\n

OSHA Occupational Safety and Health Administration the American Government Body dealing with safety on the workplace, with 1910.145, prescribes requirements to signal residual risks in direct reference to standard ANSI Z535 \u201cProduct Safety Signs and Labels\u201d as the reference document for the use and application of safety labels, which therefore becomes a legislative rule. The need for safety labels does not depend on the place on which they are applied, they depend on residual risk and therefore the hazard to which the operator may be exposed regardless of where the hazard may appear; this means that pictograms may be applied on protection fences, on mechanical part guards, on cabinet doors but also within electrical panels.<\/p>\n

Since the beginning Tekima has produced safety labels in compliance with standard ANSI Z535 and certified under UL 969, also for special applications or as designed by the customer. The already broad range of safety labels required by applicative rules NFPA 70 (NEC), NFPA 79 and C22.1 (CE Code) include those for electrical panels, specifically produced according to US and Canadian standards UL 508a and C22.2 No. 286.<\/p>\n

The advantages of UL 508a and C22.2 No. 286 labels:<\/p>\n
