Safety Information
Understanding 'Non-Sparking' Tools
The term 'non-sparking' is often considered misleading, as these tools can still generate 'cold sparks' under specific conditions. They are more accurately described as 'reduced-sparking tools.' While they provide essential protection in hazardous environments, they do not eliminate the risk entirely. Always assess your specific environment and consult with safety professionals or material manufacturers when working with highly flammable substances.
