Intrinsically Safe Hose Continuity Tester
Hoses play an important role in hazardous area operations and owing to their direct interaction with moving liquids and powders can be at risk of becoming electrostatically charged. At no point in its structure should the metal components of a hose be permitted to accumulate static electricity.
Examples of metal components that have the potential to accumulate static charge are couplings and metal wire helixes.
Periodic resistance testing of hoses with meters by a responsible person (experienced electrician) helps identify potentially faulty hoses so that they can be removed from service.
Another option is to supply drivers with an easy to use hose continuity tester that provides an LED indicator to indicate a PASS or FAIL test of the hose. It should be emphasised that drivers must be suitably trained as being competent to use such testers.
