Non sparking tools as per ISGOTT 6th Edition
Non sparking tools have always found a special mention in each edition of ISGOTT. The ISGOTT 6th edition is no different, but something has changed this time. Let take a look.
Maritime vessels operate in some of the most hazardous environments on Earth. They are constantly exposed to the elements, and they often carry volatile cargoes. This means that there is always a risk of fire or explosion.
Non sparking tools are essential for maritime safety because they help to reduce the risk of fire and explosion. Non-sparking tools are made from materials that are less likely to produce sparks when struck or rubbed against another object. This makes them ideal for use in hazardous areas, such as cargo tanks and pump rooms.

As per ISGOTT 6th Edition, the use of hand tools such as chipping hammers and scrapers for steel preparation and maintenance may be permitted without a Hot Work Permit. Their use must however be restricted to deck areas and fittings not connected to the cargo system. The work area should be gas free and clear of combustible materials. The ship must not be engaged in any cargo bunker, ballasting, tank cleaning, gas freeing, purging or inerting operations.
Non-ferrous, so called non-sparking, tools are only marginally less likely to give rise to an incendive spark, and, because of their comparative softness, are not as efficient as their ferrous equivalents. Particles of concrete, sand or other rock-like substances are likely to become embedded in the working face or edge of such tools, and can then cause incendive sparks on impact with ferrous or other hard metals. The use of non-ferrous tools is therefore not recommended.
