The type of incidents which may occur and the level of molten metal to which workers may be exposed to can be broken down as follows:
BS EN ISO 11612 is the standard which clothes will usually be tested to. It places fabric into three performance levels which are considered to relate to Levels 1, 2 and 3 above. Those performance levels are in the two tables below.
Note that the performance levels stated are those in ‘test’ conditions. The amount of molten metal splash in a real incident will vary. This should be considered as part of your assessment.
(generally also acceptable for molten aluminium bronze and molten minerals)
|Performance levels||Molten aluminium splash (g)|
(generally also acceptable for molten steel, molten copper and molten brass)
|Performance levels||Molten iron splash (g)|
