Emergency Overview

Solid. Silvery. Odorless. Non-combustible as supplied. Small chips, fine turnings and dust from processing may

be readily ignitable.

Explosion/fire hazards may be present when (See Sections 5, 7 and 10 for additional information):

* Dust or fines are dispersed in the air.

* Chips, dust or fines are in contact with water.

* Dust or fines are in contact with certain metal oxides (e.g. rust).

* Molten metal is in contact with water/moisture or certain metal oxides.

Dust and fume from processing can cause irritation of eyes, skin and upper respiratory tract; metal fume fever and

lung disease.

Material Safety Data Sheet Product Name: WROUGHT ALUMINUM PRODUCTS, 5xxx SERIES ALLOYS ID: 667 Fire/Explosion May be a potential hazard under the following conditions: * Dust or fines dispersed in the air can be explosive. Even a minor dust cloud can explode violently. * Chips, dust or fines in contact with water can generate flammable/explosive hydrogen gas. Hydrogen gas could present an explosion hazard in confined or poorly ventilated spaces. * Dust or fines in contact with certain metal oxides (e.g.

Material Safety Data Sheet Product Name: WROUGHT ALUMINUM PRODUCTS, 5xxx SERIES ALLOYS ID: 667 Drops of molten metal in water (e.g. from plasma arc cutting), while not normally an explosion hazard, can generate enough flammable hydrogen gas to present an explosion hazard. Vigorous circulation of the water and removal of the particles minimize the hazards.
