2.11 Chemical Hazards
This section provides information on chemical hazards that can be present
in products.
2.11.1 Beryllium Oxide Hazard
This section provides information on Beryllium Oxide (BeO). BeO is a restricted
substance that is contained in certain components in some Ericsson products.
If a product contains BeO, this is clearly marked on the unit containing BeO.

Figure 12 BeO Hazard Symbol
Note: This information only applies to products marked with the BeO symbol.
Danger!
This product contains Beryllium Oxide (BeO), which can cause injury to skin
or mucous membranes severe enough to endanger life or cause permanent
injury. BeO dust is created by chafing, filing, or breakage and is extremely
dangerous if inhaled, even for only a few seconds. Particles penetrating the
skin through wounds or abrasions are liable to cause chronic ulcerations. Do
not handle components containing BeO without protection.
Symptoms of BeO Poisoning
Symptoms of BeO poisoning are respiratory distress, cyanosis (grey-blue
discoloration of the skin and mucous membranes), or both. These symptoms
may develop within a week, or after a period of several years.
