5.2.2
Grade of Toxicity
Beryllium Oxide dust is very dangerous if inhaled, even for only a few seconds.
It may cause injury to skin or mucous membranes severe enough to endanger
life or cause permanent injury. Particles penetrating the skin through wounds or
abrasions are liable to cause chronic ulcerations.
If an FE radio board containing Beryllium Oxide has exploded, the site must be
cleaned by authorized personnel, considering the rules and regulations of your
country. Dust can also be created if the ceramic form is broken, chafed or filed.
5.2.3
Symptoms of Poisoning
Symptoms of Beryllium Oxide poisoning are respiratory troubles or cyanosis
(grey-blue discoloration of the skin). These symptoms may develop within a
week or after a period of several years.
5.2.4
First Aid
Suspected inhalation of Beryllium Oxide must be treated immediately by a
doctor at a hospital.
Suspected skin contact with Beryllium Oxide or penetration of the skin through
cuts or abrasions must be treated by thoroughly washing the area with water
immediately. This should be followed by a medical examination.
5.2.5
Handling Components Containing Beryllium Oxide
As long as Beryllium Oxide is encapsulated in its ceramic form it is safe to
handle. The ceramic form must not be damaged in any way, for example, do not
file, ground, scrape or treat the ceramic with acid or mechanically damage it in
any way.
Components containing Beryllium Oxide must be treated with special care:
•
Compressed air should not be used to clean units containing Beryllium
Oxide.
•
Disused Beryllium Oxide components must be treated as environmentally
hazardous waste.
