WARNING, HEALTH RISK!
Beryllium oxide
The transistors in the power amplifier’s driver stage and in the power amplifier contain
beryllium oxide ceramics (BeO). Dust particles of this substance may be dangerous to
your health if you inhale or get them on your skin.
Therefore, DO NOT IN ANY WAY INTERFERE WITH THE TRANSISTORS. It is, vital
that you comply with the directions given in the appended “Beryllia safety precautions”.
BERYLLIA SAFETY PRECAUTIONS
Introduction
This appendix details the safety precautions when handling components containing
Beryllium oxide. Dust from this material can present a health hazard unless adequate
precautions are taken.
The hazard
The material is highly dangerous in a dust form when it might be inhaled or enter a cut
or skin irritation area.
If dust is caused as a result of chafing, filing or breakage and is inhaled, a single
exposure lasting minutes or seconds can 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 ulceration’s.
Symptoms of poisoning indicated by respiratory troubles or cyanosis (grey blue
discoloration of the skin), may develop within a week, or after a period extending to
several years.
