2 Personal Health and Safety Information
2.1 Introduction
This document presents the personal health and safety information that applies
when working with Ericsson system products. The instructions included are
mandatory to ensure personal safety while working with Ericsson system
products.
Note: Reduce the risk of accidents by studying all the information carefully
before starting work. If questions arise regarding health and safety
information, contact the supervisor or the local Ericsson company for
clarification.
For information on product safety for Ericsson system products, see:
System Safety Information,
Ericsson System Products
124 46–2886
Local Regulations
Local regulations, first and foremost national regulations, override the
information in this document. Where applicable local regulations are not
available, the information herein prevails.
Product Exclusion Indication
The information in this document covers personal health and safety aspects
of all Ericsson system products. As all the information does not apply to a
specific product, the readers must familiarize themselves with the potential
hazards indicated on the product they are working with to understand which
document parts apply to their product.
2.1.1 Target Group
The target group for this health and safety information is personnel who work
with Ericsson products. All personnel who work with engineering, installation,
test, and operation and maintenance of Ericsson products must familiarize
themselves with this information.
2.1.2 Educational Requirements
The safety instructions in the relevant manuals or documents require that
persons performing work on Ericsson products have the necessary education,
11
EN/LZT 720 0027 Uen R8A 2006-06-27

RBS 2308 and RBS 2309 User’s Guide
training and competence required to perform work correctly. For certain work,
additional or special training may be required, for example authorization for
Authorized Service Providers (ASP). ASP is an Ericsson certification procedure.
A good understanding of technical English is required, or of the language that
the information is presented in, to ensure that these and other instructions
can be understood and complied with.
2.2 Hazard Symbols and Admonitions
This section presents the types of admonitions and hazard symbols used in all
Ericsson documentation. There are three levels of personal health and safety
admonitions that indicate risk to persons: danger, warning and caution. Hazard
symbols are used to indicate these and to present various other hazards.
The admonition levels for personal health and safety are presented in order
of severity, with danger being the highest level, warning the intermediary
and caution the lowest. When admonitions are encountered anywhere in a
document, the information included should be read and any instructions should
be followed.
2.2.1 Personal Health and Safety Admonitions
Personal health and safety admonitions are used to indicate hazardous
activities and are normally preceded by the common hazard symbol shown in
the figure below, or in specific cases by specialized symbols, see Section 2.2.2
Special Hazard Symbols on page 13.
P002643A
Figure 5 Safety Hazard Symbol
The hazard symbol is common for all three admonition levels. The three
admonition levels are defined below:
Danger! Indicates that there is an imminent hazard that is likely
to result in death or serious injury.
Note: Danger can be accompanied by other symbols
depending on the country of operation.
Warning! Indicates that there is a potential hazard that could
result in death or injury.
Caution! Indicates a hazard that could result in minor or moderate
injury.
