1. 1
INTRODUCTION
Post-accident investigations have revealed that the majority of accidents are caused by
unsafe practices. Most of these practices are known beforehand to be unsafe and in
violation of safety regulations. Other factors include fatigue, monotony, preoccupation at a
critical moment (inattentiveness), mental and/or physical problems, improper supervision,
and lack of motivation.
Humans make mistakes. By their action or inaction they cause, or fail to prevent,
accidents. In order to prevent accidents personnel must always be mentally and physically
alert to potential hazards. Training, reminders, and good personal examples will create a
climate of safety awareness.
Telecom safety deals with the hazards and safety precautions pertaining telecom,
equipment, their installation and maintenance. It is very important that all personnel know
and comply with all safety precautions and procedures.
SAFETY PRECAUTIONS
GENERAL SAFETY REQUIREMENTS
 Required warning signs (e.g., Danger Stack Gas, Danger High Voltage) must
be properly posted.
 Trained and qualified personnel should be allowed to install or replace
equipment.
 Obey all warning signs; read equipment warning labels before use.
 Use authorized equipment to perform maintenance work.
 Do not perform any action that creates a potential hazard to people or makes
equipment unsafe.
 Do not work alone if potentially hazardous conditions exist.
 Never assume, always double check.
 Use disposable dust masks for protection from inhalation of dust in dusty
environment.
Be Safety Smart Right From The Start

2. 2
PERSONAL ELECTRICAL/ELECTRONIC
EQUIPMENT
 All personal electrical and electronic equipment brought must be inspected by
designated personnel.
 Designated electronics technicians perform safety checks on electronic
equipment.
 Electronic equipment that is not double-insulated or that does not have a case
and handle made of non-conducting material and does not pass a inspection for
rugged, safe construction.
 Wear rubber gloves when using metal cased portable electric equipment or
hand held portable tools in hazardous conditions (e.g., wet floor). Wear leather
gloves.
 Only use tools and utilities that are in flawless condition. It is not permitted to
use visibly damaged tools.
WORKING ON ENERGIZED EQUIPMENT
 Personnel must never work on energized equipment alone. A safety observer
must be present.
 Never operate a switch with the other hand on a metal surface.
 If you are handling circuits with dangerous voltages always work with a
partner who knows the location of power supply switches.
 Always ensure adequate insulation when touching powered circuits.
ENSURING DE-ENERGIZATION
 Disconnect power supplies before working with the
equipment.
 Do not touch a conductor, until it has been verified that it is de-energized.
 Use a voltmeter or voltage tester to ensure that equipment or circuits are de-
energized.
 Ensure that the installation is not powered by an additional power supply or
protected via an additional fuse.
Your Safety Doesn’t Depend On Luck, It Depends On You

3. 3
WORKING AREA REQUIREMENTS
 The standing surface must be insulated from ground with insulating material
(rubber mat or insulated tiles or, when these are not available, dry wood, dry
canvas, dry phenolic material.
 Floor covering must be nonskid.
 Keep chassis area clean and dust free.
 The working area must be properly ventilated.
 Keep tools away from walk area where you and others could fall over them.
 Ensure good lighting at workplace.
 Untidiness at the work place involved the risk of injuries.
CLOTHING AND ARTICLES
 Do not wear loose clothing that could get caught in the
chassis. Fasten your tie or scarf and roll up your sleeves.
 When working on the installations always tieback long hair.
 Workers shall not wear watches, rings, watch chains, metal articles that might
accidentally contact energized circuits.
 Never wear jewelry or items such as metal fittings or metal rivets on items of
clothing.
 Clothing and articles shall be as dry as possible.
ELECTRONIC WORKBENCHES
 Bond and ground the workbench.
 Install a grounding bus for maintenance purposes.
 Install a disconnect switch to secure power to the workbench in case of electric
shock.
 Always put on the Electro-statically Sensitive Devices (ESD) wristband
before touching any of the boards or modules.
Safest Device Is The Safe Worker

4. 4
 Always place PC boards on a grounded conductive base and do not work on
the PC boards anywhere else.
 Only use grounded soldering irons.
HANDLING FIBER OPTIC CABLE
 Fiber optic cable must be handled, spliced and terminated by highly
experienced personnel because this is a very sensitive solution.
 These personnel must wear safety gloves while splicing any fiber optic cable.
 Improper handling of fiber optic termination equipment can lead to serious
injuries to human health because fiber optic glass is so thin that it cannot be
detected by any medical techniques, if penetrated in the body.
IN CASE OF AN ACCIDENT
WHAT TO DO IN EMERGENCY?
 In the events of accidents, remain calm and controlled.
 Always switch off the power supply before you touch an accident vicinity.
 If you are not able to switch off the power supply immediately only touch the
victim with non-conductive material e.g. wooden broom handle and first of all
try to isolate the victim from the power supply.
FIRST AID
You must be familiar with first practices in the events of injuries. A fundamental
knowledge of various resuscitation methods if the victim have heart is no longer beating.
Immediately call an ambulance or the emergency doctor. Give details of the accident in
the following order:
 Where did the accident happened?
 What happened?
 How many people were injured?
 Wait for questions.
Don’t Learn Safety By Accident
SAFETY IMPLEMENTATIONS

5. 5
Implement a comprehensive training program for all hands on
hazards and safety precautions pertaining to electronic systems,
equipment, and personal electronic equipment. As a first step
designate an electronic safety officer.
SAFETY OFFICER’S RESPONSIBILITIES
 Ensure that personnel engaged in operation and repair of electronic equipment
follow safety precautions.
 Ensure that required safety devices and warning signs are installed.
 Train electronics personnel in safety precautions and mishap prevention.
 Monitor mishap prevention by investigating all mishaps and near mishaps.
 Evaluate the effectiveness of the safety program by analyzing internal and
external reports.
 Ensure submission of occupational injury and illness reports.
 Recommend improvements to the safety program.
INDIVIDUAL RESPONSIBILITIES
Supervisors must set good personal examples and ensure that safety
precautions are strictly followed. All personnel must strictly observe
safety precautions. Accident prevention is everyone's business. All
personnel must:
 Observe posted operating instructions and safety precautions.
 Report any unsafe condition, equipment, or material.
 Warn others of hazards and failure to observe safety precautions.
 Wear approved protective clothing or use protective equipment as required.
 Report any injury or evidence of impaired health.
Don’t Leave Safety Habits At Work , Take Them Home
