Glossary of Terms:

Core Competencies - are the specific skills and knowledge needed in a particular area
of work - industry sector/occupation/job role

Aerial Cable – suspended and attached on telephone pole for distribution porposes.

Communication Cable – is used for the distribution and small copper wires for voice
and data signals

Copper cable -- Electric power cables made from twisted pair copper wire.

Environment - The area surrounding the work site which can be directly or indirectly
affected by occurrences at the work site. It includes the atmosphere, soils, drains,
underground water tables, and the ecosystem. Protection of the environment would
require the proper disposal of waste materials, restriction of burning off, the correct
handling of toxic substances, the containment of CFCs and the like.

Hazardous Materials - Flammable gases and vapors and combustible dusts.
Pre-cautions:

A measure taken in advance to avert possible evil or to secure good results

OPERATION SHEET

PURPOSE: • Is to prepare the required tools, materials and equipment
prior to installation.

• To install pole hardware, cable terminal, line wire and
accessories

PROCEDURE: 1. Arrange tools, materials and equipment needed..
PRECAUTIONS: 2. Extend ladder to pole.as per manufactures specifications

and techniques.
3. Wear safety gadgets to prevent accident
4. Ascend and descend on pole with care
5. Sheath opening of main cable
6. Bonding and grounding are installed per outside plant

standards
7. Loop and bends are made to ensure standards are

followed.

1. Practice placement or installation of collapsible sign to
prevent accident.

2. For body belt and safety traps, look for the following
defects:
A. Leather cracks, cut tears, broken stitches and
loose rivets.
B. Defective buckles, snap hooks, keepers and d-ring.
Should there be any defect, correct them before
using the equipments.
C. If the defect can be corrected change the
equipment into new ones.

QUALITY CRITERIA: 1. Extended ladder should be properly in placed

2. Completeness of tools and materials are necessary

3. Proper usage of tools and materials must be
observed

4. Correct installation of main cable and groundings.

5. Measurements and supports are observed to
protect sagging.
