HOW TO USE THIS COMPETENCY BASED LEARNING MATERIAL
Welcome to the module in Prepare Pipes for Installation. This module contains training materials and activities for you to complete.
The unit of competency “Preparing Pipes for Installation” contains
knowledge, skills and attitudes required for Plumbing. It is one of the core
competencies at National Certificate level II (NCII).
You are required to go through a series of learning activities in order to complete each learning outcome of the module. In each learning outcome are Information Sheets and Instruction Sheets (Reference Materials for further
reading to help you better understand the required activities.) Follow these activities on your own and answer the self-check at the end of each learning outcome. You may remove a blank answer sheet at the end of each module (or
get one from your facilitator/trainer) to write your answers for each self-check.
If you have questions, don’t hesitate to ask your facilitator for assistance.
Recognition of Prior Learning (RPL)
You may already have some or most of the knowledge and skills covered
in this learner’s guide because you have:
been working for some time
Already completed training in this area.
If you can demonstrate to your trainer that you are competent in a
particular skill or skills, talk to him/her about having them formally recognized
so you don’t have to do the same training again. If you have a qualification or Certificate of Competency from previous training, show it to your trainer. If the skills you acquired are still current and relevant to the unit/s of competency
they may become part of the evidence you can present for RPL. If you are not sure about the currency of your skills, discuss this with your trainer.
At the end of this module is a Learner’s Diary. Use this diary to record
important dates, jobs undertaken and other workplace events that will assist
you in providing further details to your trainer or assessor. A Record of Achievement is also provided for your trainer to complete once you complete
the module.

Learning Objectives:
After reading this INFORMATION SHEET, YOU MUST be able to
explain, identify standard plumbing symbols, abbreviation.
INTRODUCTION
In addition to practical training with tools and materials, a plumber must
learn to the plumbing symbols and abbreviation. It is difficult for a plumber to make any interpretation of a plan if he/ she do not know the plumbing symbols and abbreviation indicated in the plumbing layout or print and specifications
SYMBOLS AND ABBREVIATIONS A common set of symbols are used on architectural prints to represent
materials, building objects, and various dimensions and locations. Piping symbols are used by architect and mechanical engineers on prints to represent plumbing fixtures and piping systems, as well as pipe fittings and valves used
to construct plumbing systems. A print is a drawing showing a building structure and all of its
components. Prints are also referred to as blueprints or working drawings. Specifications are written information that supplements the prints and
provides additional details that could not be shown on the prints or that
require additional description such as information on legal responsibilities, insurance, quality of workmanship, and other necessary details such as
brands and types of plumbing fixtures and equipment. See figure 1.1
Note: Symbols and Abbreviations in plumbing trade may appear similar in
other qualification but it may have different meaning and application.

Information Sheet No. 1.1-4 Hand and Power Tools safety
Learning Objectives:
After reading this INFORMATION SHEET, YOU MUST be able to
explain, identify and perform safety handling of hand tools.
INTRODUCTION:
In this information sheet contains OH& S on handling both hand and power tools. One’s a plumber practice safe handling of tools he/ she can avoid accident, injury which may result into death or damage to property. On the
other hand if the plumber did not practice such safety handling of tools it may have a reverse result.
HAND AND POWER TOOL SAFETY
Plumbing tools are classified into two; the HAND TOOLS and the POWER
TOOLS.
Differences between hand and power tools:
– Hand tools have no power source, other than the physical force
applied by the user. Hand tools include anything from axes to
hammers, and screwdrivers to wrenches
– Power Tools require a non-human power source to function
properly--e.g. External (electricity, compressed air, etc.) or
Internal (battery pack, internal combustion engine, etc.).
Both kinds of tools require specific safety precautions or rules to be
followed; yet some rules will apply to both.
