INFORMATION SHEET 1.1

Plan and Prepare Tasks to Be Undertaken

Planning, as defined in the dictionary, is an act of formulating a


specific system for a definite course of action. It is a very essential part of
whatever task there is that needs to be undertaken as it aids one in preparing
for the tools/ materials to be used, lets one project the possible scenarios
that may arise (such as loose or damage to the tools).

This lesson aims to discuss the proper steps in planning and preparing for
the specific tasks to be undertaken.

Planning is a process of preparing for change and development and for


deciding how to best manage or influence those changes. Planning is also directed at resolving
specific problem issues or conflicts.

A Guide to Plan Preparation

The Policy background to Plan Preparation

Assessment- Students need to be aware of internal and external


risk factors and the consequences of any damage/ failure on their hand tools.

Prevention- The student should identify which hand tools is damaged.

Preparation of plans- A plan will be required to be realistic, flexible and meet all the
assessed needs of a student at the same time the hand tools itself and the likely needs of
recipients of the emergency response.

Education- Anyone involved to any extent in an emergency plan should be aware of his
role and be given the opportunity to practice actually doing it.

Testing / Exercising- Any plan must be tested to ensure that it encompasses all the
outcomes of known or reasonably foreseeable risks and that it would be effective in
providing a sufficient and timely response.

Review- There are a number of circumstances in which a plan may need to be reviewed.
Following any test of a plan, or its use in an emergency situation, it is important to
analyze whether the planned response was fully effective.

Response- The student should respond to incidents as part of their core activities. Others
may only very occasionally be asked to provide an emergency response.

Safety and Risk

An emergency does absolve teachers and students from their responsibilities, for their
health and safety. All emergency plans should therefore take account of the need to maintain
the highest possible standards of safety.
INFORMATION SHEET 1.2

List of Tasks to Be Undertaken

Most efforts to develop identification aids start and end with the
recognition key and its computer spin-offs, there are many other identification
tasks, starting with the most used: instant recognition. Here is a preliminary list
of identification tasks:

Each is briefly described below,


including a definition taken from Webster's
Unabridged Dictionary.
Recognition
"The identification of something as being of a certain kind"
Elimination
"To leave out of consideration"
Comparison
"The act of considering the relation between things in order to estimate their
similarities or differences"
Selection
"To choose in preference of others"
Selection is the opposite of elimination.

INFORMATION SHEET 1.3


Time Scheduling Suggestions
Time scheduling will not make you a perfectly efficient person. Very few
people can rigorously keep a detailed schedule day after day over a long period of
time. In fact, many students who draw up a study schedule and find themselves
unable to stick to it become impatient and often give up the scheduling idea
completely.
The following method of organizing time has been helpful to many
students and does not take much time. It is more flexible than many methods
and helps the student to establish long term, intermediate, and short term time
goals.

Intermediate Schedule - One per week

INFORMATIONSHEET 2.2

Unsafe or Faulty Tools

Hand Tools include a wide variety of non-powered devices such as wrenches, pliers,
hammers, and screwdrivers. These tools may seem harmless, but they are the cause of many
injuries. The Following are the summary of safety practices related to hand tools.

General hazards:

● The two most common hazards associated with the use of Hand Tools are misuse and
improper maintenance.
● Misuse occurs when a hand tool is used for something other than its intended purpose.
(An example would be using screwdriver as a chisel. This may cause the tip to break
and strike someone).
● Improper maintenance allows hand tools to deteriorate into an unsafe condition.
(Example would include cracked wooden handles that allow the tool head to fly off or
mushroomed heads that can shatter upon impact.
● Specially designed tools may be needed in hazardous environments. (Always use non-
sparking tools in the presence of flammable vapors and dusts. Insulated tools with
appropriate ratings must be used for electrical work).

Personal Protective Equipment:

● The type of PPE needed when using tools depends on the nature of the tank. At a
minimum, eye protection should always be worn.
● The use of hand protection may also be appropriate to provide protection against cuts,
abrasion, and repeated impact.

Do’s and Don’ts in Using Hand Tools

Pliers:

● Do not increase the handle length of pliers to gain more leverage. Use a larger pair of
pliers or bolt cutters.
● Do not substitute pliers for a wrench when turning bolts and nuts. Pliers cannot grip
these items properly and will slip.
● Never use pliers as a hammer on the handle. Such abuse is likely to result in cracks or
breaks.
● Cut hardened wire only with pliers designed for that purpose.
● Always cut a right angle. Never rock from side to side or bend wire back and forth
against the cutting edges.
Screwdrivers:

● Never use screwdrivers as a pry bar, chisel, and punch stirrer or scraper.
● Always use screwdriver tip that properly fits the slot of the screw.
● Throw away screwdrivers with broken or worn handles.
● Use magnetic or screw-holding screwdrivers to start fasteners in tight areas.
● Never use pliers on a screwdriver for extra leverage. Only use wrench or screwdrivers
specifically designed to accept them.

Utility Knives/ Blades:

● Always use a sharp blade. Dull blades require more force and thus are more likely to
slip. Replace the blade when it starts to “tear” instead of cut.
● Never leave a knife unattended with the blade exposed. Consider using a self-retracted
knife with a spring-loaded black. (The blade will retract when pressure as the knife is
released.
● Keep your free hand away from the line of the cut.
● Don’t bend or apply side loads to blades by using them to open cans or pay loose
objects. Blades are brittle and can snap easily.

Maintain Hand Tools

Teacher’s note:

To avoid accidents in the workplace resulting from the


incorrect use of hand tools, it will be important that you
understand the proper use of your items. Have your group discuss
your concerns about the dangers involved in using hand tools.
During the discussion, each member is reminded of correct
methods in manipulating hand tools. During the session, every
member practices the correct methods in manipulating hand tools.
It is important that everyone has an opportunity to use tools in the

INFORMATION SHEET 4.2

Proper Use, Maintenance and Storage Tools

The use of safety hand tools should be a key component of most industrial safety
programs. An understanding of the hand tool’s intended use and environment, combined
with proper tool selection, maintenance and storage, will greatly reduce the risk of harmful
accidents.

The following common-sense guidelines for Tool Use, Maintenance and Storage:

● Keep hand tools clean and free from ferrous or other


contaminants.
● Do not use hand tools in direct contact with acetylene, due to the
possible formation of explosive acetyl ides, especially in the
presence of moisture.
● During normal use, all pliers and screwdrivers will progressively develop some
damage to the striking faces of screwdrivers or the cutting edge and striking end of
pliers. As part of the normal operating and safety procedures, these tools should be
returned to the workshop, as with steel tools, to have the faces and heads
redressed. This is essential to prevent eye damage resulting from chips detaching
from the item during use.
● Do not hand tools fitted with wooden handles in places where the handles may dry
out and shrink. This will increase the risk of the handle breaking or the head
becoming loose.
● Tools are designed for specific use. As with any tool. In addition to the probability
that the tool will be damaged, this is a dangerous practice for the safety of the
operator.
● The accepted standards of safety and maintenance for common steel hand tools
must also be adopted with non-sparking hand tools, in addition to any specific
recommendations resulting from the alloys used.
● When sharpening hand tools, follow normal safety procedures, such as the
provision of eye and face protection, adequate extraction and dust collecting
facilities.
● Clean tools and equipment work more efficiently. At the end
of each working day clean the tools and equipment you used
and check them for any damage. If you note and damage,
tag the tool as faulty and organize a repair or replacement.

Electrical current can travel over oily or greasy surfaces.


Keep electrical power hand tools free from
dust and dirt and make sure they are free of
oil and grease.
Point to note:

All workshop hand tools and


equipment should have maintenance
schedule. Always complete the tasks
described on the schedule at the required
time. This will help to keep the hand tools in
safe working order.

Store commonly used hand tools in an easy-to-reach location. If a tool or a piece


is too difficult to return, it could be left on a workbench or on the floor where it will
become a safety hazard. Keep your work area tidy. This will help you work more
efficiently and safely.
