Condition of tools and equipment

Knowing of functional and non- functional tools is a primary concern of workers to be effective and safe in doing their jobs

Functional tools and equipment are those that are in good condition and can perform their regular functions.

Non-functional tools and equipment are those that are not able to perform their regular function because of impaired and damaged part.

Tools that are no longer functional may cause harm.

Below are the recommended practices to identify functional and non- functional hand tools.

1. Visual inspection:

Defective tools can easily be distinguished from the functional ones through visual inspection. The physical appearance of tools will describe such characteristics as dullness, sharpness, dismantled parts, and unevenness of the teeth of the cutting tools.

2. Functionality:

Another way is to check the quality of the manufactured tools. Is it already susceptible to wear and tear? Has it already exceeded its service life? Has it passed the manufacturer’s quality control test?

A few pieces of the hand tools issued in the shop can be subjected for condemnation they are no longer serviceable. Some hand tools issued for years in shops and few pieces of these can be subjected for condemnation.

3. Performance: Performance of hand tools is determined not only during the actual use but also after use to find out whether the hand tools are still worth using.

4. Service span: Hand tools are issued to shop teacher at one time. However, this must be recorded to determine when it was received and how long the tools have been kept in the shop. A hand tool which is too old is unsafe for both the students and workers. Such tool should be marked defective and segregated from the good ones.

CHECKING CONDITION OF TOOLS

Non-functional tools and equipment must be reported in the report card. The

following tools and equipment are used in checking the condition of tools.

CLASSIFICATION OF TOOLS AND EQUIPMENT

· Driving tools

· Boring tools

· Cutting tools

· Holding tools

· Measuring tools

· Testing tools

Support materials

· Inventory Sheet

· Report Card

Basic Maintenance

Maintenance of hand tools and machines are both primordial concerns of a repair

technician in the welding shops and/or in the welding production. The activities should be on

schedule and with proper coordination with the production people. The term “repair” and

“maintenance” works mean differently. Repair, unusually focuses on the program of works done

in the operation of power plants in machines that are in trouble of stopping its function. While the term “maintenance” means a scheduled or a planned visit of tools or equipment for inspection and from there, reports and recommendation developed and the next tasks to be decided such as cleaning, application of lubricants, dismantling and etc.

Some of the simple maintenance activities for hand tools, and the maintenance schedule should

be posted in a visible corner of the shop where everybody can read it.

Routine maintenance of hand tools is undertaken according to standard operating procedures, principles and techniques.

· Cleaning. Simple process applied to hand tools-

The cleaning approach may differ from one another. For example, cleaning of the rack corners of hand tools by using air vacuum or by a piece of clothes. Similar process may be applied to identical cleaning situations.

· Lubricating-

A task performed in the shop/production. Through the application of lubricant substance to the identified items in parts like barrels, rollers, springs, bearing,bolts and nuts, and other automotive parts.

· Tightening/Loosening-

In an assembly of structures, we have tools for fittings that need to be tightened and loosened and in as much as they pose high risk to safety. Tightening bolts and nuts and other fittings requires procedures should carried out in compliance with manufacturers manual.

· Simple Repair-

Repair practices of hand tools are still available anytime. But, to some extent, tools are checked yearly and many of the hand tools are eligible for condemnation and the whole items are to be replaced by a new unit. However, there are instances that minor repair can be performed, like replacement of wooden handle of a hammer and mushroomed head of a cold chisel.

· Tools for hand Sharpening-

Some tools need to be sharpened such as blades of knife, cold chisel, punches and many others. To do hand sharpening for hand tools requires techniques and application. In some multi knives cutter, manufacturers produce knife sharpening system to hold or clamp the blade for ensuring strong blade to stone contact during sharpening and also provided with course to fine honing stones. For cold chisel and punches, the right file-size and grades are used for repairing the defective anvil curve.

CLASSIFICATION OF LUBRICANTS

Before using the tools and equipment in the installation of pipes, you have to first

know the types of lubricants to use. Lubrication prevents the rusting and malfunctioning of

tools and equipment.

There are four types of lubricants, and these are:

1. Liquid

2. Solid

3. Grease

4. Paste

Liquid lubricants such as: emulsion and suspension are made from lanolin natural water, and these lubricants inhibit rust, salt, and acids from forming.

Water can also be used as a lubricant mixed with other base oils.

Mineral oils which are derived from crude oil are of very high quality as lubricants.

Vegetable oil which is primarily triglyceride esters derived from plants and animals can

also serve the purpose as a lubricant and is environment friendly.

Solid lubricants are rarely used directly, commonly it is added

Solid Lubricants are used together with other lubricants to increase its lubricating properties. Examples of solid lubricants are Graphite, Molybdenum disulfide, mica, talc or soap, lead carbonate, wax, etc

Greese sometimes called semi solid lubricant is a thick oily substance made from soap emulsified and mineral or vegetable oil used mainly on bearings etc.

Paste Lubricants are used to form a lubricating film to separate component surfaces which is efficient even under extreme conditions. It is usually used for applications requiring high load-carrying capacity such as heavy equipment parts and components

Purpose for Lubricating

Here are the benefits from lubricating tool and equipment:

- keeps moving parts apart

- reduces friction

- transfers heat more efficiently

- carries away contaminant and debris

- transmits power more efficiently

- protects against wear

- prevents corrosion

Proper Storage of Tools and Equipment

1. Clean the cabinet or tool room.

2. Classify the functional and the non functional tools.

3. Non-functional tools are segregated and labeled.

4. Clean tools and equipment.

5. Store idle tools when not in use.

6. Tools should be stored in a dry and safe place.

7. Keep tools and equipment clean, with oil and unplug from power source.

8. Hand tools are stored in designated location in accordance with manufacturer’s instruction or standard operating procedure

Good practices of proper storage of tools:

1. Parts should be properly stored and labeled.

2. Tools should be properly placed on the board, and labeled. Consider drawing the shapes of the tools on the board so that they always get put back in the same position.

3. Use bins for storing small parts.

4. Consider making an individual (or individuals) responsible for the good maintenance of tools and parts

Benefits of proper storage of tools:

1. Tools and parts are kept in good condition and are easy to find

2. Costs are reduced

3. Productivity is increased because time is not lost looking for tools, parts and equipment

4. Workshop staff develop a sense of responsibility and pride in their work.
