Maintaining Tools
To avoid accidents in the work place due to incorrect use of hand tools, it is a must that you understand the proper use of these tools. Study and practice proper use and maintenance of tools to prolong their life span and of course to avoid accidents due to improper or misuse of such tools.
Proper Use, Maintenance and Storage Tools
The use of safety hand tools should be a key component of most school 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 are guidelines maintaining and storing tools.
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 Information Sheet 1.1 Read Information Sheet 1.1 very well then find out how much you can remember and how much you learned by doing Self-check 1.1. CONSUMER ELECTRONICS SERVICING 131 K to 12 – Technology and Livelihood Education and heads redressed. This is essential to prevent eye damage resulting from chips detaching from the item during use.
Do not used 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.

Specifically, some tools require special care and maintenance due to their features and frequent use in any electronics or electrical job. Additional care and maintenance must be observed to the following:
Soldering iron
Always clean the tip before and after using. Do not wash the tip just to speed up its cooling process after using it. It might damage the heating element and corrode the tip.
Soldering gun
Be sure to tighten the two nuts holding the tip before using it to have maximum heat transfer to its tip.
Never use a soldering gun in mass production assembly. It might be overheated and will consume more power compared to a soldering iron.
