Technical Writing: Descriptions and Instructions
As a professional communicator it is often necessary to create technical documents such as description or instruction sheets, or even process diagrams. To ensure compliance, successful completion of an assigned task, or consistency in performance, technical instruction sheets serve as learning tools and resources while a technical description may clarify nomenclature. Here is a sample of a technical description sheet based on the form and function of the Zippo lighter.
Zippo
Lighter Description
Introduction
Since
its introduction in 1933, the Zippo lighter has proven to be a dependable and
iconic lighter. The following description is intended to familiarize new users or
collectors with basic user information such as dimensions, nomenclature, and safety
precautions. By appreciating the potential dangers involved in keeping
collectible lighters in the home, it becomes easier to preserve the mechanism
while avoiding potential hazards.
Description
In
1936, the U.S. Patent office granted George Blaisdell (b. 1895, d. 1978) patent
number 2032695 for his “Windproof”
lighter. The approximate dimensions of the basic model closed are a) Height
2-inch, b) Width 1-inch, and c) Depth ½-inch (Unknown, 2012). The approximate weight is 2.05 oz. dry
(Unknown, 2012). Each Zippo lighter comes with a lifetime warranty.
This
image depicts a standard Zippo in the ‘open’ position. The lighter’s
outer metal housing (or sleeve), is comprised of a Brass Lid, Brass Bottom Case, and Hinge Pin (Figure 1). This brass sleeve protects the Inside Case, Flint Wheel, and Flint Rivet
(Figure 1). Housed within the Inside Case
are the Flint, Flint Spring, Flint Spring
Tip, Flint Screw, Rayon Balls, felt pad, and wire-reinforced wick (inner parts not shown).
Warning
Although
Zippo Lighters have been a popular collectible since World War II, one should
remember the purpose for which these mechanisms were devised; the Zippo is
designed to burn once ignited (even in high wind), as long as there is a fuel
source. Balisdell’s creation performs this function extremely well even without fluid. Therefore, a Zippo should always be kept out
of the reach of children. The mechanism is deceptively easy to use.
By simply
rotating the Flint Wheel downward (or
clockwise), the wheel engages the flint (if present) creating hot sparks known
to burn clothes, skin, etc. (Figure 2). For example, the U.S. Air Force teaches
the participants of Survival and Air Base Ground Defense schools to use a Zippo
Lighter - with flint only - to ignite steel wool, shredded paper, and wooden
fibers as a means of starting a fire.
Therefore, due caution should be exercised in using, collecting, or
storing this device.
