Films
from D. Douglas Dent, Inc.
Accumulatively,
this series of training films was designed to lead forestry personnel
through many of the topics discussed in Professional Timber Falling.
Topics are arranged in such an order that viewers are led step-by-step
through the entire harvesting sequence. Personnel are shown how
they can interweave safety and technique into a well-coordinated
approach which will result in a safe, correct and efficient completion
of tasks. Whether the task at hand is cutting firewood, pruning
trees, removing brush or logs from trails, falling trees in forest
fires or professionally cutting, these training aids have been
found to be invaluable training tools.
1.
Timber Falling - An Introduction
The
theme of this film revolves around the philosophy that the worker
must learn to protect himself at all times. Although there are
various ways in which self-protection can be achieved, this film
examines one of the most important, a good safety attitude. The
significance of attitude becomes very real through the interviews
of two injured workmen.
2.
Safety Equipment
The
theme of this film revolves around the fact that one of the ways
worker's can insure their well-being is through the use of personal
safety equipment and clothing. Each essential piece of safety
gear is identified and the specific hazard it addresses is discussed
in detail.
3.
Safe Chain Saw Use
Annually,
the majority of forestry accidents involve the chain saw and this
film examines why. The theme of Safe Chain Saw Use lies in the
belief that the chain saw is merely a tool and, therefore, cannot
initiate action by itself. Rather, all it can do is respond to
the situations, dangerous or not, that it is placed into. As such,
this film discusses such important topics as, proper starting
procedures, the safest method of controlling the saw at all times
and dangerous portions of the bar tip.
4.
Limbing
Limbing
is the process of sawing branches from a tree. Although this process
may appear to be elementary, it is the limbing activities, in
conjunction with the chain saw, which results in a significant
number of injuries each year. This film illustrates how this activity
can be safely accomplished and examines the most common mistakes
make and hazards most likely to be encountered.
5.
Bucking
This
film examines the safety measures, procedures and techniques required
to buck or cut trees into sections. Various tree positions and
the resulting bind forces compression and tension) are discusses
and the safest methods of handling them are illustrated.
6.
The Undercut, Holding Wood and Backcut
At
the most basic level, the felling of a tree requires the insertion
of three separate cuts: a horizontal cut, sloping cut and a backcut.
This film examines the relationship of these three cuts to one
another, their combined relationship to the tree being felled
and how their correct use enables trees to be felled in a safe,
controlled and precise manner.
7.
Improper Undercutting
Improper
undercutting is designed to identify and discuss in depth the
most common mistakes made during the felling sequence. Numerous
forms of improper undercutting are shown, discussed and evaluated
on the basis of why they are improper, how specific mistakes alter
the constant relationships of the three stump cuts, and how such
error's can be recognized and corrected.
8.
The Felling Procedure
The
Felling Procedure is a systematic approach to the felling of trees
in a safe, correct and efficient manner. The felling sequence
is a critical time for the worker and each year many worker's
are crippled or killed performing this required task. The importance
of this film lies in the fact that adherence to a step-by-step
approach enables the worker to identify and eliminate various
hazards each tree presents. As such, workers are shown how they
can interweave safety, hazard abatement and technique into a well
coordinated effort.
9.
Sit-Backs
The
term sit-back refers to the settling of a tree back on the stump
and opposite the desired falling direction. This film examines
why this dangerous situation occurs, how it can be prevented and
how sit-backs can be safely and effectively handled. The techniques
of driving, backfalling and wedging are illustrated.
10.
Snags
This
film critically examines a source of danger which has and continues
to injure, cripple and kill an unusually significant number of
workers each year. Snags, being comprised of defective wood fibers,
are so dangerous because they can fall at any time and in any
direction. As such, this film depicts a special felling procedure
which will enable the worker to safely, correctly and efficiently
fall snags.
11.
Crosscutting - Using Cross Cut Saws
This
film applies many of the concepts, techniques and procedures of
chain sawing to the art of using a cross cut.
12.
Standard Fire Cutting Orders
This
brightly colored and durable plastic card, which fits into a shirt
pocket, is used by firewood cutters, professional loggers and
particularly, by fire fighters (forest fires). On one side it
identifies the most important safety measures, techniques and
procedures required to safely fall trees. On the other, appropriate
and required illustrations of the undercut, holding wood and stump
shot are illustrated.
