Title
Unit Lesson
So far in the course, we have discussed the history of safety,
causation models for safety, how to perform
an investigation, and the role of human factors in accidents. In
this unit, we start to look at how those
variables apply to some hazards that you might face in your
safety job—specifically mechanical hazards and
fall hazards.
Two important concepts that students must be familiar with in
this course are hazards and risks. While at first
glance, these terms appear to be relatively easy to understand,
many students are easily confused, using the
terms interchangeably. Hazard and risk are not identical
variables. A hazard is anything that has the potential
to cause harm. The harm can be to an individual, the
environment, or physical property like a structure. There
are several common definitions of risk, but the most common is
the probability that the hazard will cause harm
and the severity that would be associated with the harm.
Part of the safety professional’s job is to identify hazards that
are present at a workplace. There are multiple
methods for the safety professional to identify hazards,
commonly referred to as a hazard analysis. We will go
into some specific hazard assessments in greater detail in Unit
VII as they are associated with management
programs. For this unit, we will look at risk assessment of some
specific hazards that we have already
identified.
If you are a safety professional working in an industrial
manufacturing facility, you have most likely
encountered some mechanical hazards. Machines are required
for most modern manufacturing processes. In
the early days of the Industrial Revolution, many machines were
driven by either human or animal power. As
scientific knowledge increased, steam power became much more
prevalent. Finally, with the advent of
electricity, human- and animal-powered machines became
obsolete. Today, most machines are powered by
electricity, hydraulics, pneumatics, or some combination of the
three. Another increasingly common variable is
the use of robotics in manufacturing processes. Each of these
power sources represents a hazard in the
workplace.
The questions that the safety professional must answer are: how
likely are employees to be injured when
interacting with these hazards? And, how seriously can they be
injured? One concept that is important for you
to understand deals with residual risk. Optimally, a safety
professional would like to create a workplace where
the risk of injury and illness was zero. This goal is unrealistic.
Whenever a hazard is present in a workplace,
some level of risk will always be present. In other words, you
cannot have a hazard with zero risk. Therefore,
the only way to get rid of all risk associated with a particular
hazard is to remove the hazard completely from
the workplace. In most cases, this is not possible because the
hazard is necessary for the production
process.
The realistic goal of the safety professional is to reduce the risk
associated with a specific hazard to an
acceptable level. First, there needs to be a method of assessing
the risk associated with a hazard. Then,
there needs to be a way to determine if the risk is acceptable.
The concept of acceptable risk is very
subjective. What some might consider an acceptable level of
risk associated with a process, others might
consider to be unacceptable. If you have a way to quantify the
risk, say give it a number rating, the evaluation
may be easier.
Fortunately, there are several risk assessment methods that have
already been devised and are in common
use in the safety field. One method, using a decision tree, is
presented in Chapter 14 of the textbook
(Goetsch, 2019). A very common method used currently by
safety professionals is the risk assessment
matrix. In this type of matrix, one axis addresses the likelihood
of harm and the other axis addresses the
severity. Matrices exist with three choices per axis (3 X 3
matrix), four choices per axis (4 X 4 matrix), and five
choices per axis (5 X 5 matrix). An example of a 5 X 5 risk
assessment matrix appears below.

Sample 5x5 risk assessment matrix
Looking at the matrix, you can see that the results are colored
red, orange, yellow, or green. These colors
represent the level of risk, with red being the highest risk and
green being the lowest risk. You may decide
that orange and red represent unacceptable levels of risk and
require corrections, while yellow and green
represent acceptable levels of risk and do not require
corrections. Understand though, that there are no
regulatory requirements as to which levels to rate as red,
orange, yellow, or green (or even which colors to
use in a matrix), or which levels are acceptable and
unacceptable. The decisions are purely subjective.
The way most safety professionals use the risk assessment
matrix is to complete a risk assessment on an
identified hazard. Once the risk level is calculated, a decision is
made as to whether the risk is acceptable or
unacceptable. If the risk is unacceptable, corrective measures
are implemented, and the risk assessment is
repeated with the new control measures in place. This process is
repeated until the residual risk has been
reduced to an acceptable level.
Let’s look at an example. Figure 14-8 (page 315) in the
textbook shows a picture of a shearing machine
(Goetsch, 2019). Obviously, this is a hazard in the workplace. If
we performed a risk assessment using the 5
X 5 matrix above before any controls have been added, we
would probably say the likelihood of injury would
be very likely, and the severity would at least be permanent
partial disability (or maybe the higher category of
death). We can all agree that a level of risk of 20 or 25 would
be unacceptable. We decide to install the
controls that are shown in Figure 14-8, which require both the
foot pedal and the hand button to be pushed at
the same time for the shear to operate.
When we perform a second risk assessment with the controls in
place, we might now rate the likelihood as
unlikely since the operator would need to purposely place the
free hand inside the machine while both
pressing the hand button with his/her other hand and stepping
on the foot pedal. However, the severity would
still be the same if an accident did occur. This would reduce the
risk to a score of 4, 5, 6, 8, or 10 (green,
yellow, or orange), depending on which likelihood and severity
you chose. We can agree that the level of risk
has been significantly reduced. Some of you may still rate the
risk as being unacceptable, and you may
implement additional controls, like installing a light curtain of
boxing in the shear. You would then perform
another risk assessment after the new controls have been
installed.
The primary task the safety professional would have in the
above scenario would be choosing a control
method that reduced the risk to an adequate risk level and
convincing management that the controls were
necessary. Using the results of a risk assessment is a good way
to help convince management of the need
MOS 5101, Safety and Accident Prevention 4
UNIT x STUDY GUIDE
Title
for the expenditure. Chapter 14 contains some examples of
controls that can be used for reducing risk
associated with mechanical hazards (Goetsch, 2019).
Falls have become a major source of injuries and deaths in the
United States, especially in the construction
industry. Based on the lessons we learned in our first four units,
we know that falls can be caused by unsafe
conditions or unsafe behaviors (human factors). Because of the
risk of injury from fall hazards, the
Occupational Safety and Health Administration (OSHA) has
implemented a regional emphasis program for
falls in the construction industry. OSHA (2017) has also
published multiple standards for fall hazards.
You can perform a risk assessment for fall hazards using the
same procedures we illustrated for mechanical
hazards. For example, if we were evaluating the fall hazard
associated with a roofing crew working on a two-
story residential building with no controls, we would probably
rate the likelihood as very likely. This rating
could be reached by reviewing the number of falls in residential
roofing projects each year (information can be
obtained on OSHA’s website). The severity would probably be
rated as death or permanent total disability
based on the number of deaths and permanent disabilities from
falls each year. The rating of 25 would
definitely be unacceptable.
There are many control methods that are available for fall
hazards. Some of the control methods are
described in Chapter 15 of the textbook. A large problem for
safety professionals is getting workers to actually
use the controls. This can especially be difficult on construction
projects. Most residential roofing projects you
see while driving through neighborhoods either do not use any
fall protection, or use controls that would only
minimally reduce risk. For example, many workers on roofing
projects use foam knee pads on which they
kneel while working as their fall protection. You can see that a
risk assessment of a roofing project using that
control method would still end with a rating of 15-20, which
would be unacceptable. For that reason, OSHA
recently started requiring the use of approved fall protection
methods instead of these alternate methods.
Approved fall protection methods for roofing projects would be
a fall protection system (think fall arrest
harness) with an anchor point on the roof or a netting system
around the roof. If we performed a risk
assessment with one of these controls, the risk would be
reduced significantly to a point that most of us would
say is acceptable.

  • 4. So far in the course, we have discussed the history of safety, causation models for safety, how to perform an investigation, and the role of human factors in accidents. In this unit, we start to look at how those variables apply to some hazards that you might face in your safety job—specifically mechanical hazards and fall hazards. Two important concepts that students must be familiar with in this course are hazards and risks. While at first glance, these terms appear to be relatively easy to understand, many students are easily confused, using the terms interchangeably. Hazard and risk are not identical variables. A hazard is anything that has the potential to cause harm. The harm can be to an individual, the environment, or physical property like a structure. There are several common definitions of risk, but the most common is the probability that the hazard will cause harm and the severity that would be associated with the harm. Part of the safety professional’s job is to identify hazards that are present at a workplace. There are multiple methods for the safety professional to identify hazards, commonly referred to as a hazard analysis. We will go into some specific hazard assessments in greater detail in Unit VII as they are associated with management programs. For this unit, we will look at risk assessment of some specific hazards that we have already identified. If you are a safety professional working in an industrial manufacturing facility, you have most likely encountered some mechanical hazards. Machines are required for most modern manufacturing processes. In the early days of the Industrial Revolution, many machines were driven by either human or animal power. As
  • 5. scientific knowledge increased, steam power became much more prevalent. Finally, with the advent of electricity, human- and animal-powered machines became obsolete. Today, most machines are powered by electricity, hydraulics, pneumatics, or some combination of the three. Another increasingly common variable is the use of robotics in manufacturing processes. Each of these power sources represents a hazard in the workplace. The questions that the safety professional must answer are: how likely are employees to be injured when interacting with these hazards? And, how seriously can they be injured? One concept that is important for you to understand deals with residual risk. Optimally, a safety professional would like to create a workplace where the risk of injury and illness was zero. This goal is unrealistic. Whenever a hazard is present in a workplace, some level of risk will always be present. In other words, you cannot have a hazard with zero risk. Therefore, the only way to get rid of all risk associated with a particular hazard is to remove the hazard completely from the workplace. In most cases, this is not possible because the hazard is necessary for the production process. The realistic goal of the safety professional is to reduce the risk associated with a specific hazard to an acceptable level. First, there needs to be a method of assessing the risk associated with a hazard. Then, there needs to be a way to determine if the risk is acceptable. The concept of acceptable risk is very subjective. What some might consider an acceptable level of risk associated with a process, others might consider to be unacceptable. If you have a way to quantify the risk, say give it a number rating, the evaluation
  • 6. may be easier. Fortunately, there are several risk assessment methods that have already been devised and are in common use in the safety field. One method, using a decision tree, is presented in Chapter 14 of the textbook (Goetsch, 2019). A very common method used currently by safety professionals is the risk assessment matrix. In this type of matrix, one axis addresses the likelihood of harm and the other axis addresses the severity. Matrices exist with three choices per axis (3 X 3 matrix), four choices per axis (4 X 4 matrix), and five choices per axis (5 X 5 matrix). An example of a 5 X 5 risk assessment matrix appears below. MOS 5101, Safety and Accident Prevention 3 UNIT x STUDY GUIDE Title Outcomes Likelihood Severity Rating Health Property Environment Very Likely
  • 7. Likely Possible Unlikely Very Unlikely 5 4 3 2 1 5 Death or Permanent Total Disability Catastrophic Loss Significant Impact, Irreversible 25 20 15 10 5 4 Permanent Partial Disability Severe Damage Significant Impact, Reversible 20 16 12 8 4 3 Injury or Illness With Lost Workdays
  • 8. Significant Damage Moderate Impact, Reversible 15 12 9 6 3 2 Injury or Illness With no Lost Workdays Moderate Damage Minimal Impact 10 8 6 4 2 1 First Aid Only or no Treatment Light Damage No Impact 5 4 3 2 1 Sample 5x5 risk assessment matrix
  • 9. Looking at the matrix, you can see that the results are colored red, orange, yellow, or green. These colors represent the level of risk, with red being the highest risk and green being the lowest risk. You may decide that orange and red represent unacceptable levels of risk and require corrections, while yellow and green represent acceptable levels of risk and do not require corrections. Understand though, that there are no regulatory requirements as to which levels to rate as red, orange, yellow, or green (or even which colors to use in a matrix), or which levels are acceptable and unacceptable. The decisions are purely subjective. The way most safety professionals use the risk assessment matrix is to complete a risk assessment on an identified hazard. Once the risk level is calculated, a decision is made as to whether the risk is acceptable or unacceptable. If the risk is unacceptable, corrective measures are implemented, and the risk assessment is repeated with the new control measures in place. This process is repeated until the residual risk has been reduced to an acceptable level. Let’s look at an example. Figure 14-8 (page 315) in the textbook shows a picture of a shearing machine (Goetsch, 2019). Obviously, this is a hazard in the workplace. If we performed a risk assessment using the 5 X 5 matrix above before any controls have been added, we would probably say the likelihood of injury would be very likely, and the severity would at least be permanent partial disability (or maybe the higher category of death). We can all agree that a level of risk of 20 or 25 would be unacceptable. We decide to install the controls that are shown in Figure 14-8, which require both the foot pedal and the hand button to be pushed at the same time for the shear to operate.
  • 10. When we perform a second risk assessment with the controls in place, we might now rate the likelihood as unlikely since the operator would need to purposely place the free hand inside the machine while both pressing the hand button with his/her other hand and stepping on the foot pedal. However, the severity would still be the same if an accident did occur. This would reduce the risk to a score of 4, 5, 6, 8, or 10 (green, yellow, or orange), depending on which likelihood and severity you chose. We can agree that the level of risk has been significantly reduced. Some of you may still rate the risk as being unacceptable, and you may implement additional controls, like installing a light curtain of boxing in the shear. You would then perform another risk assessment after the new controls have been installed. The primary task the safety professional would have in the above scenario would be choosing a control method that reduced the risk to an adequate risk level and convincing management that the controls were necessary. Using the results of a risk assessment is a good way to help convince management of the need MOS 5101, Safety and Accident Prevention 4 UNIT x STUDY GUIDE Title
  • 11. for the expenditure. Chapter 14 contains some examples of controls that can be used for reducing risk associated with mechanical hazards (Goetsch, 2019). Falls have become a major source of injuries and deaths in the United States, especially in the construction industry. Based on the lessons we learned in our first four units, we know that falls can be caused by unsafe conditions or unsafe behaviors (human factors). Because of the risk of injury from fall hazards, the Occupational Safety and Health Administration (OSHA) has implemented a regional emphasis program for falls in the construction industry. OSHA (2017) has also published multiple standards for fall hazards. You can perform a risk assessment for fall hazards using the same procedures we illustrated for mechanical hazards. For example, if we were evaluating the fall hazard associated with a roofing crew working on a two- story residential building with no controls, we would probably rate the likelihood as very likely. This rating could be reached by reviewing the number of falls in residential roofing projects each year (information can be obtained on OSHA’s website). The severity would probably be rated as death or permanent total disability based on the number of deaths and permanent disabilities from falls each year. The rating of 25 would definitely be unacceptable. There are many control methods that are available for fall hazards. Some of the control methods are described in Chapter 15 of the textbook. A large problem for safety professionals is getting workers to actually use the controls. This can especially be difficult on construction projects. Most residential roofing projects you
  • 12. see while driving through neighborhoods either do not use any fall protection, or use controls that would only minimally reduce risk. For example, many workers on roofing projects use foam knee pads on which they kneel while working as their fall protection. You can see that a risk assessment of a roofing project using that control method would still end with a rating of 15-20, which would be unacceptable. For that reason, OSHA recently started requiring the use of approved fall protection methods instead of these alternate methods. Approved fall protection methods for roofing projects would be a fall protection system (think fall arrest harness) with an anchor point on the roof or a netting system around the roof. If we performed a risk assessment with one of these controls, the risk would be reduced significantly to a point that most of us would say is acceptable. References Goetsch, D. L. (2019).
