Dictionary of Occupational Titles versus Rodeo Clown

They are rodeo clowns but the DOT calls them rodeo performers. However, these two clowns aren’t the same. The one in the barrel is a barrelman while the clown to the right is a bullfighter.

What Do the DOT and O*Net Tell Us About Job Demands

We’ve mentioned that when an FCE is performed and the provided job description does not outline essential minimum physical or postural demands that the evaluating therapist must use the Dictionary of Occupational Titles to determine a work level category for comparison.  The Dictionary of Occupational Titles (DOT) was a publication of the United States Department of Labor and contained information on over 13,000 job titles.  The DOT provides a basic list of task functions that may be performed within a job title as well as placing each job title entry into a work level category (sedentary, light, medium, heavy, and very heavy).  The last version of the DOT was published in 1999.  For most purposes, the DOT was replaced by O*NET (Occupational Information Network) which provides information collected by incumbent employees and uses a different method for grouping and defining job titles.  One important difference – and the main reason that FCE providers refer to the DOT today – is that O*NET does not include a physical work level category for each job title. 

What Does The DOT Tell Us About Rodeo Clowns?

All too often, job titles in the DOT get lumped into a closest possible job title instead of a singular, job specific title.  In many ways, this dictionary is like a thesaurus when it comes to finding a specific job entry to use as a reference.  Due to the fact that a wide range of applicable job titles may all fall under one specific entry, the information is not always as applicable as we would like it to be.  Sometimes, it gets the main theme of the job but the demands may be off – or in other cases, the listed physical demand is more of an average of the possible demands.

Not too long ago, I went to a Cowtown Rodeo in southern New Jersey and was wondering how the Dictionary of Occupational Titles would define the demands for a rodeo clown.  Rodeo clowns fill a unique role within the world of rodeo.  At first glance, they seem to be for entertainment and they do fill that role.  However, one type of rodeo clown – the barrelmen – provides the comic relief while the other type of rodeo clown – the bullfighters – help to keep the riders safe when they have fallen off of a bull or a bronco.  From observation, it appears that rodeo clowns have to be fast, be agile, have good balance, and an ability to climb fences at times to get out of the way of a bull or bronco.  They don’t appear to have the heavy lifting demands of rodeo performers involved in calf roping which requires the ability to pick up a calf and put them back on the ground.

A Google search of rodeo clown and Dictionary of Occupational Titles leads to an entry for rodeo performer (after a little digging).    The entry explains the position of rodeo performer as:

“Demonstrates daring and skill by bronco riding, calf roping, bull riding, steer wrestling, or similar feats in rodeo competition to entertain spectators and compete for prize money.”

It really only covers the rodeo clown in the entertaining spectators portion as the rodeo clowns don’t perform the other tasks listed.  And the entry for clown in the DOT does not really seem to cover what a rodeo clown does, other than:

“Dresses in comical costume and makeup and performs original or stock comedy routines to entertain audience.”

There is a huge variation in the physical demands between the two entries.  The clown entry places the physical demand as light (20 pounds occasional, 10 pounds frequent, negligible constant) while the rodeo performer entry places the demand at heavy (100 pounds occasional, 50 pounds frequent, 20 pounds constant)

Once could argue that the rodeo clown fits closer to the rodeo performer description at heavy as they may have to help an injured rider up from the ground but DOT entries don’t do a good job of explaining the balance required or describing the surface that the rodeo clowns perform on (a dirt surface that has been churned up by the hooves of horses and cattle) or the need to be able to move quickly out of a need for safety for themselves and others.  However, the entry doesn’t explain to a person that hasn’t seen a rodeo clown in action that they may have to sprint to the edge of the arena and quickly climb the fence that separates the audience from the arena to get to safety.  Alternatively, the entry for rodeo performer is a little on the light side for use with rodeo riders that perform calf roping – a calf in a competition can weigh between 220 and 280 pounds per competition rules. Being that the roper is trying to get the calf roped, secure, and immobilized they are more likely than not to exceed 100 pounds of force in pushing, pulling, lifting, and carrying.

Rodeo clown runs away (quickly) from a bull.


Ideally, a job description for a job title when being used for comparison during an FCE will include information about the physical demands (lifting, pushing, pulling, carrying and the heights and manners that these tasks are performed) as well as the postural demands (balance, walking, kneeling, squatting, reaching, etc. and how they are performed/where they are performed).  Rodeo clowns definitely walk (and run) on uneven terrain that sometimes may be wet or muddy and is definitely slippery – balance and speed of movement for safety is definitely important.  Some rodeo performers need to have enough balance to stand on a horse while going around the arena at speed. Their climbing needs are not the usual climbing needs for your standard party or circus clown.  As a matter of fact, most jobs don’t require you to climb a 6 to 8 foot fence to escape from a rampaging bull.

A rodeo performer demonstrates significant balance while flying the flag. This is not your every day balance related work task.

Upcoming

In upcoming posts, we will take a look at other job titles to see how well the Dictionary of Occupational Titles matches up against the actual demands of the job. Posts will look at nursing, skilled trades, and many other jobs including a comparison for the personnel that work in Weights and Measures. Some positions, such as nursing, present many of the same issues outlined in this post. The entry for nurse in the Dictionary of Occupational Titles lumps almost all of the varied roles that nurses perform into one singular entry – however, some occupations such as police and fire have breakdowns of the different internal roles. We will visit each of these and look at the impacts that these entries may have on performance of an FCE.

The Devil Is In The Details

Yesterday, I had pulled a job description that had been provided to us for a Functional Capacity Evaluation to use as a resource during a discussion with a client as they sought to understand the dynamics of a particular job position within the security field. As I reviewed the description, I remembered that despite the description’s length and detail level, the description had some significant issues when it came to the issue of lifting and carrying.

Hidden Information On What May Be Carried


One piece of information that needs to be kept in mind is a small quote embedded in description box located two pages prior to the physical demands. The box that can be easily missed states: “Personal gear per individual carried routinely is about 28 pounds and may need to climb towers as high as 60 feet with about 21 pounds of gear (rifles are normally staged for towers).” A box just below that indicates that this gear includes weapons, binoculars and/or night vision equipment, special purposed detectors, ballistic helmet, ballistic vest, ammunition, flashlight, and other small items.

One of the issues is not the fact that the two tables don’t match due to the “21-24 pounds” in the carry section versus “11-24 pounds” in the lift section. That is a typo that can be easily clarified through a quick call to the employer (note to FCE providers: never be afraid to call the case manager to ask to reach out the employer for clarification of demands – even for typos.)

There are three issues in regards to the carrying and lifting tables within the job description:

Issues With Carrying

The first issue is that the carry demand is not clearly defined. As noted above, there is a small box that denotes “personal gear individually carried routinely is about 28 pounds”. Those items in the list are not carried in the traditional sense of a bimanual or unilateral carry. The items listed in that box are items that are either worn directly on the body (ballistic helmet, ballistic vest, handgun in a holster, etc.) or items that would be carried in pouches or attached to their belt or vest (ammunition, flashlight, radio, etc.).

That knowledge helps to potentially explain the 12 hours per day of carrying 25-34 pounds in the above table but the table does not include an explanation that would indicate that this is the case. It does not help to explain any of the values greater or less than that specific range. Loaded rifles typically weight below 10 pounds (as do radios, binoculars, night vision optics, sensors, and many other items) yet the 10 pounds and under range is marked as “NA” or not applicable.

The 35-50 pound range and the 51-74 pound range have less frequent demands but it is difficult to determine whether those categories are inclusive of the 28 pounds of gear carried on the security officer or those are different items that are to be carried in some manner.

The carrying section should include more descriptive information to inform the reader as to what is being carried as well as the object’s weight and the manner in which it is carried (with two hands, with one hand, or worn/attached to the body).

Issues With Lifting

The lifting section brings its own issues – partially due to the ambiguity of the section defining the carry demands as well as ambiguity within the lifting section.

A quick look at the lifting demands indicates occasional lifting within the 11-24 pound and 25-34 pound ranges with no lifting demands above 34 pounds. There are no lifting demands above 34 pounds yet the carrying section indicates carrying loads up to 74 pounds. Typically, in order to carry an object that object must first be lifted – unless it is being directly loaded onto a person by someone else (such as lifting a backpack for another individual to don).

As with the carrying section, the lifting section does not provide any definitions, beyond weight ranges, of what the security officer actually lifts during the performance of their job role. While the section we discussed at the beginning lists some of the gear for the position, it is difficult to apply those items to the lifting table.

While we can make assumptions that items that are carried are either carried with both hands, carried with one hand, or carried by wearing, it is difficult to make assumptions from this table about how the lifting is performed. In addition, the table does not indicate the height ranges that lifts are performed from (knee height, waist height, shoulder height, overhead). This is an important issue when performing post-offer physical abilities testing or when performing a return to work or fit for duty FCE to determine whether an employee qualifies for return to work at full duty.

The lack of details in both the carrying and lifting sections also make it difficult to determine if accommodations are available for modified duty or not.

What About Pushing And Pulling?

Carrying and lifting are two of the three big strength tasks that should be included in a job description. We haven’t discussed pushing and pulling and the tables above don’t include either. Over the course of the primary five pages of the job description, the words pushing and pulling were not present while some of the simple grasping tasks listed (opening doors, gates, hatches, etc.) have frequency values but not force values listed.

However, the physical abilities battery that all candidates must complete includes a requirement of completing a specified number of push/pull cycles of “41 PSI” and a single 6 inch push that is set at “91 PSI”. There is not any documentation within the job description or the test that can be tied directly to these values.

The Climbing Section Is Good

The section that deals with climbing tasks is much better and denotes the types of climbing that may be performed. One of the positive aspects of this section of the description is that it includes stairs as a form of climbing. I have read too many job descriptions in the past that indicate that the job title does not require the ability to climb yet the employee was injured while ascending or descending a flight of stairs.

The one detail that would be helpful is a better description of ladder types. In the past, we have performed onsite ergonomic assessments for generation of customized job descriptions which included multiple types of ladders for the same site including A-frame ladders, extension ladders up to 40 feet, and fixed ladders – both angled and vertical.

Summary

While this job description provides a significant level of detail, it does not include the details that a treating physician, treating physical therapist, or a therapist providing a return to work evaluation would need to successfully prepare an injured employee for return to full duty. These professionals need to know what is being carried, how it is being carried, what is being lifted and where it is being lifted from or to, and how the security officer is outfitted while performing their daily tasks. Pushing and pulling demands need to be better defined – from opening and closing doors, gates, and hatches to other tasks that may require pushing and pulling actions.

Often, when you ask an individual (therapists and physicians included) to describe a security officer, they will respond with a description of a generic security officer that one would meet in a shopping mall or at a concert/sports event. In the case of this job description for security officer, the position is much closer to a paramilitary role and security officers in this role need to treated/rehabbed in that manner.

This job description was heavy on words and tables and would have greatly benefitted from the addition of photographs that help to visually describe and define the actions performed by those in this job title as well as the environments in which the tasks are performed.

It’s Not Just About Being Clean and Nice Looking

It’s not about being messy or being neat – although one of these looks a lot better when the customers walk up.

storing wood

It’s about putting items at optimal heights for when a customer or an employee has to lift the items. Notice that the firewood on the right is stacked on not one but two pallets. This helps bring the bags of firewood to a more optimal initial lift position than trying to pick the firewood up off of the ground.

The power zone for lifting starts at just above knee height, which is about where the handle is located on the lowermost bundles of firewood in the image on the right.  Without those two pallets as a base, the firewood would be picked up from a less than optimal height (although, with some bending at the knees we can make it a much better and safer lift).

The firewood in the image to the left has two problems.  The first is that the lower levels of firewood are stored on the ground in bags that tend to spread in a horizontal fashion, reducing the overall height of the bag.  The second is that these bags don’t have regular handles on the top which can mean that the handle is actually on the level of the ground.  The use of a spare pallet or two and some reorganizing of the bags so that they stand with the handle portion of the bag in a vertical orientation could make this “retail display” a little easier on the backs of the employees and the customers.

He et al. look at using Google Glass to monitor eye blinking in drivers to determine signs of drowsiness.  Distracted driving is something that we’ve hit upon in other posts.  Technology such as this may be able to go along way in helping drivers to recognize when they are too fatigued to drive safely.

Schmidt et al. investigated a different way of dealing with fatigue during long drives through the use of a cooling device to help improve alertness.

Armstrong et al. reviewed the impact of two paramedic services transitioning to a powered stretcher to help reduce injuries related to patient transport.  This appears to be a cost-effective solution with a reduction in injuries during patient transport.

Hlavenka et al. investigated the effect of neck posture during lifting tasks on both lumbar spine posture and activation of trunk musculature.  They indicate that a retracted neck posture may help to lower the risk of pain and injury during lifting tasks.

A lot of money and time has been put into exoskeletons for assisting soldiers, laborers, and individuals who have had strokes or spinal cord injuries.  This is an area that I plan on revisiting in future posts.  For now, a company called suitX has introduced a modular line of exoskeletons for assisting with specific work related tasks and body parts.

Not so much ergonomics but a question of productivity and efficiency on the Monday after the Super Bowl.  Kraft Foods is suggesting the day after should be a holiday  with an anticipated 16.5 million workers may call out sick to recover from festivities the day before.  This is an interesting question when talking about presenteeism vs. absenteeism.  How much work is actually lost with people discussing the game and the commercials when they come to work the next day?

When I was taking a tour of our local police department with my son’s Cub Scout den, my son asked the officer who gave the tour about a poster in the squad room.  The poster had a police cruiser that had been in an accident and had a slogan reminding officers that car accidents cause more line of duty deaths than some of the other more media noticed causes.  I found this article with 5 real world tips that police officers can use to make their vehicle safer for today’s tour of duty.
