What is elimination control


Controlling exposures to occupational hazards is the elemental methodology of defending staff. Historically, a hierarchy of controls has been used as a method of figuring out tips on how to implement possible and efficient control options.

One illustration of this hierarchy is as follows:

What is elimination control

The thought behind this hierarchy is that the control strategies on the high of graphic are probably simpler and protecting than these on the backside. Following this hierarchy usually results in the implementation of inherently safer methods, the place the danger of sickness or damage has been considerably lowered.

NIOSH leads a nationwide initiative known as Prevention by Design (PtD) to forestall or scale back occupational accidents, sicknesses, and fatalities by the inclusion of prevention concerns in all designs that impression staff. Hierarchy of controls is a PtD technique. To be taught extra, go to the PtD web site.

Elimination and Substitution

Elimination and substitution, whereas simplest at lowering hazards, additionally are typically probably the most tough to implement in an present course of. If the method is nonetheless on the design or growth stage, elimination and substitution of hazards could also be cheap and easy to implement. For an present course of, main modifications in gear and procedures could also be required to eradicate or substitute for a hazard.

Engineering Controls

Engineering controls are favored over administrative and private protecting gear (PPE) for controlling present employee exposures within the office as a result of they’re designed to take away the hazard on the supply, earlier than it is available in contact with the employee. Effectively-designed engineering controls could be extremely efficient in defending staff and can usually be unbiased of employee interactions to offer this excessive degree of safety. The preliminary price of engineering controls could be greater than the price of administrative controls or PPE, however over the long run, working prices are continuously decrease, and in some situations, can present a value financial savings in different areas of the method.

For descriptions of engineering control applied sciences researched by NIOSH, and data on the control particulars and their effectiveness, go to our Engineering Controls Database. The engineering controls contained within the database are helpful for customers who want control options to scale back or eradicate employee exposures.

Administrative Controls and PPE

Administrative controls and PPE are continuously used with present processes the place hazards usually are not notably properly managed. Administrative controls and PPE applications could also be comparatively cheap to ascertain however, over the long run, could be very pricey to maintain. These strategies for shielding staff have additionally confirmed to be much less efficient than different measures, requiring vital effort by the affected staff.


What is elimination control

The hierarchy of hazard control has 5 ranges, with these on the high of the checklist being the best. They are often summarized as:

  • Get rid of the hazard
  • Substitute a much less hazardous materials or course of
  • Engineering controls
  • Administration controls
  • Private protecting gear

Get rid of the Hazard

There is no higher hazard control choice than eliminating the hazard. A generally used instance of eliminating a hazard is a state of affairs during which staff are working at a top above the bottom degree. Shifting the work to floor degree eliminates the autumn hazard.

Hazards could also be eradicated by altering how or the place the work is carried out. For instance, by eliminating a step the method that entails a hazardous materials. They could even be eradicated by redesigning a course of to eradicate the usage of hazardous gear, machines, instruments, or supplies.


Substitution is a type of hazard elimination, and the 2 could also be mixed on some hierarchy of hazard control lists. Substitution entails changing one thing that is hazardous, with one thing that is not hazardous. A typical instance is changing a solvent-based paint with a water-based paint. This eliminates the dangerous fumes and flammable vapors that outcome from utilizing, and cleansing up after utilizing a solvent-based paint.

Care should be taken to make sure a brand new hazard is not launched into the office when substituting one materials for one more.

Engineering Controls

When a hazard can’t be eliminated by elimination or substitution, the following best choice is to make use of engineering controls. On this case the hazard is not eradicated, however staff are protected against the hazard. The fundamental thought is to design the work atmosphere, and the work to be carried out, such that publicity to hazards is eradicated or lowered. For instance, if a machine has shifting elements, a guard could also be added to forestall bodily entry to the shifting elements.

Guarding shifting elements is also known as “enclosure and isolation.” Different examples of enclosure and isolation embrace:

  • Inserting MCCs in a separate room – separates staff from arc flash hazards.
  • Utilizing curtains round areas the place welding is going down – protects staff from the extreme gentle.
  • Inserting limitations round followers and different noisy gear – lowering sound ranges.
  • Fencing round electrical swap gear – prevents entry to excessive voltage gear.

Engineering controls are additionally used to take away a hazard. A typical instance of this is utilizing a fume hood to comprise and take away airborne hazards.

Administrative Controls

Administrative controls are used to direct folks to work in a protected method. They embrace procedures, warning indicators and labels, and coaching. Administrative controls don’t eradicate hazards, however prohibit entry to these hazards by the usage of procedures and guidelines.

OSHA divides all these controls into two classes, protected work practices and administrative controls. OSHA defines protected work practices as:

Protected work practices embrace your organization’s basic office guidelines and different operation-specific guidelines. For instance, even when a hazard is enclosed, publicity can happen when upkeep is obligatory. Via established protected work practices, worker publicity to hazards could be additional lowered.

OSHA considers administrative controls to be these different measures, aside from work practices, used to scale back worker publicity to hazards. This contains measures equivalent to further reduction staff, train breaks, and rotation of staff. The controls OSHA defines as “administrative controls” are usually used together with different controls that extra immediately stop or control publicity to the hazard.

Generally, administrative controls embrace:

  • Limiting the period of time somebody is uncovered to hazards.
  • Written working procedures.
  • Requirements for protected work practices.
  • Security and well being guidelines for workers.
  • Alarms, indicators, and labels.
  • Buddy system.
  • Coaching (and refresher coaching).
  • Stretching and warm-up workout routines
  • Break insurance policies.

Utilizing indicators and labels to warn about hazards is not solely a standard administrative control, it is required by OSHA. You possibly can be taught extra about OSHA compliance with our OSHA Security Indicators Information.

Private Protecting Gear

When no different choice is obtainable, private protecting gear (PPE) is used. This is the least efficient, and least fascinating, methodology of defending staff, and is thought of because the final line of protection towards hazards. If the PPE is broken or fails, the employee shall be uncovered to the hazard.

Frequent PPE contains:

  • Gloves
  • Exhausting hats
  • Security sneakers and boots
  • Security glasses/face shields
  • Excessive visibility clothes
  • Respirators


Realizing, understanding, and making use of the hierarchy of hazard control will lead to a safer office. All the time like to make use of the tactic that is highest on the checklist. Eliminating the hazard is at all times the best choice, and utilizing PPE the least fascinating choice.

What is elimination control

To control the hazards there are 4 ideas normally. Elimination of the best choice, if elimination is not attainable then substitution must be Engineering control is utilized to control hazards by engineering modifications within the course of. The final precept advocates the administrative control by making some administrative mechanism within the office to maintain away hazards from human and office.
The applying of all 4 control measures with the usage of private protecting equipments (PPEs) reduces the hazards considerably in office and out facet of the unit.


The best control measure is to control hazards on the supply by eliminating the hazard. Get rid of hazards on the “growth stage” it is vital to contemplate well being and security points when work processes are nonetheless within the planning phases. For instance, when buying machines, security must be the primary concern, not price. Machines ought to conform to nationwide security requirements — they need to be designed with the right guard on them to eradicate the hazard of a employee getting caught within the machine whereas utilizing it. Machines that aren’t produced with the correct guards on them could price much less to buy, however price extra when it comes to accidents, lack of manufacturing, compensation, and many others. Sadly, many used machines that don’t meet security requirements are exported to growing international locations, inflicting staff to pay the value with accidents, listening to loss from noise, and many others.

For these unfamiliar with the hierarchy of controls, a tiered strategy to fixing issues might sound alien. Even for the initiated, some points of the hierarchy could be complicated. So, somewhat than simply let you know what the hierarchy is at face worth, let’s take a extra in-depth take a look at every degree, beginning with two of the simpler ideas: elimination and substitution.


The idea of elimination is simple, as a result of it’s so simple as it sounds. Take the hazard that your staff face and eradicate it. The issue with elimination is that if the implementation of it was so simple as it sounds, all people can be doing it, wouldn’t they? Any firm would select to eradicate the prospect of their staff getting harm. And, if Elimination is obtainable to an employer, it is the choice they have to select. Keep in mind, the employer has an obligation to offer a office freed from hazards to their staff. If the employer is ready to try this, however chooses to not, they could possibly be a willful violation, ought to an OSHA inspection happen (to not point out worker accidents and fatalities which may happen resulting from your failure to take away the hazard).

If we’re speaking about elimination when it comes to gear or supplies, equivalent to eradicating some flammable fuel containers from an space the place sizzling work is being carried out or eliminating an pointless blade on a machine, the answer must be 100% efficient, so long as there isn’t a communication breakdown that permits any individual else to reintroduce the hazard again into the office or course of.


Once more, this is just about what it feels like. With substitution, we’re figuring out a hazardous substance or piece of apparatus and substituting it for a substance or piece of apparatus that is not hazardous. As an example, as an alternative of a solvent-based paint, use a water-based paint. As a substitute of sand-blasting, use a non-silica containing abrasive materials. If an alternate product exists in the marketplace, substitution is usually a very efficient resolution.

Besides, there’s a purpose why the hazardous variations nonetheless exist. If the substitutions have been good, they’d pressure the hazardous substances off the market. So why don’t they? Effectively, the downfalls of substitutions are inclined to often be high quality and price. Let’s take the paint instance. Paint was once nearly solely solvent primarily based, however solvent primarily based paints are excessive in VOCs (unstable natural compounds). Over time, as VOCs have been required to be lowered in solvent-based paints, different paints got here in the marketplace, equivalent to water-based. Early on, the standard of water-based paints was inferior to solvent primarily based, so some firms most likely continued to stay with the solvent-based to make sure a greater job. Sadly, one thing like that leaves a stigma and many individuals most likely nonetheless consider to this present day that solvent-based paints are superior even if with present expertise, many water-based paints usually are not solely equal to solvent-based however superior to.

No matter high quality, although, price can nonetheless be prohibitive. Oftentimes, the manufacturing of an artificial materials prices greater than the acquisition of a pure one, demand for the much less hazardous model drives up its price, or another variety of causes that make the options dearer. It’s this trade’s equal of why a grilled rooster salad prices $9.99 and a burger prices $5. Cheaper often doesn’t imply higher for you.

The opposite downfall to substitution is simply because a fabric doesn’t pose the similar hazard because the one you’re changing, doesn’t imply it doesn’t pose a hazard in any respect. An employer must do the required analysis to make sure that they aren’t changing one hazard with one other.

Elimination and substitution usually are not solely nice methods to abate hazards, however should be your most well-liked method. In different phrases, engineering controls, administrative controls, and PPE shouldn’t even come into the dialogue till elimination and substitution have been dominated out (besides within the case the place PPE use is required always, like a 100% security glasses coverage). Take the time to take a look at among the options your organization has give you for the hazards in your office. Are there conditions the place elimination or substitution may have been used? It’s possible you’ll be shocked how typically your reply is “Sure.”

After you’ve carried out that, maintain your eyes open and are available again for our subsequent article which can talk about what is meant by “engineering controls”.
