What are Control Measures? – Control measures include actions that can be taken to reduce the potential of exposure to the hazard, or the control measure could be to remove the hazard or to reduce the likelihood of the risk of the exposure to that hazard being realised. A simple control measure would be the secure guarding of moving parts of machinery eliminating the potential for contact.
| 1. Eliminate the hazard | Elimination of the hazard is not always achievable though it does totally remove the hazard and thereby eliminates the risk of exposure. An example of this would be that petrol station attendants in Ireland are no longer exposed to the risk of chronic lead poisoning following the removal of lead from petrol products sold at forecourts. |
| 2. Substitute the hazard with a lesser risk | Substituting the hazard may not remove all of the hazards associated with the process or activity and may introduce different hazards but the overall harm or health effects will be lessened. In laboratory research, toluene is now often used as a substitute for benzene. The solvent-properties of the two are similar but toluene is less toxic and is not categorised as a carcinogen although toluene can cause severe neurological harm. |
| 3. Isolate the hazard | Isolating the hazard is achieved by restricting access to plant and equipment or in the case of substances locking them away under strict controls. When using certain chemicals then a fume cupboard can isolate the hazard from the person, similarly placing noisy equipment in a non-accessible enclosure or room isolates the hazard from the person(s). |
| 4. Use engineering controls | Engineering Controls involve redesigning a process to place a barrier between the person and the hazard or remove the hazard from the person, such as machinery guarding, proximity guarding, extraction systems or removing the operator to a remote location away from the hazard. |
| 5. Use administrative controls | Administrative controls include adopting standard operating procedures or safe work practices or providing appropriate training, instruction or information to reduce the potential for harm and/or adverse health effects to person(s). Isolation and permit to work procedures are examples of administrative controls. |
| 6. Use personal protective equipment | Personal protective equipment (PPE) include gloves, glasses, earmuffs, aprons, safety footwear, dust masks which are designed to reduce exposure to the hazard. PPE is usually seen as the last line of defence and is usually used in conjunction with one or more of the other control measures. An example of the weakness of this control measure is that it is widely recognised that single-use dust masks cannot consistently achieve and maintain an effective facepiece-to-face seal, and cannot be adequately fit-tested and do not offer much, if any real protection against small particulates and may lead to a false sense of security and increase risk. In such instances an extraction system with fitted respirators may be preferable where the hazard may have significant health effects from low levels of exposure such as using isocyante containing chemicals. |

What are controlling measures?
What are Control Measures? – Control measures are the protective precautions put into place to protect individuals from the risks and hazards that exist within the workplace. Therefore, control measures are an essential part of risk assessments within organisations. Knowledge and training of all types of control measures is essential.
What is an example of control measure?
What are control measures in risk assessment? – Control measures are the things you put in place to reduce risk and prevent harm. Control measures may include one or a mixture of:
Removal Rules Procedures Equipment Exclusions Training Supervision Limitations Preventions Methods Arrangements
There are lots of control measures available. If you tell your team to carry out a task wearing goggles to protect their eyes, that’s a control measure. If you send staff on a training course to understand how to do something safely, that’s a control measure.
- If you provide an item of equipment that makes the task safer, that’s also a control measure.
- Elimination is the best control measure you can use, to eliminate the risk from the task entirely.
- Of course, this is the best control measure, because you are removing the risk entirely.
- No risk, no danger, no chance of harm! Now we know the best control measure, can you use this control for every risk and be the safest business in the world? Unfortunately, it doesn’t quite work like that.
While in theory, it may be possible to eliminate every risk. In practice, this would mean you and your team sitting in a padded room, away from any tools or equipment and not getting any work done. Great for safety, but not so great for your business. What elimination is actually about, is eliminating those risks that are unnecessary.
For example, working at height creates a high level of risk, so if instead, you can do the work from ground level (e.g. using extendable poles or raising and lowering equipment) then you have eliminated the risk of working at height. What about when you can’t eliminate a risk? What if the work has to get done at roof height and there is no getting around it.
Enter, the hierarchy of risk control, The hierarchy of controls is simply a list of the best control measures, in order of priority. For example, item number 1 in the list (which should now be no surprise, it’s elimination) is the best and should be considered first before moving to item number 2.
What are the different types of safety controls?
They are arranged from the most to least effective and include elimination, substitution, engineering controls, administrative controls and personal protective equipment. Often, you’ll need to combine control methods to best protect workers.
What are the five 5 measures of risk?
Key Takeaways –
Risk measures are statistical measures that are historical predictors of investment risk and volatility.Risk measures are also major components in modern portfolio theory (MPT), a standard financial methodology for assessing investment performance.The five principal risk measures include the alpha, beta, R-squared, standard deviation, and Sharpe ratio.
What are the two types of control measures?
Goal of the Module This Module provides trainees with information on various methods that can be used to control workplace hazards. Topics discussed include: eliminating hazards, substitution, engineering controls, administrative controls, personal protective equipment, how to choose control measures, and the role of the health and safety representative in using control methods to reduce occupational hazards.
| At the end of this Module, trainees will be able to: (1) describe at least three methods of control; (2) suggest several methods of preventing and controlling hazards in their own workplaces. |
What is in this Module I. Introduction All workplace hazards (chemical, physical, etc.) can be controlled by a variety of methods. The goal of controlling hazards is to prevent workers from being exposed to occupational hazards, Some methods of hazard control are more efficient than others, but a combination of methods usually provides a safer workplace than relying on only one method.
Some methods of control are cheaper than others but may not provide the most effective way to reduce exposures. The most effective method of controlling hazards is to control at the source by eliminating the hazard or by substituting a hazardous agent or work process with a less dangerous one. Before thinking about what control measures are needed, first you need to know whether there are health and safety problems in your workplace, and if so, what they are.
How can you identify health and safety problems? Here are some of the ways you can identify health and safety problems:
- observe your workplace;
- investigate complaints from workers;
- examine accident and near-miss records;
- examine sickness figures;
- use simple surveys to ask your co-workers about their health and safety concerns;
- use check-lists to help you inspect your workplace;
- learn the results of inspections that are done by the employer, the union or anyone else;
- read reports or other information about your workplace.
Once you recognize a hazard, then you can determine which measure will correct the problem most effectively. Generally, there are five major categories of control measures: elimination, substitution, engineering controls, administrative controls and personal protective equipment.
Eliminating a hazard means removing it completely; substitution is replacing one hazardous agent or work process with a less dangerous one. An engineering control may mean changing a piece of machinery (for example, using proper machine guards) or a work process to reduce exposure to a hazard; working a limited number of hours in a hazardous area is an example of an administrative control (for example, job rotation); and personal protective equipment (PPE) includes ear and eye protection, respirators, and protective clothing.
Remember : it is always better to control the hazard as close to the source as possible. Using personal protection is the least acceptable and least effective of all control measures.

II. Methods of control A. Elimination Elimination of a specific hazard or hazardous work process, or preventing it from entering the workplace, is the most effective method of control. Eliminate hazards at the “development stage” It is important to consider worker health and safety when work processes are still in the planning stages.
For example, when purchasing machines, safety should be the first concern, not cost. Machines should conform to national safety standards — they should be designed with the correct guard on them to eliminate the danger of a worker getting caught in the machine while using it. Machines that are not produced with the proper guards on them may cost less to purchase, but cost more in terms of accidents, loss of production, compensation, etc.

Unfortunately, many used machines that do not meet safety standards are exported to developing countries, causing workers to pay the price with accidents, hearing loss from noise, etc.

Eliminating a specific hazard is the most effective method of control. It is easier to eliminate hazards while a work process is still in the development stages. |

What are the types of control with example?
Proactivity
| Control Proactivity | Behavioral control | Outcome control |
|---|---|---|
| Concurrent control | Hands-on management supervision during a project | The real-time speed of a production line |
| Feedback control | Qualitative measures of customer satisfaction | Financial measures such as profitability, sales growth |
What is an example of a control process?
Feedback – Feedback occurs after an activity or process is completed. It is reactive. For example, feedback control would involve evaluating a team’s progress by comparing the production standard to the actual production output. If the standard or goal is met, production continues.
If not, adjustments can be made to the process or to the standard. An example of feedback control is when a sales goal is set, the sales team works to reach that goal for three months, and at the end of the three-month period, managers review the results and determine whether the sales goal was achieved.
As part of the process, managers may also implement changes if the goal is not achieved. Three months after the changes are implemented, managers will review the new results to see whether the goal was achieved. The disadvantage of feedback control is that modifications can be made only after a process has already been completed or an action has taken place.
Is a safety data sheet a control measure?
Safety Data Sheets and Employers – The employer, or competent person who has been delegated the duty of carrying out the risk assessment, needs to consider the important information in the safety data sheet alongside specific details of their organisation.
- This includes how the chemical will be used, where it’ll be used, and who will use it in their business.
- For example, they should consult the information about how the chemical should be stored, then assess if there is a suitable location on their premises.
- Likewise, they should look at the hazards that the chemical poses, consider who will be using them, and then determine how to protect those people from the hazards.
This may include engineering controls like local exhaust ventilation to remove fumes from the air, for instance. The measures required after reviewing the safety data sheet depend on the specific circumstances of the business and how the product is used. This is why it’s so important to not consider it a substitute for risk assessment. All the information that is relevant to the particular use or production of the substance should be taken from the safety data sheet and added to the risk assessment.
What is an example of a safety control?
Example: Respiratory Protection – Failure to follow respiratory protection standards causes hundreds of deaths and thousands of illnesses each year, according to OSHA, Respirators are a key part of these standards. But if you can use other safety controls, too, you’ll be better protected.
Elimination: Remove asbestos ceiling tiles from old buildings. Substitution: Choose chemicals and materials that are less harmful. Engineering controls: Install a ventilation system in your facility. Administrative controls: Reduce the number of people present when a process will produce dust or a vapor. Personal protective equipment: Have workers wear respirators to purify the air they breathe and filter out contaminants.
Read OSHA’s Respiratory Protection Standard for detailed guidelines for your industry.
Is PPE the first level of control?
5. Personal Protective Equipment (PPE) – Personal protective equipment (PPE) is the fifth level of control and is the least effective method of controlling a hazard. PPE should only be used as the last line of defense and when other methods of control are not possible or effective. PPE Example: PPE includes clothing, gloves, and other items that protect the body from exposure to a hazard.
What are the six 6 methods of controls?
Here we review six main ways of achieving control: personal controls, bureaucratic controls, output controls, cultural controls, control through incentives, and market controls.
What is the best method of control?
Condoms + Birth Control = Extra Protection – Condoms are your safer sex superhero: they’re the only way to get protection from pregnancy and STDs during vaginal sex. No birth control method is perfect. So using condoms with another type of birth control (like the implant, IUD, or pill ) gives you backup protection in case either method fails.
And condoms seriously lower your chances of getting all kinds of sexually transmitted infections, like HIV, gonorrhea, chlamydia, and herpes, Another great thing about condoms is that you can get them almost anywhere, like drugstores, grocery stores, convenience stores, and gas stations. Condoms don’t cost a lot of money, and sometimes they’re even free at community clinics, school health centers, or Planned Parenthood health centers,
