1. Acceptability/Tolerability of Risk
There are criteria by which a society decides which risks it is prepared to expect workers and members of the public to live with, and those it is not. Risks may be classified into three categories: Acceptable - No further action required; risks insignificant or trivial and adequately controlled. They are of inherently low risk or can be readily controlled to a low level. Unacceptable - Certain risks cannot be justified (except in extraordinary circumstances) despite any benefits they might bring. Tolerable - Risks that fall between the acceptable and unacceptable.

2. Abuse, aggression, or violence incident
Abuse, aggression, or violence is defined as ‘an incident in which employees feel they have been verbally abused, threatened or attacked in circumstances relating to their duties either in or out of work’. Employees should report incidents involving race, gender or gender identity, religion or belief, disability, sexuality, and age in line with the requirements of the Council’s Dignity at Work Policy.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
3. People at the risk of violence
Those at increased risk are likely to be employees who:
• handle or collect money or valuables
• give advice or training
• work alone or away from a workplace
• carry out enforcement duties or inspections
• have contact with service users.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
4. Aggression
Aggression has potentially damaging effect on an employee’s well-being of all categories of violence - actual physical attack, the threat of violence, and verbal abuse.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
5. Bullying and harassment Definition
Bullying is usually seen as acts or verbal comments that could psychologically or 'mentally' hurt or isolate a person in the workplace. Sometimes, bullying can involve negative physical contact as well. Bullying usually involves repeated incidents or a pattern of behavior that is intended to intimidate, offend, degrade or humiliate a particular person or group of people. It has also been described as the assertion of power through aggression
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
6. Risk Assessment - Qualitative
No actual measurement is used. It involves describing the qualities, e.g. the airborne concentration was high or serious; the injury sustained was minor.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
7. Factors Affecting Probability and Severity of Risk
The likelihood or probability of the event occurring; and the consequence or harm realized if the event takes place. This is usually expressed as: Risk = Likelihood (or Probability) × Consequence (or Harm)
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
8. Tolerable - Risks
Tolerable - Risks that fall between the acceptable and unacceptable. Tolerability does not mean acceptable but means that society is prepared to endure such risks because of the benefits they give and because further risk reduction is grossly out of proportion in terms of time, cost, etc.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
9. Workplace violence and aggression
Workplace violence and aggression is when a person is abused, threatened or assaulted at the workplace or while they’re working. It can cause both physical and psychological harm, making it a risk to health and safety.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
10. types of violence
All types of violence are unacceptable. This includes:
Physical attack - whether the visible injury occurs or not
Animal attack - when an animal is used as a threat
Verbal abuse - when an employee feels threatened or intimidated and the abuse is personally directed. This also includes cyber-aggression through texts, email messages, or social networking sites
Attack or damage to property or belongings of the employee
Any work-related incident involving an employee, or their family, happens away from the workplace.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)

14. The Rules of Professional Conduct ().
The Rules of Conduct is a set of implementing laws of professional practice that seek to express the primary examples of ethical behavior consistent with the Code of Ethics
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
15. Workplace inspections.
A workplace inspection is the process of critically examining the workplace for the identification and mitigation of workplace hazards and to ensure that all standards are met and the workplace is in fact safe and free from any risks.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
16. Safety Tours
Safety tours are usually conducted by management or senior management as part of their commitment to workplace safety. It also provides managers and senior managers with up-to-date knowledge of workplace day-to-day activities, as well as an opportunity for them to connect directly with employees to improve team relations.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
17. Safety Sampling
The HSE defines safety sampling as the “systematic sampling of particular dangerous activities, processes or areas.” An example of safety sampling is taking a sample of the chemicals or gasses that employees work with or are exposed to, then conducting a lab analysis on the samples.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
18. Safety Surveys
Safety surveys are general inspections of specific dangerous activities, processes or areas. It is similar to a safety tour, but focuses on high-risk workplace environments or processes. Examples of typical areas to conduct safety surveys include a mining site, drilling rig, and a laboratory that screens for infectious diseases.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
19. Incident Inspections
Also known as emergency inspections, incident inspections are conducted after an incident caused a fatality, an injury, ill health, damage to property, or a near miss. These inspections are performed to identify the root cause so it can be mitigated to prevent similar incidents from happening again in the future.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
20. Incident Investigations
Monitor the effectiveness of the measures you put in place to control the risks in your workplace. As part of your monitoring, you should investigate incidents to ensure that corrective action is taken, learning is shared and any necessary improvements are put in place.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
21. Mean vs Median
Both are measures of where the center of a data set lies (called “Central Tendency” in stats), but they are usually different numbers. For example, take this list of numbers: 10, 10, 20, 40, 70. The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30. The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20. Sometimes the two will be the same number. For example, the data set 1, 2, 4, 6, 7 has a mean of 1 + 2 + 4 + 6 + 7 / 5 = 4 and a median (a middle) of 4
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
22. A Standard Deviation
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
23. Time Weighted Average
A time-weighted average is equal to the sum of the portion of each time period (as a decimal, such as 0.25 hour) multiplied by the levels of the substance or agent during the time period divided by the hours in the workday (usually 8 hours). The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30. The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20. Sometimes the two will be the same number. For example, the data set 1, 2, 4, 6, 7 has a mean of 1 + 2 + 4 + 6 + 7 / 5 = 4 and a median (a middle) of 4
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
24. What is a Percentage?
In mathematics, a percentage is a number or ratio that represents a fraction of 100. It is one of the ways to represent a dimensionless relationship between two numbers; other methods include ratios, fractions, and decimals. Percentages are often denoted by the symbol "%" written after the number.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
25. What is the Median?
The median is the middle number in a data set. To find the median, list your data points in ascending order and then find the middle number. The middle number in this set is 28 as there are 4 numbers below it and 4 numbers above:
23, 24, 26, 26, 28, 29, 30, 31, 33
Note: If you have an even set of numbers, average the middle two to find the median. For example, the median of this set of numbers is 28.5 (28 + 29 / 2):
23, 24, 26, 26, 28, 29, 30, 31, 33, 34
The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30.
The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.
Sometimes the two will be the same number. For example, the data set 1, 2, 4, 6, 7 has a mean of 1 + 2 + 4 + 6 + 7 / 5 = 4 and a median (a middle) of 4

![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
27. Risk Management Principles
Accept risks when benefits outweigh costs. Accept no unnecessary risk. Anticipate and manage risk by planning. Make risk decisions at the right level.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
28. Risk Assessments
Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. The results of this process may be expressed in a quantitative or qualitative fashion.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
29. The Risk Inventory
The risk inventory is done to create a checklist of potential risks to evaluate the likelihood of occurrence. Some organizations develop risk checklists based on past experiences. These checklists can be helpful in building a more comprehensive list.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
30. Risk Matrix
The risk matrix is based on two intersecting factors: the likelihood that the risk event will occur, and the potential impact that the risk event will have on the business. In other words, it's a tool that helps you visualize the probability vs. the severity of a potential risk.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
31. Prioritization
Risk prioritization is the process of identifying all the risks to a project and then deciding which ones are the most severe, so they can be addressed first. Prioritization should be based on the likelihood of a risk and the potential harm it poses to the organization.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
32. Precautionary Principle
The precautionary principle is a broad epistemological, philosophical and legal approach to innovations with potential for causing harm when extensive scientific knowledge on the matter is lacking. It emphasizes caution, pausing and review before leaping into new innovations that may prove disastrous.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
33. ALARA
ALARA stands for “as low as reasonably achievable”. ALARA means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)

67. What is the Globally Harmonized System (GHS)?
GHS stands for the Globally Harmonized System of Classification and Labelling of Chemicals. It is a system of hazard communication for chemical hazards that can be adopted by countries around the world. GHS was developed by a United Nations (UN) international team of hazard communication experts.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
68. SDS – Safety Data Sheet.
The GHS SDS has 16 sections in a set order, and minimum information is prescribed.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
69. Labels - With the GHS,
Labels - With the GHS, certain information will appear on the label. Standardized elements such as chemical identify, hazard statements, signal words and symbols will appear on the label according to the classification of that chemical or mixture. Precautionary statements may also be required, if adopted by your regulatory authority.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
70. Hazard group
Hazard group – While not given a formal definition, GHS divides hazards into three major groups – health, physical and environmental.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
71. GHS Hazard Class
Class – Class is the term used to describe the different types of hazards. For example, Gases under Pressure is an example of a class in the physical hazards group.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
72. GHS Category
– Category is the name used to describe the sub-sections of classes. For example, Self-Reactive Chemicals have 7 categories. Each category has rules or criteria to determine what chemicals are assigned to that category. Categories are assigned numbers (or letters) with category 1 (or A) being the most hazardous.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
73. GHS Hazard Statement
Hazard Statement – For each category of a class, a standardized statement is used to describe the hazard. For example, the hazard statement for chemicals which meet the criteria for the class Self-heating substances and mixtures, Category 1 is Self-heating; may catch fire. This hazard statement would appear both on the label and on the SDS.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
74. Precautionary Statement
Precautionary Statement – These statements are standardized phrases that describe the recommended steps to be taken to minimize or prevent adverse effects from exposure to or resulting from improper handling or storage of a hazardous product.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
75. GHS Signal word
Signal word – There are two signal words used by the GHS – Danger and Warning. These signal words are used to communicate the level of hazard on both the label and the SDS. The appropriate signal word to use is set out by the classification system. For example, the signal word for Self-heating substances and mixtures, Category 1 is Danger while Warning is used for the less serious Category 2. There are categories where no signal word is used.

130. Basic knowledge of Benzene
Benzene is a colourless, flammable liquid with a pleasant odour. It is used as a solvent in many areas of industries, such as rubber and shoe manufacturing, and in the production of other important substances such as styrene, phenol and cyclohexane. It is essential in the manufacture of detergents, pesticides, solvents and paint removers. It is present in fuels such as in gasoline up to the level of 5%. The Threshold Limit Value (TLV) in the workplace air over an 8- hour working day (as recommended in many countries) is 10 ppm (or 32 mg/m3). Some countries recommend even lower levels. The odour threshold is 12 ppm. The odour serves only as a warning of exposure. If you are handling benzene without smelling it, this does not mean that there is no exposure.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
131. Chemical hazards

![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
132. Difference between fumes and mists
Mist consists of fine drops of liquid (especially water drops) in the air. Fume are gaseous residues of combustion. Apart from gases and vapours smoke additionally contains solid matter in a very fine shape (often colloidal) such as soot, metal oxide particles or aerosols like drops of oil.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
133. Types of mist are there
There are several different types of fog, including radiation fog, advection fog, valley fog, and freezing fog. Radiation fog forms in the evening when heat absorbed by the Earth's surface during the day is radiated into the air. As heat is transferred from the ground to the air, water droplets form.

134. Acoustic barriers
Acoustic barriers are panels made of sound absorbing material which are placed between the source of noise and the worker. Panels must be designed appropriately (e.g., panels placed in highly reflective rooms are not always effective in attenuating the noise that reaches the worker).
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
135. Noise permissible exposure limit
OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker's time weighted average over an 8 hour day. With noise, OSHA's permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day.
![](https://p2safety.org/wp-content/uploads/2023/01/tap-150x150.png)
136. Enclosure and isolation
Noisy equipment can be enclosed in spaces or rooms that have special acoustic features – such as sound isolating, acoustic louvers, or sealed windows and doors. The degree of sound attenuation will depend on the noise reduction properties of the materials used to build the room. Isolation is used to reduce the sound transmitted through vibrations. The equipment is isolated from radiating surfaces by materials such as springs, elastomeric materials, cork, and foam rubber. For example: heavy vibrating machinery can be supported by isolating springs and rubber inserts, or vibrating pipes can be supported by brackets that are padded by rubber isolators or by springs.

236. What is the meaning of safety in design?
Safety in Design is a process that integrates hazard identification and risk assessment methods early in the design. The process considers how to eliminate, isolate or minimize the risks of death, injury and ill health to those who construct, operate, maintain, decommission or demolish an asset. Safe design applies to every stage in the life cycle from conception through to disposal. It involves eliminating hazards or minimizing risks as early in the life cycle as possible. The consistent application of hazard identification, risk assessment and risk control processes is required to achieve safe design.
