The first step in the System Safety process is to define the objectives of the system under review. Risk Assessment is generally defined as the process of combining the impacts of risk elements discovered in risk analysis and comparing them against some acceptability criteria.
Validation and control begins with (1) the results of scheduled analyses on the effectiveness of actions taken (this will include identification of data to be collected and identification of triggering events if possible; then developing a plan to review the data collected) and (2) the current status of each prioritized risk. This is not the only way to do risk assessment as there are no fixed rules about how a risk assessment should be carried out. Your risk assessment should include consideration of what in your business might cause harm and how and, the people who might be affected. You should carry out an assessment before you do work which presents a risk of injury or ill health. Administrative Controls - These are all about identifying and implementing the procedures you need to work safely. You need to make sure that, based on the findings of the assessment, you take adequate and appropriate fire safety measures to minimise the risk of injury or loss of life in the event of a fire. Remember, the greater the risk the more robust and reliable the control measures will need to be.
There is no set amount of time that you need to keep your records relating to general risk assessment. The use of electricity has inherent risks, particularly electric shock and arc flash hazard.
The relationship between hazard and risk can often be summarized via a Risk Assessment Matrix as per figure 1, which provides an easily understood, defined approach to hazard analysis and risk assessment. Simply be using the Risk Assessment Matrix, the consulting engineer or business operator could have readily identified that choosing to specify a solidly grounded electrical system while economical and simple to implement, the associated hazard frequency level of OCCASIONAL and a hazard severity level of SERIOUS would result in a MEDIUM level of risk and that remedial action would need to be taken at the next convenient opportunity. High resistance grounding, as a technology, was originally applied to industrial power distribution systems in industries as diverse as: food processing, mining, petrochemical and even commercial installations such as airports, data centers, etc. If we deploy proven technology such as High Resistance Grounding to reduce the frequency of the ground fault and arc flash hazard to OCCASIONAL or REMOTE and we take steps to reduce the impact of the hazard through the use of current limiting fuses or fast action optical relays to MARGINAL or MINOR, if we isolate personnel from the Hazard through arc resistant switchgear or remote racking then we can achieve a LOW risk from Electrical Hazards. Risk Assessment can include the consolidation of risks into risk sets that can be jointly mitigated, combined, and then used in decision making. It is a legal requirement for every employer and self-employed person to make an assessment of the health and safety risks arising out of their work.
They will have useful information about how work is done which will help you understand the actual risks. However management tools and technology are readily available to mitigate and manage these risks. We can define the frequency as Occasional and thankfully the impact on personnel to be low as most ground faults simply result in process outages. If the hazard cannot be eliminated completely then there are a number of control options that can be used to prevent or minimize exposure to the risk. Neither affects the frequency or severity of the hazard and the consequential impact on equipment damage and process interruptions but both ensure a lower risk of injury to personnel. Prior to risk analysis you must also include the consequence (undesired event) resulting from the hazard scenarios.
The purpose of the assessment is to identify what needs to be done to control health and safety risks. There are estimated to be around 210,000 industrial facilities that operate solidly grounded despite the higher level of risk.


Generally, design engineering follows the “safety order of precedence”: 1) Design for minimum risk, 2) Incorporate safety devices, 3) Provide warning devices, or 4) Develop procedures and training.
Kits are quite common and injuries that do not improve process risk assessment matrix in two you will consist of in the hangover.
Save time with the pre-formatted template; fill-in the blanks and you’re ready to start your risk assessment! The objective of this assessment is to ensure that the overall risk to the organization and its operations is managed appropriately on an ongoing basis. If you want to easily and quickly perform a high quality threat and risk assessment , this template is your solution!
A description of the interactions among people, procedures, tools, materials, equipment, facilities, software, and the environment. If the status of a risk should change or the mitigating action does not produce the intended effect, a determination must be made as to why. Any paperwork that is produced should help with communicating and managing the risks in your business.
Remember that any paperwork that is produced should help with communicating and managing the risks in your business. Personal protective clothes and equipment - Only after all the previous measures have been tried and found ineffective in controlling risks to a reasonably practicable level, must personal protective equipment (PPE) be used. Significant risks are those that are not trivial in nature and are capable of creating a real risk to health and safety which any reasonable person would appreciate and would take steps to guard against. Risk is the chance, high or low, of somebody being harmed by the hazard, and how serious the harm could be. With the information available we can categorize the Risk Assessment of an electrical ground fault to be somewhere between HIGH and SERIOUS with financial damages according to one insurance company averaging $769,000 the majority of which is likely to be the costs associated with business interruptions and capital equipment damage.
In fact, since this was the design stage, preventative measure could have been implemented to ensure a REMOTE frequency and MARGINAL or MINOR impact to secure a LOW level of risk. It is a formal and flexible process that generally follows the steps in the FAA’s Safety Risk Management Order, 8040.4.
Review the list to determine how to address each risk, beginning with the highest prioritized risk. The fire safety assessment can be carried out either as a separate exercise or as part of a single risk assessment covering other health and safety risks. When you take on work or go to a new site, cover any new or different risks with a specific assessment. A hazard is something with the potential to cause harm and damages whether that be to equipment, processes or personnel.
If the insurance investigation determines that the root cause was the specifying of a solidly grounded system which by its very nature contains a risk of arc flash occurring, then the responsibility lies with the specifying engineer. Personal Protective Equipment should be used as a last resort when exposure to risk is not or cannot be minimized by other measures. A systematic approach to process improvement requires proactively searching for opportunities to improve the process at every step, not simply identifying deficiencies after an undesired event.
In either case, one would then re-enter the system safety process at the hazard identification step.
It includes all the risks identified in the risk assessment and the measures needed to control those risks. Risk is an expression of the impact of an undesired event in terms of event severity and event likelihood.


Step by careful step, word by word, paragraph by paragraph, and page by page, our template empowers you to effectively document and understand your business risks.
Listed in order of priority and aligned to the risk tolerance and objectives listed previously. Risk analysis is the process whereby hazards are characterized for their likelihood and severity. To do a risk assessment, you need to understand what, in your business, might cause harm to people and decide whether you are doing enough to prevent that harm.
Remember that you only need to record your risk assessment if you employ five or more people and any paperwork that is produced should help with communicating and managing the risks in your business. A risk assessment is simply a careful examination of what, in your work, could cause harm to people, so that you can weigh up whether you have enough precautions or whether you should do more. An arc flash would likely have a Risk Assessment of MEDIUM to SERIOUS due to its low frequency but devastating impact on equipment and personnel.
The question for engineers, business owners, safety managers etc is what steps to take next after defining and categorizing the Risk and Hazard. If the residual risk is acceptable, then documentation is required to reflect the modification to the system, and the rationale for accepting the residual risk. However, they can be used to help you work out the level of risk associated with a particular issue.
The remains damage to the capital equipment but less than in conventional switchgear, there remains process interruptions but perhaps less than in conventional switchgear but personnel are isolated from the hazard.
This provides an intermediate product that expresses the condition and the consequences that will be used during risk analysis. This means balancing the level of risk against the measures needed to control the real risk in terms of money, time or trouble. As an employer or self-employed person, you must do a risk assessment but you only need to record it if you employee five or more people.
Administration and the use of personal protective equipment are the lowest priority on the list of controls and should never be relied on as a primary means of risk control. However, we believe that the controlling the risks in the workplace guidance provides the most straightforward way for most businesses. It describes in a logical sequence exactly how a job is to be carried out in a safe manner and without risks to health. Throughout this process, hazards are identified, risks analyzed, assessed, prioritized, and results documented for decision-making.
Whether safety method statements are used or not, it is essential to make sure that risks are controlled. You do not need to include risks from everyday life unless your work activities increase the risk. For example, where you cannot eliminate the risk of a fall, use work equipment or other measures to minimise the distance and consequences of a fall (should one occur).
