Risk Matrix

Summary

A risk matrix is a tool used to assess the level of risk posed by various hazards on a fishing vessel, considering the likelihood of occurrence and potential consequence. The skipper determines likelihood based on factors like training, experience, environment, and equipment condition. The summary explains how the risk matrix combines likelihood and consequence to produce a risk rating used to prioritize hazards. It provides an example of electrocution risk, demonstrating how controls like training, inspection, protective equipment, and task elimination can reduce risk.

Q & A

What is a risk matrix used for?

A risk matrix is used to assess the level of risk to an identified hazard such as falling overboard or cutting oneself using a knife.

What two factors are considered when assessing risk level?

The two factors considered are 1) the likelihood of the hazard occurring, and 2) the probable consequence as a result of it occurring.

How does likelihood of an accident increase?

Likelihood increases with more frequent exposure, less training/experience, hazardous environments, fatigue, improper tools and equipment.

Who determines the likelihood and consequence rankings?

The boat owner or skipper determines the likelihood and consequence rankings to suit their boat and fishing operation.

What are the four risk levels denoted by color?

The four risk levels are: Green (Low), Blue (Moderate), Yellow (High), Red (Extreme).

What are some administrative controls the skipper introduced?

Administrative controls included safety inspection and tagging of electrical equipment, training on inspecting equipment, and policy for inspection before use.

How did RCDs impact the risk level?

RCDs reduced likelihood of electrocution but did not change the potential consequence of electrocution, so risk level remained high.

How does substitution help reduce risk?

Substituting a battery-powered grinder reduced the potential consequence and severity should electrocution occur.

What is the best way to eliminate a hazard completely?

Elimination by outsourcing the grinding task removed the risk entirely, making it the ultimate safety control.

What are the key takeaways from this training?

Key takeaways are understanding risk matrix components, assessing likelihood/consequence, applying controls to reduce risk, and eliminating hazards completely when possible.

😊 Understanding Risk Matrices

This paragraph provides an overview of risk matrices - their purpose, how they assess risk levels based on likelihood and consequence, and how the risk levels are visually depicted using colors. It discusses how likelihood is influenced by factors like training, environment, state of mind, tools/equipment. It notes that boat owners determine likelihood rankings and consequences for their vessels.

😀 Risk Matrix Example for a Fishing Boat

This paragraph provides a detailed example of using a risk matrix during the refit of a fishing boat. It analyzes the risk of electrocution when using a faulty grinder. It shows how introducing controls like training, inspection policies, RCDs, substitution and elimination systematically reduces the risk level from extreme to low.

Keywords

💡risk matrix

A risk matrix is a tool used to assess the level of risk associated with various hazards. In the video, it is used to determine the risk level of accidents like falling overboard or cutting oneself. The matrix evaluates the likelihood of the hazard occurring and the potential consequence. It assigns risk levels using colors - green is low risk, blue is moderate, yellow is high, and red is extreme.

💡likelihood

Likelihood refers to the probability or chance of a hazard occurring. The video explains how likelihood increases with frequency of exposure, is influenced by training/experience, environment, physical/psychological state, and condition of tools. A higher likelihood leads to higher risk.

💡consequence

Consequence is the potential outcome or impact of a hazard occurring. Consequences range from insignificant to catastrophic. More severe consequences lead to higher risk levels in the matrix. The video advises assessing consequences against a table for consistent ratings.

💡administrative controls

Administrative controls are safety policies and procedures that aim to reduce risk through training, inspections, safe work practices etc. In the example, the skipper implements administrative controls like grinder inspections and training to reduce likelihood of electrocution.

💡substitution

Substitution refers to replacing a hazardous material/process with a less hazardous option to reduce risk. In the video, the skipper substitutes the 240V grinder with a safer battery-powered version to reduce potential consequence of electrocution.

💡elimination

Elimination completely removes the hazard and is the best risk control option. The skipper eliminates the electrocution hazard by outsourcing the grinding task and removing the need for the crew to use the grinder.

💡hierarchy of controls

The video demonstrates the hierarchy of controls - an order of preference for managing risks. It shows how elimination is most effective, followed by substitution, engineering controls, administrative controls, and PPE.

💡risk assessment

Risk assessment is evaluating the level of risk in a particular situation, taking into account the likelihood, consequences, and existing controls. The skipper performs risk assessments at each stage for the electrocution hazard.

💡as low as reasonably practicable

Though risks may not be entirely eliminated, the goal is reducing them to as low as reasonably practicable using the hierarchy of controls. This is done through cost-benefit analysis of risk reduction measures.

💡safety culture

A strong safety culture is one where everyone takes responsibility for safety through their values, attitudes and behaviors. The skipper demonstrates this by taking multiple steps to ensure the deckhand's safety.

Highlights

A risk matrix assesses the level of risk to an identified hazard by determining the likelihood and consequence.

Likelihood increases with frequency of exposure and is influenced by training, knowledge, experience and environment.

Consequence ranges from insignificant to catastrophic and is determined by the boat owner against a consequence table.

An example shows how administrative controls, engineering controls, and substitution reduced the risk of electrocution from using a grinder.

Elimination by outsourcing the grinding task completely eliminated the electrocution risk.

Likelihood relates to the probability or chance of a hazard occurring.

Consequence relates to the impact or result should the hazard occur.

Risk level is typically color coded - green is low risk, red is extreme risk.

The boat owner determines likelihood and consequence rankings to personalize the risk matrix.

Administrative controls like training and inspection can reduce likelihood.

Engineering controls like RCDs can also reduce likelihood but not consequence.

Substitution can reduce the severity or consequence should the hazard occur.

Transcripts

hello and welcome to the risk matrix

training module a risk matrix is used to

assess the level of risk to an

identified hazard such as falling

overboard or cutting oneself using a

knife the level of risk is assessed by

one determining the likelihood of the

hazard occurring and to assessing the

probable consequence as a result of it

occurring the level of risk is typically

expressed by four colors green

represents low risk blue represents

moderate risk yellow represent high risk

and red represents extreme risk

in a risk matrix likelihood is the

probability or chance of a hazard

occurring and it increases with the

frequency of exposure to the hazard for

example the more times a deckhand uses a

240-volt grinder on the back deck the

greater the likelihood of electrocution

likelihood is also influenced by

training knowledge and experience for

example an experienced well-trained

deckhand may have less likelihood of

falling overboard than a newer green

deckhand because he or she knows the

movement of the boat and how to operate

safely on the deck the environment can

also influence the likelihood of an

accident for example the likelihood of

falling overboard is likely to increase

when working on the deck in gale force

winds compared to a day without wind the

likelihood of an accident may be further

increased by the person's physical and

psychological state for example a

fatigue deckhand is more likely to fall

overboard than a well-rested deckhand

however the physical and psychological

state of the person is not always easy

to determine

so consideration needs to be given to

the type amount and duration of their

work when considering the likelihood of

an accident

finally the likelihood of an accident

is influenced by the type and condition

of tools and equipment used to complete

a task for example old rope or chain is

more likely to part the new rope or

chain

in the risk matrix the likelihood of an

accident occurring ranges from rare to

certain as the boat owner or skipper is

responsible for the safety of all

onboard and the boat they are the ones

who determine the likelihood ranking for

a particular accident in this way the

matrix is personalized to suit the boat

and intended fishing operation the

consequence of a hazard ranges from

insignificant to catastrophic and it is

the boat owner or skipper who identifies

the consequence of a hazard

the consequence of a hazard should be

assessed against a consequence table

this table provides a guide to

consistent determination of the

consequence of a hazard occurring which

is then applied when using the risk

matrix for example the consequence of an

injury requiring hospital treatment

might be considered moderate while a

fatality is a major consequence

that was a lot of information so let's

put it all together in an example to see

how it works

consider this during refit of a fishing

boat deckhand Robert is required to use

a grinder to cut a piece of steel the

grinder he uses has afraid electrical

cord with exposed wiring with no other

safety controls in place it is likely

that Robert may be electrocuted using

the grinder and he could die as a result

of electrocution as such we can

calculate the risk level at red 21

extreme this is an unacceptable risk so

the skipper takes steps to protect

Robert first the skipper introduces

administrative controls this includes a

safety inspection and tagging of all

electrical equipment that is deemed safe

to operate this skipper provides Robert

training on inspecting electrical

equipment and introduces a policy that

Robert must inspect this equipment

before it is used let's see how this

affects the risk level the

administrative controls now reduce the

likelihood of electrocution when Robert

uses a grinder it does not eliminate the

risk entirely because if Robert was

electrocuted the consequence could still

be fatal

you can see how the likelihood of

electrocution was reduced but not the

consequence should it occur next the

skipper installs our CDs which

immediately switch off electricity

should there be a problem with the

circuit the likelihood of electrocution

is now reduced to rare but electrocution

and potential consequence is unchanged

risk rating remains high the skipper

then decides to substitute for a

battery-powered grinder now the

consequence of electrocution from a

battery is relatively minor hence the

severity is low we can see how

substitution can reduce the severity or

consequence should electrocution occur

this skipper has one final option to

eliminate the hazard by outsourcing the

grinding task to a professional now the

risk to Robert has been eliminated

demonstrating why elimination is the

ultimate safety control measure that

should be used whenever possible

congratulations we covered a lot of

information now let's review the

material covered
