Example 1
Consider two different CC Acts as examples. In past articles, we have considered the act of climbing using 3 points of contact.
What is/are the Objective(s) of the CC? This Objective of the Act is to have a person climbing equipment or structure protected from falling a distance that could lead to a fatality or permanent disability by requiring the person to have three points of contact while climbing that is secure and stable.
What are the Performance Requirements of the CC to meet the Objective(s)?
- Act expectation defined – The requirement to climb using 3 points of contact and the situations where is a requirement are clearly documented.
- Knowledge acquired – Training for all relevant personnel is in place to introduce the Act requirements and the relevant situations for its’ application. Assessment to ensure understanding is part of the training.
- Personnel selected – Tasks where climbing equipment or structure is required are only done by those who have had successful training.
- Pre-task requirement communicated – Pre-task or pre-shift briefing where the tasks may include climbing equipment or structure involve reinforcement of climbing using 3 points of contact by the briefing leader.
- Erosion factors minimised – Erosion factors such as the need to carry materials / items when climbing, as well as the provision of secure climbing hand and foot holds on all relevant equipment and structures should be examined and actions clearly undertaken to address these or any other erosion factors that may compromise adherence to the requirement.
What are the important data types to verify Performance Requirements?
All 5 areas are relevant but areas 2, 4 and 5 are likely the most important for verification. The climbing using 3 points of contact Act is not complex, but training (2) is important to ensure all understand the situation where it is relevant – such as a height or fall exposure criteria. Timely reinforcement (4) in pre-task briefing before relevant tasks helps reduce errors related to mistakes. Area 5 is very important at all sites where climbing locations, surfaces, hand/foot etc holds may be inadequate.
What questions need to be answered to verify the status of the CC?
Recognizing the aforementioned most important areas, the following questions are suggested.
- Have the Acts knowledge requirements been defined?
- Are they included in quality training?
- Is the knowledge assessed?
- Are there pre-task briefings for tasks where the Act may be relevant?
- Is the requirement for the Act reinforced at the pre-task briefings?
- Have the significant erosion factors for the Act been identified?
- Are there initiatives to reduce these factors?
- Are the initiatives in place and effective?
What sources of existing or new data sources can provide answers to the questions?
The site can identify the sources of information that will answer the questions. Some will involve reviewing documentation and systems information, while other will involve observation. For example, a, b, c, f, and g would involve finding and reviewing documentation that answers the questions satisfactorily. Questions d and e would involve observation of task briefings.
What frequency of data gathering is needed to consider effectiveness in a timely manner?
Documentation review to answer questions a, b, c, f and g could be done every quarter while task briefing observations (question d and e) should be done more often such as once a month or once a week. Note that one company assigns review and observation tasks to supervisors or managers who are NOT technically familiar with the Act which provides a potentially more critical perspective.
Example 2
Our second example is an act intended to mitigate an unwanted event; call for additional support for changing roof conditions in an underground mine. The second example is intended to generate thoughts about more complex Acts where knowledge and skill are more critical for success, as well as the application of the Act is much more infrequent, thereby less practiced and possibly less reliant on experience.
Much of the content from the previous example Act is relevant to this second example so only information that varies greatly, based on the rationale in the previous paragraph, is provided below.
What is/are the Objective(s) of the CC?
This Objective of the Act is to have a person who observes a significant negative change in heading ground conditions call for additional support to be installed. Significant negative changes would include the following observable conditions …….
What are the important data types to verify Performance Requirements?
All 5 areas (see previous example for list) are relevant but areas 2, 3 and 5 are likely the most important for verification. The call for additional support for changing roof conditions Act is potentially complex. Training (2) and experience to ensure adequate knowledge and skill are very important to successful application of the Act. Selection of personnel (3) that may be exposed to the ground conditions that initiate the Act is also very important. Area 5 may be important if the site recognises that factors such as, for example, production pressure or limited resources may compromise the Act.
What questions need to be answered to verify the status of the CC?
Recognizing the aforementioned most important areas, the following questions are suggested.
- Have the Acts complex knowledge and skill requirements been defined?
- Are they included in quality training?
- Is the knowledge and skill assessed?
- Do tasks that may require the Act recognise the required knowledge and skill?
- Are personnel selected for the tasks based on their relevant training, experience, knowledge and skill?
- Have the significant erosion factors for the Act been identified?
- Are there initiatives to reduce these factors?
- Are the initiatives in place and effective?
Note the verification emphasis has changed somewhat in example two due, mainly, to the difference in complexity between the example Acts.
Specific CC Act basic algorithm
We can now modify the first illustration in this article to create a specific CC Act basic algorithm that includes the verification data sources and frequency of verification. Note that a similar process of algorithm definition can be done using the CC Object information.
