Download the Document Change Request Form👈

The document change request is part of the document management procedure so that the document can be modified as per the changes and requirements. The document can be of any kind but the change should be made as per the requirements.

The procedure starts with the launch of the request form which helps in identifying the change, the part which should be changed, and if it is feasible for change or not. Through a proper assessment, the change is documented and sent to the endorsement person who reviews it and forwards it to the senior for approval.

Post-approval, the change is documented and the details are logged, while the document revision number, issue date, etc are also changed. It must be remembered, some organizations tend to change the revision number under certain conditions, such as the addition of a new part, major information, etc., while minor change doesn't require a change in the revision number, etc.

Download the Job Safety Analysis - Civil Work👈

Civil work is related to the construction of myriad types of infrastructure for various uses. Civil work consists of the various activities being performed by multiple workers simultaneously at shared premises.

The construction sector is a complex working industry due to the diverse nature of the hazards and the rapidly changing circumstances which often lead to accidents if hazard identification and risk assessment are not performed comprehensively.

The regulations impose the duty on the employer to ensure that work activity-related risks are evaluated and mitigated to make the workplace safe and reasonable for work activities. The risk assessment is done to assess the risk but the Job Safety Analysis plays a vital contributory role in the breakdown of the work activity into small steps and evaluate the risk level so that appropriate controls are adapted for implementation.

Failure Modes and Effects Analysis - A Hazard Identification Technique

Introduction

Failure is a state or condition of the system, process, procedure, or equipment of not meeting the desired target or condition. In other words, it is the termination of the equipment, process, or worker's ability to perform the desired action. Failure Modes and Effects Analysis (F.M.E.A) is a technique used to identify the modes of the failure of the process, or equipment and the critical effects it has on the system so that they can be analyzed.

The technique consists of two different phases which are described as "Failure Mode" which refers to the means or ways in which a product, equipment, or process can fail. "Effects Analysis" is the stage that includes the decomposition of these failures into sub-components and parts for the detailed examination. In summation, Failure Mode and Effects Analysis (F.M.E.A) refers to a step-by-step approach to systematic inspection of components of a system, product, or process, and identifying the critical effects on the end user so that improvements can be suggested by providing proffering cost-effective solutions.

It is also used in incident investigation, and hazard identification as well as during the designing of the equipment so that the equipment that can fail can be identified and suitable action is taken to prevent the mishap. The findings are documented and made available to all of the involved stakeholders. In the continuous process, it is like a living document with credible information about the equipment that can fail at any time and how to control the accident.

What is the Importance of Failure Modes and Effects Analysis technique?

• Presents options for addressing the failure modes and their consequences in advance;
• Comprehensive fault detection mechanism;
• Assists in assessing the performance of the system;
• An effective mechanism for identifying the critical impact on human safety during system failure;
• Provides an opportunity to adapt cost-effective controls against identified failure modes;
• Product and process reliability is enhanced;
• Provides an opportunity to satisfy the customer;

When to Perform Failure Modes and Effects Analysis?

The Failure Modes and Effects Analysis technique is used in various circumstances but generally, it is ideal for use when;

• When a product, process, or equipment is being designed or redesigned;
• When an existing equipment, product, or process is being applied in a different manner;
• When modifying the existing controls and suggesting new plans;
• When a customer is not satisfied as indicated by the feedback;
• When the existing system or product is being analyzed for failure
• Hazard Identification, Incident Investigation;
• On regular intervals throughout the life of the product, process, equipment, etc.;

Types of Failure Modes and Effects Analysis (F.M.E.A)

There are two major types of the FMEA technique;

• Design Failure Modes and Effects Analysis (DFMEA)

• Process Failure Modes and Effects Analysis (PFMEA)

Procedure for Implementing Failure Modes and Effects Analysis (F.M.E.A)

Assemble a cross-functional team involved in the development of the product/ process with diverse knowledge of components, process, operating procedure, customer needs, etc. These functions can include designing, manufacturing, reliability, quality, maintenance, procurement, sales and customer service, etc.

• Product/ Process Description

• Flow Chart Creation

• Function Identification

• Failure Modes

• Consequences Identified

What are effects on the overall system, environment, human safety, behavior, etc are identified? What happens when the system fails? Process engineers should be consulted during this phase to collect comprehensive information.

• The severity of Failure Determination

The severity rating is allocated between 1 to 10 where 1 is insignificant and 10 is catastrophic. This helps in prioritizing the issues and catastrophic one is dealt with on a priority basis.

• Root Cause Identification

The root cause of each failure mode is determined and recorded. It can be either a weakness in the design phase or a shortcoming in an operating procedure. All of the root causes should be recorded and documented.

• Occurrence Likelihood

This includes the likelihood of failure of equipment/process during the lifetime, rated between 1 to 10 where 1 represents highly unlikely and 10 shows the failure will definitely occur.

• Control Measures Determination

The suitable controls should be identified and recorded for implementation to prevent the failure from reaching the user. These controls should prevent the occurrence or reduce the impact severity.

• Determination of Detection Rating

The control implemented should be determined how effective they are in tracing the failure mode or cause of failure before the user is affected. The rating is given between 1 to 10 where 1 shows the control will definitely detect the failure and 10 shows the control will not be able to detect the failure.

• Risk Priority Number (RPN)

Risk Priority Number (RPN) is representative of Severity, Occurrence, and Detection. This helps the process engineer to allocate the number to the failures and put them in an order according to their number so that the most severe can be addressed first.

• Identification of Recommended Actions

This includes the design or process changes to reduce the risk level or likelihood of occurrence.

• Responsibilities and Time Frame

Responsibilities should be allocated and the timeframe given to complete the task. It will provide the opportunity to track the progress of improvement.

• Results Determination

All of the results should be determined post-application of the suggested controls.

• Re-Assessment
