SAFETY STANDARD
This information is a part of a comprehensive reference tool that will help human factors professionals and organizations to efficiently carry out human factors policy. Here we have 11 Safety related Principles to be considered in Human Factors.
These are applied while developing new procedures, instructions, machinery equipment and tools.
Safety Standard 1 – Incorporate safety factors
System and equipment design shall incorporate applicable system and personal safety factors that affect human performance including those that minimize human error in the operation and maintenance of the system under normal, degraded, and emergency or non-routine conditions.
Safety Standard 2 – Provide a fail-safe design
A fail-safe design shall be provided for systems in which failure could cause catastrophic damage, injury to personnel, or inadvertent operation of equipment.
Safety Standard 3 – Make systems error-resistant
Users shall be protected from making errors to the maximum possible extent.
To make a system error-resistant is to make it difficult for a user to make an error. Simplicity in design and the provision of clear information are tools to improve error resistance. Electronic checklists also have the potential to improve error resistance by providing reminders of items that need to be completed.
Safety Standard 4 – Make systems error-tolerant
Systems should be tolerant of human errors. To make a system error-tolerant is to mitigate the effects of human errors that are committed. Error tolerance can be improved by adding monitoring capabilities.
Safety Standard 5 – Warn of potentially unsafe actions
Systems and equipment should warn users before they initiate a task that may result in potentially serious consequences.
Safety Standard 6 – Identify safe and unsafe states and actions
Systems and equipment shall clearly identify safe and unsafe operating states and actions.
Safety Standard 7 – Provide emergency procedures for critical systems
For critical software, systems, or equipment, there shall be a clear, step-by-step description of procedures to be conducted in the event of failure.
Standard 8 – Provide redundancy
There shall be redundant means to access systems and equipment that provide a critical function.
Standard 9 – Design systems to be modular
Systems and equipment should be modular in design. To be modular means to be designed with standardized or uniform components. The advantage of a modular design is that if one component fails, it is easier to replace.
Standard 10 – Prevent damage through design.
Design, location, procedural guidance, and suitable warning labels shall be provided to prevent damage to equipment or personnel while it is being handled, installed, operated, or maintained.
Standard 11 – Prevent misalignment and improper mounting.
Equipment shall include physical features that prevent improper mounting or alignment, or at minimum have labels or codes to identify proper mounting and alignment.
