OSHA Act of 1970 – SEC. 5. Duties (a) Each employer -(1) shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees; (2) shall comply with occupational safety and health standards promulgated under this Act. (b) Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct.

Some Things to Remember 90% of events are caused by something OTHER THAN JUST the individual 95% of people respond very similarly to the same stimuli People do what they do at the time that they do it for reasons that make sense to them at the time Human Performance is NOT Common Sense Copyright 2010, Fisher IT, Inc.
Definitions • Error: An action or inaction that unintentionally: • Results in an undesirable or unwanted condition OR • Leads a task or system outside of limits OR • Deviates from a set of rules • Event (or incident): The undesirable result of an error, a set of errors or a set of conditions • Deviation: Not strictly complying with a rule, standard or expectation • Violation: Intentionally not complying with a rule, standard or expectation • Active Error: An action or inaction that results in immediate consequence • Latent Error: An action or inaction that results in consequences that are delayed or create latent conditions • Error Traps - An unfavorable condition that increases the probability for error during a specific action • Error-Likely Situation - A work situation in which there is a greater opportunity for error when performing a specific action or task due to error precursors. • Organizational weakness – weaknesses in the processes or values that allow the existence of an error trap or WITH model characteristic to progress to an event Copyright, Fisher IT, Inc.

Top 5 Procedure Traps to Watch For • Field Decisions • Difficulty • Vagueness and Misleading Information • Multiple Actions • Conflicting Information, Actions & Formats
Trap 1 - Field Decisions The procedure user must make a decision with little or no guidance for making that decision. For example if the user has to: – Decide what to do out of multiple options without guidance – Determine if certain conditions exist – Determine if certain sections of procedure applicable – Determine if the task is completed – Determine if certain requirements are met Decisions made in error prone situations have a field error rate 11 times higher than that of a well written step!
Field Decisions (cont. ) Conditions affecting the quality of Field Decisions are: – The number of aspects to be considered – Existence of a decision aid – Readiness of the information – Decision maker’s experience and personality
Trap 2 - Difficulty Mental Difficulty • Told once (in training, memo, OJT, etc. ) and now the individual must remember to use it and how to use it • Told earlier (in precautions, limitations, procedure step) and now the individual has to figure out when to apply it Physical Difficulty • • • Difficult tasks Unnecessary or unreasonable tasks Easy to shortcut Contact with other organization Has to stop and do something else
Trap 3 – Multiple Actions (& embedded actions) • 3 or more actions in the same step • Actions in a NOTE, CAUTION or WARNING (real or embedded) • Actions in Precautions, Limitations, and Prerequisites
Trap 4 – Vague Terms and Misleading Information Vague Terms • Abstract verbs like: Impact, Affect, Analyze, Determine, Review, Check, Ensure, Verify • Abstract adjectives like: Slow, Fast, Sufficient, Normal, All, Periodically, Routinely • Abstract phrases like: When Directed, As Soon As Management …. , May be, Should
Misleading Information • Misleading information is incorrect, but it’s not easy to detect and avoid the error traps it creates and may involve: – Missing critical steps to carry out a task – Missing critical data – Missing critical references – Missing critical scopes • The most effective ways of discovery of misleading information are walk-through and full scope verification
Trap 5 – Conflicting Instructions Actions that are required by procedural steps but are contrary to the normal actions expected by the workers or formats that are “different” to the user: – Inconsistent actions – Inconsistent words – Inconsistent expressions – Inconsistent format Note: Use of double-negative statements in procedure steps increases the error rate of the step by 280%
IF we teach writers how not to put the traps in AND we teach users how to deal with them before they drive an error Copyright, Fisher IT, Inc.

WITH Model Work Environment General influences on task performance related to workplace, organizational and cultural conditions Task Demands Specific mental, physical or team requirements of a task Individual Capabilities Unique mental, physical and emotional capabilities of an individual related to a specific task Human Nature Generic characteristics of human beings that makes us more vulnerable to errors under certain conditions Copyright 2010, Fisher IT, Inc.
Conclusions • The fit, form and content of instructions has a marked impact on fatality prevention • We have to take the WITH model into account when writing instructions and briefing tasks • Deviation probability can be predicted and avoided if we understand it • We can build quality into the processes by: – Not putting the traps in and / or – Teaching people how to identify and deal with them Copyright, Fisher IT, Inc.
