Behavior And Safety

  1. 1. PTAS METHOD Foundations Human Behavior and Safety The name PTAS mean: Psychological Techniques Applied to Safety It is a translation from spanish name: “ Tecnicas Psicológicas aplicadas a la Seguridad ” Method developed by L. Lopez-Mena, since 1982.
  2. 2. Ordinary people says about people’s Behavior. They are drinkers They are lazy They are fool (others prejudices) These expressions are only tags, without scientific value. Not valid People´s behavior is a function of its consequences. In every part of the world, people’s behavior on the job, is a function of management system. Our duty as managers is to know how people’s behavior appear, develops and changes, to manage it with scientific knowledge. Psychology is the science of behavior. Scientific research says:
  3. 3. Attitudes are inside a person’s head -therefore they are not observable or measurable, Attitudes can be changed by changing behaviors. However, NO
  4. 4. Behavior: Any directly measurable thing that a person does, including speaking, acting, thinking, and performing physical functions. Behavior can be observable or not. In PTAS Method we work with observable behavior . Behavior definition: ( observable) (internal)
  5. 5. Behavior and Safety. (From scientific point of view) <ul><li>Our attention is directed to observable safe/unsafety behavior </li></ul><ul><li>The behavior is: </li></ul><ul><li>a) Natural phenomena, </li></ul><ul><li>b) Frecuently happen </li></ul><ul><li>c) In relation with methodically and predictable way, </li></ul><ul><li>d) with enviromental events. </li></ul>
  6. 6. <ul><li>An useful tool for collecting data on safe or unsafe behavior </li></ul><ul><li>A scientific way to understand why people behave the way they do, when it comes to safety </li></ul><ul><li>Conceptually easy to understand, but often hard to implement and sustain without Production Manager’s support. </li></ul>Psychology applied Safety: What is it?
  7. 7. <ul><li>Only about observation and feedback </li></ul><ul><li>Concerned only about the behaviors of line employees </li></ul><ul><li>A substitution for traditional risk management techniques </li></ul><ul><li>About cheating & manipulating people & aversive control </li></ul><ul><li>A process that does not need Manager support and involvement. </li></ul>Psychology applied Safety: What It is Not!
  8. 8. Work’s accidents Causes Human Behavior Technical Factors Inheritance En vironment (learning) Study and manage human learning process PTAS Method The causes of work’s accidents
  9. 9. Evaluation of Safety Interventions. (National Safety Council, 1999 ) <ul><li>Strategies Accident’s Reduction in Safety in % </li></ul><ul><li>Behavioral 59.6% </li></ul><ul><li>Ergonomics 51.6% </li></ul><ul><li>Engineering 29.0% </li></ul><ul><li>Problem solution 20.0% </li></ul><ul><li>Governement actions 18.3% </li></ul><ul><li>Management audit 17.0% </li></ul><ul><li>Stress Management 15.0% </li></ul><ul><li>Pictures Campaining 14.0% </li></ul><ul><li>Personnel Selection 3.7% </li></ul><ul><li> </li></ul> % = different numbers of studies
  10. 10. Behavior is explained by human learning process. <ul><li>To know more about human behavior, psychologist made a experimental studies on human learning process , because almost all our behavior is learned behavior. </li></ul><ul><li>The knowledge on learning process, </li></ul><ul><li>is based on scientific research, from the end of XIX century. </li></ul>
  11. 11. Description of PTAS Method The name PTAS mean: Psychological Techniques Applied to Safety It is a translation from spanish name: “ Tecnicas Psicologicas aplicadas a la Seguridad ” developed by L. Lopez-Mena, since 1982.
  12. 12. Objectives, a) Improve and increase the safe behavior of workers through managing human learning process. b) Identify and evaluate behaviors and psychosocial conditions, of the enterprise. c) To use behavioral technology to obtain changes in safety. PTAS METHOD
  13. 13. P T A S METHOD S TE PS This method has five steps : 1. Identify critical behaviors in safety. 2. Measure and register these critical behaviors. 3. Functional analysis of behavior. 4 . Intervention. 5. Assessment and continue (follow on). 200 195 190 185 180 175 170 165 160 155 150 Millions of Dollars 1992 1991 1990 Production Costs Unit Price Profits
  14. 14. <ul><li>A Behavioral Safety process (PTAS Method) is proven to improve safe practices through a positive, employee driven, and continuously improving process. (CIS). </li></ul><ul><li>A behavioral process also allows companies to harness the power of company and individual values for safety. </li></ul><ul><li>This creates a culture where managers and employees work safely for the right reasons rather than one where people simply follow procedures to avoid punishment. (see safety culture) </li></ul>BEHAVIORAL SAFETY PROCESS
  15. 15. P. T.A .S. Method, Case Studies and RESULTS
  16. 16. Safety behavior level before PTAS Intervention Case 1. In Spain.
  17. 17. EXAMPLE PTAS RESULTS IN IMPROVED Safety Behaviors . Decreased microorganism pathogens in meals Case 2. (In Chile) Intervention Baseline of targets behaviors Follow up (3 months later)

(July – October 2006 Observations) </li></ul></ul>EXAMPLE !! Original data obtained with PTAS Method in Wolverhampton Plant (2006) In England
  19. 19. SUMMARY QUALITATIVE EVALUATION PTAS METHOD <ul><li>Good reception by observed by floor associates. </li></ul><ul><li>They appreciate the positive action to change unsafe behavior. </li></ul><ul><li>Decline criticism and complaint. </li></ul><ul><li>Increased teamwork to solving safety problems. </li></ul><ul><li>Changing safety culture on the job. </li></ul><ul><li>Improve communication among workers and managers . </li></ul>
