3. Defination of hazard ( ref no. 3) A hazard is any source of potential damage, harm or adverse health effect on something A  is something which could be dangerous to you, your health, or safety, or your plans or reputation. AIR BASED HAZARDS include air pollution also. 3 Air based hazard

9. Preliminary hazard analysis ( pha ) (ref no.2) The preliminary hazard analysis technique is a broad, initial study used in the early stages of system design. It focuses on (1) identifying apparent hazards, (2) assessing the severity of potential accidents that could occur involving the hazards. (3) identifying safeguards for reducing the risks associated with the hazards. This Preliminary Hazard Analysis (PHA) has been prepared to identify, evaluate , and make recommendations for elimination, mitigation, and control of hazards.( ref no.5) 9 Air based hazard

10. THE PHA SHALL CONSIDER ( REF NO.1.) 1 .  Hazardous components . 2.  Safety related interfaces between various system elements, including software . 3.  Environmental constraints including operating environments . 4.  Operating, test, maintenance, built-in-tests, diagnostics, and emergency procedures . 5.  Facilities, support equipment, and training . 6.  Safety related equipment, and possible alternate approaches . 7 .  Malfunctions to the system, subsystems, or software. 10 Air based hazard

11. A TYPICAL PHA TEAM MAY CONSIST OF: (REF NO.1) 1.A team leader ( facilitator) with competence and experience in the method to be used. 2.A secretary who will report the results. 3.Team members (2-6persons) who can provide necessary knowledge and experience on the system being analyzed. 11 Air based hazard

12. PHA prerequisites ( ref no.1) 1 .  Establish the PHA team 2 .  Define and describe the system to be analyzed i.  System boundaries (which parts should be included and which should not). ii .  System description; including layout drawings, process flow diagrams, block diagrams . iii.  Use and storage of energy and hazardous materials in the system. iv .  Operational and environmental conditions to be considered . v.  Systems for detection and control of hazards and hazardous events, emergency systems, and mitigation actions. 3 .  Collect risk information from previous and 12 Air based hazard

13. PHA main steps (ref no.1) 1 .  PHA prerequisites 2 .  Hazard identification 3 .  Consequence and frequency estimation 4 .  Risk ranking and follow-up actions 13 Air based hazard

14. PHA worksheet ( ref no.1) The results of the PHA are usually reported by using a PHA worksheet (or, a computer program). A typical PHA worksheet is shown below. Some analyses may require other columns, but these are the most common. hazard Accidental event(what, where, when) causes Preventive action 14 Air based hazard

15. SEVERITY OF HAZARDS ( REF NO. 1) 1.Critical: failure results in minor injury or death of people. 2.Major: failure results in low level of exposure to personnel. 3. Minor: failure results in minor system damage but does not cause enjury to personnel. 15 Air based hazard
