  1. انتظار میرود دانشجو در پایان جلسه بتواند: 1- اصول تهویه صنعتی را بیان کند. 2- اهداف تهویه صنعتی را شرح دهد. 3- تفاوت تهویه صنعتی و تهویه مطبوع را بیان کند. 4- نحوه جمع آوری اطلاعات در مورد سرچشمه آلودگی را شرح دهد.

  2. Outline – Controlling Airborne Hazards • Hazard Control Options • Local Exhaust Ventilation Systems (LEVS) • Dilution Ventilation for Contaminant Control

  3. Hazard Control Options • Remember • Identify (Chapters 4 & 5) • Evaluate (Chapters 4 & 5) • Control (This Chapter!) • Engineering Controls • Administrative Controls • Personal Protective Equipment (PPE)

  4. Engineering Controls • Equipment design changes • Automation, enclosures, etc. • Reduce or prevent release of contaminants • Substitution • Use a less hazardous material • Work practice changes • Fundamentals of work methods engineering • Including personal hygiene • Improved housekeeping and maintenance • Constant vigilance!

  5. Administrative Controls • Use only after engineering controls! • Control or limit human access • Worker rotation • This is a great tool, but remember it now exposes even more workers • Worker training

  6. Worker Training • Can be effective if consistent and appropriate • Specialized • Special work practices/procedures • Emergency situations (spills, uncontrolled releases of contaminants, etc.) • Training effect can be noticeable immediately following training, but these results decrease over time without further training (Hawthorne Effect?)

  7. Ventilation shall mean the provision, circulation or exhausting of air into or from an area or space Local exhaust ventilation shall mean the mechanical removal of contaminated air from the point where the contaminant is being generated or liberated.

  8. Dilution ventilation" means inducing and mixing uncontaminated air with contaminated air in such quantities that the resultant mixture in the breathing zone will not exceed the permissible exposure limit (PEL) specified for any contaminant.

  9. "Exhaust ventilation" means the general movement of air out of the area or permit-required confined space by mechanical or natural means.

  10. Tempered make-up air" "means air which has been conditioned by changing its heat content to obtain a specific desired temperature.
