An In-depth Review of Hood Design and Ventilation

Sponsoring Committee: Engineering Committee

Introductory Course | 1.0 IH CM Point/0.8 CEU/COC Points | Saturday |
8:00 a.m. - 5:00 p.m. | Fee: $305/$385 | Limit: 50

Objectives: Upon completion, the participant will be able to:

• Describe what is important to effective hood design for both capturing and enclosing hoods
• Design hoods that take into account relevant issues in ergonomics, safety, process layout, and work practices
• Describe the effects of cross-drafts and other sources of competing air motions and how to minimize them
• Take pressure and flow measurements much faster than typical practitioners
• Interpret pressure and flow measurements so that they are well worth the time and trouble
• Recognize when assistance from other professionals is required.

Outline:

• Hood Design Recognizing when do you need a ventilation hood
• Choosing between enclosing and capturing hoods
• Designing enclosing hoods and determining their airflow requirements
• Designing capturing hoods and determining their airflow requirements
• Integrating design with ergonomics, materials handling, machine guarding, and common sense
• Effects of competing air movements on hood effectiveness
• Measurement: What to measure, why, and how often
• SP measurements: methods, instruments, and pitfalls
• VP traverses: methods, instruments, and making it much, much faster
• Preparing systems for measurements
• Other good things to measure (e.g., temperature) Tachometers, borescopes, and other useful things
• Blowing smoke without inhaling
• Troubleshooting: making use of measurements without embarrassment or tears

Description: The instructor will describe insights from his practical experience with companies large and small and from his published research. The hood design section is very different from the “Vent Manual” and other courses. The measurement section provides in-depth perspective for the methods described in the latest edition of IVM. If you think you know these topics already, you are in for a surprise. Both topics are discussed in an intensely practical manner. The presentation focuses on designing hoods that are operator, production, and maintenance friendly. The measurement section will demonstrate how Guffey managed to drastically reduce the effort and time required to monitor systems using off-the-shelf equipment with simple, minor modifications. Examples from Dr. Guffey’s consulting and research experience are used liberally.

• Explain the industrial ventilation system parameters and qualitative/quantitative exposure assessments for project commissioning that demonstrate the system performed as designed.

Outline:

• Overview and perspectives
• Review of Industrial Ventilation design principles
• What do I need to know about the process?
• What do I need to know about the operators who run the process?
• Setting an Exposure Control Strategy and success criteria
• Factors that affect Industrial Ventilation system design
  • Inherent risk of materials
  • Contaminant characteristics
  • Degree of integration of ventilation system and process
  • Ventilation impact on product formulation
  • Maintenance strategies
• Commissioning proof of performance and turnover to operations
• Final questions and discussion

Description: In this course, the instructor will describe insights gained from developing industrial ventilation system designs for hundreds of workstations across diverse industries.  Perspectives and rationale provided will help Industrial Hygienists and engineers understand how to establish effective exposure control strategies in a way that makes sense in today’s business environment.  A practical, low tech approach to assessing the process and the people who work around it will be outlined.  Extensive use of photographs will illustrate the various approaches to control contaminants in the workplace.  Practical methods for demonstrating that commissioning requirements have been met will be described.

Industrial Ventilation System Maintenance & Troubleshooting

Intermediate Course | 1.0 IH CM Point/0.8 CEU/COC Points | Sunday |
8:00 a.m. - 5:00 p.m. | Fee: $305/$385 | Limit: 40

Prerequisites: Participant should be familiar with Industrial Ventilation system design concepts, familiarity with the handbook “Industrial Ventilation, A Recommended Practice”, published by ACGIH.
