Stack Sampling Training

LEHDER has a considerable history of sharing our technical expertise. We have provided teaching services at Ontario post-secondary institutions since 1990 and have expanded our efforts internationally through training programs with foreign professionals.

Local Training Efforts

Since 1990 LEHDER has been providing teaching services to Fanshawe College, located in London, Ontario. This effort involves the teaching of both the theory and laboratory sections described in the credit course ENVR-5006 which is part of Fanshawe's 3-year Environmental Technologist program.

LEHDER has also conducted stack sampling training programs at Lambton College located in Sarnia, Ontario at the request of the Centre for Applied Process Technology (CAPT).

International Training Efforts

In 2004 LEHDER conducted an extensive stack sampling training program for a group of six environmental professionals from India. The program involved providing "hands-on" training in stack sampling at a chemical industrial site in the Sarnia area.

Terra International offered its site in Courtright, Ontario for the training program which occurred in June 2004. The training involved instruction in reference methods for the determination of particulate concentrations and mass rates from process exhaust stacks. Mr. Michael Denomme, Principal of LEHDER said "LEHDER has conducted several similar training programs in the past for local colleges and industry; however, this was our first experience in the international forum. It was truly a rewarding experience for all involved. We are very thankful to the Terra plant for allowing us to provide the training at their facility; it was an ideal location and well organized by Terra personnel".

During each portion of the training program LEHDER was committed to providing a safe, effective and highly educational training experience. To achieve this, each trainee was required to complete all necessary safety training and/or certification prior to participation in any field work. This included a one hour basic training course at the Sarnia Lambton Industrial Educational Co-operative for which proof of WHMIS training is a prerequisite. Mr. Denomme said "throughout the field training program we emphasized that safety can only be the highest priority. This includes the proper use of personal protective equipment (PPE) and the ability to identify potential risks associated with each task prior to carrying out the job. Based on our training, we believe that they will return to India with a new appreciation and awareness for working safe."

In addition, the Indian professionals were very impressed and interested in the role played by the Sarnia Lambton Environmental Association (SLEA). Mr. Scott Munro, General Manager of SLEA in 2004, made a presentation to the visitors during their stay and made arrangements for visits to the SLEA water monitoring and mobile air monitoring stations.

The field training conducted in the Sarnia area involved a team of at least three skilled and qualified LEHDER Environmental Specialists. Of the three, one was stationed on the stack platform (assembly and operation of sample box), one was at ground level (control unit operator), and one was located in the LEHDER recovery trailer. Each of the six trainees were stationed with a LEHDER trainer at each of the three sites. Following each test run, the trainees were rotated to a different duty for subsequent test runs, this ensured that each trainee was given the opportunity to become familiar with all aspects of the field work.

Training Program Outline

An outline of the aspects involved in this phase of the training program is located below:

Initial training on-site at the LEHDER office:

  • Program agenda review
  • Review of unit standards and conversion
  • Review field calculations
  • Training on operation of field equipment and techniques
  • Calibration of DGM, nozzles and thermocouples
  • Training on sample recovery techniques, data sheets etc.
  • Pack equipment for field mobilization using checklists

Field training agenda for the plant site:

  • Travel to site
  • Site specific safety orientation
  • Set up equipment on two granulator stacks (3 students per stack)
  • Review process to be tested
  • Conduct preliminary measurements of sources as per the Code
  • Prepare Method 5 sampling trains for testing both stacks
  • Conduct (3) Method 5 particulate test runs on both stacks simultaneously and recover samples (with maximum assistance from LEHDER)
  • Remove equipment from site and return to LEHDER office

Conclusion of training program at LEHDER office:

  • Review of sampling program
  • Data reduction of stack sampling data to determine concentrations and mass rates
  • Wrap up

Although only in Sarnia-Lambton for one week, the Indian visitors were impressed with the warm hospitality and the clean environment and expressed a strong desire to return to the area in the future.

The follow-up phase of the training program was conducted in March 2005 at the Central Pollution Control Board offices in Delhi, India. This involved a review of the training that was provided at LEHDER in June 2004 and an assessment of the sampling equipment and procedures used during a stack sampling experiment at a local coal fired power plant in Delhi.
