Scenario 3: Remediation at an *old* refinery

Standardized training for the operation and interpretation of direct-reading meters is severely lacking. While most users are able to calibrate and operate the meter within the range of alarms, readings are often misinterpreted creating a potential Immediately Dangerous to Life or Health (IDLH) situation.
Scenario 3 
It is remediation work at an old refinery. The PID data log shows constant readings at 199 ppm, for the last hour. Your combustible gas meter shows 0% LEL. 

Which direct-reading instrument would you have the workers use in order to have them safely investigate the situation? Electrochemical sensor? Thermal conductivity sensor? NDIR? Colorimetric tubes?
Do your first responders have the knowledge and skills needed to make decisions in situations like this?
Through case studies and real-life scenarios, AIHA’s Train-the-Trainer 4-Gas Monitor/PID Field Use course enables first responders, fire fighters, environmental field technicians and persons doing confined space entries to improve their interpretation of direct-reading instrument output — giving them the knowledge and skills needed to keep you and your coworkers out of harm’s way.
Train-the-Trainer 4-Gas Monitor/PID Field Use is being held on Saturday AND Sunday at the Indiana Convention Center in Indianapolis, Indiana.

Real-Time Detection Systems
Two Day Course
Cost $750.00

This PDC provides the knowledge and helps develop the skills needed to train field persons in the operation of Portable Gas Detection Instrumentation, focusing on delivering training to meet the body of knowledge requirements of the AIHA Registered Operator credential. At the end of this PDC, participants will be prepared to train users of the portable 4-Gas Meter and/or the combo 4-Gas Meter/Photoionization Detector (PID).
By your participation in this PDC, you will have completed the first stage towards becoming authorized trainers for the 4-Gas Detection Registry Preparation course.
Participants must bring 4-Gas or 4-Gas/PID detection equipment.
Upon completion, the participant will be able to:

  • Discuss the difference between calibrating to methane vs. pentane
  • Identify sensor poisons
  • Recognize cross sensitivities to sensors
  • Demonstrate the application of this instrument in measuring toxic contaminants
  • List instrument limitations
  • Cite basic sensor theory and how they work
  • Lead discussions in this area with field personnel
  • Demonstrate proper calibration and use of a variety of portable gas detection equipment
  • Module 1 – Instrument overview
  • Module 2 – Review of basic chemical principles
  • Module 3 – Common terminology
  • Module 4 – Oxygen sensor technology
  • Module 5 – Combustible gas sensors
  • Module 6 – Electrochemical sensors
  • Module 7 – Photoionization detector
  • Module 8 – Calibration of the instrumentation
  • Module 9 – Datalogging
  • Module 10 – Guidelines for selection
Instructors will evaluate participants understanding of the materials presented based on:
  • Post course test
  • Hands-on demonstrations and practicum
  • Practice exercises
  • Workshops
  • Group activities
  • Interactive games

A capillary column gas chromatography method was used for the analysis of sulfur compounds such as hydrogen sulfide, methyl mercaptan, dimethyl sulfide, and dimethyl disulfide in ambient air. The concentration of these sulfur compounds is typically very low (low to sub ppb) in ambient air. Their odor threshold is at the low ppb levels so it is also necessary to make field measurements near odorous sulfur sources such as refineries, pulp and paper mills, etc. because of the hi…

Safety Matters/Teen Workplace Safety Beta Group Task Force

Volunteer opportunity for AIHA members:
I am currently chairing the Safety Matters/Teen Workplace Safety AIHA Beta Group Task Force. We are just getting started and I am  accepting AIHA member volunteers to serve on this task force. Like any task force, this will require a few conference calls and several emails with a specific time limit. Please contact me if you are interested in serving in this capacity.

What is Safety Matters? This general awareness training program developed jointly by the National Institute of Occupational Heath and Safety (NIOSH) and the American Industrial Hygiene Association (AIHA) is designed to teach young workers how to identify workplace hazards and know their rights as workers.

Why is this important? Here are some statistics you may not know:  "Approximately 1.6 million U.S. teens (aged 15–17) work.Every nine minutes, a U.S. teen is injured on the job.On average, each year:59,800 workers under the age of 18 are sent to the ER for job-related injuries37 …
