Overview of Respiratory Protection Training

Overview of Respiratory Protection Training
Tina Perales, Honeywell Safety Products

RESPIRATORY PROTECTION Program United States: OSHA's Standard on Respiratory Protection, §29 CFR 1910.134, requires a Respiratory Protection Program be in place before your workers wear respirators. The program must be site specific, not copied from a "canned" one size fits all template. It must be dynamic, changing as your worksite changes. And it must address all the respiratory hazards that may be encountered at your site.

With more than two decades of experience in industrial safety, Tina Perales has constantly demonstrated that she has her finger on the pulse of the safety industry. Her background includes; extensive industry knowledge, regulatory compliance initiatives, quality assurance, and personnel training. Her knowledge spans head to toe personal protective equipment with a variety of well recognized brand names that include Uvex eye wear, Miller fall protection and North Respiratory products. Her present geographical responsibilities include the greater Los Angeles Metropolitan area, California's Central Valley and California's Central Coast. Her clients range from major corporations such as Boeing to the small and unique businesses with less than 10 employees. Miss Perales is viewed by her peers, senior executive leadership and her current clients as a leader in education regarding safety products. During the last 5 years Tina has successfully trained and certified hundreds of people across multiple industries. She has a people centric approach and has been recognized for her expertise within the safety product industry.



Evaluating Wildfire Smoke and Soot
Michelle Rosales & Larry Wayne,

Forensic Analytical Consulting Services

The presentation will focus on wildfires and their potential smoke impact to neighboring buildings (i.e. residential homes and commercial buildings). The presentation will provide you with background smoke terminology, the chemical make-up of smoke, a step by step smoke impact assessment and the various sampling and laboratory analysis methods available.

Michelle Rosales is an environmental health consultant at Forensic Analytical Consulting Services, in Los Angeles, CA. Ms. Rosales is a Certified Industrial Hygienist (CIH) and has a Master Degree in Public Health majoring in Industrial Hygiene. Ms. Rosales has performed over 500 smoke impact investigations and has provided technical oversight to over 2,000 smoke impact projects.

Larry Wayne is a research microscopist at Forensic Analytical Laboratories in Hayward, CA. Mr. Wayne holds a degree in physics from Michigan Technological University. He subsequently studied microscopy under several widely respected microscopist s, including Walter McCrone and Skip Palenik. He has over 20 years of experience in the field, working on projects as diverse as arson, CD piracy, murder, process control problems, and combustion product characterization, where Mr. Wayne has provided analysis on well over 20,000 samples.

Safety - Personal Protection Equipment - Part 1

Personal protection is a very important part of mold remediation for the workers and the building occupants.

1. Mold Remediation Technicians will use the appropriate containment/enclosures before mold remediation begins. The enclosure will usually be constructed from plastic and tape.

2. Mold Remediation Technicians will suit up in protective clothing, in addition to eye protection and respirators.

3. Mold Remediation Technicians will also establish HEPA filtering and dehumidifying machines.


Mold Removal and Remediation - Part 1

Mold removal, transportation and disposal can be completed:

1.

2.

3.

Negative Air Machine - NAM - Part 1 HEPA Filteration

The pressure of a containment can be kept in a negative pressure environment when the exhaust of the negative air machine is ducted out of the enclosed areas.

In addition to a Negative Pressure Environment, negative air machines maybe allowed to re-circulate the air within the enclosed areas and effectively "scrub" the air (or filter out the small stuff). The picture below illustrates how debris, mold spores, and dust impact the filter of the negative air machine.



HEPA Vacuums and Microbial Wipe Downs - Part 1 Cleaning

The next phase after bulk removal of the contaminated items will be to HEPA vacuum the finer debris from the top of the enclosure to the bottom, paying attention to horizontal surfaces where accumulations of dust and debris may linger.

The beginning of this phase is to remove the majority of the dust and debris from the environment. With HEPA filteration and vacuuming, a microbial wipe down within the enclosure, followed by another HEPA vacuuming is a preferred method used by may mold remediation contractors.

Other procedures such as fogging, either

Final Cleaning - Part 1

Final cleaning of the machines and subsequent removal of the filters can increase the negative air machines ability to filter out particulates and ensure a cleaner environment.

Post Remediation Testing and Verifiaction of Indoor Environment

The final stage to any mold remediation should be to verify the removal of the contaminants, to attain building material moisture and compare indoor to outdoor mold spore concentrations.

The final stage of your mold remediation project may include the use of a 3rd party black mold testing (only) company. Those environments that do not pass first inspections is often 10-25% or more.

Results of the post remediation mold testing will be conveyed to you by the mold inspector or final clearance mold report.
