Asbestos Awareness Training Miller Pipeline Corporation
Section 1 Introduction
What is asbestos? • Microscopic Spear-Shaped Fibers
What is Asbestos? • Comes from Earth’s surface. • Mined like coal. (Canadian Asbestos Mine)
What is asbestos? • Breaks apart easily. • Extremely light weight. • If one piece was dropped 6’ from the ground in a room with no wind, it would take 8-10 hours for it to hit the floor!!
What is Asbestos? • Has existed for billions of years. • Was used in building products for 80 years.
Why was is it Used? • Great Insulator • Fire Retardant • Chemical Resistant • Very Durable & Strong
Typical materials handled by MPC What is it in? • Over 3,000 materials can contain asbestos: • Insulation • Ceiling Tile • Flooring Tile • Brake Pads • Shingles • Valve Packing • House Siding • Coal Tar Coating
Section 2 Asbestos Hazards
How can it Enter Body? • Inhalation (Breathing) • Ingestion (Swallowing) Can NOT be absorbed through eyes or skin.
Why is it Hazardous? • Fibers get lodged in lungs or stomach. • Body can not break down fibers. • Scar tissue is formed over fibers. • This can lead to serious illness: • Cancer (lung, stomach, colon) ~ 30 Years Later • Mesothelioma ~ 20 Years Later • “Asbestosis” ~ 15 Years Later
Things to Know • Safe level of exposure not currently known. • Smoking + asbestos = 50 x chance of cancer. BOTTOM LINE = Take asbestos exposure seriously, but…
Things to Know • There are two types of asbestos: • Friable: Can become airborne with hand pressure. • Non-Friable: Cannot become airborne unless grinded, sanded or burned. (materials handled by MPC) • Asbestos is only harmful if airborne. • We have ALL been exposed to asbestos: • Apply brakes while driving • Traveling down dusty road • Remodeling or renovating home … do not panic!
Section 3 Required Procedures
General Procedures • Trained Foremen must oversee removal of “Asbestos Containing Materials” (ACM). • Jobsites must be walked before work each day to identify, communicate & eliminate hazards.
General Procedures • Notify MPC & customer safety staffs prior to removing more than 260 linear feet of ACM.
General Procedures • NEVER sand, grind, or burn ACM without approval from MPC & customer safety staff. • When working with ACM: • Do not consume food/drinks or chew gum • Do not chew tobacco or smoke
Task-Specific Procedure Removing Coal Tar Coating
Removing Coal Tar Coating • Carefully expose the pipe to minimize contact or damage. • Inspect the coating to ensure it is not loose & likely to become “friable”.
Removing Coal Tar Coating • Prepare tools & materials. • Put on additional PPE (gloves & glasses).
Removing Coal Tar Coating • Place plastic sheeting under pipe.
Removing Coal Tar Coating • Thoroughly soak coating with “amended water” (i.e. soap water)
And more water! And more water! And more water!
Removing Coal Tar Coating • Score pipe with knife for clean cut ends. • Remove wrap with chipping hammer & putty knife. • Spray coating as needed to keep wet.
Removing Coal Tar Coating • Pick-up and place any loose debris on sheeting. • Spray all materials on sheeting once again. • Tightly roll sheeting inward. • Place sheeting in garbage bag.
Removing Coal Tar Coating • Clean tools with rags & amended water. • Place rags & disposable PPE in garbage bag.
Removing Coal Tar Coating • Seal Garbage Bag • Place Garbage Bag into 6-mil Bag • Spray Inside of 6-mil Bag
Removing Coal Tar Coating • Place Spray Bottle inside 6-mil Bag • Seal 6-mil Bag with Duct Tape
Removing Coal Tar Coating • Place 6-mil Bag inside another 6-mil Bag • Seal that Bag with Duct Tape • Apply Warning Label on Bag or Mark “Danger – Contains Asbestos” if no Label is Available
Removing Coal Tar Coating • Ensure Air-Tight Seal
Removing Coal Tar Coating • Give Bag to Customer for Disposal • If Customer Declines Disposal Responsibility, Contact the MPC Safety Staff • Overnight Storage Must be in Locked Truck
Task-Specific Procedure Drilling Transite Siding
Identifying Transite Siding • Hard Compressed Boards • Nailed in Place Like Roofing Shingles • Very Brittle (Shatter if hit with Hammer) • Bottom Edge Sometimes Wavy • Surface is Often Textured
Drilling Transite Siding • Prepare tools & materials. • Put on additional PPE (gloves & glasses). • Place wet sponge over siding. • Drill through sponge. • Use clean rag & amended water to clean siding and tools. • Place rags & sponge into sealable bag. • Give to customer for disposal.
Section 4 Conclusion
Conclusion • Asbestos is not Hazardous if Necessary Precautions are Taken. • Make Sure to Follow Procedures, Even Though our Exposure is Minimal.
