Lead & Asbestos Hazards

Transcription

1 Lead & Asbestos Hazards Awareness & Health Effects Presented By: Jamie Papian Licensed Lead & Asbestos Inspector Licensed Lead & Asbestos Abatement Supervisor Licensed Asbestos Management Planner HUD Housing Quality Standards Inspector State of Iowa, Illinois and Missouri Certified Training Provider Lead Is A Poison. Has no biological value Affects virtually every system in the body At blood lead levels as low as 5 micrograms per deciliter (µg/dl), children's intelligence, hearing, and growth are affected. (HOW MUCH is that?)

2 What Is Lead Based Paint? Paint or other surface coating that contains lead at or above established limits Federal and State of Iowa standard is greater than 1.0 mg/cm 2 or greater than 0.5% by weight Deteriorated lead-based paint is the primary source of lead poisoning and lead-contaminated dust Where Is Lead Based Paint Found? Interior and exterior building components Commercial and industrial structures Housing built before 1978 Lead can also be found in primers, stains, varnishes, and shellacs

3 Who Can Be Affected From Exposure To Lead? Children Women of child bearing age Adults working in construction; demolition, remodeling, re-painting, restoration Families of lead-exposed workers Pets Exposure comes from inhaling, ingesting and in vitro Sources of Lead Exposure Chewable surfaces, Impact Surfaces, Friction Surfaces Deteriorated interior or exterior paint Contaminated household dust Contaminated bare soil Lead can also be found in: Toys, Jewelry, Make Up Candy Wrappers from outside the U.S. Pottery, Ceramics

4 Health Effects Of Exposure To Lead Based Paint: Children Common symptoms of childhood lead exposure: Fatigue, Stomachache, Constipation Irritability, Headaches, Vomiting Poor appetite Anemia Behavior and leaning problems / Attention Deficit Damage to brain, nervous system and kidneys Slowed growth Hearing problems Health Effects Of Exposure To Lead Based Paint: Adults Common symptoms of adulthood lead exposure: Numbness in hands and feet Muscle and joint pain Wrist drop Weakness in arms and legs Loss of sex drive Kidney problems High blood pressure

5 How Is Lead Poisoning Diagnosed? MOST lead-poisoned children and adults do not have obvious symptoms A blood test is the only way to know if a person s blood lead level is elevated Blood testing for lead is required before a child can enter kindergarten How Do We Stay Safe? Proper Training Protective Clothing and Equipment Good Hygiene Safe work practices: Occupant / Worker Protection Worksite Preparation and Containment Prohibited Methods Worksite Cleanup

6 Lead Based Paint Regulations EPA HUD OSHA State of Iowa What Is Required For Compliance? Training & Licensing Residential properties and child occupied facilities built before 1978 Lead Safe Renovator certification Lead Abatement certification may apply Commercial properties Lead Abatement or Lead Renovator Certification may apply Air Sampling may apply Lead Inspection may be required Lead Clearance testing may apply

7 Asbestos What Is Asbestos? Asbestos is a mineral; mined from the ground in much the same way as iron, lead and copper. Asbestos is classified as either Friable of Non-Friable. Asbestos Excellent fire, heat and sound insulator Does not conduct electricity Generally impervious to chemical attacks Very strong. Pound for pound, asbestos is stronger than steel.

8 Friable vs Non-Friable Friable ACM is any material that contains more than one percent asbestos by weight or area, depending on whether it is a bulk or sheet material and can be crumbled, pulverized, or reduced to powder by the pressure of an ordinary human hand. Non-friable ACM is any material that contains more than one percent asbestos, but cannot be pulverized under hand pressure. Six Types of Asbestos Asbestos is composed of six different types of natural minerals: Chrysotile Most Amosite Common Crocidolite Types Tremolite Actinolite Anthophyllite

9 Vermiculite Vermiculite is mineral composed of shiny flakes, resembling mica. When heated to a high temperature, flakes of vermiculite expand as much as 8-30 times their original size. The expanded vermiculite is a light-weight, fire-resistant, and odorless material and has been used in numerous products, including insulation for attics and walls. Sizes of vermiculite products range from very fine particles to large (coarse) pieces nearly an inch long. Always Assume Vermiculite Contains Asbestos Leave vermiculite insulation undisturbed in attics and in walls. Do not attempt to remove the insulation yourself. Hire a licensed asbestos contractor to remove or encapsulate the insulation.

10 Where Is Asbestos Found? Sprayed on steel beams, columns and decking Siding and roofing shingles Added to asphalt, vinyl and other materials to make exterior siding, roofing felts, floor tiles, joint compounds and adhesives Spray applied, trowel applied or factory installed on or within equipment Troweled or sprayed on ceilings and walls, and used as a decorative product (popcorn ceilings) Where Is Asbestos Found? During renovations and repairs, ACM is commonly found in: Spray textures (Popcorn Ceilings) Floor tiles Duct work tape Insulation/Vermiculite

11 Who Can Be Affected From Exposure To Asbestos? Anyone without proper protection in an area where asbestos is in the air. Even a family member can be affected indirectly by secondhand exposure from an asbestos worker s soiled work clothes. There is no health risk if the asbestos is bonded into intact finished products, such as walls and tiles. As long as the material is not damaged or disturbed (for example, by drilling or remodeling), the fibers are not released into the air air. When Is Asbestos Dangerous? Asbestos is dangerous when you breathe it. Instead of breaking up into dust particles, asbestos divides into millions of tiny fibers. Fibers are microscopically thin, so small they can remain airborne for days after they were initially disturbed. (HOW SMALL ARE WE TALKING ABOUT?)

12 How Small Is A Fiber of Asbestos? The finest fibers are found in chrysotile, the most common type of asbestos. Because of the fine structure of the asbestos, approximately 850,000 to 1,400,000 fibers are found in a linear inch of chrysotile; however, only 630 human hairs can packed into a linear inch. Health Effects of Exposure To Asbestos Three major lung conditions traced directly to asbestos exposure: Lung Cancer Mesothelioma Asbestosis A cigarette smoker that also works with asbestos is 50x more likely to get lung cancer.

13 Safety First Never sand or dry buff asbestos containing floor tiles. Broken and fallen ceiling tiles should be left in place, undisturbed, until identified. Broken and damaged asbestos floor tiles must be removed by licensed asbestos abatement workers. Asbestos Regulations State and Federal asbestos laws have been set into place for handling such issues as: buildings that still contain asbestos, employees who still work around asbestos, building managers and owners of buildings that contain asbestos, cleanup sites, restricting mining of asbestos, and more.

14 What Is Required For Compliance? Training & Licensing Abatement, Supervisor & Worker Inspection Management Planning Project Design Operations & Maintenance Hazard Awareness Each training discipline has its own set of requirements addressing compliance issues such as respirators, medical surveillance, sampling, waste removal, etc. Q&A Air Sampling/Monitoring site, employees Respirator Regulations when it s recommended, but not required, or when the employee chooses to wear one
