What causes cancer of the larynx?
SmokingAlcohol consumptionAsbestos can contribute
Slide2What causes cancer of the larynx?
Fibers asbestos particles inhaled and become lodged in the mouth, throat, and lungsWhen lodged in the larynx, they can develop an asbestos tumor – laryngeal cancer
Slide3What are the symptoms?
Chronic hoarseness
Lingering sore throat
Persistent cough
Slide4Medical Issues and Asbestos – Laryngeal Cancer
The IOM committee concluded: Evidence is
sufficient
to infer a causal relationship between asbestos exposure and laryngeal cancer, released June 6, 2006.
Slide5Prognosis of Laryngeal Cancer
Treatable if caught early65% of patients live for at least 5 years55% of patients live more than 10 years
Slide6Other Potential Related Health Concerns
GASTROINTESTINAL CANCER Cancer of the digestive tractAsbestos Corns or Warts
A chronic irritation of the skin by asbestos
fibers. Usually found on the hands.
Slide7Hierarchy of controls
Slide8Warning signs containing specified language in areas that have exposures above the PEL or EL are required.No smoking, eating, or drinking should occur in these areas
Proper PPE must be provided and used to prevent exposure.Hazard communication and demarcation
Slide9Protective Clothing
Coveralls, head coverings, gloves, and foot coverings are required forAny employee exposed above the PELs
Any employee doing work for which a required negative exposure assessment is not produced
Any employee performing Class I work involving removal of > 25 linear or 10 square feet of TSI or surfacing ACM or PACM
A competent person must examine work suits at least once per work shift for rips or tears
Rips/tears must be immediately mended, or the work suit replaced
Slide10Protective Clothing (cont’d
)Contaminated clothing must be transported in labeled, sealed impermeable bags or containers

Slide11Protected?
Slide12Preventative Measures
Follow appropriate work practices and use respiratory protection.
Slide13Asbestos Abatement Requires Use of HEPA-Filtered Respirators
Slide14Preventative Measures
Employers must select, and provide to employees, the appropriate respirators specified in paragraph (d)(3)(i)(A) of 29 CFR 1910.134; however, employers must not select or use filtering facepiece respirators for use against asbestos fibers

Slide18Recognition And Location Of Suspect Asbestos Containing Building Materials
Slide19Site Conditions
Slide20Building Inspections( surveys)
Buildings constructed no later than 1980.
Entire facility.
Must include presence, location, and quantity of suspect ACM.
Buildings with ACM must have trained custodians and/or janitors.
Slide21Duties of Building and Facility OwnersBefore work is begun, identify the presence, location, and quantity of ACM/PACM, including
All TSI and sprayed on/troweled-on surfacing materials in buildings or substrates constructed no later than 1980
All resilient flooring material installed not later than 1980
Notify the following persons of the presence, location, and quantity of ACM/PACM
