Hazardous Materials Flashcards
Wastes that are harmful or fatal when ingested or absorbed.
Toxic waste (toxicity)
Acids or bases capable of corroding metal containers
Corrosive waste (corrosivity)
Unstable under normal conditions. They can cause explosions, undergo violent reactions, generate toxic fumes, gases or vapors or explosive mixtures when heated, compressed, or mixed with water.
Reactive Waste (reactivity)
Wastes that can create fires under certain conditions, are spontaneously combustible, or have a flash point of less than 140F(60C)
Ignitable wastes (ignitability)
Example of corrosive waste
Battery acid
Example of reactive waste
Lithium batteries
Explosives
Example of ignitable waste
Waste oils
Used solvents
What part of the school should be tested for radon?
1st floor classroom
Toxic lead exposure levels
Blood: 10µg/dL
Air: 0.15 µg/m3
Water 15 µg/dL/L
EPA’s maximum acceptable level of radon?
4pCi(picocuries)/L
BSL-1 Organisms
Organisms not known to consistently cause disease in humans. (Minimal hazard):
BSL-2 Organisms
Biological agents or toxins associated with causing disease in humans of varying severity. Poses “moderate hazard”. Not known to be transmissible via aerosol.
Hep B
HIV
Measles
Flu A
Dengue
Giardia
Campylobacter
Brucella
Shigella
Yersinia
Bacillus anthracis(if procedures could potentially create aerosols of the toxin, then considered BSL-3)
Clostridium botulinum (if procedures could potentially create aerosols of the toxin, then considered BSL-3)
BSL-3 Organisms
Organisms with a potential for respiratory transmission through aerosols. Can cause serious and potentially lethal infections. (Serious hazards)
Leishmania
Mycobacterium tuberculosis
Mycobacterium
Bacillus anthracis(Anthrax)
Clostridium botulinum
Salmonella typhi
Coxiella burnetti
Rickettsia ricketsii
Yellow fever
BSL-4 Organisms
High transmission via aerosol making it more dangerous for lab workers and the community.
Marburg
Ebola
Lassa fever
Crimean-Congo fever
Small Pox
