HAZWOPER 40 - All Topics Covered (Latest 2024/
2025 Updates STUDY BUNDLE WITH COMPLETE
SOLUTIONS) Questions and Verified Answers|
100% Correct| Grade A
sources of site info - ANSWER- site location map
- site building
- proximity of nearby sensitive human and environmental receptors
- overhead utilities
- entry and access roads
- fire hydrants
- storm drains
- DOT and NIOSH guide books
- property boundary inspection
- interview with site owner
Safety data sheets (SDS) - ANSWERa document that summarizes key information
about a chemical, its composition, which exposures may be dangerous, what to do if
an exposure should occur, and how to clean up spills
oxygen levels - ANSWERatmosphere should be 20% oxygen
- if below 19.5% or above 23%, the air is hazardous
Lower Explosive Limit (LEL) - ANSWERIs the minimum concentration of vapor to air
below which a flame will not propagate in the presence of an ignition source. Also
known as "too lean to burn."
- should be 10%, above this is hazardous
Photoionization Detector (PID) - ANSWERGas detector that measures volatile
compounds in concentrations of parts per million and parts per billion using
ultraviolet light
Flame Ionization Detector (FID) - ANSWERTOV detector; analyte molecules eluting
from the column are burned in a flame and produce electrons. This electric current is
amplified and measured
emergency response - ANSWERresponse from outside the area of the release by
other designated responders where the release results or likely results in an
uncontrolled release of hazardous substances
Hazmat team - ANSWERtypically employees designated by their employer who are
expected to perform work to handle and control leaks or spills of hazardous
substances
, OSHA clean up definition - ANSWERhazardous substances are removed, contained,
incinerated, neutralized, stabilized, cleared-up etc with the ultimate goal of making
the site safer for people or the environment
indicators of hazardous conditions - ANSWER- explosions
- moaning
- electrical sparking
- bulging drums etc.
- subtle indicators: noise, temp extremes, biological, etc.
solid waste dumps - ANSWERfarm dumps are the most common, can be an invitation
to others to dispose of unknown wastes such as:
- PCB, asbestos, pesticide containers etc.
Conceptual Site Model (CSM) - ANSWERGenerally includes a written and graphical
depiction of hazardous threats and how people come into contact with the threats.
- representation of the conditions and processes involved in the transport and
impacts of contaminants
- prepared with the HASP
class 1 hazard - ANSWERexplosives
class 2 hazard - ANSWERgases
class 3 hazard - ANSWERflammable and combustible liquids
class 4 hazard - ANSWERFlammable solids
class 5 hazard - ANSWEROxidizers and Organic Peroxides
class 6 hazard - ANSWERpoisons
class 7 hazard - ANSWERradioactive
class 8 hazard - ANSWERCorrosives
class 9 hazard - ANSWERmiscellaneous
right to know law - ANSWERhazard communication standard that allows each
employee to know of potential exposure problems
- includes hazardous chemical lists
- container labeling
- SDS
- employee training
UN ID Numbers - ANSWERfour-digit numbers that identify hazardous substances and
products of commercial importance.
