Question
1
Employees in the paint
department of an automotive parts production facility use styrene to clean
residue off the parts as they come off the paint line. The OSHA PEL for styrene
is 100 ppm as an 8-hour TWA exposure. Personal air samples show that during
peak production times, exposures range from 150 ppm to 200 ppm for an 8-hour
shift. The parts cleaning is performed in a small room with one door.
Using OSHA’s Hierarchy of Controls, write one paragraph for the hazard scenario
above that summarizes your approach to reducing the risks associated with the
hazard. Indicate which type of hazard control you will use, and describe
exactly how it will be used to control the hazard.
Your response must be at least 200 words in length.
Question
2
A press area of a plant
has six 400-ton presses in operation 24 hours a day, 7 days a week. Personal
monitoring using noise dosimeters has shown that 8-hour time-weighted average
(TWA) exposures range from 92.0 dBA to 94.5 dBA.
Using OSHA’s Hierarchy of Controls, write a hazard scenario using the
information above that summarizes your approach to reducing the risks
associated with the hazard. Indicate which type of hazard control you will use,
and describe exactly how it will be used to control the hazard.
Your response must be at least 200 words in length.
Question
3
A plant has an operation
that produces automotive headliners in a press. The process uses a compound
that contains methylene bisphenyl isocyanate (MDI). The compound containing MDI
must be used in the production process to meet the client’s specifications for
the headliner. The OSHA PEL for MDI is 0.02 ppm as a ceiling concentration.
Personal air samples collected for 15 minutes at the time when the press opens
show that short-term exposures range from 0.02 ppm to 0.06 ppm.
Using OSHA’s Hierarchy of Controls, write one paragraph for the hazard scenario
above that summarizes your approach to reducing the risks associated with the
hazard. Indicate which type of hazard control you will use, and describe
exactly how it will be used to control the hazard.
Your response must be at least 200 words in length.
Question
4
A plant that manufactures
automobile chassis includes a production area containing 100 robotic welding
stations. An adjacent area contains 10 welding booths where employees perform
hand welding using MIG welders to rework welds that have been identified as
unacceptable. Personal air sampling shows that personal exposures at 5 of the
welding booths located in the middle of the rework exceed the OSHA PEL for
lead, nickel, and iron oxide fumes. On average, the personal exposures exceed
the applicable OSHA PEL by 2-3 times.
Using OSHA’s Hierarchy of Controls, write one paragraph for the hazard scenario
above that summarizes your approach to reducing the risks associated with the
hazard. Indicate which type of hazard control you will use, and describe
exactly how it will be used to control the hazard.
Your response must be at least 200 words in length.
