Get Help Now!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 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.
QUESTION 3
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 4
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
