Assignment Details:
Review the anticipated worker activities during normal operations.
Review the exposure controls (Hint: Section 8) listed in the SDS document(s) for your selected hazardous substance.
Prepare for exposure assessment activities by explaining the most important hazards and risk factors related to your selected hazardous substance. Update and consolidate this information from previous assignments to provide a high-level overview to the management team.
Identify available occupational and environmental exposure limits for your selected hazardous substance.
Select which exposure limit(s) you would recommend for normal operations and in the event of a spill or release of the selected hazardous substance.
Write a memo to the management team explaining the anticipated worker activities, most important hazards and risk factors, available exposure limits, and your recommendation of selected exposure limits during normal operations and in the event of a spill or release of the selected hazardous substance.
Throughout this course and program, your work will be assessed for assignment-specific items and four general criteria:
Context and purpose: The Unit 7 Assignment is intended to be written as a technical memorandum.
Sources and evidence: Any sources you use should be documented in APA format. In-text citations and a reference list are required.
Writing style: Your report should be written in your own words, with no grammar or spelling errors.
Format and layout: Submit your assignment in one compiled document (.docx or .pdf). As this is a technical memo, the formal APA paper format is not required.
Review the detailed grading rubric for this assignment before beginning to work on it.
