Unit I Journal
Instructions
The United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was developed to promote the sound management of chemicals. This is an agreed upon management approach, but regulatory authorities in countries adopting the GHS will implement the system according to their own regulatory processes. After reflecting on the aspects of chemical management that the GHS system covers, describe how you believe the GHS system will affect you or others in your field as your perform your various job functions.
Your journal entry must be at least 200 words. No references or citations are necessary.

Unit III Journal
Instructions
When certain hazardous chemicals are stored or mixed together, violent reactions can occur. Section 7 of the new GHS Safety Data Sheet includes a section describing any chemical incompatibilities. Reflect on the importance of this section and a general understanding of chemical incompatibility in the workplace. What tool do you currently use and intend to use to evaluate chemical reactivity and incompatibility in your workplace?
Your journal entry must be at least 200 words. No references or citations are necessary.
Instructions
For this assignment, you will compose an essay about the concept of chemical incompatibility including practical information involving two common chemical products.
Choose bleach (a base) and another household chemical product that is an acid and review the product labels. You can access product labels and Safety Data Sheet (SDS) information on the Internet.
Record each product’s chemical formulation.
Review Section 7 of the product SDS and summarize that information as it relates to the chemical incompatibility and storage of the bleach and the other product that you chose.
Next, you will use the U.S. EPA Chemical Mixing Compatibility Chart and comment on any chemical incompatibilities associated with the product/chemical(s) that you selected. Include such information as the chemical reactions that could occur if the two products somehow became mixed with one another during an emergency response incident. Also, identify how the chemical properties, uses, and other unique hazards of these two products can affect the tasks and safety of first responders (environmental health and safety/fire service professionals) to an emergency response incident. The chart can be found by clicking here and scrolling down to page 18. There, you will find a description of the chart and the chart itself on pp. 20-21. You are not required to read the rest of the document.
Summarize and compare the usefulness of the SDS information and the compatibility chart. Were the two references in agreement, or did you find that the information was contradictory? Include a discussion on how you intend to use chemical incompatibility information to keep your workplace or home safe.
Your response must be at least one page in length. You are required to cite the SDS and the U.S. EPA Chemical Mixing Compatibility Chart in your response. All other sources used, including the textbook, must be referenced. Paraphrased and/or quoted materials must have accompanying citations in APA format. You must cite at least three sources in your response.

Review Appendix A of OSHA’s Process Safety Management (PSM) Standard 29 CFR 1910.119 and determine if your workplace has any chemicals that exceed the Threshold Quantity (TQ) identified in this table. Reflect on how your workplace uses aspects of the PSM to ensure a safe workplace? Do you think that the measures at your workplace achieve safety or merely keep the facility in compliance?
Your journal entry must be at least 200 words. No references or citations are necessary.
Instructions
OSHA issued the Process Safety Management of Highly Hazardous Chemicals Standard (PSM) (29 CFR 1910.119) which contains requirements for the safe management of chemicals for companies that exceed OSHA's threshold quantities for highly hazardous substances. This standard requires the establishment of a management program that includes conducting process hazard analyses, establishing detailed operating procedures, and includes other important requirements to mitigate the possibility of a serious, chemical related incident occurring at the facility.
For this assignment, suppose you are a safety manager at a chemical manufacturing facility that manufactures concentrated nitric acid. You have heard that employees who load nitric acid into rail tank cars have been checking the pre-inspection checklist from the rail shipping office instead of actually inspecting the vehicles with the checklist in hand as required by the operating procedure. This has not been the first time the shipping crew has been lax about process safety related work rules. Based on this scenario, please compose a research paper which includes the following information:
Identify the chemical properties, uses, and primary hazards associated with common oxidizers including concentrated nitric acid.
Identify important occupational exposure limits (OELs) associated with at least 3 common oxidizers.
Identify PSM requirements that would be useful for preventing or minimizing the consequences of a significant oxidizer related incident.
Using the OSHA Standard and your own experience, justify and validate the importance of the PSM standard to your facility (if it stores and processes highly hazardous materials) or a facility that may impact your community or a near-by community. Examples might include a water treatment facility that utilizes liquefied chlorine gas, a coal fired power plant that utilizes liquefied chlorine gas for water treatment, a food processing plant with a large ammonia refrigeration system, a fertilizer manufacturing or storage facility, a chemical manufacturing facility, etc..
Your research paper must be at least two pages in length. You are required to cite the OSHA Standard 29 CFR 1910.119 in your response as well as at least two other sources, one of which must come from the CSU Online Library. All sources used, including the textbook, must be referenced. Paraphrased and/or quoted materials must have accompanying citations in APA format.

Instructions
Your company has been contracted to assess and cleanup a site that previously had a manufacturing facility for an organochlorine pesticide (i.e., aldrin, chlordane, dieldrin, eldrin, or heptachlor). You are tasked with shipping these wastes off-site to a treatment, storage, disposal facility (TSDF) for disposal.
Review the information found in the 16-point GHS SDS for at least two of the organochlorine pesticides detailed in this question. Describe how you would prepare for transport of these materials and ensure proper shipping documentation based on DOT regulations (hazard class, descriptions, labels, markings, and placards). Describe the importance of having these regulations in place when transporting hazardous materials.
In the event that there is an emergency release of the material while being transported, describe the chemical properties, uses, and ill effects that first responders may encounter upon arrival to the scene.
Summarize the information found in the SDS, and explain how that information prepares EHS and FS professionals to assess and mitigate workplace hazards related to organochlorine pesticides during the assessment and cleanup phases of the project.

Instructions
For this assignment, you are the lead incident commander for a hazardous materials incident similar to those that have been introduced in this course. In this scenario, diisocyanates [toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI)] are being unloaded at the tank farm of HLF Polyurethane Manufacturing. TDI and MDI are used as raw materials in the production of polyurethane.

The incident commander implemented actions required under the approved emergency response plan.
The ERT was not able to immediately isolate the source of the incident.
The fire department arrived on location and assumed the incident command of the event.
Additional Relevant Information:
The facility encompasses an area measuring 2000 feet by 1400 feet.
