1. The Global Harmonization System of Classification and Labeling of Chemical Substances (GHS) has been adopted by the Occupational Safety and Health Administration (OSHA) and the Department of Transportation (DOT).
a. What is the GHS?
b. Why was the GHS developed?
c. Describe the GHS classification system?
d. What is the format for the GHS Safety Data Sheet (SDS)?
e. In your opinion, what are the benefits and drawbacks of this system?
Your response must be at least 75 words in length.
2. A recent industrial facility released lead into the surrounding soil. Soil sampling results indicated the area impacted with lead above action levels is 30 feet by 55 feet. The depth of the lead contamination plume is three feet below ground surface. The land owner wanted to clean this site for future development. Using your textbook, answer the questions below to help you prepare a cost estimate for this portion of the project. Your solutions and any assumptions to justify your estimate must be shown.
a. What is the chemical symbol of lead, and what group/family does it belong to?
b. Solve for the minimum volume of soil that will be excavated in cubic yards?
c. If each dump truck can transport 18 cubic yards, determine how many dump trucks loads will be transported? For calculation purposes, add a 15% “fluff factor” (add to the volume that will be transported).
d. If the bulk density of soil is 1350 kg/m3 (84.3 lb/ft3), solve for the weight of the soil that will be transported to a disposal site in kilograms.
Your total response to parts a-d must be at least 75 words in length.
3. 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 you perform your various job functions. Your journal entry must be at least 200 words. No references or citations are necessary.
