Unit I Assessment

1. Many countries have now implemented the Globally Harmonized System (GHS), which is formally known as the Globally Harmonized System of Classification and Labelling of Chemical Substances. In the United States, the Occupational Safety and Health Administration (OSHA) modified the HAZCOM standard in 2012 to align with the GHS process requirements, including both safety data sheets (SDSs) and warning signs.

Describe the importance of GHS and why all countries should adopt this system.
What is an SDS, and what is its relationship to GHS? With the exception of the chemical identification section, choose at least two sections of the SDS, and discuss why they are important in the management of hazardous materials and in responding to hazardous material incidents. (You may use your experience at home or in the workplace in your discussion, if applicable.)

Your response must be at least 200 words in length.

2. Your company has been audited by a third-party company to determine if hazardous materials could potentially be discharged outside property boundaries. Of most concern in their findings is the storage of concentrated sulfuric acid located approximately 500 feet uphill of a manmade lake. The acid is currently stored in a flat-top cylindrical tank that has an inside diameter of 4 ft and a height of 6 ft. The tank is sitting on a 12-inch rack within a concrete berm that has inside measurements of 10 ft by 10 ft and 12 inches high. Records indicate the tank has a maximum capacity of 500 gallons. In order to respond to the auditors findings, your tasks are to address the prompts below.

Show the chemical formula of sulfuric acid, and calculate its molecular weight.
Verify if the volume of the tank on record (500 gal) matches the volume that is calculated from the actual dimensions.
Determine if the concrete berm has enough capacity to hold 110% of the actual (calculated) full-tank capacity. Neglect the space occupied by the tank rack within the berm.

Show your complete solution to all parts (a through c), and include your explanation. Your response must be at least 200 words in length.
