1. The two important allotropes of phosphorus are white phosphorus and red phosphorus. Compare their production methods and their potentially dangerous properties. Describe the proper placarding on their transport vehicles, and discuss response actions in the event of an accidental release during their transport.
Your response must be at least 200 words in length.
2.You are the manager of the health, safety, and environmental (HSE) department in your company, and one of your tasks is to give training to new or transfer employees to your department. A topic that is being covered in training is the use of the Emergency Response Guidebook (ERG) (hard copy or mobile app version). The incident that you gave the class to evaluate their understanding of how to use the ERG involves a spill of 55 gallons of material in a dry ditch along a dirt road at 5 am. The material has an identification number of 1828. The employees in the class are to address the following prompts based on information from the ERG.
List the specific name of the material and the guide number to be used.
Select the appropriate initial isolation and protective action distances.
Identify potential interactions of the material with water and metals.
Summarize potential health hazards and precautionary measures for the first responders to this incident.
Your response must be at least 200 words in length.

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.
