Read these news article (from very recently to a couple years ago) about chemical releases and their effects in the recent news.
Pick one of the instances. Find the material safety data sheet (MSDS) for the chemical released. What PPE should be used around these chemicals? What else does the MSDS tell us that is important?
Find another MSDS for a chemical or substance you use regularly. Even something at home (even as simple as hydrogen peroxide). What are some of the precautions you should be taking with it (that you may not be)?

Introduction:
Chemical releases can have significant impacts on both human health and the environment. It is essential for medical college students to understand the potential hazards associated with different chemicals and the appropriate measures to protect themselves and others. In this assignment, we will explore the material safety data sheets (MSDS) for chemicals involved in recent news articles about chemical releases. We will also examine the precautions that should be taken with a commonly used chemical or substance.
Answer 1:
For this assignment, I have chosen the instance of a chlorine leak at an Antioch water park, as reported in the ABC7 News article. The material safety data sheet (MSDS) for chlorine can be found at [insert MSDS link].
According to the MSDS, the personal protective equipment (PPE) that should be used around chlorine includes:
1. Respiratory Protection: A chemical cartridge respirator or a self-contained breathing apparatus (SCBA) should be used in areas where the concentration of chlorine exceeds the permissible exposure limit (PEL). This is because inhaling chlorine gas can cause severe respiratory issues.
2. Eye Protection: Safety goggles or a faceshield must be worn to protect eyes from exposure to chlorine. Exposure to chlorine can lead to irritation, redness, and potentially more serious eye injuries.
3. Protective Clothing: A full-body chemical protective suit or apron made of chemically resistant material should be worn to prevent direct contact of chlorine with the skin. Chlorine can cause skin burns and irritation on contact.
Apart from PPE, the MSDS provides important information about chlorine, such as:
1. Health Hazards: The MSDS states that chlorine is highly irritating to the respiratory system and can cause severe lung damage. It can also irritate the skin and eyes.
2. First Aid Measures: The MSDS provides specific recommendations for first aid in case of exposure or ingestion of chlorine. Immediate medical attention is required, and certain actions like rinsing eyes and skin with water are advised.
3. Safe Handling and Storage: The MSDS outlines proper handling procedures, including measures to avoid the release of chlorine gas, and appropriate storage conditions to minimize risks.
Answer 2:
For this part of the assignment, I have chosen hydrogen peroxide as the commonly used chemical. The MSDS for hydrogen peroxide can be found at [insert MSDS link].
The precautions that should be taken with hydrogen peroxide include:
1. Eye and Skin Protection: Safety goggles and gloves should be worn when handling hydrogen peroxide to avoid contact with eyes and skin. Hydrogen peroxide can cause eye and skin irritation.
2. Ventilation: It is important to ensure proper ventilation in the area where hydrogen peroxide is used or stored. This helps to prevent the buildup of vapors, which can cause respiratory irritation.
3. Compatibility: The MSDS mentions that hydrogen peroxide can react with combustible materials or reducing agents, releasing heat or even causing explosions. It is important to store hydrogen peroxide away from such substances.
4. Storage and Handling: Hydrogen peroxide should be stored in a cool, dry, and well-ventilated area, away from direct sunlight. It should be kept tightly sealed to prevent degradation and potential release of oxygen gas.
By following these precautions, the potential risks associated with hydrogen peroxide can be minimized.
In conclusion, understanding the content of material safety data sheets (MSDS) is crucial for assessing the hazards associated with chemicals and substances. The MSDS provides information on personal protective equipment (PPE) requirements, health hazards, first aid measures, and safe handling and storage recommendations. By being aware of these details, medical college students can effectively protect themselves and others from chemical hazards.
