MDE 9 Q11

B) Fire-Fighting Measures

Explanation: The "Fire-Fighting Measures" section of the MSDS provides specific guidance on how to handle fires involving the fuel, including recommended extinguishing methods and safety precautions.

B) Precautions to avoid skin contact and inhalation

Explanation: The Health Hazards Identification section provides information on the precautions necessary to prevent health risks, including avoiding skin contact and inhalation, as well as potential health effects from exposure.

B) Dry chemical powder or carbon dioxide (CO2)

Explanation: Distillate fuel oil fires are typically best controlled using dry chemical powders or CO2 extinguishers. These agents are effective in smothering the fire and cutting off the supply of oxygen, which is crucial for controlling fuel oil fires. Water is not recommended because it can spread the fire.

A) Stability and Reactivity

Explanation: The Stability and Reactivity section addresses potential physical and chemical hazards, including how the substance might react under certain conditions and any stability concerns. This section helps users understand the risks related to the chemical’s reactivity and stability.

C) Wear appropriate protective clothing and breathing apparatus

Explanation: Firefighters should wear appropriate protective clothing and breathing apparatus to protect themselves from heat, smoke, and toxic fumes. This ensures their safety while dealing with hazardous fuel fires.

A) Recommended types of respirators and personal protective equipment

Explanation: The "Fire-Fighting Measures" section provides details on the necessary personal protective equipment, such as respirators and protective suits, to ensure that firefighters can safely work in hazardous conditions.

B) First-Aid Measures

Explanation: The "First-Aid Measures" section of the MSDS provides detailed instructions on how to address various exposure scenarios, including skin contact, inhalation, ingestion, and eye contact. This section is specifically designed to guide users on immediate actions to take to mitigate health effects.

C) Health hazards and safety precautions

Explanation: MSDSs provide detailed information about the health hazards of a substance, including potential effects from exposure and necessary safety precautions. This section helps users understand the risks associated with handling the fuel and how to protect themselves.

A) Spread absorbent materials over the spill and use proper disposal methods

Explanation: For fuel spills, the MSDS recommends using absorbent materials to control and clean up the spill. This helps prevent the spread of the contaminant and reduces the risk of additional fires or environmental damage. Using high-pressure water jets could spread the spill, and ignoring the spill is unsafe.

C) Steps to take for moving the person to fresh air and seeking medical attention

Explanation: If someone inhales vapors from distillate fuel oil, the "First-Aid Measures" section will typically recommend moving the affected person to an area with fresh air and seeking medical attention. This is important to prevent respiratory issues and ensure proper medical evaluation.

C) Health Hazards Identification

Explanation: The Health Hazards Identification section of an MSDS outlines the potential health effects associated with exposure to the chemical, such as symptoms of exposure, chronic health effects, and recommended precautionary measures.

A) Flush eyes with water for at least 15 minutes and seek medical attention

Explanation: The recommended first aid for eye contact with distillate fuel oil is to flush the eyes with water for at least 15 minutes to remove any residue and reduce irritation. Seeking medical attention is crucial to ensure no serious damage occurs.

B) Do not induce vomiting; seek immediate medical attention

Explanation: If someone ingests distillate fuel oil, inducing vomiting is not recommended due to the risk of aspiration and potential further damage. Instead, immediate medical attention is necessary to provide appropriate treatment and prevent complications.

B) Move the person to an area with fresh air and seek medical advice

Explanation: For inhalation exposure, the primary first aid measure is to move the affected person to fresh air to reduce exposure. Seeking medical advice ensures that any potential respiratory effects are properly evaluated and managed.

A) Procedures for dealing with fuel spills and leaks

Explanation: The MSDS includes emergency response procedures for dealing with spills and leaks, which is crucial for minimizing environmental impact and ensuring safety during accidents or emergencies. This section guides users on how to manage and respond to such incidents effectively.
