OSHA Hazard Communication Standard Questions

The statement is true because container labels and Material Safety Data Sheets (MSDS) provide important information about hazardous materials. Container labels typically include symbols, warnings, and instructions for safe handling and storage. MSDS provide detailed information about the properties, hazards, and precautions related to the material, including emergency procedures and first aid measures. Both sources are essential for workers to understand the potential risks associated with the hazardous materials they work with and to take appropriate safety measures.

The statement "Only very hazardous materials must be labeled" is false. In reality, all hazardous materials must be labeled to ensure proper handling, storage, and transportation. Labeling helps to inform and alert individuals about the potential dangers associated with the materials, enabling them to take necessary precautions and prevent accidents or injuries.

The label does not contain all of the required information for a commercial label. It provides information about the flammability of the product, warns against internal use, and gives instructions in case of accidental ingestion. However, it is missing other important information such as the name and address of the manufacturer or distributor, the net quantity of the product, and any necessary hazard warnings or precautionary measures.

Hazard classes on labels are represented by colors. This is because color coding helps to quickly and easily identify the type and level of hazard associated with a particular substance or material. Different colors are used to indicate different types of hazards, such as red for flammable materials, yellow for oxidizers, and blue for health hazards. This color-coded system helps to ensure the safety of individuals handling or working around hazardous materials by providing clear visual cues about the potential risks involved.

The given statement is false. In a rating scale, the higher the number, the more dangerous the substance. This is because rating scales typically assign higher numbers to indicate greater severity or risk. Therefore, a higher number on a rating scale would indicate a substance that is more dangerous, not less dangerous.

MSDSs, or Material Safety Data Sheets, provide important information about hazardous substances. They include emergency first aid procedures, which are crucial in case of accidents or exposure to these substances. They also provide information about carcinogenic factors, alerting users to potential cancer-causing agents. Additionally, MSDSs include contact information for further assistance or clarification. Therefore, the correct answer is "All of the above," as all of these pieces of information are included in MSDSs.

Material Safety Data Sheets (MSDS) are required by law to be available for all hazardous materials present in a work area. These sheets provide important information about the hazards of the materials, proper handling procedures, and emergency response measures. It is crucial for workers to have access to MSDS to ensure their safety and to be aware of the potential risks associated with the materials they are working with. Therefore, the statement that MSDS are not available for all hazardous materials in the work area is false.

An MSDS (Material Safety Data Sheet) provides detailed information about hazardous materials, including their composition, physical and chemical properties, potential hazards, handling and storage instructions, and emergency response procedures. While product labels provide basic information about hazardous materials, an MSDS is necessary when additional information is needed. It helps users understand the potential risks associated with a substance and take appropriate safety precautions. Therefore, it is true that you should use an MSDS whenever you need additional information about a hazardous material that is not included on the product label.

Material Safety Data Sheets (MSDSs) are important documents that provide detailed information about hazardous materials, including their properties, handling procedures, and safety precautions. They are typically created by the manufacturer or supplier of the material and are essential for ensuring the safe and proper use of hazardous substances. Therefore, it is true that MSDSs should be referred to whenever detailed information is needed on any hazardous material.

The given statement is false because the most common types of physical hazards are actually slips, trips, and falls, followed by cuts and lacerations. While fire, inhalation, and chemical reactivity can certainly be physical hazards, they are not the most common ones.

Liquid flammables ignite more easily than liquid combustibles because they have a lower flash point, which is the lowest temperature at which a substance can vaporize and ignite when exposed to an ignition source. Flammables have a flash point below 100°F, while combustibles have a flash point above 100°F. This means that flammables can ignite at lower temperatures, making them more easily ignited than combustibles.

Flammables should not use an explosive symbol because although they can catch fire easily, they do not have the potential to explode or produce an explosive reaction. Flammable materials can ignite and burn when exposed to a flame or spark, but they do not have the same level of reactivity as explosive materials. Therefore, using an explosive symbol for flammables would be misleading and could lead to confusion or misinterpretation of the hazard.

Organic peroxides should use a Flaming "O" symbol because they are highly flammable substances that can easily ignite and cause fires. The Flaming "O" symbol is used to indicate materials that have an oxidizing property, meaning they can provide oxygen to support combustion. Organic peroxides contain a peroxide group (-O-O-) which makes them highly reactive and prone to decomposition, leading to the release of oxygen and increasing the risk of fire. Therefore, the Flaming "O" symbol is necessary to alert people to the potential danger associated with handling organic peroxides.

Gas cylinders are designed to store gases under high pressure. This is done to increase the amount of gas that can be stored in a limited space. The high pressure allows for the gas to be compressed and occupy a smaller volume. When the gas is released from the cylinder, it expands and can be used for various purposes. Therefore, it is true that the gas in a gas cylinder is stored under great pressure.
