A level Operation intervenor is not able to wear chemical protection equipment and intervene directly at the source of the problem.

The acronym CBRN-E stands for Chimique (Chemical) - Biologique (Biological) - Radiologique (Radiological) - Nucléaire (Nuclear) - Explosif (Explosive). This acronym is used to classify and address threats related to chemical, biological, radiological, nuclear, and explosive materials or events.

The correct answer is NFPA 704. NFPA 704 is a standard developed by the National Fire Protection Association (NFPA) that provides a system for identifying the hazards associated with different chemicals. It uses a diamond-shaped label with the colors red, blue, yellow, and white to indicate the level of health, flammability, instability, and special hazards of a particular substance. This system is commonly used in industrial settings and emergency response situations to quickly convey important information about the potential dangers of a substance.

The correct answer is A-B-C-D. This answer lists the four levels of chemical protection in order. Level A provides the highest level of protection, including a fully encapsulated suit with self-contained breathing apparatus. Level B provides a lower level of protection, with a chemical-resistant suit and an air-purifying respirator. Level C provides a still lower level of protection, with a chemical-resistant suit and a full-face respirator. Level D is the lowest level of protection and consists of basic work clothes with no respiratory protection.

Malgré que ce type de contenant contienne plus de 200 litres de produit (208 litres), il est considéré comme un petit
contenant.

L'explication pour la réponse correcte "Zone de refuge" est que c'est l'endroit où les victimes doivent être rassemblées en attendant que les lignes de décontamination soient installées. Cela implique que la zone de refuge est un endroit sûr où les victimes peuvent se mettre à l'abri en attendant les mesures de décontamination nécessaires.

Propane is the correct answer because it has a boiling point of -42°C, a fusion point of -189.7°C, a solubility of 0.007g/100 ml, a vapor pressure of 840 kPa, a vapor density of 1.6, a flash point of -104°C, an auto-ignition temperature of 450°C, and a lower explosive limit (LEL) to upper explosive limit (UEL) range of 2.1%-9.5%.

La citerne numéro 4 contient de l'éthanol identifié par le NIP 1170.

The correct answer is BLEVE, which stands for Boiling Liquid Expanding Vapor Explosion. When a propane bottle is heated by flames, the liquid propane inside can rapidly boil and create a large amount of vapor. This can cause a rapid increase in pressure, leading to an explosion. A BLEVE can be extremely dangerous and destructive, posing a significant risk to anyone nearby.

A combustible liquid is a liquid that does not fit the definition of any other class of risks and has a flash point that is higher than 60.5 degrees Celsius but lower than 93 degrees Celsius.

The statement is false because the transportation of dangerous goods is subject to regulations, but the storage of dangerous goods is subject to different regulations. Therefore, the statement is incorrect.

The solid must be transported at a temperature of 240 degrees Celsius or higher in order to be identified using the high-temperature material plate.

Propane has a lower explosive limit (LEL) than acetylene, meaning that it requires a lower concentration in the air to become explosive. This indicates that propane is more volatile and poses a higher risk of explosion compared to acetylene.

The correct answer is 2-4-3. This is because the NFPA 704 markings indicate the level of health, flammability, and reactivity hazards of a substance. In this case, the highest risk of fire would be represented by a flammability rating of 4, which is indicated by the first number in the answer choice. The second number represents the health hazard, and the third number represents the reactivity hazard.

The given correct answer is "Proteger." This answer suggests that the question is asking to identify the forms or types of recommended protection zones. It implies that the question is related to identifying the different ways or methods of protecting something. However, without further context or information, it is difficult to provide a more specific explanation.

It is not permitted to place a DANGER sign on a trailer when it is transporting materials from classes 1, 3, and 5 at the same time.

The shape of the cistern, the presence of a plaque, and the name of the product displayed on the cistern are all indicators that can help identify the presence of dangerous materials in the photo. The shape of the cistern may suggest that it is specifically designed to transport hazardous substances. The presence of a plaque could indicate that the cistern contains dangerous materials and provides necessary information about them. The name of the product displayed on the cistern can also be a clue, as certain products are known to be hazardous.

The correct answer is "inférieur ou égal à 60,5 celsius". This is because a flammable liquid is defined as a liquid with a flash point equal to or below 60.5 degrees Celsius. The flash point is the temperature at which the liquid can emit enough vapor to ignite in the presence of an ignition source. Therefore, any liquid with a flash point at or below 60.5 degrees Celsius is considered flammable.

If magnesium-aluminium phosphide is poured at night and comes into contact with water, it will release phosphine gas.

Acétone is the correct answer because it has a boiling point of 56°C, a melting point of -95°C, it is miscible in water, it has a vapor pressure of 24 kPa, a vapor density of 2.0, a flash point of -18°C, an auto-ignition temperature of 465°C, and a lower explosive limit (LEL) of 2.2% and an upper explosive limit (UEL) of 13%.

Méthane is the correct answer because it has the lowest boiling point (-161°C) compared to the other options. The boiling point is the temperature at which a substance changes from a liquid to a gas, and since methane has the lowest boiling point, it will vaporize at a lower temperature compared to the other substances.

The correct answer is L'oxygene, Sulfure d'hydrogène, La présence d'un gaz inflammable, Monoxyde de carbone. These are the four elements measured by a "détecteur 4 gaz" (4 gas detector). The detector is designed to measure the levels of oxygen, hydrogen sulfide, the presence of any flammable gas, and carbon monoxide.

When the LIE (LEL) reaches a certain percentage, actions to control the risk must be implemented. In this case, the correct answer is 25%. This means that when the LIE (LEL) reaches or exceeds 25%, it is necessary to take measures to control the risk.

Ammoniac anhydre has a boiling point of -33 °C, which means it will vaporize and turn into a gas at temperatures above -33 °C. This is supported by its high solubility of 54g/100 ml, indicating that it readily dissolves in water. Additionally, the high tension de vapeur of 1013 kPa suggests that it has a high vapor pressure, meaning it will easily evaporate into the air. The low density de vapeur of 0.59 further confirms its tendency to form a gas. Therefore, Ammoniac anhydre is the correct answer.

The correct answer is Isocyanate de méthyle. Based on the given information, the boiling point, melting point, solubility, vapor pressure, vapor density, flash point, and auto-ignition temperature do not match the properties of Ammoniac anhydre, Propane, or Acétylène. However, the properties listed align with Isocyanate de méthyle, making it the correct answer.
