-What is the hazardous materials handler test?

There are three types of hazardous materials handler tests: Class A, Class B, and Class C. Since the range that can be handled is limited, many people aim to acquire the qualifications of Class A and Class B.

If you pass the class A, you can handle all dangerous goods stipulated in the Fire Service Act, but you need to be qualified to take the examination (for example, you have obtained a certain number of credits in the department of chemistry at the university).

Class B has the same qualifications as Class B, which is classified as Dangerous Goods, and can handle Dangerous Goods of the passed class. Since Type B does not require an examination qualification, the number of examinees tends to increase.

-About Dangerous Goods Class B-4-

The more dangerous goods B class is synonymous with class 4, the more people take the class B class 4. Class 4 dangerous goods learned by studying for Class B 4 exams are said to account for about 80% of all dangerous goods, and you will be able to handle familiar dangerous goods such as gasoline, light oil, and kerosene.

Gasoline has a strong image of a gas station, but it is also popular because it can be used in many workplaces such as chemical manufacturers, research institutes, and firefighters.
The test subjects of Class B 4 are as follows.

[Examination subject]
1. 1. Laws and regulations regarding dangerous goods 15 questions
2. 2. Basic physics and basic chemistry 10 questions
3. 3. The nature of dangerous goods and their fire prevention
And how to extinguish a fire 10 questions

The exam time is 2 hours, and the passing standard is to score 60% or more of all subjects. To put it the other way around, it is important to note that if even one subject has a score of less than 60%, it will be rejected. The test method is a mark sheet type written test, which is a five-limb alternative (choose one of the five options that is appropriate).

-Pass rate of Class B 4 test-

First of all, the pass rate for Class B Class B, a hazardous materials handler, is about 30%. Class B 1,2,3,5,6 is as high as about 65%, but only Class B 4 stands out and the pass rate is low.

Looking at this data alone, it seems that Class B 4 is more difficult than other Class B tests, but that is not the case. As mentioned in the section "Dangerous Goods Class B 4", those who do not intend to pass the exam seriously because Class B 4 is so popular, or those who do not intend to accept it but are accepted at companies, vocational schools, etc. There are many cases, and the passing rate is low because such people take the exam, so it is not particularly difficult for Class B 4 compared to other Class B exams.

~ Schedule of this application ~

As for the learning flow of this application, we will proceed in the order of physics / chemistry, fire extinguishing, and laws in the first half. From the second half, we will study three genres in parallel and try to establish them.

In the latter half of the study, take a mock exam as appropriate to understand your ability. I think that there are many people who are hampered by physics / chemistry or laws and regulations. For genres that you are not good at, please use the stock function for each genre to study.

In the hazardous materials handler examination, it is necessary to score 60% or more in all genres, so be sure to eliminate your weaknesses.

-This is different from other learning tools-

1. 1. You can do practice tests many times

The biggest feature of this application is that you can perform a mock exam that randomly selects a question from about 700 questions each time.

Usually, when studying with books, the order of the questions is the same every time, and it becomes difficult to understand your own ability.

With this app, you can perform different tests as many times as you like, and you can accurately measure your own ability.

2. 2. Stock function of problems that I am not good at

If you solve a problem repeatedly, you will end up with a problem that you will make mistakes over and over again. With this app, if you find a problem that you are not good at while solving a mock exam or a genre-specific problem, you can stock the problem.

In stock learning, you can solve only the stocked problems and support the overcoming of weak problems.
