It is necessary for the sales manager to fully understand the customer’s company nature, usage needs, and actual operating environment during the conversation.
Below, I will briefly introduce the different characteristics of various types of Isuzu fire trucks, so as to facilitate answers for customers.
Isuzu fire trucks are mainly used for fire fighting operations, so we classify them from the source of fire:
Class A fire source: Also known as Class A fire source, it is an ordinary solid combustible fire. Such as wood products, plastic products, coal, fibers and so on.
Its characteristic is that it burns as a whole, and it can be put out with ordinary water, but the inside must also be put out. If only the surface is extinguished, the residual fire inside will reignite again.
It is the most common fire in urban communities, and the most conventional Isuzu water tank fire truck can be used.
Class B fire source: Also known as Class B fire source, it is a flammable liquid or soluble solid fire. Such as petroleum gasoline diesel, paint alcohol and so on.
Although such sources of ignition only burn on the surface, they are generally explosive. It is characterized by fast burning speed, high temperature and easy explosion.
It is the most prone to fire in chemical enterprises, wharf ports, cruise tankers, etc.
In this case, it is generally necessary to use Isuzu dry powder fire trucks and Isuzu foam fire trucks to fight, but water tank fire trucks cannot be used. Because oil is lighter than water, it floats and spreads on water.
Class C fire source: also known as Class C fire source. Refers to combustible gases, such as liquefied natural gas and various combustible gases.
This type of fire is characterized by flammable and explosive, extremely fast burning, and high explosive power. An Isuzu dry powder fire truck is required.
Class D fire source: also known as Class D fire source, which refers to the fire of combustible metals, such as potassium, sodium, lithium and other metals.
The burning characteristics of this type of fire are extremely high temperatures, and it is necessary to use Isuzu dry powder fire trucks to put out the fire. Water tank fire trucks containing water and foam fire trucks cannot be used.
In addition: electrical fire itself is not a separate item. If the power can be cut off, it can be put out according to Class A. If the power cannot be cut off and the fire is carried out under the condition of power on, only dry powder fire trucks that do not contain moisture can be used to carry out the fire. save.
The common fire sources are the above types. You can consider ordering Isuzu fire trucks according to your own needs.
