What is the NFPA for diesel fuel?

What is the NFPA for diesel fuel?

NFPA 124: Standard for Fire Protection of Diesel Fuel and Diesel Equipment in Underground Mines.

What is the LEL of diesel fuel?

0.6 percent to 1.3 percent
The LEL concentration of diesel fuel ranges from 0.6 percent to 1.3 percent volume in air. This is equivalent to 6,000 to 13,000 ppm. This means it takes a minimum concentration of between 60 and 130 ppm of diesel fuel vapor to produce even a 1.0 percent LEL reading!

What kind of hazard is diesel fuel?

Irritant Potential. Diesel fuel is a skin and eye irritant that can cause rashes and reactions when exposed to human skin. Long-term exposure to diesel fuel is also connected to skin cancer and disorders within the central nervous system.

How is NFPA 704 rating calculated?

The picture below shows NFPA rating criteria and a typical NFPA 704 label. Different colors represent different types of hazards. A number rating system of 0-4 is provided to rate each of the four hazards and is placed on a placard. 0 represents the least hazardous while 4 represent the most hazardous.

Can diesel vapors ignite?

Diesel vapors can ignite and explode when mixed with air. The lower explosive limit is less than 1%, and the upper explosive limit is about 10%. That means that diesel fuel vapors from a storage tank can explode with as little as 1% of the air being diesel fuel vapors.

What chemicals are in diesel?

Chemical composition In the United States, petroleum-derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes).

Is there benzene in diesel fuel?

Diesel exhaust consists of a complex mixture of chemicals which contain known genotoxicants, one of which is benzene. The particulate matter contained benzene in amounts comparable to those usually found for concentrations of carcinogenic polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs.

What does NFPA 704 stand for?

“NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response” is a standard maintained by the U.S.-based National Fire Protection Association.

What is SA on NFPA 704?

The NFPA 704 standard of the National Fire Code provides a simple system for identifying hazards associated with various materials in case of a fire, spill or other emergency. This surface-mount NFPA diamond with 3-0-0-SA rating will help alert emergency responders to potential danger.

Can diesel be burnt?

While they can both be a fire hazard, only gasoline is technically a flammable liquid. Diesel is instead classified as a combustible liquid. But make no mistake about it, diesel can and will burn. It can fuel fires and be very dangerous in certain conditions.

Can diesel tank explode?

That means that diesel fuel vapors from a storage tank can explode with as little as 1% of the air being diesel fuel vapors. If the tank contains diesel vapors, a welding arc can easily cause an explosion.

What are the 3 types of diesel?

Diesel fuels are broken up into 3 different classes: 1D(#1), 2D(#2) and 4D(#4). The difference between these classes depends on viscosity (the property of a fluid that causes a resistance to the fluid’s flow) and pour point (the temperature at which a fluid will flow). #4 fuels tend to be used in low-speed engines.

What to know about NFPA 704 signs?

There are three symbols approved by the NFPA 704 system: W – The W symbol indicates that the chemical being labeled has a strong reaction to water. OX – This symbol indicates that the chemical will have a violent reaction if exposed to oxygen. SA – SA is a symbol for simple asphyxiate gases.

What do the areas of the NFPA 704 markings indicate?

The National Fire Association (NFPA) has developed a color-coded number system called NFPA 704. The system uses a color-coded diamond with four quadrants in which numbers are used in the upper three quadrants to signal the degree of health hazard (blue), flammability hazard (red), and reactivity hazard (yellow).

What is the NFPA 704 fire diamond?

The “Fire Diamond” or “NFPA 704” refers to signs posted at locations that contain hazardous materials . The purpose of the signs are to alert emergency personnel to the risks posed by the materials.
