What do the colors mean in the ERG?

What do the colors mean in the ERG?

The ERG is divided into sections, each with its own color. The typical starting point is looking up a substance by name (blue pages), ID (UN) number (yellow pages) or image (placard, rail car, trailer). YELLOW: The yellow pages list chemicals in numerical order based on their assigned ID number (UN number).

Which ERG section contains distance information?

The third section, with blue page borders, references the material in alphabetical order of its name and identifies the appropriate guide number to reference in the Orange Section). Items highlighted in green in this section will also have evacuation distances included in the Green Section.

What is the blue section of the ERG?

Blue: In the event that the material’s UN number cannot be retrieved or is not readily available, the blue section, which lists chemicals by name in alphabetical order should be used. As is the case with the yellow section, highlighted materials indicate a toxic inhalation hazard or water reactive substance.

Where in the ERG can you find initial isolation distances and protective action distances?

green section

Are isolation distances greater at night?

Why are the recommended distances longer at night? The Dept. During the night, the air is generally calmer and this causes the material to disperse less and therefore create a toxic zone which is greater than would usually occur during the day.

What is the initial isolation distance?

The initial isolation zone is listed as 100 feet (0.03 km) for small spills and 800 feet (0.24 km) for large spills.

How far should you isolate the spill in all directions?

Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

What is protective action distance?

Table 1 – Initial Isolation and Protective Action Distances suggests distances useful to protect people from vapors resulting from spills involving dangerous goods that are considered toxic by inhalation (TIH).

What is a protective action zone?

The Protective Action Zone defines an area downwind from the incident in which persons may become incapacitated and unable to take protection and/or incur serious or irreversible health effects. Protective action distances are found in the greenbordered pages of the ERG.

What is the least reliable identification method and poses the highest risk for exposure?


What does the A stand for in the evade acronym?

Litmus paper. What does the A stand for in the EVADE acronym? Assist victims cautiously.

What does R stand for in ERG?


What is the first step after determining that a hazardous material is present?

What is the first step after determining that a hazardous material is present? Establish control of the scene. Once you have determined that a substance is leaking from a container, what should you do next? Isolate the material.

What is it called when there is not enough fuel in a fuel air mixture?

What is the temperature at which a flammable liquid will ignite without the need for an external ignition source? Ignition temperature. What is it called when there is not enough fuel in a fuel/air mixture? Too lean.

How do you fix a rich fuel mixture?

You can apply these methods described here to fix the rich mixture problem:

  1. Check The Air Duct’s Flap. The flap inside the air duct is an actuator that serves as choke.
  2. Vacuum Lines And Hoses.
  3. Clean The Mass Airflow Sensor.
  4. The Oxygen Sensor.
  5. Change the spark plugs.

How do I know if my fuel mixture is too rich?

When a car is running rich, it means the engine is receiving too much fuel and too little air. Your car will still crank and drive if it’s running rich, but you’ll likely experience symptoms like low gas mileage, slow acceleration and strong smell of gasoline (especially when idling).

How do you fix air fuel mixture?

Make adjustments 1/2 a turn in either direction to find the smoothest idle speed. Turn the screw counterclockwise and clockwise 1/2 a turn from the middle position and listen to the sound of the idle. Set the screw in the position where the engine’s idle sounds most even and smooth to balance the fuel mixture.

Can running Rich damage engine?

Running rich is not good for the engine as it builds up carbon deposits on valves and pistons that destroy the engines performance.

What causes too rich fuel mixture?

A faulty oxygen sensor sending the wrong signal to the engine control module can result in a rich fuel condition. Symptoms of a rich fuel condition include black colored exhaust, fouled spark plugs, and poor engine performance.

How do I know if I am running lean or rich?

Signs Of Your Engine Running Lean

  1. 1: Bad Performance. Your car will have less power than it had before.
  2. 2: Car Won’t Start. Your may have trouble starting your car, or your engine may not turn over.
  3. 3: Spark Plugs Are Clean Or White.

Is it better to run an engine lean or rich?

Running lean can give you more power but to lean will blow your engine. Running too rich can also hurt your motor. Think of it when you are mixing gas for your weed wacker. It is always safe to add a little more oil than not enough to the mixture.

Is my engine running rich or lean?

But what is the difference between an engine running rich or an engine running lean? The expression running rich or lean is in reference to the amount of gas that you have in the engine. If there is too much gas, then you will be running rich, and if there isn’t enough gas, then you are running lean.

What happens when an engine runs lean?

In combustion engines, “running lean” goes beyond using gas efficiently. In effect, that status makes the engine perform with less gasoline than it needs to operate properly, and it increase the amount of friction between the engine’s moving parts. Running lean can damage an engine.

Which way is lean and rich?

When an air/fuel mixture has too much fuel, it is rich. When there is not enough fuel, it is lean. An AFR higher than stoich = lean. An AFR lower than stoich = rich.

How do I know if my carburetor is too rich or lean?

Typical symptoms of a rich mixture are:

  1. Poor fuel economy.
  2. Sluggish acceleration.
  3. Choke not needed from cold starts.
  4. Sooty or black spark plugs.
  5. Sooty or black muffler end pipes.
  6. Strong smell of gasoline when the machine is at idle.
  7. Uneven running (will often slow from regular idle rpms and then stop)

Is a bog lean or rich?

sicivicdude Member. But just for reference (for those who haven’t experienced both) a lean bog is a hollow “BOOOOGGGGGGGG” sound. A rich bog is a sputter stutter.

How do you adjust the air fuel ratio on a carburetor?

Once the engine has arrived at operating temperature, go back to the carburetor and adjust the air fuel mixture screw, or screws. Tightening the screw increases the amount of fuel, while loosening decreases the amount of fuel.
