A massive fire emitting toxic smoke from an eastern Indiana recycling plant described by the city’s mayor as a known “fire hazard” has forced evacuation orders for about 2,000 people as the battle to put it out is expected to drag on for days, city and state officials said.
Plastics were among the items that started burning Tuesday at the Richmond plant, and the smoke – a thick, black column that rose from the site – is “definitely toxic,” Indiana State Fire Marshal Steve Jones said in a news briefing.

News flash, all smoke is toxic. Even regular wood offgasses hydrogen cyanide.
Don't be so worried about phrasing.

There are different levels of toxicity depending on whats burning. Plastic, which is burning at the plant is likely more toxic than a wood fire. True or False

You breathe a lot of wood smoke, you die.
You breathe a lot of plastic smoke, you die.
The level of death is the same.
"He's dead, Jim."
"Would that be dead from wood smoke or dead from plastic smoke?"
He'd dead either way, Jim."

The greatest concern for emergency responders, and particularly firefighters, is the burning of plastics. All plastics that contain carbon will burn. As with any materials that will burn, some are more combustible than others.
Chemicals can be combined with plastics during manufacture to reduce combustibility. Other plastic materials are formulated to be self-extinguishing. Plastics that contain carbon and hydrogen - such as polyethylene, polypropylene, polybutylene and polystyrene - burn very well. Burning polyethylene melts, smells like wax and produces dripping of the melted flaming material that could spread the fire. Polystyrene burns much slower, producing large soot particles, and smells like vinegar. Styrene is an aromatic hydrocarbon and they, as a family, burn sooty with incomplete combustion.
Plastics that are composed of carbon, hydrogen and oxygen burn slower than the others mentioned. Thermosetting plastics can produce burning smells like charred wood or formaldehyde. Those plastics that contain nitrogen and sulfur will produce very toxic gases when they burn. Plastics containing nitrogen burn with no smell, and those with sulfur produce a choking sulfur dioxide smell.
Manufacturing Plastics
The process of making plastics involves many different compounds and hazardous materials that are commonly shipped in transportation and stored in manufacturing facilities. One of the most common compounds used in the making of plastics is the monomer. Monomers can be found as solids, liquids or gases. Ethylene, which is used to make polyethylene plastic, is a colorless gas with a sweet odor and taste. It is also a highly flammable gas with a wide flammable range of 3%-36% in air. It is not considered toxic, but can displace oxygen in the air and create an asphyxiation hazard to response personnel.(Ethylene is also the gas that is produced naturally by ripening fruit and is used in orchards to hasten fruit ripening.)
Styrene is another monomer from the aromatic hydrocarbon family, along with benzene, toluene and xylene. Also called vinylbenzene, it is a colorless, oily, aromatic liquid. Styrene is a moderate fire risk with a narrow flammable range of 1.1% to 6.1% in air. It is toxic by ingestion and inhalation and has a threshold limit value (TLV) of 50 parts per million (ppm) in air. Styrene monomer is used to make polystyrene, which is the rigid plastic from which soft-drink-cup covers are made. Polyacrylamide, a solid mono-mer white in color, is used to make the clear plastic from which compact discs are made.
Butadiene is another common, but dangerous monomer. It is a gas that is highly flammable and has a flammable range of 2%-11% in air. Butadiene is also a suspected carcinogen and has a TLV of 10 ppm in air. It is used in making elastomers and neoprene.
Monomers cannot be shipped or stored unless they have been stabilized through the use of an inhibitor. The inhibitor prevents the uncontrolled polymerization of the monomer during transportation and storage. It does not interact chemically with the monomer, it just acts as a stabilizer. U.S. Department of Transportation (DOT) regulations prohibit the transportation of most monomers without the material being inhibited.

First , one would have to review the levels of toxicity and concentration before one would be able to answer that .
A little dab of plastic will do ya .
Please think before you post .

Is this the explosion that killed 80,000 dairy cows?
