Update: Friday 9/5 @ 6 p.m.

INSTITUTE, W.Va. (WSAZ) -- When it comes to the explosion at the Bayer CropScience plant, there are still more questions than answers.

A spokesperson for the company said they will sit down with metro 911 next week to talk about what worked and what didn't. But county leaders have made it clear that there was a massive communication failure.

WSAZ obtained a letter from the county to Bayer on Friday, claiming that Bayer told emergency crews from all over the western part of the county nothing in the crucial moments following last week's explosion.

Kanawha County Commission President Kent Carper said 12 pages of transcripts show Bayer gave little information.

On Friday, Bayer said, "We believe we established the correct communications with metro 911." Site manager Nick Crosby, however, won't give any specifics.

Carper called it a "complete abdication of Bayer’s responsibility to your neighbors and our first responders." Crosby said he is "somewhat surprised to see his (Carper’s) words and will take them into account."

Given several chances, Crosby would only say they established correct communications. He would not answer who they talked with at metro, who called from his plant or even why a guard was tying up an emergency line to give out information they claim they were giving off a recorded line.

One thing Bayer already has said it has learned is that there has clearly been a change in the public’s expectations of communications in these incidents.

UPDATE: Friday 9/5 @ 11:25am
Kanawha County Commission President Kent Carper sent a letter dated September 4 to Bayer Plant Manager Nick Crosby, criticizing the plant's communication with Metro 911.

In the letter, Carper says Metro 911 "repeatedly asked for information and was refused." He adds that the company did not provide information to the public in a timely manner.

"This was a complete abdication of Bayer's responsibility to your neighbors and our first responders, who were sent uninformed to an explosion because no one was 'allowed' to inform us," wrote Carper.

Carper included the transcripts of the 911 calls made to/from Metro 911 the night of the explosion.

On Thursday, Kanawha County Metro 911 released recordings of the calls between Bayer and the 911 center. The recordings start at 10:39 p.m. last Thursday after the explosion happened, and run through 5:50 a.m. Friday morning.

Call after call, a person who says he's a guard at the front gate at the Bayer Plant tells Metro 911 that there is an emergency at the plant and he hasn't been authorized to release any more information.

"My supervisor informed me to tell you to uh alert the community that there is an emergency uh in the plant right now," said the guard at Bayer.

Commissioner Dave Hardy calls the information provided by Bayer following the blast unacceptable. He says Bayer needed to let Metro know as much as possible so that the county could provide the proper response.

Late Friday, Bayer issued this statement about the recordings:

"We shared all available information with Metro 911 as that information became available over the course of the incident.

The transcripts of the calls to Metro 911 which were released today represent only a portion of the communication between Bayer CropScience and emergency response officials during this event.

A number of other contacts were made over the course of the event to the Office of Emergency Services, indicating the nature of the event and providing more details.

Further, there were several county and state emergency services representatives present in the Emergency Operations Center (EOC) at the Bayer CropScience Institute site. These personnel had full access to all information pertaining to the incident.

Also, when requested by Metro 911, we had two people from our site go to the mobile command center and had another liaison dispatched to the Metro 911 Operations Center on Corridor G.

We fully support and count on the 911 system and, together with the media, we count on them to carry important messages to the public.

We will continue to work with Metro 911 to improve our information flow. As part of this commitment, we will be actively participating with them in the critique next week."

We are continuing to add more information to this story as we dig through the data and talk with more county and Bayer officials. We will also add the recordings. Keep clicking on WSAZ.com for more information.

The chairman of the board, John Bresland, says the purpose is to make recommendations to the company, OSHA, the Environmental Protection Agency and the county about what can be done to keep an incident like this from happening again.

They'll examine the accident site and talk to employees and managers at the plant. Their recommendations will not be mandates for the company, but suggestions.

The board will hold public meetings on the findings.

Broken glass and caution tape are two signs that Thursday night’s explosion reached far beyond the confines of the Institute plant.

Jill Oliver of Oliver Oils and Fuels had some glass shattered at her business from the explosion, but knows what she lost can be replaced.

"I hated that that man lost his life," she said Friday, referring to Barry Withrow, the Bayer CropScience employee who was killed. "There is a family that is grieving the loss of a loved one right now."

Investigators said they will thoroughly sift through the scene to determine what happened.

"We will pull this apart with a toothpick and, until we can flush out the real cause of it, we are not going to start that unit again," said Nick Crosby of Bayer CropScience.

The unit is located on the west end of the plant. Crosby said there was no indication of trouble.

"It was running, it was producing product, it was normal," he said. "Things were progressing well."

But in a split second that changed. Flames started shooting at least 100 feet in the air when a chemical residue ignited.

"I know there was some concern about offsite air pollution," Crosby said. "We monitor the pollution, and we found no evidence of any chemicals or injuries or harm to people."

Crosby put things in perspective at a news conference Friday, saying that people are safer working inside their chemical site than they are crossing the road. Investigators from both the state and federal government are now investigating, and the investigation could take several days.

Metro also tells WSAZ.com that for the first time employees can remember, so many 911 calls came into the center that the lines were overloaded, causing some people to get a message saying, "all circuits are busy."

There was also a problem with the information line that Metro 911 set up at its emergency operations center (EOC) for residents to call in and ask questions. County officials tell us some sort of glitch caused only one line to work at one, causing most callers to get a busy signal. A phone technician had the problem repaired by about 3:00 a.m.

Officials say the 1993 explosion occurred during the initial part of the process, while Thursday night's explosion happened at the end part. They say the company spent millions of dollars to correct the 1993 problem, and will do the same to correct whatever caused the most recent explosion.

According to the news release, the CSB is an independent federal agency charged with investigating industrial chemical accidents.

State Department of Environmental Protection spokeswoman Kathy Cosco says that the chemical primarily involved in the fire was methyl isobutyl ketone.

Methyl isobutyl ketone, also called MIBK, is used in the production of the insecticide Larvin.

Cosco says the chemical isn't particularly toxic but highly flammable.

The company says air monitoring found no signs of chemical exposure, either on or off site.

Bayer also produces methyl isocyanate -- or MIC -- which killed at least 15,000 people in a leak in Bhopal, India, in 1984. But Petry said that chemical is stored in steel-wrapped underground containers located far from the blast site.

The explosion occurred at about 10:25 p.m. and could be felt miles away. The fire was extinguished at about 2 a.m.

The cause hasn't been determined.

Bayer says its last accident at that plant was at least two years ago.

Officials say the shelter in place was issued for precautionary reasons, and no toxic chemicals were released.

Chris says Barry was from St. Albans and worked at the plant for more than 20 years. Barry was working overtime Thursday night, according to Chris. The last time Chris spoke to Barry was Tuesday night while Barry was at work.

Bayer spokesman Mike Wey says the explosion occurred about 10:25 p.m. Thursday. The explosion, which witnesses say sent a fireball hundreds of feet into the air, ignited waste residue in a section of the plant that produces insecticides.

Wey says the injured worker suffered burns and was transferred to a Pittsburgh hospital for treatment. Wey said both workers are senior employees at the plant.

He said a search for the missing worker won't be conducted until the fire is extinguished.

The plant is located about 10 miles west of Charleston.

Crews are going to assess the situation before going in to look for the missing worker.

Wey confirms that one man was burned and is being taken to a burn center in Pittsburgh. Another worker is still missing. Wey says both have worked with the company for some time.

Wey says a waste product appears to be what exploded. It's a very flammable product. Wey says it was NOT Larvin. He says the product released to the area after the explosion is not toxic.

Eight operators were working in the area where the explosion happened--six of them were in a safe area and were not hurt.

Metro 911 says I-64 is closed in both directions near Institute. It's shut down in the west bound lanes at the Dunbar exit--and at the Nitro exit east bound.

Right now, there is now word about school Friday.

Anyone wanting more information should call the EOC at Metro 911: (304) 746-8828.
