Delayed Rescue Response Cited in Fatal Tunnel Fire

Thursday, September 02, 2010

Here’s another deadly reminder of the importance of a capable and timely response to confined space emergencies. Five people were killed in this fatal tunnel fire. According to OSHA, the case involving Xcel Energy and RPI Coating is not being tried until next year. After reading the official Chemical Safety Board report, here are some key findings…

    1. Did not have adequate technical rescue services standing by at the Permit Required Confined Space.       “911″ was listed on paperwork. Took the rescue team 1 hr and 15   mins to arrive at the site.
    2. Confined space was assessed as Non-PRCS even though the inability to self rescue and the introduction of MEK.
    3. RPI did not have an adequate confined space program.
    4. No hazard analysis was conducted.
    5. Not recognizing that 10% LEL or higher is an IDLH condition.
    6. Workers were located over 1400 ft away from where atmospheric monitoring was being performed.

DENVER – The U.S. Chemical Safety Board slammed Xcel Energy Inc. on Monday for the company’s handling of the aftermath of a tunnel fire that killed five workers at a hydroelectric plant, as well as for a host of “troubling episodes.”

The board cited the electric and gas utility’s failure to cooperate in the agency’s probe and said that investigators had to turn to the U.S. Attorney’s Office Civil Division in Denver to compel the company to turn over information. “Xcel Energy believes it has always cooperated and acted responsibly and continues to be fully committed to safety as a core value and an operational priority,” the company said in a statement.

The board, an independent federal agency that investigates serious chemical accidents and makes safety recommendations, plans to release its final report and recommendations Wednesday. That report comes about two weeks after Xcel decided to release a draft version after initially trying to block it. The company feared it would be released close to the criminal trial in the case, possibly influencing jurors.

Xcel, contractor RPI Coating and RPI executives Philippe Goutagny and James Thompson each are charged with violating U.S. Occupational Safety and Health Administration standards. They’re expected to go on trial next year. The safety board said the report wasn’t complete that it had instructed Xcel to keep the draft confidential. Xcel also said it wanted to release the draft report because the company wanted to show that the board excluded findings of a gap in OSHA standards.

Xcel and the board are at odds over whether OSHA regulations were sufficient or clear enough to ensure worker safety. The board says the utility should have had a specially trained rescue crew on-hand in emergencies, rather than calling 911 as directed by Xcel’s plan. The tunnel fire started when flammable vapors ignited on a machine that was being used to spray a coat of epoxy sealant on a portion of a 4,000-foot-long water pipe, trapping five of nine workers inside the pipe.

Specially trained rescue crews didn’t arrive until an hour and a half after the fire started. Donald Dejaynes, 43, Dupree Holt, 37, James St. Peters, 52, Gary Foster, 48, Anthony Aguirre, 18 – all from California – ultimately died from smoke inhalation.

In the letter sent Monday to Xcel CEO Richard Kelly, the board said Xcel’s “unprecedented” legal action to block the report delayed its release and diverted resources from other investigations. “In the wake of the corporate responsibility concerns raised by the Big Branch Mine accident in West Virginia and the disaster in the Gulf of Mexico, I strongly urge Xcel to renew its focus on safety and to swiftly implement the CSB’s recommendations,” wrote Chairman Rafael Moure-Eraso.

How much training is needed for attendants on air monitoring equipment?

Wednesday, September 01, 2010

Reader Jeff Machen had a question concerning how much training to give attendants on air monitoring equipment; especially when they may only be working a week long shut down? Here’s our reply from CSRT Manager Bryan Rogers.

When you’re dealing with temporary labor, it is difficult to ensure that they are well trained on something as complex as atmospheric monitoring. We checked with several equipment manufacturers, and they don’t set a specific amount of training required, but leave it up to the customer’s internal company policy and/or person(s) issuing the monitor.

We also spoke to a few of our instructors who work at different plants and refineries. The majority of these companies require a company employee to perform the initial monitoring and then again after a break in work greater than 30 minutes. In addition, they review with the attendant what to look for and what to do if there are changes in the readings or an alarm sounds. One company provides a four-hour PowerPoint presentation on monitoring and attendant responsibilities.

OSHA does not indicate a time frame for this training either. However, it does require that persons be capable of safely performing the tasks assigned. Therefore, I would say your best bet would be to cover as much of the manufacturer’s instructions as possible along with reviewing the most common problems such as…

    - Calibration conversions
    - Turning on the monitor (or “field zeroing”) in the presence of contaminates
    - Negative LEL or negative toxic readings
    - Contaminated sampling hoses
    - Clogged filters

Lastly, I would stress to the attendants the importance of contacting a supervisor if they have any questions or concerns - and, if they get any unusual results from the monitor… “Do not hesitate to have everyone exit the space while the results are investigated!”

Why does my Petzl ID snag and prevent me from taking up slack to the load prior to a lower?

Thursday, August 26, 2010

"Most likely the loaded section of the line is catching on the anti-error catch where the load line enters the body of the ID. This is a safety feature of the ID to prevent free-falling loads if the ID is loaded backwards. To prevent the rope from jamming, consider positioning yourself between the ID and the load facing the anchor. Hold both sections of rope oriented towards the load. Pull on the left section of rope while allowing the right section to drag through your hand. This will keep the rope clear of the anti-error catch." ~Roco Chief Instructor Pat Furr.

Why does my trusty old Petzl ID allow rope to continue feeding during a lower or rappel even after I have locked it off in work positioning mode?

Wednesday, August 25, 2010

The answer may be in the description “trusty old”. The ID has a wear indicator cast into the friction bobbin. It is located at the top of the bobbin on the side of the bobbin that the swinging side plate is on. When in usable condition the wear indicator is visible as a slightly raised ridge about a half-inch long. If the wear indicator is not visible the bobbin is worn out and the ID needs to be taken out of service.
