Here's an example of the type of incidents reported and analyzed on our PHAs and PSM pages (see links at upper left of all first pages).

In 2003 there was an explosion and fire at the CTA Acoustics plant in Corbin, KY. Combustible dust in the plant ignited according to investigators of the U.S. Chemical Safety and Hazard Investigation Board (CSB).

The Feb. 20, 2003 incident took seven lives and caused over thirty injuries.

An initial explosion and fire occurred on a production line that was partially shut down and being cleaned at the time of the incident. During the cleaning, a thick cloud of dust dispersed around the line. The dust was likely ignited by a fire that spread from the production line's oven, which was still operating, investigators said. "The plant's four production lines had a history of small fires erupting in the ovens," said lead investigator Bill Hoyle. "Plant operators routinely put out these fires. However, during the cleaning operation, no one was present in the immediate area of the oven who could have detected a fire."

  NST/Engineers makes use of a core staff having a combined industrial experience of over 100 years. The core staff performs the functions of project management, OSHA required safety training, cost estimating, scheduling, cost control, site supervision, and documentation. Their experience, and that of associates, is especially broad with respect to work in a wide range of services and training areas, industries, materials, and processes.

  Some services areas examples are: HAZWOPER, and more, safety training to satisfy OSHA requirements; process safety and site inspections for OSHA compliance; brownfields site investigations and remediation; remediation "Cost Cap" insurance project plans; waste treatment engineering; air pollution control designs, and plant equipment startup, operating, preventive maintenence, and safety instructions.

  Materials experience includes: surfactants and detergents; rayon; propellants; hazardous wastes, lead, asbestos; PCBs, pesticides, and other ‘refractory’ organics;industrial gases, hydrogen, helium, oxygen, nitrogen, and argon.

  Our process experience includes: absorption, adsorption, combustion, extraction, filtration, gas scrubbing, hazardous waste site remediation, oxidation, ozonation, polymerization, sulfonation, and spray drying.

For a fee-based consultation call with a Licensed Professional Engineer between 3:00pm and 5:00pm Eastern Daylight Time, call (302) 239-2700.
