Preparing for the Chemical NEP

Mar 23, 2010
Mark S. Dreux
On July 27, 2009, OSHA issued a National Emphasis Program for the chemical industry (“the Chemical NEP”). Pursuant to the Chemical NEP, OSHA will conduct PSM inspections of numerous chemical facilities. This presentation will review lessons learned from OSHA's Refining NEP, particularly the OSHA...

Gas Piping and Equipment Commissioning Risks "10 Key Things Everyone Should Know"

Mar 23, 2010
John R. Puskar
There have been a number of devastating incidents related to natural gas piping system and the start-up and commissioning of equipment. It's very rarely that an incident occurs when equipment is at the ready and in some normal operating routine. The vast majority of incidents are directly related...

Complying with OSHA's RNEP, CNEP, and VPP RAGAGEP

Mar 23, 2010
Chad Patschke
The OSHA Refinery National Emphasis Program (NEP) and OSHA Voluntary Protection Program (VPP) PSM Supplement ask specific questions relative to many recognized and generally accepted good engineering practices (RAGAGEP). Many of the same RAGAGEP can be expected in the planned OSHA Chemicals NEP as...

Condensation Induced Water Hammer: Principles and Consequences

Mar 23, 2010
Carlos A. Barrera
An explosion occurred in the boiler room of a food processing plant as the steam generation system was coming online after a maintenance shutdown. The explosion shattered the case of the condensate return pump fatally injuring an employee, while another employee was burned by the escaping steam...

Imperial Sugar Refinery Combustible Dust Explosion Investigation

Mar 23, 2010
John Vorderbrueggen
On February 7, 2008, at about 7:15 p.m., a series of sugar dust explosions at the Imperial Sugar manufacturing facility in Port Wentworth, Georgia, resulted in 14 worker fatalities. Thirty six workers were treated for serious burns and injuries—some caused permanent, life altering conditions. The...

Near-Miss Management to Develop Dynamic Leading Indicators to Predict Incidents

Mar 23, 2010
Ankur Pariyani
Recent studies have shown the importance of identifying near-misses to predict the probability of accidents (Meel and Seider, 2006) – and managing them to reduce the potential of accidents (Phimister et al., 2003; Cooke and Rohleder, 2006). In this paper, new methodologies involving near-miss...

Burn Injury Caused by Mixing Incompatible Chemicals with Sodium Permanganate

Mar 23, 2010
Russell A. Ogle
This paper discusses the investigation of an accident caused by the mixing of incompatible chemicals, a strong oxidizing agent with a reducing agent. The exact mixture and sequence of mixing was unknown, but the materials included an aqueous solution of 40% sodium permanganate (NaMnO4) and possibly...

Modification of Risk Using Barrier Methodology

Mar 23, 2010
Robin Pitblado
Risk assessments use frequency data mostly from generic sources, typically from the North Sea offshore environment or from process facility records mainly from Europe. As QRA's are being applied increasingly in North America and in the developing world, novel techniques are necessary to establish...

Elements of Human Factors Missing from Process Safety

Mar 23, 2010
Revonda Tew
Process safety is about controlling risk of failures and errors; controlling risk is primarily about reducing the risk of human error. All elements of Risk-Based Process Safety (RBPS) and alternative standards for process safety (such as US OSHA's standard for Process Safety Management [PSM] or ACC...
