Several months ago SafetyAtWorkBlog reported on the outcomes of a dust exploion in a sugar factory in the United States. The ICIS Radio podcast for 6 October 2008 provides the latest information on dust explosions as well as a good update on OHS issues in the chemical industry.
It is clearly a promotion for ICIS Magazine but it is a good short news podcast.
Last month America’s 60 Minutes broadcast an article on the explosion at the Imperial Sugar plant (pictured below) in Port Wentworth which killed 13 workers and hospitalised 40. On 25 July 2008, the Occupational Safety and Health Administration (OSHA) issued citations proposing penalties totalling $8,777,500 against the Imperial Sugar Co. and its two affiliates alleging violations at their plants in Port Wentworth and Gramercy.
The US Chemical Safety Board (CSB) has released some details about its appearance at the US Subcommittee on Employment and Workplace Safety, Senate Committee on Health, Education, Labor, and Pensions, on 29 July 2008. (Transcripts and video are available HERE)
CSB Chairman John Bresland said the tragedy demonstrates the need for a new OSHA standard that would cover a range of industries exposed to this hazard, such as food, chemicals, plastics, automotive parts, pharmaceuticals, electrical power (where generated by coal) and others.
According to the CSB, Chairman Bresland told the subcommittee, chaired by Sen. Patty Murray of Washington,
‘After witnessing the terrible human and physical toll from the Imperial explosion, I believe the urgency of a new combustible dust standard is greater than ever. A new standard, combined with enforcement and education, will save workers’ lives.’
‘We obtained documents indicating that certain parts of Imperial’s milling process were releasing tens of thousands of pounds of sugar per month into the work area. Based on our evidence, Imperial did not have a written dust control program or a program for using safe dust removal methods. And the company lacked a formal training program to educate its workers about combustible dust hazards.’
Bresland emphasised the need for a uniform Federal standard:
‘Instead of the present patchwork of miscellaneous federal, state, and local requirements, the Chemical Safety Board has recommended that OSHA develop a single, comprehensive, uniform standard – based on the sound, consensus-based technical principles and practices that are embodied in NFPA standards,’ Chairman Bresland said. ‘Ambiguities in the NFPA standards need to be resolved in clear, enforceable regulations developed by a thorough, public rulemaking process.’
On 8 June 2008, a US 60 Minutes report on combustible dust joined the conga-line of critics of the Occupational Safety And Health Administration. The tone of the report is set by the reporter, Scott Pelley’s introduction stating that it is OSHA’s responsibility to avoid the explosions. For OHS practitioners and professionals this is a peculiar statement as it is usually the employer’s responsibility for workplace safety.
The 60 Minutes report illustrates the difficulty that OHS inspectors face when visiting workplaces. Can an inspector be expected to identify ALL the hazards present in a workplace? This is a constant problem for OHS regulators, employers and sadly, the Courts.
The accusation in the 60 Minutes report is that inspectors had no information or training on the explosive hazards of dust. Training is not the solution for everything and an inspector’s state of knowledge should have identified dust as a potential hazard. Even if the hazard was identified in terms of an inhalation risk, or housekeeping, the explosive risk would be reduced if housekeeping was applied properly.
OSHA clearly stated the responsibility of workplace safety being on the employers. The missing element of the entire 60 Minutes report is that the site operators and employers who have experienced dust explosions were not interviewed.
