Guidance document focuses on combustible dust hazards

The US-American Occupational Safety & Health Administration (OSHA) published a
new document titled "Hazard Communication Guidance for Combustible Dusts" that
helps chemical manufacturers and importers recognize the potential for dust
explosions, identify appropriate protective measures, and fulfill the
requirements for disseminating this information on material safety data sheets
and labels.

Combustible dusts are fine particles that present an explosion hazard when
suspended in air under certain conditions. A dust explosion can cause
catastrophic loss of life, injuries, and destruction of buildings. When these
incidents or accidents occur, workers and managers were often unaware of the
potential for dust explosions, or failed to recognize the serious nature of
dust explosion hazards. Frehsly reviewed Material Safety Data Sheets (MSDS) of
140 known substances that produce combustible dusts and found poor or
inadequate transmittal of information regarding potential dust hazards; 41% of
the MSDSs reviewed did not warn users about potential explosion hazards. Of the
remaining 59% of MSDSs sampled, most of the information was either not stated
in a place or manner clearly recognized by workers, or was not specific to
hazards related to combustible dusts.
