SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
RESPIRATORY PROTECTION: WEAR AN APPROVED NIOSH DUST RESPIRATOR WHENEVER DUST
CONCENTRATIONS IN THE WORK AREA ARE ABOVE ACGIH TLV/OSHA PELS
GRAIN DUST (WHEAT, OAT AND BARLEY)
OSHA PEL ACGIH TLV
10 MG/M3 4MG/M3*
OTHER GRAINS
OSHA PEL ACGIH TLV
15 MG/M3 (TOTAL) 10 MG/M3*
5 MG/M3 (RESPIRABLE)
* THIS TLV APPLIES TO NUISANCE PARTICULATES.
THE GRAIN INDUSTRY BELIEVES THERE IS CURRENTLY INADEQUATE DATA TO SUPPORT THIS TLV.
VENTILATION: LOCAL EXHAUST: IF NEEDED
MECHANICAL (GENERAL): IF NEEDED
ENSURE THAT DUST HANDLING SYSTEMS (SUCH AS EXHAUST DUCTS, DUST COLLECTORS, VESSELS,
AND PROCESSING EQUIPMENT) ARE DESIGNED IN A MANNER TO PREVENT THE ESCAPE OF DUST INTO
THE WORK AREAS. USE ONLY APPROPRIATELY CLASSIFIED ELECTRICAL EQUIPMENT AND POWERED
INDUSTRIAL TRUCKS.
PROTECTIVE GLOVES: N/A
EYE PROTECTION: SAFETY GLASSES / GOGGLES SUGGESTED IN DUSTY CONDITIONS
WORK/ HYGIENIC PRACTICES: GOOD PERSONAL HYGIENE PRACTICES SHOULD BE FOLLOWED.
AVOID EXCESSIVE DUST ACCUMULATION AND CONTROL IGNITION SOURCES. WHERE APPROPRIATE,
EMPLOY GROUNDING, VENTING, AND EXPLOSION RELIEF PROVISIONS IN ACCORDANCE WITH
ACCEPTED ENGINEERING PRACTICES IN PROCESSES CAPABLE OF GENERATING DUST AND/OR STATIC
ELECTRICITY
SECTION 9: PHYSICAL AND CHEMICAL PROPERTIES
FLASH POINT (METHOD): N/A
FLAMMABLE LIMITS: LEL: UNKNOWN UEL: UNKNOWN
AUTOIGNITION TEMPERATURE: UNKNOWN
APPEARANCE:
NATURAL GRAIN COLOR – WHOLE GRAIN
GRAIN DUST - LIGHT, GRAYISH OR BROWN POWDER
UPPER/LOWER FLAMMABILITY OR EXPLOSIVE LIMITS: WHEN DISPERSED INTO THE AIR IN
SUFFICIENT CONCENTRATIONS GRAIN DUST CAN EXPLODE IN THE PRESENCE OF AN IGNITION
SOURCE. DO NOT ALLOW DUST TO BECOME DISPERSED INTO THE AIR, EVEN BY THE EXTINGUISHING
AGENT. MINIMUM EXPLOSIVE CONCENTRATION IS 55 G/M3. HOWEVER, MOISTURE CONTENT,
PARTICLE SIZE, CALORIC PROPERTIES, AND SPECIFIC INGREDIENTS ALSO AFFECT THE
EXPLOSIVENESS OF GRAIN DUST.
THE FLASH POINT AND FLAMMABLE LIMITS ARE ACCURATE BECAUSE GRAIN DUST HAS NO FLASH
POINT, LEL, OR UEL DUE TO ITS PROPERTIES. THE FIREFIGHTING MEASURES LISTED ARE IN ACCORD
WITH OTHER SIMILAR SDS.
