Handling Procedures
Do not handle material near food, feed or drinking water.
Avoid high concentrations of dust in air and accumulation of dust on equipment. An airborne dust of this
material can create a dust explosion. When handling and processing this material local exhaust ventilation
may be required to control dust and reduce exposure to vapors. To prevent dust explosions employ bonding
and grounding for operations capable of generating static electricity. Protect all equipment from explosions by
following the guidelines in NFPA-68 and NFPA-69. For electrical equipment follow local codes and electrical
classification NFPA-70 (the National Electrical Code), class II, division 2, group G.
Other
Completely empty bag into application equipment. Dispose empty bag in a sanitary landfill or by incineration
as allowed by state and local authorities. Avoid inhalation of smoke if incinerated.

Respiratory Protection
A respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2 requirements or equivalent must
be followed whenever workplace conditions warrant a respirator's use. None required if airborne
concentrations are maintained below the exposure limit listed in 'Exposure Limit Information'.
Up to 1000 ppm organic vapor: Wear a properly fitted NIOSH approved (or equivalent) full-face piece, air-
purifying respirator, OR full face piece, airline respirator in the pressure demand mode.
Above 1000 ppm organic vapor or Unknown: Wear a properly fitted NIOSH approved (or equivalent) self-
contained breathing apparatus in the pressure demand mode, OR full-face piece, airline respirator in the
pressure demand mode with emergency escape provision.
Air-purifying respirators should be equipped with NIOSH approved (or equivalent) organic vapor cartridges
and R100 or P100 filters.
Eye Protection
Use chemical splash goggles (ANSI Z87.1 or approved equivalent). Eye protection worn must be compatible
with respiratory protection system employed.
Hand Protection
Chemical-resistant gloves should be worn whenever this material is handled. The glove(s) listed below may
provide protection against permeation: Polyvinyl chloride-coated glove or other chemical-resistant rubber-
coated glove. Gloves should be removed and replaced immediately if there is any indication of degradation or
chemical breakthrough. Rinse and remove gloves immediately after use. Wash hands with soap and water.
Other Protection
Use chemically resistant apron or other impervious clothing to avoid prolonged or repeated skin contact.
Engineering Controls (Ventilation)
Use local exhaust ventilation with a minimum capture velocity of 150 ft/min. (0.75 m/sec.) at the point of dust
or mist evolution. Refer to the current edition of Industrial Ventilation: A Manual of Recommended Practice
published by the American Conference of Governmental Industrial Hygienists for information on the design,
installation, use, and maintenance of exhaust systems.
Other Protective Equipment
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
