SDS

Self-contained breathing apparatus and full protective clothing must be worn in case of fire.
Special protective equipment
and precautions for firefighters
In case of fire and/or explosion do not breathe fumes. Move containers from fire area if you can do
so without risk.
Fire fighting
equipment/instructions
To avoid dust clouds, responders should use the extinguisher from as far away as possible and
apply the extinguishing agent as gently as possible. The main considerations with hose stream
operation are to avoid creating combustible dust clouds or introducing more air. In particular, the
use of solid streams and direct dust pile hits can disperse dust into the air creating a potential flash
fire hazard. The best way to apply water is in a medium to wide-pattern, as gently as possible.
Responders should use a low nozzle pressure and loft the stream onto the burning material from
as far away as the stream will reach. The use of wide-pattern (or "fog") streams at pressures
typically used.
Specific methods
May form combustible dust concentrations in air.
General fire hazards
6. Accidental release measures
Use only non-sparking tools. Dust deposits should not be allowed to accumulate on surfaces, as
these may form an explosive mixture if they are released into the atmosphere in sufficient
concentration. Wear appropriate protective equipment and clothing during clean-up. Ensure
adequate ventilation. For personal protection, see section 8 of the SDS.
Personal precautions,
protective equipment and
emergency procedures
Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Take
precautionary measures against static discharge. Use only non-sparking tools. Avoid dispersal of
dust in the air (i.e., clearing dust surfaces with compressed air). Vacuum dust with dust ignition
proof vacuum or wet sweep small wood pieces and dust; place in appropriate container for
disposal. Gather larger pieces by an appropriate method. Reduce airborne dust by use of wet
methods (e.g. water mist) and prevent scattering by moistening with water. For waste disposal, see
section 13 of the SDS.
Methods and materials for
containment and cleaning up
Avoid discharge into drains, water courses or onto the ground.
Environmental precautions
7. Handling and storage
Dust can form an explosive mixture in air. Provide appropriate exhaust ventilation at machinery
and at places where dust can be generated. Minimize dust generation and accumulation. Avoid
significant deposits of material, especially on horizontal surfaces, which may become airborne and
form combustible dust clouds and may contribute to secondary explosions. Routine housekeeping
should be instituted to ensure that dusts do not accumulate on surfaces. If flash fire or explosion
hazard is present, wear flame resistant clothing and face/head protection. Dry powders can build
static electricity charges when subjected to the friction of transfer and mixing operations. Provide
adequate precautions, such as electrical grounding and bonding, or inert atmospheres. Keep away
from heat/sparks/open flames/hot surfaces. - No smoking. Avoid contact with eyes, skin, and
clothing. Avoid prolonged exposure. Wear appropriate personal protective equipment. Use
personal protective equipment as required. Ensure dust collection systems used for conveying
combustible wood dusts are protected with and equipped with fire and explosion prevention and
protection equipment. See NFPA 664 and NFPA 69 for further requirements, information and
guidance.
Precautions for safe handling
Store flat, supported and protected from direct contact with the ground. Store away from
incompatible materials (see Section 10 of the SDS). Store in a cool dry place.
