RATE CLASSIFICATION: Flame spread rate classifications are established by the model building codes for various types of
construction.
The classifications commonly used are listed below:
Model Code Flame Spread Rate
(1) Boca Class I 0-25
Boca Class II 26-75
Boca Class III 76-200
Boca Class IV over 200
(2) SBCCI (Classifications are not listed. Flame spread rate values are specified for specific areas of buildings.)
(3) ICBO Class I 0-25
ICBO Class II 26-75
ICBO Class III 76-225
FLAME SPREAD – Class III – under 200 – in accordance with ASTM E-84-91A and ANSI / AHA A 135.5
FLASH POINT: Not applicable.
EXPLOSIVE LIMITS: Sawing, sanding or machining wood products can produce wood dust as a by-product. Wood dust is a strong to
severe explosion hazard if a dust "cloud" contacts an ignition source. 212°F (100°C) has been suggested as the upper temperature
limit for continuous exposure for wood without risk of ignition (wood dust may require a still lower temperature). An airborne
concentration of 40 grams of dust per cubic meter of air is often used as the lowest explosion limit (LEL) for wood dust.
HAZARDOUS COMBUSTION PRODUCTS: Thermal-oxidative degradation, or burning, of wood can produce irritating and potentially
toxic fumes and gases including carbon monoxide, aldehydes and organic acids.
AUTOIGNITION TEMPERATURE: 400°-500° F (204°-260°C)
FIRE EXTINGUISHING MEDIA: Water. Partially burned dust is especially hazardous if dispersed into the air. Remove burned or wet
dust to open area after fire is extinguished.
SECTION 5. ACCIDENTAL RELEASE MEASURES
Not applicable for product in purchased form. Sweep or vacuum dust for recovery or disposal. Wood dust clean-up and disposal
activities should be accomplished in a manner to minimize creation of airborne dust.
SECTION 6. HANDLING AND STORAGE
Wood products are combustible and, therefore, should not be subjected to temperatures exceeding the autoignition temperature.
Water spray may be used to wet down wood dust generated by sawing, sanding or machining to reduce the likelihood of ignition or
dispersion of dust into the air. See other sections of this MSDS for information on handling.
SECTION 7. EXPOSURE CONTROLS/ PERSONAL PROTECTION
ENGINEERING CONTROLS: Due to the explosive potential of wood dust when suspended in air, precautions should be taken during
sanding, sawing or machining of wood products to prevent sparks or other ignition sources in ventilation equipment. Use of totally
enclosed motors is recommended. Provide local exhaust as necessary to meet OSHA requirements.
