FIRE FIGHTING MEASURES
FIRE Auto-ignition temperature
Flammable limits in air % by volume
651C (1204F)
lel: 16; uel: 25
EXPLOSION Flammable vapors may accumulate in confined spaces.
FIRE EXTINGUISHING MEDIA Use any means suitable for extinguishing surrounding fire.
Use water spray to blanket fire, cool fire exposed containers,
and to flush non-ignited spills or vapors away from fire.
SPECIAL INFORMATION In the event of a fire, wear full protective clothing and
NIOSH-approved self-contained breathing apparatus with full
face piece operated in the pressure demand or other positive
pressure mode.
MEASURES IN CASE OF SPILLAGE
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Wear appropriate personal
protective equipment as specified in Section 8. Contain and recover liquid when possible. Do not flush caustic residues to the
sewer. Residues from spills can be diluted with water, neutralized with dilute acid such as acetic, hydrochloric or sulfuric.
Absorb neutralized caustic residue on clay, vermiculite or other inert substance and package in a suitable container for
disposal.
HANDLING AND STORAGE
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Separate from
incompatibilities. Store below 25C. Protect from direct sunlight. Containers of this material may be hazardous when empty
since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.
EXPOSURE CONTROLS / INDIVIDUAL PROTECTION
AIRBORNE EXPOSURE LIMITS OSHA Permissible Exposure Limit (PEL):
50 ppm (NH
3
)
ACGIH Threshold Limit Value (TLV):
25 ppm (NH
3
) (TWA) 35 ppm (STEL)
VENTILATION SYSTEM A system of local and/or general exhaust is recommended to
keep employee exposures below the Airborne Exposure
Limits. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its
source, preventing dispersion of it into the general work area.
Please refer to the ACGIH document, Industrial Ventilation, A
Manual of Recommended Practices, most recent edition, for
details.
PERSONAL RESPIRATORS (NIOSH APPROVED) If the exposure limit is exceeded and engineering controls are
not feasible, a full face piece respirator with an
ammonia/methylamine cartridge may be worn up to 50 times
the exposure limit or the maximum use concentration
specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. For emergencies or instances
where the exposure levels are not known, use a full face
piece positive-pressure, air-supplied respirator. WARNING:
Air purifying respirators do not protect workers in
oxygen-deficient atmospheres.
SKIN PROTECTION Wear impervious protective clothing, including boots, gloves,
lab coat, apron or coveralls, as appropriate, to prevent skin
contact. Neoprene and nitrile rubber are recommended
materials. Polyvinyl alcohol is not recommended.
EYE PROTECTION Use chemical safety goggles and/or full face shield where
dusting or splashing of solutions is possible. Maintain eye
wash fountain and quick-drench facilities in work area.
