FIRE FIGHTING MEASURES
FIRE Not combustible, but substance is a strong oxidizer and its
heat of reaction with reducing agents or combustibles may
cause ignition. Can react with metals to release flammable
hydrogen gas.
EXPLOSION Reacts explosively with combustible organic or readily
oxidizable materials such as: alcohols, turpentine, charcoal,
organic refuse, metal powder, hydrogen sulfide, etc. Reacts
with most metals to release hydrogen gas which can form
explosive mixtures with air.
FIRE EXTINGUISHING MEDIA Water spray may be used to keep fire exposed containers
cool. Do not get water inside container.
SPECIAL INFORMATION Increases the flammability of combustible, organic and readily
oxidizable materials. 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. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area.
Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Neutralize with
alkaline material (soda ash, lime), then absorb with an inert material (e.g. vermiculite, dry sand, earth), and place in a chemical
waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! US Regulations (CERCLA)
require reporting spills and releases to soil, water and air in excess of reportable quantities.
HANDLING AND STORAGE
Store in a cool, dry, ventilated storage area with acid resistant floors and good drainage. Protect from physical damage. Keep
out of direct sunlight and away from heat, water, and incompatible materials. Do not wash out container and use it for other
purposes. When diluting, the acid should always be added slowly to water and in small amounts. Never use hot water and
never add water to the acid. Water added to acid can cause uncontrolled boiling and splashing. 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):
2 ppm (TWA), 4 ppm (STEL)
ACGIH Threshold Limit Value (TLV):
2 ppm (TWA); 4 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, wear a supplied air, full face
piece respirator, air-lined hood, or full face piece
self-contained breathing apparatus. Nitric acid is an oxidizer
and should not come in contact with cartridges and canisters
that contain oxidizable materials, such as activated charcoal.
Canister-type respirators using sorbents are ineffective.
SKIN PROTECTION Wear impervious protective clothing, including boots, gloves,
lab coat, apron or coveralls, as appropriate, to prevent skin
contact.
EYE PROTECTION Use chemical safety goggles and/or a full face shield where
splashing is possible. Maintain eye wash fountain and
quick-drench facilities in work area.
