IDENTIFICATION OF HAZARDS
Causes severe irritation and burns. Harmful if swallowed. Avoid breathing vapor or dust. Use with adequate ventilation. Avoid
contact with eyes, skin, and clothes. Wash thoroughly after handling. Keep container closed.
FIRST AID
CHRONIC EXPOSURE Long-term exposure to concentrated vapors may cause
erosion of teeth and lung damage. Long-term exposures
seldom occur due to the corrosive properties of the acid.
AGGRAVATION OF PRE-EXISTING CONDITIONS Persons with pre-existing skin disorders, eye disease, or
cardiopulmonary diseases may be more susceptible to the
effects of this substance.
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 facepiece 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.
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 sawdust.
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.
