**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns. Heating may cause an explosion. Contact with
combustible material may cause fire.Corrosive.Hygroscopic.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
Causes severe respiratory tract irritation with possible burns.
Chronic:
Prolonged or repeated skin contact may cause sensitization
dermatitis and possible destruction and/or ulceration.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
Destroy contaminated shoes. In case of contact, immediately flush
skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Get medical aid immediately. Wash
clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Strong oxidizer. Contact with combustible materials
may cause a fire. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Containers may explode in
the heat of a fire. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. Some
oxidizers may react explosively with hydrocarbons(fuel). Contact
with metals may evolve flammable hydrogen gas. May decompose
explosively when heated or involved in a fire. Fight fire from
protected location or maximum possible distance.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use flooding quantities of water.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Neutralize spill with sodium bicarbonate. Remove
all sources of ignition. Absorb spill using an absorbent,
non-combustible material such as earth, sand, or vermiculite. Do not
use combustible materials such as saw dust. Flush spill area with
water. Wet area to prevent drying out. Provide ventilation. Keep
combustibles (wood, paper, oil, etc.,) away from spilled material.
Keep unnecessary and unprotected personnel away. Use only
non-sparking tools and equipment.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use spark-proof tools and explosion proof
equipment. Avoid contact with clothing and other combustible
materials. Do not get on skin or in eyes. Do not ingest or inhale.
Use only with adequate ventilation. Do not allow perchloric acid to
come into contact with strong dehydrating agents (concentrated
sulfuric acid, anhydrous phosphorous pentoxide, etc.). Keep the
quantities of perchloric acid handled at the bare minimum for safety.
Perchloric acid should be handled in a masonry building with concrete
or tile floors. Handling acid on wooden floors is dangerous,
especially after the acid has dried. The wooden floor will then
become sensitive to ignition by friction. Perchloric acid mist and
vapor can condense in ventilation systems to form metallic
perchlorates, which can be explosive. Inform laundry personnel of
contaminant's hazards.
Storage:
Do not store near combustible materials. Store in a tightly closed
container. Do NOT freeze. Store in a cool, dry area away from
incompatible substances. Avoid storage on wood floors. Perchloric
acid should be stored segregated from all other chemicals & inside
secondary containment (such as pyrex baking dish). It must not be
stored near organic acids, near bases, or near other organic or
flammable material. Shelves and floor material should be
non-combustible and acid-resistant.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Any procedure involving
heating of perchloric acid must be conducted in a perchloric acid
fume hood, with the sash down. No organic materials should be stored
in the perchloric acid hood.
Personal Protective Equipment
Eyes:
Wear chemical goggles and face shield. Use chemical
splash and impact-rated goggles.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
