Although this material is not combustible, it can be hazardous if present in a fire area. It can melt and flow when heated (m.p. 318C). The hot or molten material can react violently with water (splattering) and can cause ignition of combustible materials. It can also react with certain metals, such as aluminum, to generate flammable hydrogen gas. (Also see Section 5).
Firefighters should wear self-contained breathing apparatus and full protective gear when fighting fires involving this material.
SECTION 5. REACTIVITY DATA
This material is staole unaer normal conditions of storage and handling. It does not undergo hazardous polymerization nor does it evolve any hazardous decomposition products. It slowly absorbs moisture from the air and reacts with carbon dioxide from the air to form sodium carbonate. Sodium hydroxide reacts violently with water, strong acids and with many organic chemicals, especially with nitrocarbons and chlorocarbons. It will react with trichloroethylene to form spontaneously flammable dichloroacetylene. Considerable heat is generated when it dissolves in water. Avoid contact with leather and wool. Contact with aluminum, tin, zinc, and alloys that contain these metals causes the formation of hydrogen gas (flammable).

SECTION 6. HEALTH HAZARD INFORMATION
TLV (Ceiling limit) 2mg/taJ
Sodium nyaroxide is a strong alkali and is dangerous wnen improperly nanalea. it can oe destructive to ail
human tissue it contacts, producing severe bums. Eye contact causes severe, permanent injury. Skin contact
causes irritation and, if not removed immediately, severe bums with scarring. The effects of inhalation of
the dust or mist vary from mild irritation to destructive bums. Pneumonitis may occur. Ingestion causes
severe bums of the mouth, throat and stomach and may be fatal.
FIRST AID: EYE CONTACT: Wash eyes immediately with plenty of running water for no less than IS minutes,
including under the eyelids and all surfaces. Speed in rinsing out the eyes with wateT after contact is
extremely important if permanent injury is to be avoided. Get medical attention promptly. SKIN CONTACT: Wash
contaminated area promptly with large quantities of water. Remove contaminated clothing while washing. Pro
long washing in serious cases until medical help arrives - even for an hour or longer. Physician should see
all cases other than minor exposures to small areas of the skin. INHALATION: Remove from exposure to mist
or dust and get prompt medical help. INGESTION: Immediately give person large quantities of water or milk
to drink (never give anything by mouth to an unconscious person). DO NOT induce vomiting. Obtain medical
assistance immediately.
SECTION 7. SPILL. LEAK AND DISPOSAL PROCEDURES
Clean-up personnel should wear protective equipment to prevent skin and eye contact. Promptly shovel up spilled solid sodium hydroxide into suitable containers for reclaim. Avoid dust generation! Clean-uD soills oromotly as moisture absorption from air mpy make clean-up difficult. Flusn contaminated surfaces with water and neutralize with dilute acid, preferably acetic acid, to remove final traces. Finally, rinse with water.
DISPOSAL: Waste caustic should never be discharged directly into drains, sewers or surface waters. Dilute well with water and carefully neutralize with acid. Follow all applicable Federal, State and local regulations.
EPA HAZARDOUS WASTE NUMBER: D002, corrosive (solns c pH > 12.5 - 40CFR261.22). REPORTABLE SPILL QUANTITY: 1000 lbs (40CFR117).
SECTION 8. SPECIAL PROTECTION INFORMATION
Provide adequate general ana/or iocai exnaust ventilation to meet iLV requirements, especially wnere ousting or misting conditions can exist. Use a NIOSH approved respirator for dust/mist where needed. Use chemical safety goggles, A plastic face shield in addition to safety goggles is also desirable where misting/splashing may occur. Use rubber gloves, rubber apron or protective suit, and rubber boots where needed to prevent contact with sodium hydroxide, especially when preparing solutions. Eye wash stations and safety showers must be immediately available.
This is a special hazard to contact lenses wearers; soft lenses may absorb and all lenses concentrate irritants. Contact between caustic and contact lenses will severely hamper contact lens removal due to the slippery nature of this caustic.
SECTION 9. SPECIAL PRECAUTIONS AND COMMENTS
Store in well-sealed containers in a dry location. Protect containers from physical damage. Avoid handling conditions that may lead to spills or leaks or the formation of mist or dust. Wherever this material is stored, unloaded, handled or used, abundant water (preferably running water) should be available for emergency use. Drains servicing areas where this material is stored or used should have retention basins for pH adjustment and dilution of spills and flushings before discharge. Workers handling this material should be trained in proper handling and emergency procedures. DOT HAZARD CLASSIFICATION: Corrosive Material
