4, FIRST AID MEASURES
INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration it'notbreathing. Ifbreathing is difficult, oxygen should be administered by qualified personnel. If respiration or puls~has stopped, have a trained person administer Basic Life Support (Cardio-Pulmonary Resuscitationi AutomaticE",1emal Defibrillator) and CALL FOR EMERGENCY SERVICES IMMEDIA TEL y .
SKIN CONTACf: Immediately flush contaminated are~ with water. Remove contaminated clothing. jewelry.and shoes immediately. W~h c~ntaminated areas with soap and water. Thoroughly clean and dry contmninatedclothing and shoes before reuse. Discard footwear which cannot be decontaminated. GET MEDICALA TTEN11 ON IMMEDIA TEL Y.
EYE CONTACT: Immediately flush eyes with a directed stream ofwater for at least 15 minutes. forciblvholding eyclids apart to ensure comple~ irrigation of all eye and lid tissues. Washing eyes within scvcral.seconds is essential to achieve maximum effectiveness. GET MEDICAL A TfENTION IMMEDIA TEL \..
ING ESTION : Never give anything by mouth to an unconscious or con,,'Ulsive person. If swallowed, do notinduce vomiting. Give large amounts ofwater. If vomiting occurs spontaneously. keep airway clear. Give morewater when vomiting stops. GET MEDICAL A TTENTION IMMEDIA TEL Y.

NOTE TO PHYSICIAN: The absence of visible signs or symptoms of bums does NOT reliably exclude thepresence of actual tissue damage.
EXTINGUISHING MEDIA: Do not use water. Use extinguishing agents appropriate for suITounding fire.
FIRE FIGHTING: Move container from fire area if it can be done without risk.

6. ACCIDENTAL RELEASE MEASURES
OC(...UPATIONAL RELEASE:Shovel dry material into suitable container. Keep out ofwater supplies and sewers. This material is alkaline andmay raise the pH of surface waters with low buffering capacity .Relea.l;es should be reported, if required, toappropriate agencies. Notify Local Emergency Planning Committee and State Emergency ResponseCommission for release greater than or equal to RQ (U.S. SARA Section 304). If release occurs in the U.S. aJldis reportable under CERCLA Section 103, notify the National Respol1Se Center at (800)424-8802 (USA) or
(202)426-2675 (USA).
7. HANl)I..ING AND Sl'ORAGE
STOR.\GE: Store and handle in accordance with all current regulations and standards. Keep container tightl~'closed and properly labeled. Do not store in aluminum container or use aluminum fittings or transfer lines, asflammable hydrogen gas may be generated. Keep separated from incompatible substances.
HANDLING: Avoid breathitlg dust. Do not get in eyes, on skin, or on clothing. Wash thoroughly afterhandling. When mixing, slowly add to water to minimize heat generation and spattering.
VENTILATION: Provide local exhaust ventilation where dust or mist may be generated. Ensure compliancewith applicable exposure limits.
EYE PROTEcrION: Wear chemical resistant safety goggles if eye con~--t is likely. When wet mixing. wearsplash resistant safety goggles with a faceshield. Provide an emergency eye wash fountain and quick drench

shower in the immediate work area.
CLOTHING: Wear protective clothing to minimize skin contact. When potential for contact with wet materialexists, wear Tychem(R) SL or a similar chemical protective suit. When potential for contact with dry materialexists, wear disposable coveralls such as Tyvek(R).
GLOVES: Wear suitable gloves. Discard contaminated leather goods. When wet mixing. wear chemicalresistant gloves such as butyl rubber, natural rubber, neoprene or nitrile.
RESPIRA TOR: A NIOSH approved respirator with N95 (dust. fume, mist) filters may be peffilissible undercertain circumstances where airbonle concentrations are expected to exceed exposure limit~ or when symptomshave been observed that are indicative of overex-posure.A half facepiece air-purifying respirator may be used in concentrations up to lOX the acceptable exposure leveland a fidl facepiece air-purifying respirator may be used in concentrations up to 50X the acceptable exposl.lfelevel.Supplied air should be used when the level is expected to be above 50X the acceptable level, or when there is apotential for uncontrolled release.A respiratory protection program that meets 29 CFR 1910.134 must be followed whenever workplaceconditions warrant use of a respirator.

CAUSTIC SODA ANHYDROUS (ALL GRADES):TOXICITY DATA: Sodium Hydroxide: 1350 mg/kg Dermal-Rabbit LD50. 220 mg/kg (50~/o solution) Oral-Rat LD50. As a solid, this material interacts with moist tissue to cause damage. When in solution. this materialwill affect all tissues with which it comes in contact. The severity of the tissue damage is a function of itsconcentration. the length of tissue contact time, and local tissue conditions. After exposure there may be a timedelay before irritation and other effects occW'. This material is a strong irritant and is corrosive to the skin. eyes,and mucous membranes. This material may cause severe burns and permanent damage to any tissue with whichit comes into contact, Inhalation will cause severe irritation, possible bums with pulmonary edema, which maylead to pneumonitis. Skin contact with this material may cause severe irritation and corrosion oftissu~. Eyecontact can cause severe irritation, corrosion with possible corneal damage and blindness. In general. chroniceffects are due to long-term irritation. This material may cause dermatitis on the skin. or recW'rent cornealulceration and visual disturbances. In rare cases reports have noted long-term inhalation causes bronchialiJillanlmatory reaction or obstructive airway dysfunction.
