4. FIRST-AID MEASURES

 

INHALATION:

If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate medical attention.

 

SKIN CONTACT:

Wash skin with soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get immediate medical attention. Thoroughly clean and dry contaminated clothing and shoes before reuse. Destroy contaminated shoes.

 

EYE CONTACT :

Immediately flush eyes with plenty of water for at least 15minutes. Then get immediate medical attention.

 

INGESTION:

If swallowed , drink plenty of water ,do NOT induce vomiting.Get immediate medical attention. NOTE TO PHYSICIAN: For inhalation, consider oxygen. Avoid gastric lavage or emesis .

 

 

5. FIRE-FIGHTING MEASURES

 

SUITABLE EXTINGUISHING MEDIA:

Regular dry chemical, carbon diox ide, water , regular foam

Large fires: Use regular foam or flood with fine water spray. FIRE AND EXPLOSION HAZARDS: Negligible fire hazard.

FIRE FIGHTING:

Move container from fire area if it can be done without risk.

Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks.

 

 

6. ACCIDENTAL RELEASE MEASURES

 

-PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT & EMERGENCY PROCEDURES:

 

-ENVIRONMENT PRECAUTION:

SOIL RELEASE: Dig holding area such as lagoon, pond or pit for containment. Cover with plast ic sheet or tarpaulin to minimize spreading and protect from contact with water.

WATER RELEASE:

Neutralize.

 

-METHODS & MATERIALS FOR CONTAINMENT & CLEAN ING UP

Do not touch spilled material. Stop leak if possible without personal risk.

 

Small spills: Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal. Small dry spills: Move containers away from spill to a safe area.

Large spills: Dike for later disposal. Keep unnecessary people away, isolate hazard area and deny entry.

 

 

7. HANDLING AND STORAGE

 

-PRECAUT IONS FOR SAFE HANDLING:

Use smallest possible amounts in designated areas with adequate ventilation. Keep containers closed w hen not in use. Empty containers may contain hazardous residues. Transfer solids using tools or equipment, which are corrosion -resistant. Cautiously, transfer into sturdy containers made of compatible materials . Never return contaminated material to its original container .Considerable heat is generated when diluted with water. Proper handling procedures must be followed to prevent vigorous boiling, splattering or violent erupt ion of the diluted solution. Never add water to caustic. ALWAYS ADD CAUSTIC TO WATER and provide agitation. When mixing with water, stir small amounts in slowly. Use cold water to prevent excessive heat generation. In general, keep solid sodium hydroxide away from water .

 

-PRECAUTIONS FOR SAFE STORAGE (including any incompatibilities):

Store in a cool, dry, well-ventilated area. This material absorbs water. Keep containers tightly closed when not in use and when empty. Protect from damage. Store away from incompatable materials such as strong acids, nitroaromat ic, nitroparaffinnic or organohalogen compounds. Use corrosion-resistant structural materials and lighting and ventilation systems in the storage area. Containers made of nickel alloys are preferred. Steel containers are acceptable iftemperatures are not elevated. Nickel is the preferred metal from

handling this product. Plastics or plastic-lined steel, or FRP tanks of derakane vinyl ester resin may be suitable . If outdoor storage of pearl caust ic is unavailable, the pallets should be protected against extremes of weather.

8. EXPOSURE CONTROLS AND PERSONAL PROTECTION

 

-CONTROL PARAMETERS:

OCCUPATIONAL EXPOSURE LIMIT or BIOLOGICAL LIMIT VALUE:

2 mg/m3 MINISTRY OF LABOUR, THAILAND TLV-C

2 mg/m3 OSHA TWA

2 mg/ m3 OSHA ceiling (vacated by 58 FR 35338, June 30, 1993)

2 mg/ m3 ACGIH ceiling

2 mg/m3 NIOSH recommended ceiling

-APPROPRIATE ENGINEERING CONTROLS:

 

Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of t he contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. The most effective measures are the total enclosure of processes and the mechanization of handling procedures to prevent all personal contact. VENTILATION: Ensure compliancewith applicable exposure limits.

 

PERSONAL PROTECTIVE EQUIPMENT

Maintain eye wash fountain and quick-drench facilities in work area. Detailed requirements for personal protective equipment should be established on a site-specific basis.

 

EYE PROTECTION:

Wear full face-shield and chemical safety goggles when there is potential for contact.

SKIN PROTECTION:

Wear appropriate personal protective clothing to prevent skin contact. Chemical protective clothing composed of natural rubber, neoprene, nitrile, or styrene/butadi ene (SBR)-coated fabric is highly recommended, having break through times greater than one hour. Butyl rubber, polyethylene, chlorinated polyurethane, or polyvinyl alcohol may be used but data suggests breakthrough times of approximately an hour or more.

 

RESPIRATORY PROTECTION:

 

Up To 10 mg/m3 : Supplied Air Respirator (SAR) operated in a continuous-flow mode, eye protection needed; or full-facepiece respirator with high-efficiency particulate filter(s); or powered air-purifying respirator with dust and mist filter(s) , eye protection needed; or full-facepiece Self-Contained Breathing Apparatus (SCBA); or full• facepiece SAR.

Emergency or Planned Entry into Unknown Concentrations or IDLH Conditions: Positive pressure, full• facepiece SAR; or positive pressure, full-facepiece SAR with an auxiliary positive pressure SAR

11. TOXICOLOGICAL INFORMATION (CONTINUED)

 

Carcinogenic classification: NTP : Not Established.

IARC Monographs : Not Established . OSHA Regulated : Not Established.

 

Other information: Since burns of the skin or membrane by contact is based on the dissolution action to the protein of alkali as compared with acid, generally, wound is moist and an ulcer tends to advance deeply, so it is more critical than the burn by acid.

Aquatic organism : LDso : 10-100 mg/1 96 h. High toxic to fish and plankton due to pH changing. But not result in a lack of oxygen in ecological system .

 

 

13. DISPOSAL CONSIDERATIONS

 

Review federal, state and local government requirements prior to disposal. Do not dispose of waste with normal garbage, or to sewer systems. Whatever cannot be saved for recovery or recycling, including containers, should be managed in an appropriate and approved waste disposal facility. Processing, use or contamination of this product may change the waste management options
