3.         HAZARDS IDENTIFICATION

 

EMERGENCY OVERVIEW

 

Product is a clear liquid with a pungent, sour, penetrating odor.  Liquid may cause severe irritation and chemical burns of the eyes, skin, mucous membranes, and respiratory tract.  Development of acid burns may take up to 12 hours after exposure.  Wear appropriate personal protective equipment.  Keep individuals not involved in the clean-up out of the area.  Prevent spread of release by diking with earth, sand, or other non-reactive materials.  Prevent entry into storm or sanitary sewers, ground water, or soil.  Absorb released material with an absorbent suitable for acidic materials or pump into appropriate containers for disposal.  After clean up, slowly neutralize residual materials with a weakly basic media, preferably ground or powdered limestone.  All materials collected during clean-up operations may be contaminated and should be treated as hazardous unless specific testing, including TCLP, shows the collected material to be non-hazardous.

 

3.         HAZARDS IDENTIFICATION – Continued

 

POTENTIAL HEALTH EFFECTS

 

Eye:  Corrosive.  Contact may cause severe irritation and chemical burns of the eyes. Acid  burns may not become evident for up to 12 hours after exposure.

 

Skin Contact:  Corrosive.  May cause severe irritation and chemical burns of the skin.  Acid burns                                               may not become evident for up to 12 hours after exposure.

 

Skin Absorption:   Not known to be absorbed through the intact skin.

 

Ingestion: Corrosive.  Harmful or fatal if ingested.  May cause severe irritation and burns of the mouth, throat and digestive tract.

 

Inhalation: Corrosive. May cause severe irritation and chemical burns of the mucous membranes and respiratory tract.

Chronic and

Carcinogenicity:  Prolonged exposure may cause dermatitis.  The product has not been identified as a carcinogen or potential carcinogen.  Pre-existing skin, lung, central nervous system, and kidney conditions may be aggravated by exposure to the components of the product.  Exposure to fluorides at concentrations well above the TLV or PEL may cause a fluorosis.  See Section 11.

 

4.         FIRST AID MEASURES

 

Inhalation:  Remove exposed person to fresh air.  If breathing is difficult, oxygen may be administered. Treat symptomatically. Seek medical attention.

 

Eyes:  Flush with tepid water for at least 20 minutes holding the eyelids wide open.  Seek medical attention immediately .

 

Skin:  Immediately flush with plenty of water and wash thoroughly with mild soap and water.  Remove any contaminated clothing. Discard contaminated clothing properly. Seek medical attention immediately and advise medical personnel of possible fluoride exposure.

 

Ingestion:  SEEK MEDICAL ATTENTION IMMEDIATELY.  Give water to dilute.  Do not induce vomiting unless directed by licensed medical personnel.  Advise medical personnel of possible fluoride  exposure.  Never give anything by mouth to an unconscious individual.

 

5.         FIRE FIGHTING MEASURES

 

Flash Point:     NA                    LEL: NA                    UEL: NA                    Auto Ign. Temp.: NA

 

Product will not ignite.  Material in or near fires should be cooled with a water spray or fog if compatible with fire fighting techniques for the other materials involved in the fire.  A self-contained breathing apparatus operating in the positive pressure mode and full fire fighting gear should be worn for combating fires.  Water used to fight fires should be contained.  See Section 12.

 

6.         ACCIDENTAL RELEASE MEASURES

 

Prevent spread of release by diking with earth, sand, or other non-reactive materials.  Absorb releases with an absorbent suitable for acidic materials or pump into appropriate containers for disposal.  After initial clean up, slowly neutralize the release area with a weakly basic media, preferably ground or powdered limestone.    Appropriate personal protective equipment cited in Section 8 should be worn during all clean-up operations.  All materials collected during clean-up operations may be contaminated and should be treated as hazardous unless specific testing, including TCLP, shows the collected material to be non-hazardous.  Releases may be reportable to local, state, and/or federal authorities.  See Sections 12 & 15.

 

7.         HANDLING AND STORAGE

 

Do not store in metal containers or with or near incompatible materials cited in Section 10.  Store in tightly closed containers out of contact with the elements.  Appropriate personal protective equipment cited in Section 8 should be worn during handling.  Good housekeeping and engineering practices should be employed to prevent spills of the product in the workplace.  Any spills should be cleaned up as soon as possible to minimize the possibility of contact.  See Section 6.  Wash hands and face thoroughly before eating, drinking or smoking.

 

8.         EXPOSURE CONTROL – PERSONAL PROTECTION

 

Engineering Controls:  Local exhaust ventilation should be provided to maintain exposures below the limits cited in Section 2.  The need for local exhaust ventilation should be evaluated by a professional industrial hygienist.  Local exhaust ventilation systems should be designed by a professional engineer.  Eye wash and shower stations

should be available where acid is being handled.

 

Respiratory Protection: If exposures may exceed the limits cited in Section 2, use, as a minimum, a NIOSH approved 1/2 face-piece respirator with cartridges approved for acid gases, hydrogen fluoride.  If exposures exceeds 20ppm, consult your respiratory protection equipment supplier or a professional industrial hygienist for selection of the proper equipment.  The evaluation of the need for respiratory protection should be made by a professional industrial hygienist.

 

Eye/Face Protection:  Chemical protective goggles and full-face shield are recommended where there is the possibility of eye contact with the product.  Contact lenses should not be worn.

 

Skin:  Acid proof gloves, headgear, clothing and protective should be worn to prevent contact.

 

General:  Eye wash and emergency shower facilities should be available in handling areas.

Stability & Polymerization:  Product is stable.  Hazardous polymerization will not occur.

 

Incompatibility (Conditions to Avoid):  Do not store in metal or glass containers, with or near strong acids or alkalies, explosives, toxicants, readily oxidizable materials, alkalie metals, reducing agents, stoneware, or concrete.  Fluorosilicic acid can react with many metals to liberate hydrogen gas which is highly flammable.  May react with strong mineral acids to liberate hydrogen fluoride or hydrofluoric acid which are highly toxic and corrosive.

 

Hazardous Decomposition Products:  Extreme temperatures such as a fire cause formation of highly toxic and corrosive fumes of fluorides such as SiF4 and HF. Hydrogen gas may be formed at temperatures above 227oF
