SYMPTOMS OF OVEREXPOSURE for each potential route of exposure. (Possible Longer Term Effects): N/A,

SIGNS AND SYMPTOMS OF EXPOSURE(Acute effects),

Inhaled Corrosive! Irritating to respiratory tract; inhalation of vapors can cause coughing, choking, inflammation of the nose, throat, and upper respiratory tract, and in severe cases, pulmonary edema, circulatory failure, and death Contact with skin or eyes: Corrosive! Skin contact can cause redness, pain, and severe skin burns unless the hydrochloric acid is washed off immediately. Skin may dry or crack due to astringent nature of material. Repeated skin contact may lead to development of dermatitis. Concentrated solutions cause deep ulcers and discolor skin. Eye contact results in severe irritation and painful burns of the eyes and eyelids. If material is not removed by copious irrigation with water at room temperature, visual Impairment or total loss of vision could result.

Absorbed through skin : May cause deep ulcers and discolor skin. Swallowed Corrosive! Swallowing hydrochloric acid can cause immediate pain and burns of the mouth, throat, esophagus and gastrointestinal tract. May cause nausea, vomiting, and diarrhea. Swallowing may be fatal. Suspected cancer agent : NO This product's ingredients are not found in the lists below. Federal OSHA : NO NTP: NO IARC: NO.

3.FIRST AID: EMERGENCY PROCEDURES:

Eye Contact : Immediately flush eyes with plenty of water for at least 15 min­ utes, lifting lower and upper eyelids oc­ casionally to ensure thorough rinsing; delay can result to permanent injury. Get medical attention immediately. Skin Contact : In case of contact, immedi­ ately flush skin with plenty of water, avoiding hot water or hard scrubbing, for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical atten­ tion immediately. Inhaled : If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is diffi­ cult, give oxygen. Call a physician. Swallowed : Do not induce vomiting! Give large quantities of water or milk if available. Never give anything by mouth to an unconscious person. Get medical attention immediately.

4.FIRE AND EXPLOSION:

Flash Point : N/ A Auto ignition temperature, °F : N/ A Flammable limits in air, volume% : Lower, (LEL): N/A Upper ,(UEL):N/A, Fire extinguishing materials : Water spray : N/ A Carbon dioxide : N/ A other: N/ A Foam: N/A Dry chemical : Special fire fighting procedures : N/ A Unusual fire and explosion hazards : N/ A.

5.SPILL,LEAK,AND DISPOSAL PROCEDURES:

Small Spill: Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste dis­ posal container. If necessary: Neutralize the residue with a dilute solution of sodium carbonate. Large Spill: Corrosive liquid. Poisonous liquid. Stop leak if without risk. Absorb with DRY earth, sand or other non-com­ bustible material. Scoop up and place in a proper waste disposal container. Do not get water inside container. Do not touch spilled material. Use water spray curtain to divert vapor drift. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed Preparing wastes for disposal (container types, neutralization, etc): Whatever cannot be saved for recovery or recy­ cling should be handled as hazardous waste and sent to an approved waste facility. NOTE: Dispose of all wastes in accor­ dance with local regulations.

6.HANDLING AND STORAGE:

Store in a cool, dry, ventilated storage area with acid resistant floors and good drainage. Protect from physical damage. When diluting, the acid should always be added to water slowly and in small amounts. Never use hot water and never add water to the acid. Water added to acid can cause uncontrolled boiling and splashing. When opening metal containers, use non-sparking tools because of the possibility of hydrogen gas being present .

7.EXPOSURES CONTROL AND PERSONAL PROTECTION:

Ventilation and engineering controls : Provide exhaust ventilation or other engi­ neering controls to keep the airborne concentrations of vapors below their re­ spective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the work-station location. Respiratory protection (type) : Wear NIOSH approved respiratory protection. If the exposure limit is exceeded, a full face piece respirator with an acid gas car­ tridge may be worn.

Eye protection (type) : Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area. Gloves (specify material) : Rubber or plastic chemical resistant gloves. Other clothing and equipment : addition­ al protection including impervious boots, apron Or coveralls, as needed in areas of unusual exposure to prevent skin contact Work practices, hygienic practices : Maintain good housekeeping standards. Wash hands thoroughly before handling food stuffs, liquids or tobacco products. Use common sense and care around chemicals. Never mix this product with other chemicals. Consult your supervisor For all other hygienic and safety prac­ tices. Other handling and storage require­ ments: Consult a specialist BEFORE han­ dling this product. Protective measures during maintenance of contaminated equipment.

HOW TO DETECT THIS SUBSTANCE (Warning properties of substance as a gas, vapor, dust, or mist): N/ A.

9.REACTIVITY DATA:

Stability : Stable Conditions to avoid Heat and direct sunlight. Incompatibility (materials to avoid): Incompatible with metals, metal oxides, hydroxides, amines, carbonates and other alkaline materials. Hazardous decomposition products (Including combustion products): (from burning, heating, or reaction with other materials) : When heated to decomposi­ tion, emits toxic hydrogen chloride fumes and will react with water or steam to pro­ duce heat and toxic and corrosive fumes. Thermal oxidative decomposition produces toxic chlorine fumes and explo­ sive hydrogen gas. Hazardous polymerization : Will not occur.
