Potential Health Effects  

Inhalation:  

Corrosive. Extremely destructive to tissues of the mucous membranes and upper respiratory tract.  Symptoms may include burning sensation, coughing, wheezing, laryngitis, and shortness of breath,  headache, nausea and vomiting. Inhalation may be fatal as a result of spasm inflammation and  edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.  

Ingestion:  

Corrosive. Swallowing can cause severe burns of the mouth, throat, and stomach. Can cause sore  throat, vomiting, diarrhea.  

Skin Contact:  

Corrosive. Symptoms of redness, pain, and severe burn can occur 

Eye Contact: 

Corrosive. Contact can cause blurred vision, redness, pan and severe tissue burns. Chronic Exposure: 

Repeated exposures to calcium hypochlorite may cause bronchitis to develop with cough and/or  shortness of breath. 

Aggravation of Pre-existing Conditions: 

No information found.  

4. Acetic Acid – FIRST-AID MEASURES 

Inhalation:  

Remove to fresh air. IF not breathing, give artificial respiration. If breathing is difficult, give oxygen.  Get medical attention immediately.  

Ingestion:  

If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by  mouth to an unconscious person. Get medical attention immediately.  

Skin Contact:  

Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated  clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly  clean shoes before reuse.

Eye Contact:  

Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids  occasionally. Get medical attention immediately.  

Fire:  

Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or  combustibles may cause ignition. Thermally unstable; at higher temperatures, may undergo  accelerated decomposition with release of heat and oxygen.  

5. FIRE FIGHTING MEASURES 

Explosion:  

Sealed containers may rupture when heated. An explosion can occur if either a carbon tetrachloride  or a dry ammonium compound fire extinguisher is used to extinguish a fire involving calcium  hypochlorite.  

Fire Extinguishing Media:  

Use flooding quantities of water as fog or spray. Use water spray to keep fire-exposed containers  cool. Avoid direct contact with water; reacts with water releasing chlorine gas. Fight fire from  protected location or maximum possible distance. Do not use dry chemical fire extinguishers  containing ammonium compounds. Do not use carbon tetrachloride fire extinguishers. Do not allow  water runoff to enter sewers or waterways. 

Special Information: 

In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing  apparatus with full-face piece operated in the pressure demand or other positive pressure mode.  

6. ACCIDENTAL RELEASE MEASURES 

Remove all sources of ignition. Keep water away from spilled material. Ventilate area of leak or spill.  Wear appropriate personal protective equipment as specified in Section 8.  

Spills:  

Remove all sources of ignition. Clean up in manner to minimize contamination with organic material.  Do not return material to original container. Place in a fresh container and isolate outside or in a  well-ventilated area. Do not seal the container. Flush any residual material with large quantities of  water. In the event of a large spill use the emergency telephone number.

7. Acetic Acid – HANDLING AND STORAGE 

Handling:  

Avoid inhalation of dust and fumes. Do not take internally. Avoid contact with skin, eyes and clothing.  Upon contact with skin or eyes, wash off with water. Remove contaminated clothing and wash before  reuse.  

Storage:  

Keep product tightly sealed in original containers. Store product in a cool, dry and well ventilated  area. Store away from combustible or flammable products. Keep product packaging clean and free of  all contamination, including e.g. other pool treatment products, acids, organic materials, nitrogen containing compounds, dry powder fire extinguishers (containing mono-ammonium phosphate),  oxidizers, all corrosive liquids, flammable or combustible materials, etc.  

Shelf Life Limitations:  

Do not store product where the average daily temperature exceeds 35°C / 95°F. Storage above this  temperature may result in rapid decomposition, evolution of chlorine gas and heat sufficient to ignite  combustible products. Shelf life (that is, the period of time before the product goes below stated label  strength) is determined by storage time and temperatures. Store in cool, dry and well ventilated area.  Prolonged storage at elevated temperatures will significantly shorten the shelf life. Storage in a  climate controlled storage area or building is recommended in those areas where extremes of high  temperature occur.  

Incompatible Materials for Storage:  

Do not allow product to come in contact with other materials, including e.g. other pool treatment  products, acids, organic materials, nitrogen-containing compounds, dry powder fire extinguishers  (containing mono-ammonium phosphate), oxidizers, all corrosive liquids, flammable or combustible  materials, etc. A chemical reaction with such substances can cause a fire of great intensity.  

Do Not Store at Temperatures Above:  

Average daily temperature of 35°C / 95°F. Storage above this temperature may result in rapid  decomposition, evolution of chlorine gas and heat sufficient to ignite combustible products.  

8. EXPOSURE CONTROL / PERSONAL PROTECTION 

Airborne Exposure Limits:  

None established  

Ventilation System:  

A system of local and/or general exhaust is recommended to keep employee exposures as low as  possible. Local exhaust ventilation is generally preferred because it can control the emissions of the  contaminant at its source, preventing dispersion of it into the general work area. Please refer to the Page 4 of 9

ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition,  for details.  

Personal Respirators (NIOSH Approved):  

For conditions of use where exposure to the dust or mist is apparent, a half-face dust/mist respirator  may be worn. For emergencies or instances where the exposure levels are not known, use a full face positive-pressure, air-supplied respirator.  

WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.  Skin Protection:  

Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as  appropriate, to prevent skin contact.  

Eye Protection:  

Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye  wash fountain and quick-drench facilities in the work area.
