Eye: Causes eye burns. May result in corneal injury. May cause blepharitis (inflammation of the
margins of the eyelids).
Skin: Causes severe burns with delayed tissue destruction.
REAGENTS, INC.--MSDS鈥擟ALCIUM HYPOCHLORITE PAGE -2-
Ingestion: May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract
burns. May cause perforation of the digestive tract. May be harmful if swallowed.
Inhalation: Causes chemical burns to the respiratory tract. Aspiration may lead to pulmonary edema.
May cause systemic effects. Causes corrosive action on the mucous membranes.
Chronic: Prolonged or repeated skin contact may cause dermatitis. Prolonged or repeated eye contact
may cause conjunctivitis. Effects may be delayed. Laboratory experiments have resulted in mutagenic
effects.
4. First Aid Measures
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention for any breathing difficulty.
Ingestion: Give large amounts of water to drink. Never give anything by mouth to an unconscious
person. Get medical attention for any gastrointestinal irritation.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention if symptoms occur.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get medical attention for any irritation.
5. Fire Fighting Measures
Autoignition Temperature: Not available.
Flash Point: Not available.
Explosion Limits, Lower: Not available.
Upper: Not available.
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.
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. Sensitive to mechanical impact.
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand,
MSHA/ NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with
combustible materials may cause a fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers
cool. Use water with caution and in flooding amounts. Contaminating or mixing with foreign materials
such as combustibles, grease, and fuels can cause fire. Containers may explode when heated.
Extinguishing Media: Use water spray to cool fire-exposed containers. Contact professional fire-
fighters immediately. Cool containers with flooding quantities of water until well after fire is out. For
small fires DO NOT use dry chemicals, carbon dioxide, halon or foams. USE WATER ONLY. For large
fires, flood fire area with water from a distance.
6. Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
REAGENTS, INC.--MSDS鈥擟ALCIUM HYPOCHLORITE PAGE -3-
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff
into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing
precautions in the Protective Equipment section. Avoid generating dusty conditions. Remove all sources
of ignition. Provide ventilation. Do not get water inside containers. Do not use combustible materials
such as paper towels to clean up spill.
7. Handling and Storage
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use
only in a well ventilated area. Minimize dust generation and accumulation. Do not get in eyes, on skin,
or on clothing. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid contact
with clothing and other combustible materials. Do not ingest or inhale. Discard contaminated shoes.
Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store
near combustible materials. Keep container closed when not in use. Store in a tightly closed container.
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from acids.
8. Exposure Controls/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 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. Maintain eye wash fountain and quick-drench facilities in
work area.
