SECTION 4: First aid measures
4.1 Description of first aid measures
First-aid measures after inhalation
Move to fresh air. If symptoms persist, seek medical attention.
First-aid measures after skin contact
Wash with soap and water. Seek medical attention if irritation develops.
First-aid measures after eye contact
Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek medical attention.
First-aid measures after ingestion
Do not induce vomiting. Rinse mouth and seek medical attention immediately.
4.2 Most important symptoms and effects, both acute and delayed
Symptoms relating to use
Irritation of eyes, skin, and respiratory tract; potential for chemical burns.
4.3 Indication of any immediate medical attention and special treatment needed
General information
Treat symptomatically. Show this safety data sheet to the treating physician.
SECTION 5: Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
Water spray, carbon dioxide, dry chemical powder, foam.
Unsuitable extinguishing media
Not specified
5.2 Special hazards arising from the substance or mixture
Special procedures
Since a calcium hypochlorite fire will generate its own oxygen, attempts to smother it will not be effective, and it must be quenched with water.
5.3 Advice for firefighters
Protection during firefighting
Do not enter fire area without proper protective equipment, including respiratory protection.
SECTION 6: Accidental release measures
6.1.1 For non-emergency personnel
Emergency procedures
Contain spill and prevent entry into waterways. Use appropriate protective equipment.
6.3 Methods and material for containment and cleaning up
Methods for cleaning up
Personal protection: chemical protection suit, face shield and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered air-tight, dry containers. Then store and dispose of according to local regulations.
