2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute
Swallowed
Single dose oral toxicity is low. Ingestion may cause gastrointestinal irritation or ulceration.
Eye
May cause moderate to severe eye irritation with corneal injury, which may be slow to heal. When dissolving, the heat produced
may cause more intense effects as well as thermal burns.
Skin
Short single exposure not likely to cause significant skin irritation. Prolonged or repeated exposure may cause skin irritation, even
a burn. May cause more severe response if skin is damp and/or abraded, or if material is confined to skin. When dissolving, the
heat produced may cause more intense effects as well as thermal burns.
Inhaled
Vapours are unlikely due to physical properties. Dust may cause irritation to upper respiratory tract.
2.2 Health Effects - Chronic
The components of this product are not listed by IARC, NTP or PSHA as a carcinogen for hazard communication purposes.
Results of in vitro mutagenicity tests have been negative for calcium chloride.
2.3 First Aid
Swallowed
If swallowed, induce vomiting immediately by giving two glasses of water and sticking finger down throat. Call a physician. (Never
Page 3 of 5 by mouth or attempt to induce vomiting in an unconscious person.)
give anything
Eye
Irrigate with flowing water immediately and continuously for 15 minutes. Consult medical personnel.
Skin
Wash off in flowing water or shower. If condition persists, seek medical attention.
Inhaled
Remove to fresh air if effects occur. Consult a physician.
First Aid Facilities
Ensure and eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
If burn is present, treat as any thermal burn, after decontamination. No specific antidote. Supportive care. Treatment based on
judgement of the physician in response to reactions of the patient.
2.6 Toxicity Data
Oral LD50 = 1000 mg/kg (Rat)
Dermal LD50 = 1384 mg/kg (Rabbit)
Inhalation LC50 = not available
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TLV: 10 mg/m3 (dust)
3.2 Engineering Controls
Ensure adequate ventilation to maintain exposure levels below standards.
3.3 Personal Protection
Use an approved air-purifying respirator. In dusty atmospheres, use an approved dust respirator. Wear protective clothing.
Selection of specific items such as gloves, boots, apron, or full-body suit will depend on operation. Safety glasses should be
sufficient for most operations, however for dusty operations or when handling solutions of the material, wear chemical goggles.
3.4 Flammability
Material is non-flammable

4.3 Spills and Disposal
Spills
No special precautions need to be taken.
Disposal
Observe all Local, State and Federal regulations before you dispose of small quantities to the sewer, or add sludge to landfill.
4.4 FIRE AND EXPLOSION HAZARD
Fire / Explosion
Will not burn or explode. Calcium chloride will : corrode most metals exposed to air; attack aluminium (and its alloys) and yellow
brass; react with sulphuric acid to form hydrogen chloride which is corrosive, irritating and reactive; give an exothermic reaction
with water-reactive materials such as sodium; result in a runaway polymerisation reaction with methyl vinyl ether (Bretherick,
1979); and, in solution form react with zinc (galvanising) to yield hydrogen gas which is explosive. (Bretherick, L., 1979, Handbook
of Reactive Chemical Hazards, 2nd ed.). Hazardous polymerisation will not occur.
Extinguishing Media
Summon Fire Brigade immediately, dial 000 Wear positive pressure self-contained breathing apparatus. Remove from the vicinity
containers NOT involved in fire. Use equipment/media appropriate to surrounding conditions. Water may be effective for cooling
containers.
