Road Crew Serious Ice Melting Crystals / Ice Melting

SECTION 2: Hazards identification

OSHA NFPA Hazard Rating (HMIS / NFPA): (Scale 0-4) HEALTH: 1 FLAMMABILITY: 0 REACTIVITY: 0 PERSONAL PROTECTION: B EMERGENCY OVERVIEW:

Appearance/Odor

White crystalline or granulated solid None REACTIVITY: Reacts with water to create heat (calcium chloride)

Principle Routes of Exposure

Skin Contact

Potential health effects

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 CONTACT: 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. DOT classification: Non-corrosive. SKIN ABSORPTION: A single prolonged exposure is not likely to result in the material being absorbed through the skin in harmful amounts. The LD50 skin absorption in rabbits is > 5000 mg/kg. INGESTION: Single dose oral toxicity is low. The oral LD50 for rats is in the range of 900-2100 mg/kg for calcium chloride in a 100% basis. Ingestion may cause gastrointestinal irritation or ulceration. Small amounts swallowed incidental to normal handling operations are not likely to cause injury; swallowing amounts larger than that may cause injury. INHALATION: Vapors are unlikely due to physical properties. Dust may cause irritation to upper respiratory tract. SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Results of in vitro mutagenicity tests have been negative for Calcium Chloride. IARC NTP or
