form. Exposure to fumes from melting operations may cause irritation . Contact with molten material will cause thermal burns. No other significant immediate health , physical or environmental hazards are associated with these materials.

POTENTIAL HEALTH HAZARDS:

SKIN: Prolonged or repeated exposure may cause irritation. Contact with molten material will cause thermal burns .

EYES: Contact with powder may cause mechanical irritation . Exposure to fumes may cause irritation.

INHALATION: Powder or fumes may cause irritation.

INGESTION: Not expected to occur .

DELAYED EFFECTS: None known.

Ingredients found on one of the OSHA designated carcinogen lists are listed below.

Ingredient Name NTP Status IARC Status OSHA List

* No ingredients listed in this section *

4.      FIRST AID MEASURES

SKIN: Wash thoroughly with water and soap ; if irritation develops , contact a physician . In case of contact with molten material , submerge injured area in cold water . Do not attempt to remove material adhering to the skin .Get immediate medical attention .

EYE: Flush eyes with large amounts of water . Get medical attention if irritation occurs.

INHALATION: For inhalation of powder or vapors, remove to fresh air. If breathing is difficult , get medical attention .

INGESTION: Not expected to occur.

ADVICE TO PHYSICIAN: No specific advice. Treat according to symptoms present. Burns from molten material can be treated as normal thermal burns .
