· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Keep combustibles (wood, paper, oil, etc.) away from spilled material.

General First Aid:

· Wear positive pressure self-contained breathing apparatus (SCBA).

0.1 [mg/m3] (respirable fraction), 2 mg/m3 (inhalable fraction) for Zn inorg. cmpnds[German Research Foundation (DFG)]

If material on fire or involved in fire: Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. If fire becomes uncontrollable-consider evacuation of one-half mile radius.

Wear positive pressure self-contained breathing apparatus when fighting fires involving this material.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Do not handle broken packages without protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

WOOD SHOULD BE AVOIDED IN STRUCTURE & FLOORS OF BUILDINGS & IN PLANT OR EQUIPMENT WHERE CHLORATES ARE HANDLED ... A COPIOUS WATER SUPPLY SHOULD BE AVAIL FOR EXTINGUISHING FIRE. /CHLORATES/

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Anaemia results from the excessive absorption of zinc suppressing copper and iron absorption, most likely through competitive binding of intestinal mucosal cells. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase has been linked to amyotrophic lateral sclerosis (ALS). Stomach acid dissolves metallic zinc to give corrosive zinc chloride, which can cause damage to the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc. (L48, L49, A49)

Ingestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation. (L49)

When normal stimulated cultured human lymphocytes were pretreated with various soluble zinc salts, there was an increase in the numbers of cells with chromosomal fragmentation, diploidy, dicentrism, and chromatid gaps and breaks. A later study using a similar treatment regimen indicated that zinc induced a dose-dependent decrease in lymphocytic mitotic indices. /Soluble zinc salts/

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . /Chlorates and related compounds/

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Start an IV with D5W TKO /SRP: "To keep open", minimal flow rate/.
