TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Sore throat. Burning sensation. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes).
Local exhaust or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
•SKIN Skin burns. Pain. Redness.
Protective gloves.
Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Pain. Redness. Severe deep burns.
Safety goggles or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal pain. Burning sensation in the throat and chest. Sore throat. Nausea. Vomiting. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC WHITE SOLID IN VARIOUS FORMS

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes of hydrogen chloride and zinc oxide. The solution in water is a medium strong acid.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as fume) 1 mg/m3 as TWA; 2 mg/m3 as STEL; (ACGIH 2004).
MAK: (as fume) IIb (not established but data is available) (DFG 2004).
OSHA PEL†: TWA 1 mg/m3
NIOSH REL: TWA 1 mg/m3 ST 2 mg/m3
NIOSH IDLH: 50 mg/m3 See: 7646857


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes and the skin. The aerosol is irritating to the respiratory tract . Corrosive on ingestion. Inhalation of fume of this substance may cause lung oedema (see Notes). The substance may cause effects on the pancreas, if ingested. Acute exposure to high concentrations of zinc chloride fume can lead to Adult Respiratory Distress Syndrome leading to pulmonary fibrosis and death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

Melting point: 290°C
Density: 2.9

Solubility in water, g/100 ml at 25°C: 432
very good

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.

N O T E S

Other UN: 1840 Zinc chloride solution, Hazard Class 8. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Card has been partly updated in October 2004 and 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
