Potential Acute Health Effects:

Hazardous in case of skin contact (irritant), of ingestion. Slightly hazardous in case of skin contact (corrosive), of eye contact

(irritant), of inhalation. Prolonged exposure may result in skin burns and ulcerations. Over-exposure by inhalation may cause

respiratory irritation.

in case of ingestion. Non-hazardous in case of inhalation. CARCINOGENIC EFFECTS: Classified A1 (Confirmed

for human.) by ACGIH [Silver Chromate ]. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not

available. DEVELOPMENTAL TOXICITY: Not available. The substance is toxic to lungs, mucous membranes. Repeated or

prolonged exposure to the substance can produce target organs damage.

 

Section 4: First Aid Measures

Eye Contact: Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Cold water may be

used.

Skin Contact:

After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin with running

water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cold water may be used.

Cover the irritated skin with an emollient. If irritation persists, seek medical attention.

Serious Skin Contact:

Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical attention.

Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.

Serious Inhalation:

Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If

breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical

attention.

Ingestion:

Do not induce vomiting. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform

mouth-to-mouth resuscitation. Seek immediate medical attention.
