Section 3: Hazards Identification

Potential Acute Health Effects:

Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Hazardous in

case of skin contact (corrosive, permeator), of eye contact (corrosive). The amount of tissue damage depends on

length of contact. Eye contact can result in corneal damage or blindness. Skin contact can produce inflammation

and blistering. Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract, characterized by

burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking, unconsciousness or

death. Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation is

characterized by itching, scaling, reddening, or, occasionally, blistering.

Potential Chronic Health Effects:

CARCINOGENIC EFFECTS: Classified POSSIBLE by IRIS.

MUTAGENIC EFFECTS: Not available.

TERATOGENIC EFFECTS: Not available.

DEVELOPMENTAL TOXICITY: Not available.

The substance may be toxic to kidneys, lungs, liver, skin, central nervous system (CNS).

Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure of the

eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction,

or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage.

Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in

one or many human organs.

Section 4: First Aid Measures

Eye Contact:

Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at

least 15 minutes. Cold water may be used. Get medical attention immediately.

Skin Contact:

In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated

clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before

reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.

Serious Skin Contact:

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

medical attention.

Inhalation:

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get

medical attention immediately.

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

Special Remarks on other Toxic Effects on Humans:

Acute Potential Health Effects:

Skin: Causes severe irritation and burns. Skin contact with cresols has resulted in erythema (skin reddening),

blanching, blistering, skin peeling, burning sensation, localized anesthesia (numbness), and occasionally,

ochronosis, a darkening of the skin. It is also rapidly absorbed through the skin. When absorbed through the skin

it can produce systemic effects such as profound central nervous system (CNS) depression, seizures,

methemoglobinemia, pulmonary edema, damage to internal organs, such as the lungs, pancreas, spleen, heart,

and loss of kidney function and necrosis of the liver and kidneys. Serious or even fatal poisoning may result if

large areas of the skin are wet with cresol and it is not removed immediately. Hypersensitivity may also occur.

Eyes: Causes severe irritation and corneal burns, keratitis, and possibly, in severe cases, blindess.

Inhalation: It is extremely destructive to the tissue of the mucous membrane and upper respiratory tract.

Inhalation may result in spasm, inflammation, and edema of the larynx and bronchi, chemical pneumonitis, and

pulmonary edema. Symptoms may include burning sensation, coughing, wheezing, laryngitis, shortness of

breath, headache, nausea.

Ingestion: Can cause burning pain in mouth and throat. White necrotic lesions in mouth, esophagus, and

stomach, abdominal pain, peritonitis, nausea, vomiting, bloody diarrhea, dyspnea, pallor, sweating, central

nervous system disturbances (somnolence, convulsions, headache, dizziness), tinnitus. Acute ingestion may

lead to shock with cardiovascular disturbances (cardiac damage, weak irregular pulse, tachycardia, hypotension),

shallow respirations, cyanosis, pallor, profound fall in body temperature, possible fleeting excitement and

confusion followed by unconciousness. Other symptoms of acute ingestion may include stentorous breathing,
