Health Effects
|
|
| CAUTION: Do not allow contact with eyes or skin. Contains concrete aggregates sand/gravel (CAS# 14808-60-7). Avoid breathing dust. Respirable silica may cause serious lung problems. There is limited evidence silica is a carcinogen. The use of gloves, goggles, and where appropriate, dust masks and other protective clothing is recommended. |

HEALTH HAZARDS
Skin or eye contact with molten asphalt can cause severe thermal burns. Vapors can irritate the eyes or skin. Inhalation of asphalt fumes can cause nausea and irritation of the nose and throat. Exposure to asphalt fumes can cause dermatitis and can photosensitize the skin. CAUTION: Under certain
circumstances, Hydrogen sulfide, a highly flammable and toxic gas, may be released from molten asphalt. Low concentrations (50-100 ppm) can irritate the eye and respiratory tract, and may cause nervousness, cough, nausea and headache. Prolonged exposures to concentrations between 250-600 ppm, may cause pulmonary edema ( fluid in the lungs) and bronchial pneumonia. Brief exposure to concentrations above 500 ppm can cause unconsciousness and may be fatal.
Medical Conditions Generally Aggravated by Exposure
Inhalation of respirable dust may aggravate existing respiratory tract diseases. Exposure may aggravate existing or skin conditions.

From MSDS
This product may contain crystalline silica, as do virtually all other sand and stone products. Prolonged or repeated inhalation of crystalline silica can cause scarring of the lungs or a progressive lung disease called silicosis. The symptoms include coughing, difficulty breathing, wheezing, and impairment
of pulmonary function. The symptoms of silicosis tend to worsen with continued exposure to dust containing free silica, with advancing age, and with cigarette
smoking. IARC has classified crystalline silica as a Group 2A potential human carcinogen and considers it to be carcinogenic in certain experimental animals.
The carcinogenicity of crystalline silica in humans is neither certain nor proven; IARC concluded that there is insufficient evidence to consider silica to be
carcinogenic to humans. Either silicosis or lung cancer may lead to permanent injury or loss of life.

EYE: If hot material splashes into eyes, immediately flush eyes with copious amounts of water. Do not attempt to remove particles from eyes. Take victim to physician at once.
SKIN: If molten asphalt contact the skin, cool immediately by quenching with
cold water. For extensive burns, cover with a sterile dressing and obtain medical attention at once. Do not use solvents to remove asphalt from skin.
INHALATION: Remove to fresh air. If breathing is difficult, administer oxygen. If breathing has stopped, give artificial respiration. Seek medical attention.

Handling/Disposal
|
From MSDS
Avoid breathing fumes. Contact can cause severe burns. Use in well ventilated areas. Dusts created by drilling or grinding cured asphalt may irritate the eyes and respiratory tract. For such operations, use approved respirators and avoid breathing dusts. Highly flammable and toxic fumes may build up in vapor spaces of storage tanks and transport compartments. Avoid breathing gases and keep ignition sources away from vents.
