４． First aid

When inhaled:
  1. Move to a place with fresh air and rest in a comfortable posture. Cover your body with a blanket, keep warm and rest, and receive medical attention immediately.
  2. If breathing stops or is weak, loosen clothing to secure a breathing airway and then give artificial respiration.
  3. Straight asphalt may generate hydrogen sulfide / carbon monoxide when heated. Inhalation of mist / smoke / vapor / fume generated during heating and melting may cause symptoms such as headache, dizziness, and nausea. Therefore, move as quickly as possible from potentially contaminated areas and wear an air respirator when entering such areas.
If it adheres to the skin: ・Cool with plenty of water until it is no longer tingling, do not remove the product adhering to the skin, and seek medical attention.
If it gets in your eyes: ・Carefully wash with clean water for a few minutes. Next, if you are wearing contact lenses and can easily remove them, remove them. Continue washing, wash for at least 15 minutes, and then seek medical attention.
If swallowed: ・Get a doctor's diagnosis promptly without forcibly spitting. If the mouth is contaminated, wash thoroughly with water.
The most important subtle signs of acute and delayed symptoms: ・Straight asphalt products may generate hydrogen sulfide / carbon monoxide when heated.
・Hydrogen sulfide causes symptoms such as headache, dizziness, vomiting and diarrhea when inhaled above the permissible exposure concentration (10ppm). At 400-700 ppm, exposure for 30 minutes to 1 hour may result in acute death or post-mortem, and inhalation of hydrogen sulfide above 700 ppm causes respiratory paralysis leading to unconsciousness and death.
As a measure of poisoning, carbon monoxide has a small effect at <300 ppm, a mild effect at <600 ppm, and a medium to high effect at 900 ppm.
Serious symptoms appear at 1000 ppm and above, and life-threatening at 1500 ppm and above.

・ No useful information on respiratory sensitization at present
Germ cell mutagenicity: -There are various test results using asphalt fume or asphalt fume condensate, asphalt paint, etc., and there are positive / negative data on germ cell mutagenicity. However, the positive results of the in vivo somatic cell mutagenicity test / somatic cell genetic toxicity test, the positive results of the in vitro mutagenicity test, and the description that this substance is mutagenic are comprehensively considered and classified. It was set to 2.
carcinogenic: -Regarding long-term occupational exposure to "asphalt emissions" from straight asphalt such as road pavement, IARC classifies it as "Group 2B" (potential for carcinogenesis in humans). In addition, IARC defines "asphalt emissions" as "heated and vaporized substances and gases, and asphalt that has become gases aggregate in the air to form small particles and become clouds", and "road pavement". Is stipulated as "work related to asphalt mixture production, transportation, and pavement", and "occupational exposure" is stipulated as "workers are exposed to about 4 to 9 hours a day for a long period of time".
-EU CLP Regulation (1272/2008 / EC) Annex VI Not listed in Table 3.1 and Table 3.2. (Not classified as harmful)
Reproductive toxicity ・ Currently no useful information
Specific target organ
/ systemic toxicity (single exposure)		 ・ 200 mg of needle-filled asphalt was subcutaneously injected into black rat every 3 months, but no skin tumor was found on the anatomical findings.
-It is known that hydrogen sulfide / carbon monoxide contained in asphalt fume has airway irritation.
Specific target organ
/ systemic toxicity (repeated exposure)		 -Data on the harmfulness of the substance in a nearly solid state at room temperature cannot be confirmed.
Inhalation test of asphalt fume (mice, 6-7 h / day, 5 days / week for 21 months) showed tracheal infiltration, bronchitis, pneumonia, abscess, ciliary loss, epithelial atrophy and skin thickening.
-In humans, rhinitis, sore throat, laryngitis, bronchitis, dermatitis, acne-like lesions, and mild keratosis have been reported by percutaneous exposure to fume. In addition, in experimental animals, an effect on the respiratory organs was observed in an inhalation toxicity test using mice, but the exposure concentration was not described and it could not be used for classification.
-Since the respiratory system is affected in humans, it was classified as Category 1 (respiratory system).
Inhalation Respiratory Harm: Since the kinematic viscosity is 8000 mm2 / s or more, it is out of the category.
others:

At 400-700 ppm, exposure for 30 minutes to 1 hour may result in acute death or post-mortem, and inhalation of hydrogen sulfide above 700 ppm causes respiratory paralysis leading to unconsciousness and death. As a measure of poisoning, carbon monoxide has a small effect at ＜300 ppm, a mild effect at ＜600 ppm, and a medium to high effect at 900 ppm. Serious symptoms appear at 1000 ppm and above, and life-threatening at 1500 ppm and above.

１２．Environmental impact information

Ecotoxicity: ・Currently no useful information
Persistence / Degradability: -Persistent
asphalt does not evaporate at room temperature, but generates fume when heated for construction such as road pavement and roof waterproofing. The generated fume immediately condenses, settles and adsorbs to the soil. The volatile components of fume react with hydroxyl radicals in the atmosphere. In water, asphalt is poorly dispersible and either floats or sinks. There is no mobility in the soil. -There are no studies on the biodegradability of
biodegradable asphalt in the aquatic environment.
However, from the experience of using it for road pavement and roof waterproofing for hundreds of years, asphalt is clearly a substance that lasts forever (does not decompose), and is also characterized by not being biodegradable.
Bioaccumulation: ・Since logKow, a component of asphalt, is 6 or more, it is judged to be bioaccumulative, but in reality, it is extremely sparingly soluble in water, and such high molecular weight substances are taken into the body of aquatic organisms. Is hard to think of.
Mobility in soil: ・There is no mobility in the soil.
Harmful to the ozone layer: ・No information
