PASS® Emulsion: Polymerized Asphalt Surface Sealer

 

Afton PASS flag-1PASS-CR is a high-performance emulsion produced and sold by Asphalt Systems, Inc. It is especially effective at treating deteriorated pavements, and offers a triple treatment in one: crack sealing, rejuvenating, and chip sealing/scrub sealing. It can be used in cool temperatures, lasts much longer than traditional chip seal oils, and provides exceptional chip retention. 

ASI has been a licensed manufacturer of PASS-CR for over 15 years, marketing to cities and counties throughout the Utah, Wyoming and Idaho regions.

CAUTION: There maybe the possibility of volatile vapors developing under extreme heat conditions while being stored in bulk containers.

 

3) Overview & Health Information

PASS – CR contains petroleum asphalt. After the water has been removed from the product, the residue may burn when exposed to direct and continuous flame. Petroleum asphalt forms fumes when heated. These fumes may cause irritation to the nose, throat and respiratory tract. Fumes have not been determined to be cancer causing.

Spill or leak procedures

Dike or contain spill with, floor dry, sand, etc. Pump liquid to containers or storage vessel. Soak up residue with absorbent material. Scoop contaminated absorbent and diking material into containers for disposal.

Waste Disposal :

Recovered materials may be blended with aggregate and used for patching or other maintenance use. Other wastes should be disposed of according to federal, state, and local regulations.

Protective equipment to be used

Respiratory Protection : NIOSH approved cartridge respirator with organic vapor cartridges if other controls are not effective.

Ventilation : Normal ventilation is usually adequate.

Protective Gloves : Impervious gloves such as neoprene or vinyl.

Eye Protection : Wear chemical safety goggles if splashing may occur.

Other Protective Equipment : Wear a protective apron if splashing or repeated contact is likely.
