B2Last® - Health and Safety
B2Last Product Safety and Handling
BASF has conducted significant reviews and analysis to ensure that its new liquid asphalt modifier, B2Last, is compliant with Environmental Protection Agency (EPA) regulations and can be used appropriately in accordance with Toxic Substances Control Act (TSCA) provisions. It is BASF’s technical assessment that the use of B2Last does not pose any unique hazards to asphalt industry personnel beyond what is currently encountered in an asphalt operating environment. B2Last in fact poses less health risks than many materials currently in use by the asphalt industry.
B2Last technical support teams are prepared to work with you and your team to provide environmental health and safety (EHS) training and can work with your firm to provide guidance on and setting up an ongoing monitoring program at your discretion.
B2Last Liquid asphalt modification when handled as instructed also does not require any unique personnel protective equipment (PPE). BASF in multiple trials conducted in North America and Europe has conducted monitoring for volatile organic compounds (VOC’s) and hazardous fumes. In fact, many commonly accepted asphalt modifiers and additives require more care in handling than B2Last.
We value the health and safety of people above all else – in all plant trials, we instruct our customers on safe processing and handling the product. The training is based on legal requirements (GefStoffV) and the information provided by ISOPA (European Diisocyanate and Polyol Producers Association). In summary, however, it can be said that no more safety equipment is required for proper use of B2Last at the asphalt mixing plant than for products already established in the industry. The product emissions are also recorded during the manufacturing and processing steps of B2Last modified mixtures. Here, the numerous measurements in practice confirm that the emissions produced during the manufacturing of modified mixtures with B2Last are significantly below those of the maximum permitted workplace concentrations.
More Information
All employees handling products containing free diisocyanates in concentrations of 0.1 percent and above need to complete a mandatory training until 2023 (see EUR-Lex at the European Union's website). We cooperated with the European Diisocyanate & Polyol Producers Association (ISOPA), the European Aliphatic Isocyanates Producer Association (ALIPA), and several other associations of the polyurethane industry to set up a comprehensive training program for fulfilling the obligations from the restriction.
