Sustainability and regulatory concerns are driving companies to look for alternatives to traditional solvents like N-Propyl Bromide (NPB), 三氯乙烯 (吨标煤), and perchloroethylene (四氯乙烯/ PERC) for metal parts cleaning and degreasing. Hubbard-Hall has been helping manufacturers tackle these issues with lower-impact solvents or aqueous cleaning chemistries.
目前监管状态:2024年4月
- 三氯乙烯2023年10月, EPA proposed a risk management rule to address unreasonable risk posed by trichloroethylene (吨标煤) to human health, including the final revised risk determination for 吨标煤
- 全氯乙烯2023年6月, EPA proposed to ban most uses of 四氯乙烯 and establish a workplace chemical protection program (WCCP) for uses not prohibited to address the unreasonable risk to human health.
- nPB:又称1-溴丙烷(1-BP), 2022年12月, EPA released a final revised risk determination for 1-BP. 最终修订后的风险判定发现1-BP, 作为一个整体, presents an unreasonable risk of injury to health under its conditions of use. 1-溴丙烷的风险评价
- 二氯甲烷: EPA finalizes regulations under the TSCA to manage the risks associated with methylene chloride. The regulations include prohibitions on the manufacturing, 处理, and 分布 of methylene chloride for consumer uses. 另外, 大多数工业和商业用途, 包括油漆和涂层去除剂, 是被禁止的. Strict workplace protections are established through the Workplace Chemical Protection Program to ensure the safety of workers in remaining uses.
- 完成后18个月(预计2025年底)1: Workplaces will have approximately 18 months from April 2024 to comply with the Workplace Chemical Protection Program. 在此期间, they must implement stringent workplace controls and periodically monitor their environments to ensure that workers are not exposed to harmful levels of methylene chloride.
- 未来: EPA plans to hold webinars to educate stakeholders about the final risk management rule and will develop guides to help small businesses comply with the regulations. Opportunities for public and stakeholder engagement will be provided, including one-on-one meetings with EPA representatives and access to email alerts and public dockets for updates and information.
