## Abstract

The Occupational Safety and Health Administration (OSHA) is extending the start-up date for most provisions of the methylene chloride standard for larger employers by 45 days to December 21, 1997. Larger employers were required to commence initial monitoring by September 7, 1997, and that date is unchanged. OSHA is also extending the start-up date for initial monitoring for foam manufacturers with 20 to 99 employees by 45 days to December 21, 1997, Employers with fewer than 20 employees have later start-up dates, which are not changed.
