    carries a complete label and a material safety
    data sheet which meet the requirements of federal
    regulations, and the employees have received the
    training and information required to safely carry
    out the work entrusted to him/her.

    most workers can be exposed during an 8-hour
    workday, day after day, without harmful effects.
  • TLV (STEL) is a 15 minute short term exposure
    limit.
  • Ceiling (C) is a maximum concentration never to
    be exceeded.
