Anchor Glass Container Corporation and other producers and users of sodium sesquicarbonate (Trona) are seeking to prohibit ACGIH from publishing a Trona TLV. The Refractory Ceramic Fibers Coalition has filed a suit claiming that ACGIH is a standards-setting organization and that the TLV for synthetic vitreous fiber (specifically refractory ceramic fibers) is unreasonable and unjustified.

The third suit charges ACGIH and more than 20 other defendants of withholding evidence regarding vinyl chloride that led to the death of a worker.

ACGIH is concerned that the first two of these suits strike at the heart of whether ACGIH, or any other organization, can freely publish the results of its research.
