Ingredient: STODDARD SOLVENT
Ingredient Sequence Number: 01
Percent: 100
CAS Number: 8052-41-3
OSHA PEL: 500 PPM
ACGIH TLV: 100 PPM
18
Definition: Threshold Limit Value

TLV (TWA) is an 8-hour time-weighted
average believed to be the average
concentration to which 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.
