Exposure Controls/Personal Protection	Back to Contents
【Personal Protection】 Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
【Respirators】 Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
【Exposure Effects】 With most exposures, one would not expect to see alternations in vital signs. However, with large oral or inhalation exposures, rapid breathing and rapid heart rate may be expected. Central nervous system depression might develop if large amounts are absorbed. At the time of this writing, there are not data on reproductive toxicity in humans from DEHP. Rodent studies suggest testicular atrophy.
【Exposure limit(s)】 NIOSH REL: Ca TWA 5 mg/m3 ST 10 mg/m3 See Appendix A OSHA PEL: TWA 5 mg/m3 IDLH Ca [5000 mg/m3]
