Exposure Controls/Personal Protection

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)

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: Water or foam may cause frothing. Use water spray to cool fire-exposed containers. In case of fire use water spray, dry chemical, carbon dioxide, or chemical foam.
