Hazards and Protection.
Storage
Store in a cool, dry place. Store in a tightly closed container.
Handling
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Use only in a chemical fume hood.
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.
Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.

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.
Fire potential
Slight when exposed to heat or flame.
Combustion products
Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.

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.
   Ingestion
Ingestion of large amounts may cause gastrointestinal irritation. May cause central nervous system depression.
   Inhalation
May cause respiratory tract irritation.
   Skin
May cause mild skin irritation.
   Eyes
May cause mild eye irritation. Causes redness and pain.

First aid
 
   Ingestion
Get medical aid. Wash mouth out with water.
   Inhalation
Remove from exposure to fresh air immediately. Get medical aid.
   Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
