Hazards and Protection.
Storage
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Storage under a nitrogen blanket has been recommended.
D1A D2B
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get on skin or in eyes. Avoid ingestion and inhalation.
Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. 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
Wear a self contained breathing apparatus and appropriate Personal protection. (See Exposure Controls, Personal Protection section). Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Carefully scoop up and place into appropriate disposal container.

Exposure effects
May cause fetal effects. May cause cancer in humans.
   Ingestion
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause systemic toxicity with acidosis. May cause effects similar to those for inhalation exposure.
   Inhalation
Effects may be delayed. Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Irritation may lead to chemical pneumonitis and pulmonary edema. May cause liver and kidney damage. May cause heart disturbances, possibly leading to cardiac arrest and death. May cause lung damage.
   Skin
Causes severe skin irritation. Harmful if absorbed through the skin. May cause skin burns.
   Eyes
Causes severe eye irritation. May result in corneal injury.

First aid
 
   Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. Get medical aid.
   Skin
Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
