Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
D2B
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Use chemical resistant apron, gloves, and other impervious clothing to avoid skin contact. Use splash goggles and face shield when eye contact may occur.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Clean-up personnel should wear full protective clothing to prevent skin and eye contamination and inhalation of vapors. Slippery when spilt. Prevent run off into drains and waterways. Remove sources of ignition, stop release, and provide adequate ventilation. Prevent flow to sewer and public waters. Recover free product, if possible. Cover spill with an inert, non-combustible absorbant material and remove to disposal container. Report spill as per regulatory requirements.
Stability
Stable.
Incompatibilities
Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides.
Decomposition
When heated to decomposition it emits acrid smoke and fumes.

Fire fighting
se carbon dioxide, foam or dry chemical to extinguish fire. Water fog can be used to cool a fire, but for extinguishing, foam or dry chemical are preferred. Avoid spreading liquid and fire by water flooding. Wear self-contained breathing apparatus and full fire-fighting protective clothing. Use water to keep containers cool.
Fire potential
Combustible liquid.
Hazards
Containers may explode when heated.
Combustion products
On burning will emit toxic fumes including carbon monoxide.

Exposure effects
The symptoms of lung edema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
   Ingestion
Swallowing can result in corrosion of the digestive tract.
   Inhalation
Not an inhalation hazard due to low vapor pressure at ambient temperatures. Inhalation of vapor from heated material is an irritant to mucous membranes and the respiratory tract.
   Skin
Contact with skin will result in severe irritation.
   Eyes
A severe eye irritant.

First aid
 
   Ingestion
If swallowed, DO NOT induce vomiting. Give victim a glass of water to drink. Call a physician immediately. Never give anything by mouth to an unconscious person.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
In case of skin contact, flush skin with plenty of mild soap and water. Remove contaminated clothing. Call a physician if irritation develops. Wash clothing before re-use. Destroy contaminated shoes.
   Eyes
In case of eye contact, flush eyes with plenty of water for at least 15 minutes. Get medical attention. (Nonyl phenol is almost totally insoluble in water so it will have to be flushed out of the eye).
