========================================================================
HEALTH HAZARD DATA
========================================================================
Carcinogenic Data: n-Butyl Chloride is not listed as a carcinogen by IARC, NTP, OSHA, or ACGIH.
Primary Routes of Entry:
N-Butyl Chloride may exert its effects through inhalation, skin absorption, and ingestion.
Industrial Exposure: Route of Exposure/Signs and Symptoms
Inhalation: Exposure can cause depression or stimulation of the central nervous system.
Eye Contact: Liquid and high vapor concentration can cause irritation.
Skin Contact: Prolonged or repeated skin contact can cause mild irritation and dermatitis through defatting of skin.
Ingestion: Can cause gastrointestinal tract discomfort.
Effects of Overexposure:
N-Butyl Chloride is a mild irritant. Acute exposure irritates the eyes and upper respiratory tract. Chronic toxicity
properties have not been adequately determined.
Medical Condition Aggravated by Exposure: Preclude from exposure those individuals susceptible to dermatitis.

FIRST AID MEASURES
========================================================================
Inhalation:
Immediately remove to fresh air. If not breathing, administer mouth-to-mouth rescue breathing. If there is no pulse,
administer cardiopulmonary resuscitation (CPR). Contact physician immediately.
Eye Contact: Rinse with copious amounts of water for at least 15 minutes. Get emergency medical assistance.
Skin Contact:
Flush thoroughly for at least 15 minutes. Wash affected skin with soap and water. Remove contaminated clothing
and shoes. Wash clothing before re-use, and discard contaminated shoes. Get emergency medical assistance.
Ingestion:
Call local Poison Control Center for assistance. Contact physician immediately. Never induce vomiting or give
anything by mouth to a victim unconscious or having convulsions.
========================================================================
PREVENTATIVE MEASURES
========================================================================
Ventilation:
Adequate ventilation is required to protect personnel from exposure to chemical vapors exceeding the PEL and to
minimize fire hazards. The choice of ventilation equipment, either local or general, will depend on the conditions of
use, quantity of material, and other operating parameters.
Respiratory:
Use approved respirator equipment. Follow NIOSH and equipment manufacturer's recommendations to determine
appropriate equipment (air-purifying, air-supplied, or self-contained breathing apparatus).
Eyes:
Safety glasses are considered minimum protection. Goggles or face shield may be necessary depending on quantity
of material and conditions of use.
Skin:
Protective gloves and clothing are recommended. The choice of material must be based on chemical resistance and
other user requirements. Generally, neoprene or nitrile rubber offers acceptable chemical resistance. Individuals
who are acutely and specifically sensitive to n-Butyl Chloride may require additional protective equipment.
Storage:
N-Butyl Chloride should be protected from temperature extremes and direct sunlight. Proper storage of n-Butyl
Chloride must be determined based on other materials stored and their hazards and potential chemical
incompatibility. In general, n-Butyl Chloride should be stored in an acceptably protected and secure flammable
liquid storage room.
Other:
Emergency eyewash fountains and safety showers should be available in the vicinity of any potential exposure.
Ground and bond metal containers to minimize static sparks.

ENVIRONMENTAL PROTECTION DATA
========================================================================
Spill Control:
Protect from ignition. Wear protective clothing and use approved respirator equipment. Absorb spilled material in
an absorbent recommended for solvent spills and remove to a safe location for disposal by approved methods. If
released to the environment, comply with all regulatory notification requirements. CERCLA Reportable Quantity:
None.
