Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.

Skin

Causes skin irritation.

Eyes

Causes eye irritation.

Ingestion

May cause irritation of the digestive tract. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated.

Exposure Controls/Personal Protection

Personal 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

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure Effects

This compound's stimulant properties appear closely related to its mao inhibitor activity.

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Fire Potential

Flammable/combustible material. May be ignited by heat, sparks or flames.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Disposal Code

3

Stability

Stable at room temperature in closed containers under normal storage and handling conditions.

Incompatibilities

Strong oxidizing agents.

Decomposition

Hydrogen chloride, carbon monoxide, oxides of nitrogen, carbon dioxide.

Combustion Products

Fire will produce irritating, corrosive and/or toxic gases.
