SECTION V - HEALTH HAZARD DATA

GENERAL

The primary toxicity of this material would be expected to

be associated with the nuisance dust characteristics of the

chemical mixture. Neither of the two chemical components of the

product are listed by any of the primary regulatory or research

agencies precursors (i.e., styrene and acrylic acid) of the

styrene acrylic resin are recognized to be toxic, there are no

data in the open scientific literature which indicate a toxicity

associated with this resin, itself. This absence of toxicity is

consistent with a general absence of recognized toxicity

associated with polymers of these monomeric precursors. A review

by the IARC of related polymers of these two monomers was

uniformally negative. Hence, the primary toxicologic

considerations for the toner material are associated with the

nuisance dust properties of airborne inhalation.

EMERGENCY/FIRST AID PROCEDURES

Eye Exposure

Flush eyes immediately with large amounts of water, lifting

the upper and lower lids occasionally. If irritation is present

after washing, seek medical attention.

Skin exposure

If material gets on skin, promply wash contaminated skin

using soap or mild detergent and water. If irritation persists

after washing, get medical attention.

Inhalation

If a person breathes in large amounts of material, move the

exposed person to fresh air at once. If breathing has stopped,

perform artificial respiration. Keep the affected person warm

and at rest. Get medical attention as soon as possible. Inform

the treating physician of the information contained in this

material safety data sheet.

Ingestion

When material has been swallowed, get medical attention

immediately. As above, inform the treating physician of the

information contained in this material safety data sheet.
