ISO-BUTYL ACRYLATE 57
Headaches, dizziness, nausea, irritation of respiratory passage and eyes; General Treatment for
Exposure: INHALATION: if victim is overcome by vapors, remove from exposure immediately; call
a physician; if breathing is irregular or stopped, start resuscitation and administer oxygen. EYES: flush
with water for at least 15 min.; Toxicity by Inhalation (Threshold Limit Value): 200 ppm; Short-Term
Exposure Limits: Data not available; Toxicity by Ingestion: Data not available; Lute Toxicity: None;
Vapor (Gas) Im’tant Characteristics: Vapors cause a slight smarting of the eyes or respiratory system
if present in high concentrations. The effect is temporary; Liquid or Solid Irritant Characteristics:
Minimum hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of
the skin; Odor 27zreshold: Data not available.

Health Hazards Information Recommended Personal Protective Equipment: Self-contained breathing
~
apparatus; rubber gloves; chemical goggles; Symptoms Following Exposure: Moderate toxicity when
swallowed. Contact with eyes causes minor irritation no worse than that caused by hand soap; General
Treatment for Exposure: INHALATION: move victim to fresh air at once; give oxygen if breathing
is difficult or artificial respiration if breathing has stopped; call a doctor. INGESTION: make victim
vomit by sticking a finger down the throat or by giving strong, warm water to drink; get medical
attention. SKIN AND EYES: remove chemical by flushing with plenty of clean, running water; remove
contaminated clothing and wash exposed skin with soap and water; Toxicity by Inhalation (Threshold
Limit Value): Data not available; Short-TemEnposure Limits: Data not available; Toxicity by Ingestion:
Data not available; Late Taricity: Not pertinent; Vapor (Gas) Irritant Characteristics: Vapors cause a
slight smarting of the eyes or respiratory system if present in high concentrations. The effect is
temporary; Liquid or Solid Irritant Characteristics: Minimum hazard. If spilled on clothing and allowed
to remain, may cause smarting and reddening of the skin; Odor Threshold Data not available.
