Protective Equipment

Eyes

• Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133

Skin

• Wear appropriate protective gloves to prevent skin exposure.
• Wear appropriate protective clothing to prevent skin exposure.
  

Respiratory

• Follow the OSHA respirator regulations found in 29 CFR 1910.134. Always use a NIOSH- approved respirator when necessary.
  

Special Precautions

• Wash thoroughly after handling.
• Use with adequate ventilation.
• Ground and bond containers when transferring material.
• Avoid contact with eyes, skin, and clothing.
• Empty containers retain product residue, (liquid and/or vapor), and can be dangerous.
• Keep container tightly closed.
• Avoid contact with heat, sparks and flame.
• Avoid ingestion and inhalation.
• Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
• Wash thoroughly after handling.
• Flammable liquid.
• May cause skin irritation.
• Harmful if inhaled.
• This substance has caused adverse reproductive and fetal effects in animals.
• May cause central nervous system depression.
• Aspiration hazard.
• May be absorbed through the skin.
• Poison
• May cause liver and kidney damage.
• Causes digestive and respiratory tract irritation.
• Harmful or fatal if swallowed.
• Causes eye irritation and possible transient injury.

• Ventilation:
  • Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
• Storage:

1. Keep away from heat, sparks, and flame.
2. Keep away form sources of ignition.
3. Store in a tightly closed container.
4. Store in a cool, dry, well-ventilated area away from incompatible substances.

Toxicity

Toxicity Data

• INH MOU LC50 400 ppm/24h
• INH RAT LC50: 49 gm/m3/4H
• ORL RAT: LD50 636 mg/kg
• SKN RBT LD50 12124 mg/kg

Target Organs:

• Kidneys
• Central nervous system
• Liver

Health

Effects:

• Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Inhalation of vapor may cause respiratory tract irritation. May cause liver and kidney damage. Vapors may cause dizziness or suffocation. Overexposure may cause dizziness, tremors, restlessness, rapid heart beat, increased blood pressure, hallucinations, acidosis, kidney failure.

• Eyes: Causes eye irritation. May result in corneal injury. Vapors may cause eye irritation.

• Skin: May cause skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis. May be absorbed through the skin.

• Ingestion: Aspiration hazard. May cause irritation of the digestive tract. May cause effects similar to those for inhalation exposure. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal.

• Chronic: Prolonged or repeated skin contact may cause dermatitis. May cause cardiac sensitization and severe heart abnormalities. May cause liver and kidney damage.

First Aid:

• Inhalation: Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

• Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid immediately.

• Skin: Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.

• Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Possible aspiration hazard. Get medical aid immediately.

• Note to physician: Causes cardiac sensitization to endogenous catelcholamines which may lead to cardiac arrhythmia's. Do not use adrenergic agents such as epinephrine or pseudoepinephrine.

PEL/TLV

Fire Hazard Data

• Flash point: 40° F (4.44° C)

• Auto Ignition Temp: 896° F (480° C)

• Explosion Limits:
  • Lower: 1.1
  • Upper: 7.1

• Extinguishing Media: Use water spray to cool fire-exposed containers. Water may be ineffective. Do not use straight streams of water. For small fires, use dry chemical, carbon dioxide, water spray or regular foam. Cool containers with flooding quantities of water until well after fire is out. For large fires, use water spray, fog or regular foam.

• General Information: Containers can build up pressure if exposed to heat and/or fire. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. Flammable liquid. Can release vapors that form explosive mixtures at temperatures above the flashpoint. Use water spray to keep fire-exposed containers cool. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Vapors may be heavier than air. They can spread along the water. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Container may explode when heated.
