Section 3 - HAZARDS IDENTIFICATION
Potential Health Effects
May cause eye irritation.
May cause skin irritation.
Low hazard for usual industrial handling.
May cause respiratory tract irritation. Vapors may cause dizziness or suffocation. Exposure to high concentrations may cause weakness, asphyxia, and death. Exposure to low concentrations may cause narcotic effects. Symptoms may include headache, dizziness, nausea, and loss of coordination.
No information found.
Section 4 - FIRST AID MEASURES
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical aid if irritation or symptoms occur.
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Section 5 - FIRE FIGHTING MEASURES
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Flammable Gas. Can form explosive mixtures at or above the flashpoint. Use water spray to keep fire-exposed containers cool. Will be easily ignited by heat, sparks or flame. Containers may explode if exposed to fire. Vapors from liquefied gas are initially heavier than air and spread along ground.
For large fires, use water spray or fog. Contact professional fire-fighters immediately. Cool containers with flooding quantities of water until well after fire is out. For small fires, use dry chemical or carbon dioxide. DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED. Do not direct water at source of leak or safety devices; icing may occur.
Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Remove all sources of ignition. Isolate area and deny entry. Provide ventilation. Prevent spreading of vapors through sewers, ventilation systems and confined areas. Stop leak only if you can do so without risk. Use water spray to reduce vapors or divert vapor cloud drift.
Section 7 - HANDLING and STORAGE
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. Take precautionary measures against static discharges. Keep container tightly closed. Keep away from 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.
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store below 50C.
Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 1333-74-0: Personal 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 or European Standard EN166.
Wear appropriate protective gloves to prevent skin exposure.
Wear appropriate protective clothing to prevent skin exposure.
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
