III. HAZARD IDENTIFICATION
F = Flammable
Xi = Irritant


Safety hazard
Fluid and highly flammable vapors. Mixture with air can form an explosive. Vapor is heavier than air and can move along the ground toward the distant ignition source and can be lit.
Potential health hazards
Harmful if swallowed, inhaled or absorbed through the skin. Can affect the central nervous system. Irritating to skin, eyes and respiratory tract. Aspiration may cause lung damage.
IV. SELF PROTECTION GEAR

Standard exposure 


:American Conference of Governmental Industrial Hygienists (ACGIH)
n-propanol: TWA - 200 ppm
TWA is the concentration average based on time (time-weighted average) for a normal 8-hour workday or 40 hours per-week when nearly all workers can be exposed to direct repeatedly without adverse effects
Respiratory Protection:If inadequate ventilation use suitable respiratory equipment.

Skin and body protection:Chemical resistant protective clothing appropriate including boots, gloves, lab coat, apron should be used to prevent contact with skin.

Eye protection:Avoid contact with eyes by using chemical Goggles with side protection or face protection when there is exposure to steam or fog, or if there is a risk of liquid splashing into the eyes. Safety showerand eyewash must be provided in all areas where this material is handled.

FIRST AID ACT V.

General advice:If symptoms continue or if in doubt, ask for medical help immediately.

Inhalation:Move victim to fresh valve. If there are symptoms of cough or respiratory problems lainnyasegera provide medical care. If not breathing give artificial respiration, if breathing is difficult give oxygen.Immediately contact your doctor.
If contact with skin:Wash immediately with soap and plenty of water, removing contaminated clothing and shoes. Wash contaminated clothing separately. If irritation persists, contact your doctor immediately.
If contact with eyes:Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

If swallowed:Rinse mouth with water. If the victim unconscious and awake, give 1-2 glasses of water or milk. Do not try vomiting unless dibiimbing by medical personnel because of the risk of lung damage. Never give anything by mouth to an unconscious victim or seizures. Immediately contact your doctor.

VI. FIRE ACTION Fighting

Flash point:25 o C (Closed Cup)
Auto ignition temperature:440 o C
Explosion limit:2.1 - 13.5 vol%
Fire Extinguisher:Water spray, alcohol resistant foams, dry chemical, carbon dioxide.

Means of extinguishing fires that do not fit:Torrential water flow



Fire fighting procedures:Use water to cool containers exposed to fire. Heating may cause expansion or decomposition that can result in container rupture. If safe, remove containers from path of fire. Spills and leaks can be doused with water, or mist in large quantities. Spills and leaks can be diluted with water to a mixture which can neither flammable.
Special protective equipment for firefighters:At the time of extinguishing fires, use full protective clothing with breathing equipment such as self-contained breathing apparatus operated in positive pressure.

VII. Dealing With The leakage

Self protection:Do not breathe vapor or mist. Avoid contact with the material spilled or leaked. Use appropriate personal protective equipment. Turn off all sources of ignition. Ventilasikan area. Keep the people who are not concerned of leakage area.
Environmental Protection:Avoid contamination of water into the sewer, water wells atausaluran. If contamination to wells or waterways has occurred, immediately notify the appropriate authorities.
Methods for cleaning :For small leaks
Use water spray to reduce vapors and assemble it with sand or other absorbent material (soil, vermiculite, silica gel) and enclosed in kontaineryang sealed for safe disposal.
:For large leaks
Weir leakage for further disposal. Do not smoke, do not have a flame apidi danger area.Ventilasikan leakage area. If possible, the spilled liquid is pumped or transferred kekontainer waste. The residual liquid is absorbed, and must be contained in separate containers. Disposal must be carried out following the laws and regulations.

VIII. Handling AND STORAGE

Handling:Use only in well-ventilated area and away darisumber ignition. Use equipment safely in certain areas where this material is used. Do not use pressure to compressed udar for charging, transferring, mixing or handling because of the danger of steam. Containers must be earthed (earthed) to avoid static charge when the agitation process or product transfer.
Storage:Store in a closed container in a cool place, well-ventilated isolated and away from heat, ignition sources and incompatible materials. Keep away from oxidizing materials. Always close the container tightly - check regularly to leakage. Do not eat, drink or smoke in the area of use or storage.

IX. AND REACTIVITY Stability

Mobility:This material does not easily evaporate and dissolve in water.

XII. Disposal

Product Disposal:This material must be enclosed and should not be dumped in rivers, drains or waterways.Reproduction of this material to dispose of remaining in environmental media, without prior treatment in accordance with the Government Regulation no. 18th Year of 1999 on Management of Hazardous and Toxic Waste
Disposal containers:Empty containers should be cleaned by rinsing with water. Containers that can not be used again should be cleaned from the steam-vapor prior to disposal. Residues may cause an explosion hazard Do not punch a hole, cutting or welding drums that have not been cleaned.Left empty packaging should be used initially or discarded after the Government Regulation No. 18 Year 1999 regarding Management of Hazardous and Toxic Waste
