IV. SELF PROTECTION GEAR
Standard exposure:American Industrial Hygiene Association (AIHA)
Benzyl alcohol: TWA - 10 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 directly exposed repeatedly without adverse effects.
Respiratory Protection:Bila ventilasi tidak mencukupi, pakai peralatan pernafasan yang sesuai.
Skin and body protection:Wear clothes that do not penetrate the protection chemicals, including boots, gloves, lab coat, full of evil clothing (apron) as appropriate, to prevent contact with skin.
Eye protection:Wear chemical goggles (chemical safety Goggles) and / or full face protection if splashing is possible the existence of this material. Place an emergency shower and eye washing facilities(eyewash) should be available in the workspace.

V. FIRST AID ACT
General advice:If symptoms continue or if in doubt, ask for medical help immediately.
Inhalation:Move victim to fresh valve area. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Provide medical help immediately.
If contact with skin:Immediately flush skin with large amounts of water for at least 15 minutes. Remove contaminated clothing and shoes. Give medical aid. Wash clothing and shoes before reuse
If contact with eyes:Immediately flush with plenty of water for at least 15 minutes with open eyelid. Provide medical help immediately.
If swallowed:Give plenty of water to drink. Never give anything by mouth to an unconscious victim. Give medical aid.

VI. FIRE ACTION Fighting
Flash point:93 o C (closed cup)
Auto ignition temperature:436 o C
Explosion limit:-
Facility fire:Dry chemical, foam or carbon dioxide. Water spray can be used to cool containers exposed to fire surface.
Means of extinguishing fires that do not conform:Do not use heavy water flow (because it can scatter and spread fire).
Fire fighting procedures:Use carbon dioxide, foam, or dry chemical to extinguish fires. Water can be used to cool the fire, but to extinction, foam or dry chemicals better. Prevent the spread of flames by fluid and flooded with water.Wear full protective clothing and full respiratory protection equipment. Use water to cool containers.
Special protective equipment for firefighters:Wear full protective clothing and full respiratory protection equipment.

VII. Dealing With The leakage
Self Protection:Wear appropriate personal protective equipment. Prevent people who are not on duty and not wearing protective equipment to not enter the area of leakage.
Environmental Protection:Do not be dumped into waterways or drainage systems without appropriate authorization.Collect contaminated water and firefighters used water, for further disposal in accordance with applicable regulations
Methods for cleaning:For small leaks
Dilute with water and cloth or absorb with an inert absorbent material is dried and enclosed in a container that is suitable for further disposal. Complete the cleaning by rinsing with water contaminated surface and dispose of according to local and regional regulations accordingly.
For large leaks
Combustible materials. Keep away from heat. Keep away from ignition sources. Close the leak if possible without risk. Complete the cleaning by rinsing with water contaminated surface and dispose of according to local and regional regulations accordingly.

VIII. Handling AND STORAGE
