Guidance on Safe Use
Administrative data
First-aid measures
EYE CONTACT
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
SKIN CONTACT
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid.
INGESTION
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.
INHALATION
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Fire-fighting measures
EXTINGUISHING MEDIA
This substance is a highly flammable liquid category 2 (CLP). Use water spray to cool fire-exposed containers. This material is lighter than water and not very soluble in water. The fire could easily be spread by the use of water in an area where the water cannot be contained. 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.
Flashpoint: 13 degrees C (closed cup).
Explosion limits LEL 1.4%, UEL 44.6%
SPECIAL FIRE FIGHTING PROCEDURES
None.
UNUSUAL FIRE & EXPLOSION HAZARDS
Highly flammable liquid and vapour. Containers may explode when heated.
SPECIFIC HAZARDS
Vapours may be heavier than air. They can spread along the ground and collect in low or confined areas.
PROTECTIVE MEASURES IN FIRE
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH -approved or equivalent, and full protective gear. Vapours may form an explosive mixture with air. Vapours can travel to a source of ignition and flash back. Use water spray to keep fire-exposed containers cool.
Accidental release measures
PERSONAL PRECAUTIONS
See below
EXPOSURE LIMITS:None listed.
USE LIMITS: Only to be handled in an industrial environment as industrial feedstock for further chemical synthesis.
.
ENVIRONMENTAL PRECAUTIONS
Take precautionary measures against discharges into the environment.
SPILL CLEAN UP METHODS
Remove all sources of ignition and absorb spilled material with inert material, then place into a suitable closed container for disposal as chemical waste. A vapour suppressing foam may be used to reduce vapours.
Water spray may reduce vapour but may not prevent ignition in closed spaces.
Handling and storage
USAGE PRECAUTIONS
Use with adequate ventilation and avoid inhalation. Avoid contact with eyes, skin or clothing.
Ground and bond containers when transferring material.
Wash thoroughly after handling and before eating, drinking or smoking.
Empty containers retain product residue and can be dangerous (highly flammable liquid and/or vapour)
Keep containers tightly closed and avoid contact with heat, sparks and flames. Do not pressurise, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
STORAGE PRECAUTIONS
To protect product quality, store in sealed container out of direct sunlight.
Keep away from heat, sparks and flames and other sources of ignition.
Store in a tightly closed container in a cool, dry and well ventilated place away from incompatible substances such as acids or strong oxidising agents

Dermal 3.46 mg/kg bw/day 1.73 mg/kg bw/day
Inhalation 3.05 mg/m3 0.753 mg/m3
The Chesar version 2.3.0 exposure model shows for this substance for indoor industrial activities taking more than 4 hours/day, with local exhaust ventilation (LEV) present (and running), provided workers wear masks with at least 90% respiratory protection and gloves with at least 90% dermal protection, the following exposures:
Inhalation (mg/m3) dermal (mg/kg/day) RCR (inh) RCR (dermal) RCR (total)
PROC1 0.003 0.003 < 0.01 < 0.01 < 0.01
Use in closed process, no likelihood of exposure
PROC2 0.155 0.014 0.051 < 0.01 0.055

PROC15 0.309 0.003 0.102 < 0.01 0.103
Use as laboratory reagent
The applied RMMs/OCs will not control the risks of the highly flammability of liquid and vapour (H225).
Notes:
• Good general ventilation is assumed in all cases (3-5 air exchanges per hour)
• LEV is considered for both inhalation and dermal exposures and its efficiencies are as follows:
o For PROC1 LEV is not an exposure modifier
o For PROC2, PROC3, PROC4, PROC5, PROC8a, PROC9 and PROC15 LEV reduces both inhalation and dermal exposure with 90%
o For PROC8b LEV reduces both inhalation and dermal exposure with 95%
The same CHESAR tool predicts the following for the relevant ERCs (ERC2, ERC6a, ERC6b) at a level of 1000 ton/y (fraction of tonnage to region = 1):
Total daily intake man via the environment regional RCR < 0.01
ERC2 = Formulation
ERC6a = Industrial use resulting in manufacture of another substance (use of intermediates)
ERC6b = Industrial use of reactive processing aids
