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
FLASHPOINT 37 °C (closed cup)
EXTINGUISHING MEDIA
The substance is a low melting solid. It will be present as either a flammable liquid category 3 or a flammable solid category 2. Use water spray to cool fire-exposed containers. This material has about the same weight as water and sparingly 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.
SPECIAL FIRE FIGHTING PROCEDURES
None.
UNUSUAL FIRE & EXPLOSION HAZARDS
Flammable solid, 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.
ENVIRONMENTAL PRECAUTIONS
Take precautionary measures against discharges into the environment.
SPILL CLEAN UP METHODS
Wear a self contained breathing apparatus and appropriate personal protection. Remove all sources of ignition and use a spark-proof tool. Sweep up or absorb spilled material with inert material, then place into a suitable clean, dry and closed container for disposal as chemical waste. Avoid
generating dusty conditions. 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 a spark-proof tool and 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 (flammable solid, 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.
Store below 4°C/39°F in the flammables area.

EXPOSURE LIMITS
None listed.
USE LIMITS
Only to be handled in an industrial environment in chemical synthesis. Use explosion-proof equipment, also for ventilation. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use only under a chemical fume hood.

The main derived long-term DNELs for systemic effects are:
Workers General population

Inhalation 2.42 mg/m3 0.596 mg/m3
INDUSTRIAL WORKERS TOXICITY
The CHESAR Tool version2.3.0 exposure model for this substance shows 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 long term systemic exposures:
Inhalation (mg/m3) dermal (mg/kg/day) RCR (inh) RCR (dermal) RCR (total)
PROC1 7.00e-4 0.003 < 0.01 < 0.01 < 0.01
Use in closed process, no likelihood of exposure
PROC2 7.00e-5 0.014 < 0.01 0.02 0.02
Use in closed, continuous process with occasional controlled exposure
PROC3 7.00e-4 0.007 < 0.01 0.01 0.01
Use in closed batch process (synthesis or formulation)
PROC4 3.50e-3 0.069 < 0.01 0.1 0.101
Use in batch and other process (synthesis) where opportunity for exposure arises
PROC8b 3.50e-4 0.069 < 0.01 0.1 0.1
Transfer of chemicals from/to vessels/large containers at dedicated facilities
PROC9 7.00e-4 0.069 < 0.01 0.1 0.1
Transfer of chemicals into small containers (dedicated filling line)
PROC15 7.00e-4 0.003 < 0.01 < 0.01 < 0.01
Use of laboratory reagents in small scale laboratories
Notes:
• Good general ventilation is assumed in all cases (3-5 air exchanges per hour)
• Dustiness of the substance was set at “low”
• An advanced occupational health & safety management system is assumed
• 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 PROC8b LEV reduces both inhalation and dermal exposure with 95%
o For all other PROCs LEV reduces both inhalation and dermal exposure with 90%
The applied RMMs/OCs will not control the risks of the flammability of solid, liquid and vapour (H226/H228).
