Hazards Identification
Potential Acute Health Effects: Hazardous in case of skin contact (irritant), eye contact
(irritant), ingestion and inhalation. Slightly hazardous in case of skin contact (permeator).
Severe over-exposure can result in death.
Potential Chronic Health Effects: Slightly hazardous in case of skin contact (sensitizer).
CARCINOGENIC EFFECTS: N/A
MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. Mutagenic for bacteria and/or
yeast.
TERATOGENIC EFFECTS: Classified POSSIBLE for human.
DEVELOPMENTAL TOXICITY: N/A. The substance is toxic to the eyes, and may be
toxic to blood, kidneys, liver, brain, peripheral nervous system, upper respiratory tract, skin,

First Aid Measures
General measures: N/A
Skin contact: In case of contact, immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Cover the irritated skin with an
emollient. Cold water may be used. Wash clothing before reuse and thoroughly clean shoes
before reuse. Get medical attention immediately.
Serious skin contact: Wash with a disinfectant soap and cover the contaminated skin with an
anti-bacterial cream. Seek immediate medical attention.
Eye contact: Check for and remove any contact lenses and immediately flush eyes with
running water for at least 15 minutes, keeping eyelids open. Cold water may be used. Get
medical attention.
Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. Loosen tight clothing
such as a collar, tie, belt or waistband. Get medical attention immediately.
Serious indigestion: N/A
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention immediately.
Serious inhalation: Evacuate the victim to a safe area as soon as possible, loosening tight
clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If
the victim is not breathing, perform mouth-to-mouth resuscitation. WARNING: It may be
hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled
material is toxic, infectious or corrosive. Seek immediate medical attention.

Fire and Explosion Data
Flammability of the Product: Flammable.
Auto-Ignition Temperature: 464°C (867.2°F)
Flash points: CLOSED CUP: 12°C (53.6°F). OPEN CUP: 16°C (60.8°F)
Flammable limits: LOWER: 6% UPPER: 36.5%
Products of Combustion: These products are carbon oxides (CO, CO2).
Fire Hazards in Presence of Various Substances: Highly flammable in presence of open
flames and sparks, of heat. Non-flammable in presence of shocks. Explosion Hazards in Presence of Various Substances:
− Risks of explosion of the product in presence of mechanical impact: N/A.
− Explosive in presence of open flames and sparks, of heat.
Fire fighting media and Instructions: Flammable liquid, soluble or dispersed in water.
SMALL FIRE: Use DRY chemical powder. LARGE FIRE: Use alcohol foam, water spray or
fog.
Special Remarks on Fire Hazards: Explosive in the form of vapour when exposed to heat or
flame. Vapour may travel considerable distance to source of ignition and flash back. When
heated to decomposition, it emits acrid smoke and irritating fumes. CAUTION: MAY BURN
WITH NEAR INVISIBLE FLAME
Special Remarks on Explosion Hazards: Forms an explosive mixture with air due to its low
flash point. Explosive when mixed with Choroform + sodium methoxide and diethyl zinc. It
boils violently and explodes.

Accidental Release Measures
NB: Wear appropriate protective equipment/clothing including gloves before removing
any spills.
Small spill: Dilute with water and mop up, or absorb with an inert dry material and place in an
appropriate waste disposal container.
Large spill: Flammable, poisonous liquid. Keep away from heat and sources of ignition. Stop
leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do not
get water inside container and do not touch spilled material. Use water spray to reduce
vapours. Prevent entry into sewers, basements or confined areas; dike if needed. Call for
assistance on disposal. Be careful that the product is not present at a concentration level above
TLV. Check TLV on the MSDS and with local authorities.
7.
Handling and Storage
Precautions: Keep locked up and away from heat or sources of ignition. Ground all equipment
containing material. Do not ingest or breathe gas/fumes/ vapour/spray. Wear suitable
protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment. If
ingested, seek medical advice immediately and show the container or the label. Avoid contact
with skin and eyes. Keep away from incompatibles such as oxidizing agents, metals, acids.
Storage: Store in a segregated and approved area. Keep container in a cool, well-ventilated
area. Keep container tightly closed and sealed until ready for use. Avoid all possible sources of
ignition (spark or flame).

8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
− TWA: 200 from OSHA (PEL) [United States]
− TWA: 200 STEL: 250 (ppm) from ACGIH (TLV) [United States] [1999] STEL: 250
− from NIOSH [United States]
− TWA: 200 STEL: 250 (ppm) from NIOSH SKIN
− TWA: 200 STEL: 250 (ppm) [Canada]
− Consult local authorities for acceptable exposure limits.
Engineering Controls: Provide exhaust ventilation or other engineering controls to keep the
airborne concentrations of vapours below their respective threshold limit value. Ensure that
eyewash stations and safety showers are proximal to the work-station location.
Personal Protection: Splash goggles, lab coat, gloves, and vapour respirator, making sure to
use an approved/certified respirator or equivalent..
