3. HAZARDS IDENTIFICATION
Human health hazards
Safety hazards
Environmental hazards
: Harmful by inhalation. May cause moderate irritation to
skin and eyes. May cause lung damage if swallowed.
Prolonged exposure may cause organ system damage:
Central nervous system, kidney, liver, auditory system.
: Highly flammable. In use, may form flammable/explosive
vapour-air mixture. Vapours are heavier than air. Vapours
may travel across the ground and reach remote ignition
sources causing a flashback fire danger.
: Due to high evaporation rates no significant environmental
hazards. Toxic to aquatic organisms.
4. FIRST AID MEASURES
Symptoms and effects
First Aid - Inhalation
First Aid - Skin
First Aid - Eye
First Aid - Ingestion
: Irritation of the skin, eyes and respiratory tract.
Headache, nausea, dizziness, narcosis.
: Remove to fresh air. If rapid recovery does not occur,
obtain medical attention.
: Remove contaminated clothing. Wash skin with water using
soap if available. If persistent irritation occurs, obtain
medical attention.
: Flush eye with water. If persistent irritation occurs,
obtain medical attention.
: Do not induce vomiting. If rapid recovery does not occur,
obtain medical attention.

5. FIRE FIGHTING MEASURES
Specific hazards
Extinguishing media
Unsuitable extinguishing
media
Protective equipment
: Hazardous combustion products may include carbon
monoxide and formaldehyde.
Will float and can be reignited on surface water. The
vapour is heavier than air, spreads along the ground and
distant ignition is possible.
: Foam. Dry chemical powder, carbon dioxide, sand or earth
may be used for small fires only.
: Water in a jet.
: Full protective clothing and self-contained breathing
apparatus.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions
Personal protection
: Avoid contact with skin, eyes. Ventilate contaminated area
thoroughly. Do not breathe vapour. Extinguish naked
flames. Remove ignition sources. No smoking. Avoid sparks.
Evacuate the area of all non-essential personnel. Shut off
leaks, if possible without personal risk.
: Wear fluorocarbon (Viton) rubber gloves, PVC*) one-piece
suit with integral hood, safety boots - rubber, knee length.
Wear full face-piece respirator with organic vapour
canister and built-in particulate filter NPF 400 (gas only).
In a confined space, wear self-contained breathing
apparatus open circuit type NPF 2000.
*) please note that PVC has a breakthrough time of about
30 min. Viton may be a more appropriate protective
material.
Environmental precautions : Prevent contamination of soil and water. Prevent from
spreading or entering into drains, ditches or rivers by
using sand, earth, or other appropriate barriers.
Clean-up methods - small : Absorb or contain liquid with sand, earth or spill control
spillage
material. Shovel up and place in a labelled, sealable
container for subsequent safe disposal. Put leaking
containers in a labelled drum or overdrum. Scrub
contaminated surfaces with detergent solution.
Clean-up methods - large : Transfer to a labelled, sealable container for product
spillage
recovery or safe disposal. Treat residues as for small
spillage.
Other information
: Risk of explosion. Inform the emergency services if liquid
enters surface water drains. Vapour may form an explosive
mixture with air.

Recommended materials
Unsuitable materials
: Avoid contact with skin, eyes and clothing. Do not breathe
vapour. Only use in well ventilated areas. Use local
exhaust extraction. Extinguish any naked flames. Remove
ignition sources. Avoid sparks. Do not smoke. Do not empty
into drains.
: Ambient.
: Keep away from direct sunlight and other sources of heat
or ignition. Do not smoke in storage areas.
: Ambient.
: Earth all equipment.
: For containers or container linings, use stainless steel,
zinc silicate, epoxy resins
: natural, butyl, neoprene or nitrile rubbers ,most plastics

: Use local exhaust ventilation. Local guidelines on
emission limits for volatile substances must be observed
for the discharge of exhaust air containing vapour.
Hygiene measures
Respiratory protection
: Launder contaminated clothing before re
: If engineering controls do not maintain airborne
concentrations to a level which is adequate to protect
worker health, select respiratory protection equipment
suitable for the specific conditions of use and meeting
relevant legislation. Where air-filtering respirators are
unsuitable (e.g., airborne concentrations are high, risk of
oxygen deficiency, confined space) use appropriate positive
pressure breathing apparatus. Where air-filtering
respirators are suitable, select an appropriate combination
of mask and filter. Select a filter suitable for combined
particulate/organic gases and vapours [boiling point
>65 °C(149 °F)] meeting EN141. No respiratory protection is
ordinarily required under normal conditions of use.
Hand protection
: neoprene or nitrile rubber gloves (splash resistance),
or fluorocarbon rubber (Viton) gloves (good resistance for
about 6 hours)
: chemical monogoggles
: safety shoes or boots - chemical resistant
standard issue work clothes

11. TOXICOLOGICAL INFORMATION
Acute toxicity Oral
: Low toxicity, LD50 > 2000 mg/kg (rat). Ingestion of large
amounts may cause slight to moderate irritation to the
mouth, throat and gastro-intestinal tract. After swallowing
large amounts, aspiration into the lungs may cause chemical
pneumonitis, which can be fatal.
Acute toxicity Dermal
: Low toxicity, LD50 > 2000 mg/kg (rabbit).
Acute toxicity Inhalation : Moderately toxic, LC50 > 2-20 mg/l (4 h, rat).
Skin irritation
: Slight irritant, but not sufficient to trigger an EC
label.

Development toxicity
: Slight irritant, but not sufficient to trigger an EC

: Not expected to be a skin sensitiser.
: Can cause kidney damage. Repeated exposure causes liver
damage. Repeated exposure affects the nervous system.
Auditory system: prolonged and repeated exposures to high
concentrations have resulted in hearing loss in rats. Abuse
and noise interaction in the work environment may cause
hearing loss.
: Not mutagenic.
: Limited evidence of carcinogenicity. Further research is
underway.
: Not expected to be a reproductive toxicant.
: Causes slight foetotoxicity at doses which are maternally
toxic.

Sewage treatment
Other information
: Floats on water. Dissolved material evaporates rapidly
within a day from water or soil surfaces. If
product enters soil, it will be mobile and may contaminate
groundwater.
: Readily biodegradable.
Expected to persist under anaerobic conditions.
Oxidises rapidly by photo-chemical reactions in air.
: Does not bioaccumulate significantly. The calculated
Bio-concentration factor is 91. Studies indicate that the
bioaccumulation might be low r than the log Pow suggests.
