Route of exposure

Inhalation
Remove victim to fresh air and keep at rest in a position comfortable for breathing.
seek medical advice immediately.
if necessary, give oxygen
Check for possible heart rate problems
if breathing has stopped: administer artificial respiration.
Keep under medical surveillance

Skin contact
Take off immediately all contaminated clothing
after contact with skin, wash immediately with plenty of water, for at least 15 minutes.
in case of serious contamination, seek immediate hospital treatment

Eye contact
Do not wear contact lenses in any work area.
flush immediately with plenty of water, holding the eyelids open ( >15' )
Get medical advice (ophthalmologist)

Ingestion
give nothing to drink and do not induce vomiting (risk of pulmonary aspiration).
Risk of serious damage if inhaled into lungs, (caused e.g by vomiting), seek medical advice urgently.
If swallowed, rinse mouth with water (only if the person is conscious)

Protective equipment for first-aiders
if exposure is likely to exceed the occupational exposure limit, in a ventilated space, use an approved respiratory protective equipment; in confined space, use a autonomous breathing apparatus.

Indication of any medical attention no information available

Fire-fighting measures

Technical measures
call the safety and environment service immediately.
evacuate non-essential personnel
use fine spray or fog to control fire by preventing its spread and absorbing some of its heat.
keep tankage cool by continuous spraying with water (for non cryogenic storage).

Extinguishing media

Suitable
for minor fires : carbon dioxide (CO2) or powder
for more extensive fires : foam. water spray (mist) to cool the surfaces exposed to the fire.

Not to be used
do not use water jets (stick jets) for extinguishing fire since they could help to spread the flames

Special peril
complete combustion, with an excess of oxygen forms: carbon dioxide (CO2), water vapour , NOx.
partial combustion forms also: carbon monoxide (CO), soot and cracked products: aldehydes, ketones , carbon , polycyclic aromatic hydrocarbons (PCA or PAH) , etc...

Special exposure hazards
the vapour is heavier than air and explosive mixtures can accumulate in low spots: it may be ignited at some distance away from the spill resulting in flashbacks.
fire may cause pressure rise with risk of bursting and subsequent explosion
spreading of fire- and explosion hazard by liquid layers on the water surface

Protective equipment for firefighters
wear suitable breathing equipment, in case of risk of exposure to vapour or fumes.
protective clothing, goggles and self-contained breathing equipment should be made available for firemen.

EXPOSURE CONTROLS

Personal protection

Respiratory protection
local exhaust ventilation may be needed when working in a closed area; if exposure s likely to exceed the exposure limits of markers of the substance, use approved respiratory protective equipment conforming to EN 140; in confined space, use an autonomous breathing apparatus. Recommended filter type : Type A or better

Hands protection
gloves resistant to aromatic hydrocarbons

In case of immersion:
recommended material: fluorinated polymer or polyvinyl alcohol
layer thickness : all thicknesses
penetration time according to norm EN 374-3 > 480 minutes

In case of contact with spray:
recommended material: nitrile
layer thickness > 0,45 mm
penetration time according to norm EN 374-3 > 30 minimum

Remarks:
Gloves may degrade in contact with this chemical.
• Carefully check the glove for cracks or damage before reusing it, dispose of gloves where the penetration time is exceeded.
• The penetration time depends on temperature, glove material, thickness and construction.
Penetration time is measured against EN 374 in laboratory conditions corresponding to permanent static contact and is not necessarily representative of the risk in the workplace.
Contact the gloves' supplier for further information on the selection and resistance of gloves.

Skin and body protection
shower and eye fountain available.

Eye protection
goggles/spectacles
Do not wear contact lenses in any work area.

Other personal protection
where exposure is likely, protective clothing must be worn including gloves

Industrial health measures:

General:
handle in accordance with good industrial hygiene and safety procedures; avoid producing or diffusing fumes, vapour or spray into the air (particulary during loading or unloading product); avoid contact with skin and eyes; avoid splashes (suitable protective clothing, screen, aprons, etc...); do not wipe hands with cloths or rags which have been used for cleaning; remove all contaminated clothing and remove protective clothing when the work is completed; wash skin as soon as possible with soap and water; do not store near food products. When using, do not eat, drink or smoke.

Specific:
substance manufacture, use as intermediate, in formulation (blending) or used as fuel is made either mainly in closed process with no likelihood of exposure or in closed continuous process with occasional situations where controlled exposure can occur. Tasks where the intervention of workers is required are performed according to the following Risk Management Measures (RMM):
• Handle substance within a closed system (e.g. sampling collected under closed loop system) or
Ensure material transfers are under containment or extract ventilation and provide extract ventilation to points where emissions occur or
Use sophisticated forms of respiratory protection that require specialised maintenance or, at minimum, wear a mask conforming to EN140 with Type A filter or better.
The required efficiency of the RMM (e.g. efficiency of extract ventilation system) or type of RMM depends of the operational conditions. Further information can be found in the exposure scenarios.
• Wear suitable gloves tested to EN374
• Wear suitable eye protection (goggles/spectacles)

Specific:
transfer of the substance (charging/discharging) from or to vessels/large containers is performed at or (non-)dedicated facilities. Tasks where the intervention of workers is required are performed according to the following RMM:
• Handle substance within a closed system or
Ensure material transfers are under containment or extract ventilation and provide extract ventilation to points where emissions occur or
Use sophisticated forms of respiratory protection that require specialised maintenance or, at minimum, wear a mask conforming to EN140 with Type A filter or better.
The required efficiency of the RMM (e.g. efficiency of extract ventilation system) or type of RMM depends of the operational conditions. Further information can be found in the exposure scenarios.
• Wear suitable gloves tested to EN374.
• Wear suitable eye protection (goggles/spectacles)

Specific:
use of the substance in laboratory is performed at some occasions, i.e. for analyses of product samples. Tasks are performed according to the following RMM:
• Perform the tasks indoor provided that the substance is handled in a fume cupboard or under extract ventilation. Local Exhaust Ventilation (LEV) efficiency must be at least 70 %. Higher efficiency of the LEV may be required depending of the operational conditions. Further information can be found in the exposure scenarios.

• Wear suitable eye protection (goggles/spectacles)

Environmental exposure controls:

Specific:
substance manufacture, use as intermediate, in formulation (blending) or used as fuel is either mainly in closed process with no likelihood of exposure or in closed continuous process with occasional situations where controlled exposure can occur. The following RMM applies:
• If sludge is generated, it should not be applied to natural soils but should be incinerated, contained or reclaimed
• If waste of the substance is generated, external treatment and disposal of waste should comply with applicable local and/or national regulations
• Where emission of the substance occurs:
• The treatment of air emission must provide an emission removal of efficiency ranging from 0 to 95%
• The treatment of wastewater must provide an emission removal efficiency ranging from 85 to ¿ 95 %. Treatment may be on the site of production or via a municipal sewage treatment
The required removal efficiency depends on the operational conditions and the tonnage of production. Further information can be found in the exposure scenarios.
