2-Thiophenecarboxylic acid, 5-chloro-

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Move to fresh air and seek medical attention.

Emergency measure - Eyes: Bathe eyes with running water of sterile eye wash for at

least 15 minutes.  Transfer to hopsital for specialist eye

examination.

Emergency measure - Skin: Remove contaminated clothing unless stuck to the skin and

wash immediately with copious amounts of water and soap for

20 minutes. Obtain medical attention if symptoms develop.

Emergency measure - Ingestion: Obtain immediate medical attention

Fire-fighting measures

Recommended extinguishing agent: carbon dioxide, foam, dry powder, water spray.

Product arising from burning: Oxides of carbon and sulfur.

Product determined by test: N

Protective equipment: Wear self-contained breathing apparatus. Wear protective

clothing to prevent contact with skin and eyes.

Accidental release measures

Emergency measures in case of spillage: Avoid creating dust, use dust suppressing aid where needed.

Contain spillage, use bunding where possible. Do not allow

substance to enter soil, natural bodies of water, rivers,

sewers or water purification plants.

Absorb onto earth or inert absorbent and pickup

mechanically. Transfer to closable, labelled salvage

container for disposal by appropriate method.

Handling and storage

Handling: As for all substances not yet fully tested, precautionary

measures during handling chemicals should be considered.

With all processing steps where exposure/contact exists,

suitable chemical gloves such as Baypren, nitrile rubber or

PVC and eye protection such as goggles or safety spectacles

with side shields should be worn. Gloves should be disposed

of after use.

Contact with the skin, eyes and respiratory system must be

avoided.

During open handling dust formation must be prevented by LEV

and full respiratory protection and suitable protective

clothing such as PVC suit and air hood or full air suit

worn.

Engineering measures must be in place to ensure sufficient

extraction / exhaust ventilation and measures against

electrostatic loading.

Measures must be taken to ensure all equipment used is not a

source of ignition.

Storage: Store product in a cool, dry area.  Keep containers tightly

sealed in original packaging. Maintain good levels of

housekeeping to prevent dust build up. Tightly close

containers after use. Avoid retaining part containers.

Packaging of the substance and or preparation: Inner packaging: 20" x 24" black conductive tube sealed with

nylon tie strap.

Outer packaging: 24" x 36" Conductive Vermason black bag

(300gauge)

Outer Container: 470 x 600mm fibreboard drum

Special provisions / remarks

Remarks:

Transport: Not classified as dangerous in the meaning of transport,
however recommendations are: -


Containers should be tightly sealed and protected from the
elements.


Any equipment used should not be a source of ignition.


During transport the usual appropriate measures should be
followed to prevent against damage and spillage such as the
use of shatterproof bundles, correct stacking and paletting
to prevent against falling.


For mixed packaging, this substance must not be carried with
food and food stuffs.

SpecialProvisions

Stability and reactivity

Danger other than fire: Precaution should be taken against build up of electrostatic

charge. Ensure equipment used in handling is earthed and

all operations such as handling and packaging are earthed

where possible.

Chemical reaction with water: None reported.

Dust explosion: The substance is an organic powder. Most such powders have

the capacity to form potentially explosive dust clouds when

subject to mechanical processes. Adequate controls must be

in place to take account of this risk.

Avoid dust formation and maintain a high level of

housekeeping to prevent formation of dust deposits. Ensure

measures are in place to prevent build up of electrostatic

charge and eliminate all sources of ingition.  Handle in a

fully enclosed system where possible.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: Within the proposed use i.e. synthesis, the material is

completely converted and cannot not be recovered.

Industry - Possibility of destruction: controlled discharge: The preferred option is incineration of the substance and/or

controlled discharged to a licenced hazardous WWTF.

Industry - Possibility of destruction - incineration: Product wastes and empty containers are still hazardous and

should be decontaminated and disposed of in accordance with

local regulations.

Industry - Possibility of destruction - water purification: Not determined

Public at large - Possibility of recovery/recycling: Not applicable (Substance exclusively used as an

intermediate in the pharmaceutical industry)
