Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Remove to fresh air. If any trouble breathing, get immediate

medical attention. Administer artificial respiration if

breathing has ceased. If irritation or symptoms occur or

persist, consult a physician.

Emergency measure - Eyes: In case of eye contact, immediately rinse eyes thoroughly

with plenty of water. If wearing contact lenses, remove only

after initial rinse, and continue rinsing eyes for at least

15 minutes. If irritation occurs or persists, consult a

physician.

Emergency measure - Skin: In case of skin contact, while wearing protective gloves,

carefully remove any contaminated clothing, including shoes,

and wash skin thoroughly with soap and water. If irritation

or symptoms occur or persist, consult a physician.

Emergency measure - Ingestion: Rinse mouth and drink a glass of water. Do not induce

vomiting. If symptoms persist, consult a physician.

Fire-fighting measures

Recommended extinguishing agent: Carbon dioxide (CO2), extinguishing powder or water spray.

Product arising from burning: None known.

Product determined by test: N

Protective equipment: Wear full protective clothing and self-contained breathing

apparatus (SCBA).

Accidental release measures

Emergency measures in case of spillage: All spills should be handled according to site requirements

and based on precautions cited in the MSDS. In the case of

liquids, use proper absorbent materials. For laboratories

and small-scale operations, incidental spills within a hood

or enclosure should be cleaned by using a HEPA filtered

vacuum or wet cleaning methods as appropriate. For large dry

or liquid spills or those spills outside enclosure or hood,

appropriate emergency response personnel should be

notified. In manufacturing and large-scale operations, HEPA

vacuuming prior to wet mopping or cleaning is required.

Handling and storage

Handling: Sampling and splitting the material in the Warehouse is

performed within laminar airflow booths with appropriate

Personal Protective Equipment (PPE).  On the plant, Powder

Transfer System (PTS, vacuum operated), supplemented by

local exhaust ventilation (LEV) and PPE are used for all

manual handling operations. Finally, reaction mixture

solution sampling via Top Reactor Sampler (Rapid Transfer

Port).  Contained sampling unit, minimal exposure to

reaction mixture.

Observe usual precautions for handling chemicals. Ensure

adequate ventilation while handling the substance. Avoid

inhalation, contact with skin and eyes. Wear suitable

protective gloves and safety goggles. Wash thoroughly after

handling.

Schering-Plough Global Industrial Hygiene Services (GIHS)

has established standards for the Schering-Plough Industrial

Hygiene Risk Management (IHRM) Program to provide guidance

for protection of persons who handle Schering-Plough

materials, as well as materials purchased, for the research

and manufacture of Schering-Plough substances and

preparations. This program is used at all Schering-Plough

facilities worldwide. Key features of the IHRM include, but

are not limited to, Industrial Hygiene Risk Assessment

(IHRA) and Risk-Based Exposure Control Strategies (R-BECS).

IHRA is designed to evaluate each task or operation by

assessment of the hazard and potential degrees of exposure

to establish the actual risk of exposure by a worker

performing specific tasks. The health hazard of a material

is determined by Schering-Plough Global Occupational &

Environmental Toxicology and is used as the 'hazard'

component of the two-dimensional model. The hazard is

assessed against potential degrees of exposure that include

such elements as physical form of the substance, volume or

quantity used, duration and frequency of handling, etc. From

this assessment, the use of the substance is classified as

a low to high exposure risk which is then used to determine

exposure control strategies, need for industrial hygiene

monitoring, and appropriate personal protective equipment

usage. All personal protective equipment (PPE) is chosen in

accordance to local requirements and regulations and is

documented in the IHRA for that process.

The principles of the IHRA are communicated on Schering-

Plough Safety Data Sheets (SDSs) in appropriate sections

(e.g. section 8). Because of the global use of the SDSs at

all Schering-Plough facilities, specifics for PPE are not

provided on the SDS. Other operating procedures at each site

are used to communicate the use of appropriate PPE or other

handling guidance on a local level. Specific questions

associated with health hazards, handling, and disposal are

handled by appropriate safety and environmental

professionals at each site or at the corporate level.

There are two respirator types that Rathdrum operators would

typically wear when handling IPIs or APIs in open/semi-open

operations:

1. Constant flow airline breathing apparatus with hood (EN

14594:2005) or

2. Powered filtering device incorporating a hood (EN

12941:1999)

The site does have some closed processes. The respiratory

protection will be reassessed and modified as appropriate to

reflect the use of more stringently controlled conditions.

Storage: Store in a cool, dry, well ventilated area.

Packaging of the substance and or preparation: Fibre-board drums lined with two polyethylene bags.  Typical

weight of each drum, 25 kg.

Stability and reactivity

Danger other than fire: None known.

Chemical reaction with water: No dangerous decomposition is expected if used according to

manufacturer's specifications.

Dust explosion: Under normal conditions of use, this material does not

present a significant fire or explosion hazard. However,

like most organic compounds, this material may present a

dust deflagration hazard if sufficient quantities are

suspended in air. This hazard may exist where sufficient

quantities of finely divided material are (or may become)

suspended in air during typical process operations. An

assessment of each operation should be conducted and

suitable deflagration prevention and protection techniques

employed.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: The test item is designed for use in closed systems as an

intermediate in the synthesis of an active pharmaceutical

ingredient.  Therefore it is expected that it will be

consumed in the processes where it is employed.  Hence the

need for receovery/recycling of the substance does not apply

in this case.

Industry - Possibility of neutralisation: Not applicable.

Industry - Possibility of destruction: controlled discharge: Not recommended.

Industry - Possibility of destruction - incineration: Incineration is the preferred method of disposal.

Industry - Possibility of destruction - water purification: Not recommended.

Industry - Possibility of destruction - other: None.
