:: Safety, Storage , Shelf Life , Handling And Disposal ::

HYDROGEN GAS CONTINUOUSLY EVOLVES FROM THE CATALYST SLURRY. SMOKING CIGARETTE/ BIDI AND LIGHTING MATCHSTICK/ LIGHTER SHOULD BE STRICTLY PROHIBITED WHILE OPENING THE CONTAINERS OF THE CATALYST.

THE CATALYST SLURRY SHOULD BE MANUALLY STIRRED USING A THICK  WOODEN STICK TO RESTORE IT IN SUSPENSION FOR EASY AND SMOOTH TRANSFER.

CARE SHOULD BE TAKEN WHILE TRANSFERRING CATALYST SO AS TO AVOID/ MINIMISE SPILLAGE OF THE CATALYST. SKILLED PERSONNEL SHOULD BE  EMPLOYED FOR HANDLING THE CATALYST.

IN THE EVENT OF SPILLAGE OF SMALL QUANTITY, THE SPILLED MATERIAL MAY BE DEACTIVATED BY USING A 0.5 % SOLUTION OF POTASSIUM PERMANGANATE FOLLOWED BY FLUSHING THE AREA WITH SUFFICIENT WATER.

IN THE EVENT OF SPILLAGE OF SIGNIFICANT QUANTITY, THE SPILLED CATALYST SLURRY SHOULD BE COLLECTED BACK MANUALLY AND PUT IN A POLYTHENE BAG THEREAFTER BE PACKED IN A PLASTIC OR M.S.CONTAINER AND RETRIEVAL OF THE SPILLED CATALYST SHOULD BE FLUSHED WITH WATER. A 0.5 % SOLUTION OF POTASSIUM PERMANGANATE [KMNO4] MAY ALSO BE USED AS AN ADDITIONAL MEASURE.

IN THE EVENT OF CONTACT WITH SKIN, THE SKIN SHOULD BE WASHED IMMEDIATELY WITH RUNNING WATER. DRY WITH A CLEAN TOWEL AND APPLY A SOOTHING OINTMENT (viz SOFRAMYCIN)

EMPTY POLYTHENE BAGS AND CONTAINERS AFTER TRANSFER OF CATALYST SHOULD BE WASHED PROFUSELY WITH WATER BEFORE SCRAPPING THEM.

GREAT CARE SHOULD BE TAKEN IN DECIDING TEMPERATURE AND PRESSURE CONDITION AND SELECTION OF SOLVENT FOR THE HYDROGENATION REACTION.

DISPOSAL PRECAUTIONS : Nickel is  a costly metal. Do not therefore discard even such of the spent Raney Nickel Catalysts which can not be reactivated any more. Even such a material can fetch good money from the manufacturers of Nickel salts.

SAFETY PRECAUTIONS FOR STORAGE, HANDLING AND DISPOSAL AFTER USAGE ALLADIUM/ PLATINUM ON CARBON CATALYSTS

	As far as possible use wet form of the catalyst.
	Can cause fire when dry mixed with Methanol. For reactions using Methanol as solvent, first mix the catalyst with water to form a paste before charging the catalyst into the reactor.
	On its own the dry form does not catch fire but in contact with Hydrogen gas and air together it not only catches fire but can explode as well. Therefore store this material in an environment devoid  of Hydrogen. Take special care of this aspect while opening the packets of this catalyst.
	During transfer of catalyst powder from its plastic bag into the reactor can catch fire due to static charge generated due to abrasion of dry catalyst powder with plastic bag (container). Therefore do not empty out the bag into the reaction vessel at once with force. Add slowly.
	During filtration and thereafter do not allow spent catalyst to dry due to vaporization of solvent. Give D.M. Water washing after solvent removal. Pack and transport in wet cake form for recovery and regeneration.
	In the event of fire, contain it by pouring water. After fire has been put off, collect all the wet residues manually and pack the same in a plastic bag and send it to Vineeth Precious Catalysts Pvt. Ltd., Vasai, for recovery of Palladium/ Platinum metal and consequent conversion into fresh catalyst.
	Inhalation of catalyst powder can cause irritation of the respiratory tract. Therefore use mask while handling this product.
	In case of powder particles coming into contact with skin or falling into eyes, wash the affected part of the body or eyes profusely with water.
