Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Move to fresh air in case of accidental inhalation of

vapours or decomposition products. Give oxygen. Call a

physician immediately.

Emergency measure - Eyes: Flush eye(s) immediately with plenty of water.

Emergency measure - Skin: Wash off immediately with plenty of water.

Emergency measure - Ingestion: Rinse mouth. Ingest immediately about 350ml (5ml/kg body

weight) of activated charcoal slurry. Call a physician.

Fire-fighting measures

Recommended extinguishing agent: Dry chemical extinguishers or Carbon dioxide.

Product arising from burning: Nitrogen and hydrogen cyanide.

Product determined by test: N

Protective equipment: Self contained breathing apparatus.

Accidental release measures

Emergency measures in case of spillage: Use personal protective equipment. Do not breathe vapours.

Dam up. Soak up with inert absorbent material (e.g. sand,

silica gel, acid binder, universal binder, sawdust). Sweep

up and shovel into suitable containers for disposal. Do not

keep container sealed. Dispose of as special waste in

compliance with local and national regulations.

Handling and storage

Handling: Handle only in areas with appropriate exhaust ventilation.

Use protective equipment as follows:

In case of insufficient ventilation, wear suitable

respiratory equipment. Wear safety glasses with side-shields

and rubber gloves. Wash hands before breaks and at the end

of the working day.

Open drum carefully as contents may be under pressure. Avoid

breathing vapours emanating from containers upon opening.

Avoid contact with skin, eyes and clothing. Do not smoke.

Storage: Keep in a dry, cool, well ventilated place. Keep at

temperatures below 30°C. Where possible, storage under

refrigerated conditions is recommended.

Store in the original container.

Do not store together with strong oxidising agents.

Packaging of the substance and or preparation: The product will be sold in plastic pails.

SpecialProvisions

Stability and reactivity

Danger other than fire: During storage, it is possible that that partial

decomposition can give rise to the formation of hydrogen

cyanide. Care must be taken when opening the containers not

to inhale any vapour coming out of the container.

Containers must also be opened carefully, as the contents

may be under slight pressure due to partial decomposition

with consequent formation of nitrogen.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: If stored correctly, unused product can be stored for longer

periods and eventually used at a later date.

No material can be recovered after processing, as the

product is either entirely degraded/consumed or trace

quantities entrapped in the polymer matrix.

Industry - Possibility of neutralisation: The product should be rendered inactive before disposal.

The recommended method of disposal is by incineration of the

deactivated product in a flammable solvent.

The deactivation procedure is based on thermal decomposition

with consequent evolution of nitrogen. It is possible for

for hydrogen cyanide to be evolved during the procedure if

the mixture is acidified.

A recommended procedure for the deactivation of small

quantities of VAZO® 65L is as follows:

Add 750 ml of toluene into a two litre flask equipped with a

reflux condenser, heating mantle, addition funnel, nitrogen

inlet, thermocouple, overhead stirrer, hypochlorite

scrubber, and situated in a fume hood with a face velocity

of at least 60 FPM.

Heat the solvent to 100 C with agitation. Once the

temperature is reached, begin adding a 25% solution of VAZO®

65L (100g) in toluene.   Do NOT add the liquid VAZO® 65L at

temperatures below 95°C as there is a risk of a runaway

reaction from accumulated unreacted material at these

temperatures.

Add the VAZO 65L solution slowly (5 - 10 ml per minute) and

note the gas evolution and heat generation to verify the

experimental setup.

Maintain addition at a rate sufficient to keep the

temperature below 105 C. Once all the VAZO 65L has been

consumed, approximately 11 litres of nitrogen will have been

evolved.

Continue agitation of the solution for 2 -3 hours at 100 C

after the addition of the VAZO® 65L is complete.

The resultant solution can be incinerated.

WARNING. Small amounts of hydrogen cyanide can be formed

during this procedure. The system should be under a nitrogen

purge through a hypochlorite washing system. Cyanide

generation is accompanied by darkening of the mixture.

If this happens, the solution should be neutralised with

100ml of a 10% solution of sodium hydroxide containing 1% of

a quaternary ammonium salt. (Cooling water or an ice bath

should be available in case of heat build up.)
