Indian Standard CODE OF SAFETY FOR

PHOSPHORYL CHLORIDE

0. F O R E W O R D 0.1 This Indian S tandard was adopted by the Indian Standards Institution on 29 Janua ry 1981, after the draft finalized by the Chemical Hazards Sectional Committee had been approved by the Chemical Division Council .

0.2 Phosphoryl chloride, also known as phosphorus oxychloride, is used in the manufacture of cyclic and acyclic esters for plasticizers, gasoline addi t ives , hydraul ic fluids, organo-phosphorus compounds , etc. It is also used as a reagent; catalyst; and dehydrat ing, chlorinating and fire-retarding agent. It also finds use as a dopent for semi conductor grade silicon. 0.3 In the preparation of this code, assistance has been derived from the following publications:

a) Nat ional Fire Codes 12. National Fire Protection Association, 470 Atlantic Avenue, Boston, Massachussets, 1977.

b) SAX ( NI ) Dangerous properties of industrial materials 1979. Ed. 5. Van Nostrand Reinhold, New York.

1. SCOPE

1.1 This s tandard describes the properties of phosphoryl chloride ( phosphorus oxychloride ); nature of hazards associated with it; symptoms of toxicity and first aid; safety measures for controlling hazards in storage and handl ing; personnel safety; and essential infor­mat ion on packing and labelling.

2. TERMINOLOGY

2.1 For the purpose of this s tandard , the definitions given in IS : 4155-1966* and IS : 4167-1980† shall apply.

*Glossary of terms relating to chemical and radiation hazards and hazardous chemicals.

†Glossary of terms relating to air pollution ( first revesion ).

IS : 9787 - 1981

3 . PROPERTIES

3.1 Some important properties of phosphoryl chloride are as follows:

a) Chemical name b) Chemical formula c) Molecular weight d) Description

e) Boiling range, °C

f ) Freezing point, °C g) Relative density, 15.5°C/15.5°C h) Vapour density j) Refractive index ( 25/D ) k) Chemical reactivity

: Phosphorus oxychloride : P O C l 3

: 153-39 : Volatile, colourless to pale yellow,

strongly fuming liquid having pungent odour

: 105 to 109 for not less than 90 percent ( v/v )

: 2 : 1.685 : 5 3 ( air = 1 ) : 1.460 : Reacts with alcohol; reacts

violently with water wi th evolution of heat and hydrogen chloride gas, apparent as white fumes in air : corrosive to most metals in the presence of moisture

4. HAZARDS

4.1 H e a l t h H a z a r d s — Phosphoryl chloride causes severe internal i rr i tat ion a n d damage if swallowed. The vapour severely i m t a t e s the eyes, skin, and mucous membranes and all parts of respiratory system.

4.1.1 Threshold Limit Value ( TLV ) — T h e upper limit of phosphoryl chloride vapour concentration considered safe for continuous exposure is 3 mg/m 3 of air.

4.2 H e a t H a z a r d s — When heated phosphoryl chloride decomposes into hydrogen chloride and phosphorus oxides which are toxic and corrosive. On coming in contact with water it results in violent reaction and evolution of heat, which may sometimes result in explosion.

5. FIRE FIGHTING

5.1 Fire involving small amounts of combustibles may be smothered with suitable d ry chemical . Use water on combustibles burning in the vicinity of this mater ia l , but care shall be exercised as water applied

4

IS : 9787 - 1981

directly to phosphoryl chloride results in violent evolution of heat and causes splattering. Full protective clothing shall be worn while handl­ing the operation ( see 8.1 ).

6. STORAGE A N D H A N D L I N G

6.1 S t o r a g e — Utmost care should be exercised in storage of containers , their handl ing and emptying of contents. The containers should be stored in a well vent i la ted, cool and dry place, protected from sun and heat . T h e containers shall not be stored along with combustible materials particularly fibrous organic containers or with electrical or other equipment that may be corroded.

6.2 H a n d l i n g — Before moving, it should be ensured that the stoppers are properly closed and the containers are securely packed.

6.2.1 Pressure should not be applied in emptying the containers. Carboys and bottles should be completely drained before they are returned for re-packing or sale.

NOTE — In the case or any spillage of the material, flushing the spot with plenty of water is necessary

6.3 Sp i l l s a n d Leakage — All spills should be covered with sufficient amount of sodium bicarbonate. The mixture should be removed in a container such as a fibre d rums , plastic bags or car ton box for easy disposal in an incinerator and dispose by burning.

6.4 D i s p o s a l a n d W a s t e T r e a t m e n t — The waste should be trans-ferred into an evaporat ing dish containing sodium bicarbonate . T h e n , sprav with ammonia ( 6 M N H 4 O H ) while stirring and cover with crushed ice. Continue spraying with ammonia until the fumes of ammonium chloride subside and add iced water while stirring. Neutral ise and slowly transfer mixture into a drain with running water.

7. PACKING A N D LABELLING

7.1 P a c k i n g — Depending on the quant i ty , phosphoryl chloride may be packed in steel jacketed lead cylinders, nickel-lined steel drums, glass or plastics carboys or bottles

7.1.1 Small capacity carboys should be covered by close-fitting wicker or bamboo baskets and packed in a wooden slotted cra te or iron hampers . Larger capacity carboys should be packed individually in a box or metal d rum with inert cushioning and absorbent material .

7.1.2 Bottles should be packed in a wooden crate with iner t cushion­ing and absorbent mater ia l .

5

IS : 9787 - 1981

7.2 Labelling — All containers should bear, an identifying label as depicted in IS : 1260 ( Part I )-1973*.

7.2.1 The containers shall also be labelled as follows:

DANGER PHOSPHORYL CHLORIDE CAUSES SEVERE BURNS

VAPOUR IS EXTREMELY IRRITATING USE PROTECTIVE EQUIPMENT WHILE HANDLING

IN CASE OF SPILLAGE FLUSH AREA WITH PLENTY OF WATER

CAUTION BE CAREFUL WHEN MIXING WITH WATER : HEAT IS

EVOLVED

8. PERSONNEL SAFETY 8.1 While handling or emptying containers, complete protective clothing comprising goggles, suitable respirators, caps, rubber gloves, rubber boots and overalls ( which cover the neck ), should be worn. If the surface of the clothing is contaminated, it shall be thoroughly flushed before attempting to remove the protective clothing. In specific situations, self contained or supplied-air type respirators may have to be used.

8.2 Meticulous personal cleanliness should be observed in all operations. Physical examination including complete blood count, urinanalysis and chest X-ray, dental examination and X-ray should be carried out annually on personnel exposed to risk. Individuals suffering from diseases of the skin, liver, kidneys, lungs and teeth should be precluded from exposure.

9. SYMPTOMS OF TOXICITY AND FIRST AID 9.1 Symptoms of Toxicity — Phosphoryl chloride may lead to toxicity on inhalation or ingestion, causing irritation in the eyes, dermatitis and skin burns.

9.1.1 Inhalation of the vapour causes headache, weakness, vomitting, chest pain, cough, dyspnea, bronchitis and bronchopneumonia, pulmonary-edema and nephritis. 9.2 First Aid — In the case of spillage, contaminated clothing should be removed immediately and affected areas of the body washed with five percent ( m/v ) solution of copper sulphate, then with soap and water.

*Pictorical markings for handling and labelling of goods: Part I Dangerous goods ( first revision ).

6

IS : 9787 - 1981

T h e n follow usual burn therapy. For eyes immediate medical a t tent ion should be obtained.

9.2.1 In the case of inhalat ion of vapours, the affected person should be removed to open fresh air. He should be laid in a comfortable position and kept warm. Oxygen should be administered with the use of intermit tent positive pressure breathing apparatus . Bronchodilators and decongestants may be given, if necessary. Immedia t e medical at tention should be obtained.

NOTE — Recovery is usually complete in 1 to 3 weeks. However, bronchitis with asthmatic breathing may become chronic.
