Section 4 - FIRST AID MEASURES
SWALLOWED
路 For advice, contact a Poisons Information Centre or a doctor at once.
路 Urgent hospital treatment is likely to be needed.
路 If swallowed do NOT induce vomiting.
路 If vomiting occurs, lean patient forward or place on left side (head-down position, if
possible) to maintain open airway and prevent aspiration.
路 Observe the patient carefully.
路 Never give liquid to a person showing signs of being sleepy or with reduced awareness;
i.e. becoming unconscious.
路 Give water to rinse out mouth, then provide liquid slowly and as much as casualty can
comfortably drink.
路 Transport to hospital or doctor without delay.
EYE
If this product comes in contact with the eyes:
路 Immediately hold eyelids apart and flush the eye continuously with running water.
路 Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and
moving the eyelids by occasionally lifting the upper and lower lids.
路 Continue flushing until advised to stop by the Poisons Information Centre or a doctor,
or for at least 15 minutes.

Section 4 - FIRST AID MEASURES
SKIN
If skin contact occurs:
路 Immediately remove all contaminated clothing, including footwear.
路 Flush skin and hair with running water (and soap if available).
路 Seek medical attention in event of irritation.
INHALED
路 If fumes or combustion products are inhaled remove from contaminated area.
路 Lay patient down. Keep warm and rested.
路 Prostheses such as false teeth, which may block airway, should be removed, where
possible, prior to initiating first aid procedures.
路 Apply artificial respiration if not breathing, preferably with a demand valve
resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.
路 Transport to hospital, or doctor.
NOTES TO PHYSICIAN
For acute or short-term repeated exposures to highly alkaline materials:
路 Respiratory stress is uncommon but present occasionally because of soft tissue edema.
路 Unless endotracheal intubation can be accomplished under direct vision,
cricothyroidotomy or tracheotomy may be necessary.
路 Oxygen is given as indicated.
路 The presence of shock suggests perforation and mandates an intravenous line and fluid
administration.
路 Damage due to alkaline corrosives occurs by liquefaction necrosis whereby the
saponification of fats and solubilisation of proteins allow deep penetration into the
tissue.
Alkalis continue to cause damage after exposure.
INGESTION:
路 Milk and water are the preferred diluents
No more than 2 glasses of water should be given to an adult.
路 Neutralising agents should never be given since exothermic heat reaction may compound
injury.
* Catharsis and emesis are absolutely contra-indicated.
* Activated charcoal does not absorb alkali.
* Gastric lavage should not be used.
Supportive care involves the following:
路 Withhold oral feedings initially.
路 If endoscopy confirms transmucosal injury start steroids only within the first 48
hours.
路 Carefully evaluate the amount of tissue necrosis before assessing the need for surgical
intervention.
路 Patients should be instructed to seek medical attention whenever they develop
difficulty in swallowing (dysphagia).
SKIN AND EYE:
路 Injury should be irrigated for 20-30 minutes.
Eye injuries require saline. [Ellenhorn & Barceloux: Medical Toxicology].

EXPOSURE CONTROLS
The following materials had no OELs on our records
鈥? trisodium phosphate: CAS:7601- 54- 9 CAS:96337- 98- 3
MATERIAL DATA
CEL Ceiling: 5 mg/m3 (compare WEEL, 15 minute time weighted average)
The workplace environmental exposure limit (WEEL) recommended by the AIHA
is thought to be protective against eye and respiratory tract irritation.
Exposure at high levels may cause substantial discomfort. No evidence
exists for chronic or long term effects. The TLV for tetrasodium
pyrophosphate (a less alkaline salt) is 5.0 mg/m3 (8 hour time-weighted
average). Upper respiratory tract irritation occurred amongst employess
exposed occasionaly to 0.5 to 2.0 mg/m3 trisodium phosphate for up to one
hour. Primary irritation of the respiratory passages has been documented
in workers exposed to 7-10 mg/m3, for even short periods. Some
acclimatisation to the initial irritation has also been reported.
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields; or as required,
路 Chemical goggles.
路 Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens or
restrictions on use, should be created for each workplace or task. This should include a
review of lens absorption and adsorption for the class of chemicals in use and an account
of injury experience. Medical and first-aid personnel should be trained in their removal
and suitable equipment should be readily available. In the event of chemical exposure,
begin eye irrigation immediately and remove contact lens as soon as practicable. Lens
should be removed at the first signs of eye redness or irritation - lens should be
removed in a clean environment only after workers have washed hands thoroughly. [CDC

ENGINEERING CONTROLS
路 Local exhaust ventilation is required where solids are handled as powders or crystals;
even when particulates are relatively large, a certain proportion will be powdered by
mutual friction.
路 Exhaust ventilation should be designed to prevent accumulation and recirculation of
particulates in the workplace.
路 If in spite of local exhaust an adverse concentration of the substance in air could
occur, respiratory protection should be considered. Such protection might consist of:
(a): particle dust respirators, if necessary, combined with an absorption cartridge;
(b): filter respirators with absorption cartridge or canister of the right type;
(c): fresh-air hoods or masks
路 Build-up of electrostatic charge on the dust particle, may be prevented by bonding and
grounding.
路 Powder handling equipment such as dust collectors, dryers and mills may require
additional protection measures such as explosion venting.
Air contaminants generated in the workplace possess varying "escape" velocities which, in
turn, determine the "capture velocities" of fresh circulating air required to efficiently
remove the contaminant.
Type of Contaminant: Air Speed:
direct spray, spray painting in shallow booths, 1- 2.5 m/s (200- 500 f/min.)
drum filling, conveyer loading, crusher dusts,
gas discharge (active generation into zone of
rapid air motion)
grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)
speed wheel generated dusts (released at high
initial velocity into zone of very high rapid
air motion).
Within each range the appropriate value depends on:

4: Large hood or large air mass in motion 4: Small hood- local control only
Simple theory shows that air velocity falls rapidly with distance away from the opening
of a simple extraction pipe. Velocity generally decreases with the square of distance
from the extraction point (in simple cases). Therefore the air speed at the extraction
point should be adjusted, accordingly, after reference to distance from the contaminating
source. The air velocity at the extraction fan, for example, should be a minimum of 4-10
m/s (800-2000 f/min) for extraction of crusher dusts generated 2 metres distant from the
extraction point. Other mechanical considerations, producing performance deficits within
the extraction apparatus, make it essential that theoretical air velocities are
multiplied by factors of 10 or more when extraction systems are installed or used.

Section 12 - ECOLOGICAL INFORMATION
The principal problems of phosphate contamination of the environment relates to
eutrophication processes in lakes and ponds. Phosphorus is an essential plant nutrient
and is usually the limiting nutrient for blue-green algae. A lake undergoing
eutrophication shows a rapid growth of algae in surface waters. Planktonic algae cause
turbidity and flotation films. Shore algae cause ugly muddying, films and damage to
reeds. Decay of these algae causes oxygen depletion in the deep water and shallow water
near the shore. The process is self-perpetuating because anoxic conditions at the
sediment/water interface causes the release of more adsorbed phosphates from the
sediment. The growth of algae produces undesirable effects on the treatment of water for
drinking purposes, on fisheries, and on the use of lakes for recreational purposes.
Section 13 - DISPOSAL CONSIDERATIONS
路 Recycle wherever possible or consult manufacturer for recycling options.
路 Consult State Land Waste Management Authority for disposal.
路 Treat and neutralise with dilute acid at an effluent treatment plant.
