3) Hazards Identification

3.1Health Effects - Acute

Swallowed 

The material is moderately discomforting to the gastro-intestinal tract and may be harmful if swallowed in large quantity. Ingestion of anionic surfactants may produce diarrhoea, bloated stomach, and occasional vomiting.

Eye 

The dust may produce eye discomfort causing smarting, pain or redness. Direct eye contact with some anionic surfactants in high concentration can cause severe damage to the cornea. Low concentration can cause discomfort, excess blood flow, and corneal clouding and swelling. Recovery may take several days.

Skin 

The material may be slightly discomfort to the skin from repeated exposures over long periods. Anionic surfactants can cause skin redness and pain, as well as a rash. Cracking, scaling and blistering can occur. Repeated skin contact with some sulfonated surfactants has produced sensitisation dermatitis in predisposed individuals.

 Inhaled 

The dust may be discomforting to the upper respiratory tract. Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate area inhaled. Exposure to sulphonates can cause an imbalance in cellular salts and therefore cellular function. Airborne and, in some instances, minor dermal allergies.

3.2 Health Effects - Chronic

Principal routes of exposure are by accidental skin and eye contact and inhalation of generated dusts. Lignosulfates may cause eczema.

3.3 First Aid

Swallowed

Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. Observe the patient carefully. Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious. Give water (or milk) to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink. Seek medical advice.

Eye

If this product comes into contact with the eyes. Immediately hold the eyes open and wash with fresh running water.Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by iccasionally lifting the upper and lower lids. If pain persists or recurs seek medical attention. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

Skin

If product comes into contact with skin, wash affected areas thoroughly with water (and soap if available). Seek medical attention in event of irritation.

Inhaled

If fumes or combustion products are inhaled. Remove to fresh air. Lay patient down. Keep warm and rested. Protheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. If breathing is shallow or has stopped, ensure clear airway and apply resuscitation, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. Transport to

hospital, or doctor. If dust is inhaled, remove to fresh air. Encourage patient to blow nose to ensure clear breathing passages. If irritation or discomfort persists seek medical attention.

                                                                              

4)First aid Measures

Ensure an eye bath and safety shower are available and ready for use.

Advice to Doctor

Treat symptomatically.

 

5) Fire and Explosion Data

 

Fire / Explosion 

Solid which exhibits difficult combustion or is difficult to ignite. Avoid generating dust, particularly clouds or dust in a confined or unventilated space as dusts may form an explosive mixture with air, and any source of ignition , i.e.flame or spark, will cause fire or explosion. Dust clouds generated by the fine grinding of the solid are a particular hazard; accumulations of fine dust may burn rapidly and fiercely if ignited . Dry dust can also be charged electrostaticcally by turbulence, pneumatic transport, pouring, in exhaust ducts and during transport. Buil-up of electrostatic charge nay be prevented by bonding and grounding. Powder handling equipment such as dust collectors, dryers and mills may require additional protection measures such as explosion venting. Combustion products include carbon monoxide (CO) and sulfur oxides (SOx) Avoid contamination with oxidising agents i.e. nitrates, oxidising acids, chlorine bleaches, pool chlorine etc. as ignition may result.

 

6) Accidental Release Measures

 

Spills

Clean up all spills immediately. Avoid contact with skin and eyes. Remove all ignition sources. Control personal contact by using protective equipment. Major spills, no smoking, naked lights or ignition sources. Clear area of personnel and move up upwind. Alert Fire Brigade and tell them location and nature of hazard. Control personal contact by using protective equipment and dust respirator. Prevent spillage from entering drains, sewers or water courses. Recover product wherever possible. Avoid generating dust. Use dry clean up precedures and avoid generating dust. Place in a suitable labelled container for waste disposal. Major spills, Sweep up/ shovel up. If required, wet with water to prevent dusting. Put residues in labelled plastic bags or other containers for disposal. Wash area down with large quantity of water and prevent runoff into drains. If contamination of drains or waterways occurs, advise emergency services.1

 Disposal

REcycle wherever is possible or consult manufacturer for recycling options. Consult State Land Waste Authority for disposal. Bury or incinerate residue at an approved site. Recycle containers if possible or dispose of in an authorised landfill.

 

7) Handling and Storage

 

Keep dry, store in original containers. Keep containers securely sealed. No smoking, containers securely sealed. No smoking, naked lights or ignition sources. Store in a cool, dry, well-ventilated area. Store away from incompatible materials and foodstuff containers. Protect containers against physical damage and check regularly for leaks. Observe manufacturer's storing and handling recommendations. Glass and plastic are suitable containers Multi-ply woven plastic or paper bag with sealed plastic liner. Note bags should be stacked, blocked, interlocked, and limited in height so that they are stable and secure against sliding or collapse. Check all containers are clearly labelled and free from leaks.

8) Exposure Controls and Personal Protection

 

8.1 Exposure Standards

TLV (8hrs) : 5 mg/m3 (inert organic dust).

8.2 Engineering Controls

Local 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.

8.3 Personal Protection

Eye protection: No special equipment for minor exposure i.e. when handling small quantities. Contact lenses pose a special hazard; soft lenses may absorb irritants and all lenses concentrate them. Hands/Feet protection: No special needed when handling small quantities. Otherwise wear chemical protective gloves, eg. PVC. Other: Wear overalls, eyewash unit. Respiratory protection: Wear appropriate respirator.
