4. FIRST AID MEASURES Description of necessary measures according to routes of exposure Swallowed

Rinse mouth with water. Seek immediate medical attention.

Eye

Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting lower and upper eyelids occasionally.

Skin

Wipe off any excess material from skin and then immediately flush skin with large amounts of soapy water. Remove contaminated clothing and shoes. Wash clothing before re-use. Apply bandages soaked in magnesium sulfate. Seek immediate medical attention.

Inhaled

Remove victim from exposure to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention immediately.

Advice to Doctor

Treat symptomatically based on judgement of doctor and individual reactions of patient. Hydrofluoric (HF) acid burns require immediate and specialized first aid and medical treatment. Symptoms may be delayed up to 24 hours depending on the concentration of HF. After decontamination with water, further damage can occur due to penetration/absorption of the fluoride ion. Treatment should be directed toward binding the fluoride ion as well as the effects of exposure. Skin exposures can be treated with a 2.5% calcium gluconate gel repeated until burning ceases. More serious skin exposures may require subcutaneous calcium gluconate except for digital areas unless the physician is experienced in this technique, due to the potential for tissue injury from increased pressure. Absorption can readily occur through the subungual areas and should be considered when undergoing decontamination. Prevention of absorption of the fluoride ion in cases of ingestion can be obtained by giving milk, chewable calcium carbonate tablets or Milk of Magnesia to conscious victims. Conditions such as hypocalcemia, hypomagnesemia and cardiac arrhythmias should be monitored for, since they can occur after exposure.Consult a physician. Show this safety data sheet to the doctor in attendance

Medical Conditions Aggravated by Exposure

Populations that appear to be at increased risk from the effects of fluoride are individuals that suffer from diabetes insipidus or some forms of renal impairment.

5. FIRE FIGHTING MEASURES General Measures

Clear fire area of all non-emergency personnel. Stay upwind. Keep out of low areas. Eliminate ignition sources. Move fire exposed containers from fire area if it can be done without risk. Avoid generating dust.

Flammability Conditions

Product is a non-flammable solid. Not considered to be a fire hazard.

Extinguishing Media

In case of fire, use Dry powder

Fire and Explosion Hazard

Not considered to be an explosion hazard.

Hazardous Products of Combustion

Hydrogen fluoride, Sodium oxides.

Special Fire Fighting Instructions

HAZCHEM: 2Z Do NOT allow fire fighting water to reach waterways, drains or sewers. Store fire fighting water for treatment.

Personal Protective Equipment

Fire fighters should wear a positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots and gloves) or chemical splash suit.

Safety Data Sheet Sodium Fluoride Revision 3, Date 10 Dec 2015 General Response Procedure

Eliminate all sources of ignition. Increase ventilation. Avoid generating dust.

Clean Up Procedures

Contain and sweep/shovel up spills with dust binding material. Transfer to a suitable, labelled container and dispose of promptly as hazardous waste.

Containment

Stop leak if safe to do so.

Environmental Precautionary Measures

Do not allow product to reach drains, sewers or waterways. If product does enter a waterway, advise the Environmental Protection Authority or your local Waste Authority.

Evacuation Criteria

Evacuate all unnecessary personnel.

Personal Precautionary Measures

Personnel involved in the clean up should wear full protective clothing as listed in section 8.

7. HANDLING AND STORAGE Handling

Ensure an eye bath and safety shower are available and ready for use Observe good personal hygiene practices and recommended procedures. Wash thoroughly after handling. Take precautionary measures against static discharges by bonding and grounding equipment. Avoid contact with eyes, skin and clothing. Do not inhale product vapours. Avoid prolonged or repeated exposure.

Storage

Store in a cool, dry, well-ventilated area. Keep containers tightly closed when not in use. Inspect regularly for deficiencies such as damage or leaks. Protect against physical damage. Store away from incompatible materials as listed in section 10. Separate from acids and oxidizing materials. This product has a UN classification of 1690 and a Dangerous Goods Class 6.1 Toxic according to The Australian Code for the Transport of Dangerous Goods By Road and Rail.

Container

Store in original packaging as approved by manufacturer. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION General

Airborne Exposure Limits: -OSHA Permissible Exposure Limit (PEL): 2.5 mg(F)/m3 (TWA) -ACGIH Threshold Limit Value (TLV): 2.5 mg(F)/m3 (TWA)

Exposure Limits

No Data Available

Biological Limits

No information available on biological limit values for this product.

Engineering Measures

A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.

Personal Protection Equipment

RESPIRATOR: If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece particulate respirator (type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece particulate respirator (type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres (AS1715/1716). EYES: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible (AS1336/1337). HANDS: Wear impervious protective gloves (AS2161). CLOTHING: Wear impervious protective clothing, including boots, lab coat apron or coveralls, as appropriate, to prevent skin contact (AS3765/2210).

Work Hygienic Practices

Maintain eye wash fountain and quick-drench facilities in work area.
