Section IV. First Aid Measures

EYE CONTACT

Causes eye irritation. Check for and remove any contact lenses. IMMEDIATELY flush eyes with running water for at least 15 minutes, keeping eyelids open. Obtain medical attention if irritation persists.

MINOR SKIN CONTACT

If the chemical touches exposed skin, such as the hands, gently and thoroughly wash the contaminated skin with running water and non-abrasive soap. Cover irritated skin with an emollient. If irritation persists, obtain medical attention. Wash contaminated clothing before reusing.

EXTENSIVE SKIN
CONTACT

No additional information.

MINOR INHALATION

Repeated or prolonged inhalation of dust may lead to respiratory irritation. Loosen tight clothing around the individual's neck and waist. Allow the person to rest in a well ventilated area. Obtain medical attention if irritation persists

Over-exposure by inhalation may cause respiratory irritation. In emergency situations use proper respiratory protection to evacuate the victim to a safe area as soon as possible. Loosen tight clothing around the victim's neck and waist. Allow the victim to rest in a well ventilated area. Oxygen may be administered if breathing is difficult. If the victim is not breathing, perform artificial respiration. Obtain immediate medical attention

SLIGHT INGESTION

Never induce vomiting or give an unconscious person anything by mouth. If victim is conscious, have person drink several glasses of water or milk and INDUCE VOMITING. Obtain medical attention

No additional information

Section V. Fire and Explosion Data

THE PRODUCT IS

Non-flammable.

AUTO-IGNITION TEMPERATURE

Not applicable.

FLASH POINT

Not applicable.

FLAMMABILITY LIMITS

Not applicable.

PRODUCTS OF COMBUSTION

Material will not burn. Undergoes thermal decomposition at elevated temperatures to releasetoxic and combustible gases: ammonia, nitrogen oxides (NO, NO2…), sulfur oxides (SO2, SO3…).

FIRE HAZARD IN PRESENCE OF VARIOUS SUBSTANCES

Not applicable.

EXPLOSION HAZARD IN PRESENCE OF VARIOUS SUBSTANCES

This product is non-explosive. Sensitizer. Increases explosion hazard of ammonium nitrate when mixed together.

FIRE FIGHTING MEDIA AND INSTRUCTIONS

Material will not burn. Undergoes thermal decomposition at elevated temperatures to release toxic and combustible gases. Use extinguishing media suitable for surrounding materials.

SPECIAL REMARKS ON
FIRE HAZARDS

Non combustible. Flammable/toxic gases will form at elevated temperatures (>280 °C) by thermal decomposition (ammonia, sulfur oxides, nitrogen oxides). A self contained breathing apparatus should be used to avoid inhalation of toxic fumes.

No additional remark.

Section VI. Accidental Release Measures

SMALL SPIL

Use appropriate tools to put the spilled solid in a suitable container for intended use or disposal.

Prevent additional discharge of material, if possible to do so without hazard. Prevent spills from entering sewers, watercourses, wells, etc. Product will promote algae growth and may degrade water quality and taste. Notify downstream water users. Sulphate in potable drinking water should be maintained below 500mg/L. Will dissolve and disperse in water. Reclaiming material may not be viable. Recover and place material in suitable containers for recycle, reuse, or disposal. Ensure disposal is in compliance with government requirements and local regulations.

Section VII. Handling and Storage

PRECAUTIONS

Avoid contact with skin and eyes. After handling, always wash hands thoroughly with soap and water. Do not breathe dust. Keep away from food, drink, and animal feed. Avoid contact with incompatible substances. Keep out of reach of children.

STORAGE

Store in a dry, cool and well ventilated area.

Section VIII. Exposure Controls/Personal Protection

ENGINEERING CONTROLS

Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, use ventilation to keep exposure to airborne contaminants below the exposure limit.

PERSONAL PROTECTION

The selection of personal protective equipment varies, depending upon conditions of use. Where skin and eye contact may occur as a result of brief periodic exposures, wear long sleeved clothing, coveralls, leather gloves, and safety glasses with side shields.

PERSONAL PROTECTION
IN CASE OF LARGE
RELEASE

Wear a NIOSH approved dust respirator if engineering, work practise or other control measures are not adequate to prevent overexposure. Where skin and eye contact may occur as a result of prolonged or repeated exposures, wear long sleeved clothing, coveralls, leather gloves, and safety glasses with side shields.

EXPOSURE LIMITS

TLV-TWA 10 mg/m3 as inhalable dust Ref: ACGIH 1994 Particulates Not Otherwise Classified (nuisance dust). Consult authorities for local acceptable exposure limits.
