Fire Hazards
Oxidizer. Storage vessels involved in a fire may vent gas or rupture due to internal pressure.
Damp material may decompose exothermically and ignite combustibles. Oxygen release due
to exothermic decomposition may support combustion. May ignite other combustible materials.
Avoid contact with incompatible materials such as heavy metals, reducing agents,acids, bases,
combustibles (wood, papers, cloths etc.). Thermal decomposition releases oxygen and heat.
Pressure bursts may occur due to gas evolution. Pressurization if confined when heated or decomposing.
Containers may burst violently.
Fire-Fighting Measures
Evacuate all non-essential personnel
Wear protective clothing and self-contained breathing apparatus
Remain upwind of fire to avoid hazardous vapors and decomposition products
Use water spray to cool fire-exposed containers

6. Accidental Release Measures
Spill Clean-up Procedures
Oxidizer. Eliminate all sources of ignition. Evacuate unprotected personnel from equipment
recommendations found in Section 8. Never exceed any occupational exposure limit.
Shovel or sweep material into plastic bags or vented containers for disposal. Do not return
Remove affected person to fresh air. Seek medical attention if effects persist.
Flush eyes with running water for at least 15 minutes with eyelid held open. Seek specialist advice.
Wash affected skin with soap and mild detergent and large amounts of water.
If the person is conscious and not convulsing, give 2-4 cupfuls of water to dilute the chemical and
seek medical attention immediately. Do not inducing vomiting.spilled or contaminated material to inventory.
Flush remaining area with water to remove trace residue and dispose of properly. Avoid direct discharge
to sewers and surface waters. Notify authorities if entry occurs.
Do not touch or walk through spilled material. Keep away from combustibles (wood, paper,oils, etc.).
Do not return any product to container because of the risk of contamination.

7. Handling and Storage
Storage
Potassium monopersulfate should be stored in cool, dry areas, away from combustible chemicals,
and sources of heat such as space heaters and light fixtures.
Prolonged storage at ambient temperatures of greater than 32 degree C should be avoided.
Pallets of 25 kg bags can be stacked if there are 2-3 in of air space between them; however, pallets should
be stacked no more than two high unless local fire codes permit higher stacking.
Torn bags and product spillage must be thoroughly cleaned up and removed from the area.
Potassium monopersulfate decomposition will be accelerated on contact with moisture.
Product packaging includes a water-resistant liner, but storage conditions should also include provisions for prevention of contact with water, including high airborne humidity.
Handling
Avoid contact with eyes, skin, and clothing. Use with adequate ventilation.
Do not swallow. Avoid breathing vapors, mists, or dust. Do not eat, drink, or smoke in work area.
Prevent contact with combustible or organic materials.
Label containers and keep them tightly closed when not in use. Wash thoroughly after handling.

8. Exposure Controls/Personal Protection
Engineering Controls
General room ventilation is required. Local exhaust ventilation, process enclosures or other engineers
controls may be needed to maintain airborne levels below recommended exposure limits.
Avoid creating dust or mist. Maintain adequate ventilation. Do not use in closed or confined spaces.
Keep levels below exposure limits. To determine exposure levels,monitoring should be performed regularly.
Respiratory Protection
For many conditions, no respiratory protection may be needed; however, in dusty or unknown atmospheres
or when exposures exceed limit values, wear a NIOSH approved respirator.
Eye/Face Protection
Wear chemical safety goggles and a full face shield while handling this product.
Skin Protection
Prevent contact with this product. Wear gloves and protective clothing depending on condition of use.
Protective gloves: Chemical-resistant (Recommended materials: PVC,neoprene or rubber)
Other Protective Equipment
Eye-wash station
Safety shower
Impervious clothing
Rubber boots
General Hygiene Considerations
Wash with soap and water before meal times and at the end of each work shift. Good manufacturing
practices require gross amounts of any chemical be removed from skin as soon as practical,
especially before eating or smoking.
