Ingestion: Do not induce vomiting, rinse mouth with water, seek emergency medical support, monitor for breathing or swallowing problems
Symptoms: Nausea, abdominal pain, headache, blue tinge (cyanosis), breathing difficulty, visual disturbances
Flammability: Not flammable by itself, but intensifies combustion and can cause fire in contact with organic material or reducing agents
Suitable Extinguishing Media: Water spray, flooding quantities of water (do not use dry chemical, foam, or carbon dioxide)
Unsuitable Media: Never use dry chemical extinguishers or foam for this compound
Special Hazards: Reacts with combustibles, may release oxygen, can generate chlorine or hazardous fumes
Protective Equipment: Wear full protective gear and self-contained breathing apparatus; approach fire from upwind side
Advice for Firefighters: Isolate area, cool containers with water, evacuate personnel from danger zone
Personal Precautions: Evacuate area, avoid breathing dust, use suitable protective clothing and respiratory protection, prevent skin and eye contact
Environmental Precautions: Prevent spillage from reaching sewers, drains, waterways; potassium chlorate can contaminate water and cause ecological damage
Cleanup Methods: Sweep up gently with non-sparking tools, place in clean dry containers for disposal, minimize dust generation, decontaminate spill area with water when secure
Handling Guidelines: Avoid creating dust, use only in well-ventilated areas, keep away from heat, open flames, sparks, or combustible materials
Storage Requirements: Store in tightly closed containers, in cool dry place, segregate from acids, reducing agents, organic materials, finely powdered metals
Safe Practices: Use explosion-proof equipment, ground containers, control sources of ignition, maintain strict housekeeping to prevent contamination
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV; minimize exposure as much as possible
Engineering Controls: Use local exhaust ventilation, enclose process where dust can form, use explosion-proof electrical equipment
Personal Protection: Wear chemical safety goggles, face shields for splash, impervious gloves (nitrile or neoprene), lab coats or chemical-resistant coveralls
