Inhalation: Move to fresh air, keep individual comfortable and warm, consult a physician if symptoms like coughing or difficulty breathing appear
Ingestion: Rinse mouth, do not induce vomiting, give small quantities of water, never give anything by mouth to an unconscious person, seek medical assistance
Suitable Extinguishing Media: Use foam, dry chemical powder, or carbon dioxide; do not use water if possible due to product’s tendency to spread flames on water surfaces
Specific Hazards: Formation of toxic gases like phosphorus oxides, carbon monoxide, carbon dioxide, and phenols during combustion
Special Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus
Instructions: Isolate area, cool surrounding containers with water spray, prevent runoff from entering drains
Personal Precautions: Wear suitable personal protective equipment including gloves, goggles, and resistant clothing; ensure adequate ventilation
Environmental Precautions: Prevent product from entering drains, surface water, or soil; notify authorities in case of large spills
Spill Clean-up: Collect spillage with an absorbent non-combustible material like sand, scoop up and containerize, wash contaminated area with water, dispose of according to regulations
Handling: Use with adequate ventilation, avoid breathing dust or fumes, keep containers tightly closed, avoid contact with eyes, skin, and clothing, wear appropriate protective equipment
Storage: Store in original containers in a cool, dry, and well-ventilated area, keep away from food and drink, keep out of reach of children, avoid exposure to moisture, high temperatures, and incompatible materials like oxidizers
Engineering Controls: Provide general ventilation or local exhaust to minimize airborne exposure
Occupational Exposure Limits: No established occupational exposure limit values for RDP, but keep exposure as low as reasonably achievable
Personal Protection: Safety glasses with side-shields or chemical goggles, nitrile or latex gloves, long-sleeved protective clothing, and in case of insufficient ventilation, use a P2 or N95 rated mask
Hygiene: Do not eat, drink, or smoke during use, wash hands and face thoroughly after handling, remove contaminated clothing and wash before reuse
