What are the hazards of P-xylene?

Flammability Hazard
Paraxylene is a highly flammable liquid and vapor. Its vapor is heavier than air and can spread to ignition sources, causing flashback and increasing the risk of fire and explosion.

 

Acute Health Hazards
Inhalation of p-xylene may cause dizziness, headache, drowsiness, nausea, and irritation of the nose and throat. High-concentration exposure may cause confusion, loss of coordination, coma, or death. Skin or eye contact can result in irritation, redness, and pain, potentially leading to dermatitis and severe eye damage. Ingestion may irritate the gastrointestinal tract, causing nausea, vomiting, and abdominal pain. More critically, swallowing paraxylene can be life-threatening-the substance may enter the respiratory tract and cause fatal pulmonary lesions.

 

Chronic Health and Reactivity Hazards

Long-term, repeated exposure to xylene damages liver, kidney, and bone marrow function and is suspected of potentially affecting fertility or harming fetal development. Additionally, xylene is reactive and can undergo hazardous reactions when exposed to strong oxidizing agents, strong acids, or high temperatures.

Safety information:

 

  • P-xylene is a volatile organic compound and is toxic. Avoid direct contact with the skin and inhalation of vapours.
  • Ensure adequate ventilation when using xylene to prevent concentrations from exceeding safe limits.
  • Be aware of the risk of fire and explosions, and avoid contact with oxidising agents and strong acids.
  •  If there is an accidental spill, clean it up promptly and dispose of the waste properly.
  • Store in a cool, dry place, away from heat, ignition sources and direct sunlight.
  • Before using and handling xylene, carefully read the relevant operating procedures and safety guidelines, and the safety data sheet.
