Pentanoic acid

Stability and risk identification (Toxicology)

  • The substance is a weak acid.
  • The rate at which a harmful concentration in the air is reached by evaporation of this substance at 20 ° C cannot be indicated.
  • The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive by ingestion.

Manipulation and storage

Storage should be done separately from strong bases.

Industrial security measures

In case of fire: use powder, water spray, foam , carbon dioxide . In case of spills and leaks: Collect the liquid from the leak in covered containers. Eliminate the spilled liquid with abundant water. DO NOT allow this chemical to enter the environment.

Personal protection

To avoid inhalation: Ventilation, localized extraction or respiratory protection.

  • Use: Protective gloves.
  • Use: Face Screen
  • Do not eat, drink or smoke during work.

First aid


Provide the victim:

  • In case of inhalation: Clean air, rest. Provide medical assistance.
  • In case of skin contact: Remove contaminated clothing. Rinse the skin with plenty of water or shower. Provide medical assistance.
  • In case of eye contact: Rinse with plenty of water for several minutes (remove contact lenses if it can be done easily), then provide medical assistance.
  • In case of ingestion: Rinse mouth. DO NOT induce vomiting. Give plenty of water to drink. Provide medical assistance.
