SECTION 3 ‑ Hazards Identification

 

Emergency overview:

  • Aqueous peracetic acid is a clear liquid having a pungent odor similar to that of acetic  acid.
  • It is highly corrosive to all body parts and may be fatal if swallowed or inhaled. 
  • Exposure requires special first aid and timely medical follow-up.  \
  • Not flammable, but powerful oxidizing agent that assists combustion and decomposes in the presence of metals and alkalis and/or excessive heat leading to the buildup of pressure in un-vented containers and the risk of explosion.
 

Potential health effects:

  • Poison by ingestion.
  • Corrosive to skin and can cause serious eye damage.
  • Severely irritating to respiratory tract, potentially lethal.

        (For more information on health effects refer to Section No. 11–Toxicological Information).

 

SECTION 4 ‑ First Aid Measures

 

Eyes: 
  • Immediately flush eyes with plenty of water for at least 15 minutes (keep eyelids apart and remove contacts if easily accomplished). 
  • Seek medical aid immediately.

 

Skin:

  • Immediately flush skin with running water for at least 15 minutes while removing contaminated clothing and shoes.
  • Wash thoroughly with soap and water.  Flush contaminated clothing and shoes with water.
  •  Seek immediate medical aid immediately.

 

Ingestion:

  • Flush mouth with water. 
  •  Get immediate medical aid.
  • If conscious give several glasses of water or milk.
    Never give fluids if the victim is unconscious or having convulsions. 
  • Do not induce vomiting.

 

Inhalation:

  • Remove from exposure to fresh air immediately.
  • Keep victim warm and quiet. If not breathing, give artificial respiration.
  • Seek medical attention.

 

 

SECTION 5 ‑ Fire Fighting Measures

 

Fire/explosion hazard:
        Combustible – oxidizer – decomposition releases oxygen that can initiate or promote combustion
`        and cause pressure buildup in containers and confined spaces..

 

Flash point:
        Approximately 70 deg C (Closed Cup, 25%)

 

Flammable limits:
        Not available

 

Fire fighting procedures:

  • Use large amounts of water only to extinguish a fire.
  • Do not use powder or CO2 type extinguishers; these are not effective.
  • Use water spray to keep fire-exposed containers cool.  Fight fire from protected location or maximum distance.
    Use proper personal protective equipment and positive pressure
    self-contained breathing apparatus. .

 

 

SECTION 6 ‑ Accidental Release Measures

 

Personal precautions:

  • Emergency personnel must use full personal protective equipment (see Section 8) to prevent exposure.
  • Remove all sources of ignition. Approach release from upwind.

 

Environmental Precautions:

  • If possible, shut off the leak. 
  • Prevent liquid entering sewers without dilution.

 

Methods of cleaning up:   

  • Contain the spill with sand or similar non-combustible material.  
  • Remove all inappropriate materials (certain metals and organic materials). 
  • Dilute with large amount of water.  
  • Do not return product to container or tank due to the risk of decomposition.

 

 

SECTION 7 ‑ Handling and Storage

 

Safe handling suggestions:

  • Handle product with care and avoid any contamination (set up safety procedures)
  • Do not return product to container or tank due to the risk of contamination and decomposition.
  • Avoid contact with eyes, skin and breathing of vapors.
  • Do not confine product in unvented vessel or between closed valves.
  • Use adequate venting devices on all packagings, containers and tanks.
  • Do not use valves and pumps needing lubricants.

 

Precautions for safe handling:

  • During handling, wear personal protective equipment.
  • Drain and clean pipes and facilities before any maintenance.
  • Operate in a well-ventilated area.
  • Maintain eye wash and safety shower facilities.

 

Storage: Technical measures

  • Storage areas should be built with non-combustible materials and the floors should be impermeable and raised so that if an accidental leak occurs, peracetic acid will flow to a safe area or be retained.
  • Use vessels and equipment approved for peracetic acid
  • Use adequate venting devices on all packaging, containers and tanks.
  • Do not confine product in unvented vessel or between closed valves.
  • Containers should be checked regularly by visual observation for any signs of abnormality (e.g. bulging or temperature increase).
  • Containers must only be used for peracetic acid
  • Regularly verify the availability of water to deal with emergencies.
  • Comply with instructions regarding sizes of packagings at different temperatures.

 

Storage conditions:

  • Store in a cool (<5 deg C) and vented tank or in cooled, dark, clean and well-ventilated area.
  • Keep away from incompatible and combustible materials.

 

Incompatible materials:

  • Peracetic acid should be stored separated from organic and alkaline substances, chlorides and metals.

SECTION 10 ‑ Stability and Reactivity

 

Commercial solutions of aqueous peracetic acid produced on-site where they are consumed are usually stable for at least 24-48 hours, particularly when stored under refrigerated conditions (5 deg C or below).  There are two generally recognized mechanisms of aqueous peracetic acid decomposition:  1) In the presence of metals, alkalis and other contaminants (see below) peracetic acid decomposes to acetic acid and oxygen with the evolution of considerable heat (see below) and buildup of potentially dangerous levels of pressure in un-vented containers.  In the absence of contaminants, this decomposition reaction proceeds very slowly;  2) Aqueous peracetic acid also decomposes via the reverse reaction (where peracetic acid is produced from acetic acid and hydrogen peroxide using a mineral acid catalyst).  In the absence of catalyst, this reverse reaction, which is actually slightly endothermic (absorbs a small amount of heat), proceeds very slowly.  Refrigerated storage is recommended to minimize the decomposition of peracetic acid. 

 

Hazardous Decomposition or By‑products:

  • Peracetic acid decomposes exothermically (91.6 kJ/mole is evolved), particularly at temperatures >55 deg C, forming acetic acid and oxygen upon decomposition.

 

Hazardous Polymerization:

  • Will not occur.      

 

Conditions to Avoid:

  • Open flames, elevated temperatures and other sources of heat.

 

Incompatibility (materials to avoid):


  • Heavy metals, transitions metals and their salts cause catalytic decomposition.
  • Concentrated acids or alkali, reducing agents, dirt, ash and rust may cause spontaneous decomposition.
  • Contact with organic material, for example wood, paper and textiles may cause fire.
  • Peracetic acid reacts violently with chlorides forming chlorine gas.

 

 

SECTION 11 ‑ Toxicological Information

 

Acute toxicity:

  • Ingestion:          LD50(rat) = 1,175 mg/Kg PAA solution (2% PAA, 7%H2O2, 19% HOAc)
  • Inhalation:         LC50(rat) = 590 mg/m3 PAA solution (15% PAA, 15% H2O2, 25% HOAc)
  • Skin contact:     LD50(rat) = 12,000 mg/Kg PAA solution (2% PAA, 7% H2O2, 19% HOAc)

 

Local effects: 

  • Inhalation:   Severely irritating to respiratory tract and may cause inflammation and pulmonary edema.  Symptoms are cough, dizziness or sore throat. Higher concentration may have lethal effect.
  • Ingestion:    Ingestion causes burning necrosis of the mucous membranes of mouth, esophagus and stomach. Rapid liberation of oxygen may cause gastric distension and bleeding may lead to severe damage to the stomach. Risk of fatal damage if ingestion is substantial and medical treatment is delayed.
  • Skin contact:   Short contact with the skin causes general burning with discoloration of affected area and erythema, blistering and necrosis may occur.  Corrosive to skin (rabbit).
  • Eye contact:   Contact with eyes may produce corneal injury and irreversible damage.  Severely irritating to the eye (rabbit).


Specific effects:

  •  Sensitization:  Not sensitizing to the skin (guinea-pigs)
  • Mutagenicity:  In vitro: Positive result in Ames test (Salmonella typhimurium) .
    In vivo: No significant effects on mice (micronuclear test).
  • Carcinogenicity:  Not carcinogen to the skin (mouse 0.2 - 2.0% PAA).  PAA is not listed as carcinogen by IARC, NTP or OSHA.
  • Reproduction effects and teratogenicity:  Decreased reproduction in tests on rats (dose 0.2-1 g/kg).

 

 

SECTION 12 ‑ Ecological Information

 

Mobility:

  • Air:             Low volatility at ambient temperatures.
  • Water         Significant solubility and mobility
  • Soil            No significant adsorption

 

Persistence / degradability:
        Peracetic acid is rapidly reacted to non-toxic substances (water, carbon dioxide, oxygen)

 

Bioaccumulation:
        Peracetic acid is not bioaccumulated

 

Ecotoxicity:

  • In general, peracetic acid (PAA) causes effects on aqueous organisms at concentrations higher than 1 mg/L.  Freshwater organisms have a greater sensitivity than marine organisms.
  • PAA is an active bactericide in concentrations over 5 mg/L. The chronic toxicity of PAA is probably negligible due to reactions via hydrogen peroxide and acetic acid to non-toxic compounds (water, carbon dioxide, oxygen).
  • Fish: 48 h LC50 (Oncorhynchus mykiss) = 18 mg/L PAA solution (15% PAA, 25% H2O2, 25% HOAc)
  • Crustacean: 24 h LC50 (Daphnia magna) = 6.6 mg/L PAA solution (15% PAA, 25% H2O2, 25% HOAc)
