TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable. Explosive.
NO open flames, NO sparks, and NO smoking. NO contact with flammable substances. NO contact with hot surfaces.
Water spray.
EXPLOSION Above 40.5°C explosive vapour/air mixtures may be formed.
Above 40.5°C use a closed system, ventilation, and explosion-proof electrical equipment. Do NOT expose to friction or shock.
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE
AVOID ALL CONTACT!

 •INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention. See Notes.
 •SKIN MAY BE ABSORBED! Redness. Pain. Blisters. Skin burns.
Protective gloves. Protective clothing.
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
 •EYES Redness. Pain. Severe deep burns.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Abdominal pain. Burning sensation. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
May explosively decompose on shock, friction, or concussion. May explode on heating. The substance is a strong oxidant and reacts violently with combustible and reducing materials. The substance is a weak acid. Attacks many metals including aluminium.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK:
Carcinogen category: 3B;
(DFG 2004).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion .

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 105°C
Melting point: 0°C
Relative density (water = 1): 1.2
Solubility in water:
miscible
Vapour pressure, kPa at 20°C: 2.6
Relative vapour density (air = 1): 2.6
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.04
Flash point:
40.5°C o.c.
Auto-ignition temperature: 200°C
Explosive limits, vol% in air: see Notes

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms.

N O T E S

Peracetic acid is always sold in solution with acetic acid and hydrogen peroxide. Explosive limits are unknown in literature, although the substance is combustible and has a flash point <61°C. Rinse contaminated clothes (fire hazard) with plenty of water. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
